The present invention relates to a seed potato nutrient cultivation apparatus and a control method for realizing a mass production method of seed potatoes using a nutrient solution cultivation method, and more particularly, to optimize the intra-bed root zone of seed potato seedlings for cultivating tissue culture seed seedlings using nutrient cultivation technology. A cultivation device for seed potato nutrient cultivation and control method for mass production of disease-free seed potatoes that are not infected by virus and easy management of cultivation of large area by a computer program that automatically sets growth conditions according to changes in external environment. to be.

As disclosed in Korean Patent No. 423837, the conventional technique for growing seed potatoes uses an aeroponics method for producing seed potatoes by nutrient cultivation, and the cultivation technique of plants using the spray glasses immerses roots in nutrient solution or pearlite. Or it is formulated in air in a hollow styrofoam bed, which is not cultivated in the soil, and sprays nutrient solution at regular intervals to seed root seedlings at regular intervals so that the root zone is wet. A technique for growing plants.

The above-mentioned spray cultivation technology has the advantage that by controlling the spraying time and interval appropriately by installing the auxiliary device of the pump for feeding the nutrient solution such as timer and solenoid valve, it is possible to control the growth state to some extent. The change in temperature and humidity in the root zone of seed potato seedlings in the bed that absorbs amniotic fluid is severely affected by the external temperature.Therefore, the roots are severely damaged due to inflexibility to the external environment or the aging of the plant is rapidly progressing. The ups and downs of the yield of the final product had a problem.

And, as shown in Figures 2 to 4, the crops cultivated in the facility 10 using the spray-glass cultivation technology is due to the unique environment of the facility, the ground portion 15 and nutrients of the crop directly contacting the environment and Underground water 20 that absorbs moisture is excellent in adaptability to the environment, and cultivated by selecting varieties or insensitive varieties that are resistant to pests, and cultivated for the purpose of harvesting tubers in the ground, unlike leafy or fruity vegetables. For this reason, the optimal root zone environment for the growth of large numbers of seed potatoes is important.

At this time, in the production of seed potatoes, a technique for correcting and maintaining the concentration (EC), pH, water temperature, root zone temperature, and liquid supply time of the nutrient solution to the root zone of seed potato seedlings is important. Therefore, when the root part of the root zone is easily changed or deteriorated in the external environment, the primary physiological and secondary pathological disorders are caused by not only root damage and decay, but also imbalance of water and moisture absorption, resulting in stable and healthy growth of seed potato seedlings. The reality is that it is not possible to achieve a large number of seed potatoes (tubers), which is the purpose of cultivating the seed plants.

Specifically, in the production of seed potatoes, symptom expression of various physiological disorders of seed potato seedlings grown under the supply of nutrient solution in the facility is exposed to environmental stress due to exposure of seed potato seedlings to the unsuitable growing environment for a few minutes to several weeks before. It can be seen that. As a result, if these physiological disturbances can be eliminated in advance, they may play an important role in increasing the growth, productivity and quality of the crop.

In addition, nutrient cultivation producers who produce seed potatoes generally have uniform nutrient solution and PH, EC (conductivity), or increase EC and feeding time to the root zone of seed potato seedlings. This increase is thought to be good crop growth and final yield. However, this technical concept applies only to some leafy vegetables, such as lettuce, and not to fruit vegetables, tomatoes, cucumbers, melons, and especially root vegetables.

In other words, the pH, EC, temperature environment and moisture conditions of the root zone of seed potato seedlings in the nutrient solution cultivation of seed potatoes are the environment in which the plant roots are active. The optimum number of seed potatoes is expected to be adjusted by adjusting the injection interval, injection volume, PH and EC.

In addition, since the artificial measures (control) to cope with the external environmental change of seed potato seedlings described above involve the labor force and time of the grower, the grower may produce a year of farming without careful attention to management when cultivating the seed potato. Due to the excessive burden and stress that can fail, there is a problem of investing excessive labor and time in the growth period of seed potato seedlings for the success of seed potato production.

In addition, the yield of seed potato by nutrient cultivation shows a severe gap depending on the cultivation of varieties and the natural conditions of the year. In other words, unlike soil cultivation, seed potato seedlings are less susceptible to environmental changes than crude seed species (Sumi), which are difficult to form tubers. Therefore, even if the cultivation of cultivated nutrient solution is selected and cultivated with good yields, the growth stage and natural conditions (growth, welfare emergence and tuber formation environment of seed potato seedlings) growing in that year will determine success and failure. Fortunately, even though the seed nutrient cultivation was successfully carried out due to similar natural environmental conditions, the yield of the final product was small or irregular, so the seed nutrient cultivation was the subject of avoidance and fear, and it was consistent with the recognition that it was difficult. .

The present invention devised to solve the above problems is to grow the seed potato nutrient solution by disappearing the influence of the external bad environment applied to the seed potato seedlings when the planter controls the setting environment or root setting part of the root zone in accordance with the growth stage of seed potato seedlings The seed potato seedling roots in the bed are automatically grown according to weather changes, climate and seasonal changes, absorption of nutrients, nutrient absorption, crop photosynthesis rate, effective welfare and welfare centers for potatoes, and a large number of final products. Excessive burden that growers feel for growing season for success of seed potato production is possible because it is possible to create optimal environment condition for growth stage, and anyone can easily grow and grow seed potato nutrient solution, which was the object of avoidance and fear, regardless of the variety. Has the characteristic of relieving stress and stress.

Seed nutrient solution cultivation apparatus according to the present invention for achieving the above object is a nutrient solution nozzle for supplying the nutrient solution to cultivate seed potato seedlings obtained by culturing the growth point collected from the seed potato seed tested virus virus, roots A cultivation unit including a cultivation bed having a cultivation temperature sensor for measuring a temperature and an optical sensor for measuring an amount of light received by the stem; Nutrient tank containing nutrient solution containing organic and inorganic nutrients, raw water to adjust the concentration of the stock solution, acid to adjust the acidity of the stock solution, alkaline solution to quantitatively supplied nutrient solution supplied to the seed potato seedlings of the cultivation unit Coolers and heaters for transferring heat to the nutrient solution to adjust the temperature of the nutrient solution stored in the nutrient solution tank, nutrient solution temperature sensor for measuring the temperature of the nutrient solution stored in the nutrient solution tank, pH sensor for measuring acidity, concentration of the nutrient solution A nutrient solution production supply unit for supplying a nutrient solution prepared by a pump to a spray nozzle of the cultivation unit, including a concentration sensor to measure; The acid and alkaline liquid for preparing the nutrient solution in the nutrient solution manufacturing supply unit is stored in an acid and alkaline liquid tank, and the stock solution containing the organic-inorganic nutrients is stored in a stock solution tank and supplied to the nutrient solution tank by respective metering pumps. It includes a stock solution supply.

In addition, the supply of acid, alkaline liquid and stock solution to the nutrient solution production part of the stock solution supply part, and the nutrient solution production part of the nutrient solution supply production part and the supply to the cultivation part of the prepared nutrient solution were carried out at the appropriate acidity, concentration and temperature necessary for root growth of seed potato seedlings. Data for the light quantity of the cultivation part and the root zone temperature of the seed potato seedlings are transmitted to produce the nutrient solution, thereby being controlled by the control means for preparing the nutrient solution with the data of acidity, concentration, and temperature of the nutrient solution previously set.

At this time, the control means collects the acidity of the nutrient solution detected in the nutrient solution tank by the pH sensor, collects the concentration of the nutrient solution detected by the concentration sensor, acid, alkali for the nutrient solution tank of the nutrient solution manufacturing supply portion in the feed solution supply Adjust the amount of liquid and stock solution supplied.

The control means collects the root growth temperature of the seed potato seedling detected by the cultivation temperature sensor and the temperature of the nutrient solution detected by the nutrient solution temperature sensor, and adjusts the temperature of the nutrient solution by operating the cooler and the heater. The seed potato receives a constant nutrient solution flexibly coped with the surrounding environment by measuring the amount of light received by the seed potato seedlings and determining the supply time period, supply time and period of the nutrient solution required for the growth of the seed potato seedlings of the cultivation part, and the seed potato growth The nutrient solution should be supplied at different time zones, times, cycles and concentrations.

Here, the nutrient solution production supply unit includes a water level sensing control unit for detecting the water level of the nutrient solution to automatically adjust the water level of the nutrient solution tank by the control means for the nutrient solution flows to the injection nozzle of the cultivation unit to flow out Keep it.

At this time, the nutrient solution production supply part including the ultraviolet sterilization unit for circulating the nutrient solution stored in the nutrient solution tank to the upper and lower parts by the circulation pump to sterilize the impure bacteria to prevent the nutrient solution containing the germs to be supplied to the seed potato seedling and production It prevents the pests of seed potatoes that become.

The nutrient solution stored in the nutrient solution tank of the nutrient solution production supply part is supplied through a conduit to the injection nozzle of the cultivation part, and the conduit is a filter for filtering impurities of the nutrient solution and a blockage of the nutrient solution supply to the injection nozzle of the cultivation part. And a blocking sensor for transmitting the detection signal to the control means, to prevent the impurity from blocking the injection nozzle and supplying the nutrient solution abnormally, and to block the pipe or the nozzle by the impurity to the seed potato seedling. If the supply of nutrient solution is interrupted, it is detected by the control means so that the producer can know. At this time, the producer can recognize the pipeline that the supply of nutrient solution is blocked to remove impurities and resume the supply of nutrient solution.

In addition, the control method of seed potato nutrient cultivation apparatus according to the present invention is the amount of light and temperature of the growth factor of seed potato seedlings implanted in the cultivation bed dedicated to nutrient cultivation is detected by the optical sensor and the temperature sensor is converted into a digital signal and the current time information Loading the environment into a user interface window of the computer; After the environmental loading step, the nutrient solution supply time, nutrient supply time and rest time of seed potato seedlings are automatically inputted through the user interface window to automatically load and store nutrient solution supply temperature, concentration and acidity in advance according to the light quantity, temperature and time information. Nutrient solution time setting step; A data communication step of transmitting a temperature, concentration, and acidity value of the loaded nutrient solution to a nutrient solution manufacturing control unit disposed in a cultivation bed at a remote place after a predetermined communication module; After the data communication step, the control unit automatically controls the stock solution supply unit for supplying the organic-inorganic stock solution, the acid and the alkaline liquid to the nutrient solution supplying unit, and the nutrient solution supplying unit for receiving the same according to the set temperature, concentration, and acidity. A nutrient solution manufacturing step of preparing a nutrient solution having a controlled temperature, acidity, and concentration and supplying the seed solution to the seed potato seedling of the cultivation bed; And after the nutrient solution production supply step by measuring the temperature and light amount of the cultivation bed, the growth information for the seed potato seedlings by a sensor unit, by measuring the temperature, concentration, acidity of the nutrient solution of the nutrient solution production supply unit by each sensor And a growth information storage step of transmitting the data to a remote computer through the predetermined communication module and storing the data as a log file of the user.

Then, the nutrient solution supply step is to manually input the nutrient solution supply time, nutrient solution temperature, and acidity to the control unit to control the feed solution and the nutrient solution supply supply accordingly accordingly, the nutrient solution to seed seedlings of the cultivation bed A manual selection step to be supplied.

At this time, after the growth information storage step, the root portion temperature of the seed potato seedlings of the cultivation bed is measured, and if the temperature is out of a predetermined growth temperature management range, the nutrient solution of the nutrient solution production supply part is cooled or heated to the root part of the seed potato seedlings. It includes a growth temperature control step of adjusting the temperature according to the growth temperature management range.

On the other hand, the computer is a formal period (10-14 days from the official date) to establish the root zone environment for each stage of growth during seed potato nutrient solution cultivation; Stem extension and welfare emergence periods (about 15-30 days); Welfare extension (30 days to 50 days); Tuber formation period and harvesting period (from 50 days until the end of the growing season); and the root temperature of the root zone of seed potato seedlings is 22 ℃ for formal period, 20 ℃ for stem extension and welfare emergence period, and 18 for welfare extension period. In the case of the tuber forming period, and the harvesting period is maintained at 18 ℃, all of the growth stage is equipped with an automated program for controlling the temperature of the root zone by instructing the control unit to maintain the night temperature at 16 ℃. Here, the day and night maintenance temperature error range of all the growth stage is ± 1.0 ℃.

In addition, the automated program maintains the nutrient solution concentration of about 0.3 mS / cm higher than the normal liquid concentration when the seed potato seedlings are maintained at day temperature and night temperature for each stage of growth, so that the seed potatoes are harvested.

On the other hand, the present invention develops and presents an automatic management program for the optimal root cultivation environment for seed potato nutrient cultivation by computer Internet in order to realize convenient and stable large-area cultivation method and multi-harvesting seed potato nutrient cultivation. The technology and application of the optimal root zone environment for seed potato nutrient cultivation are as follows.

In order to test the carbohydrate accumulation of tubers according to the nutrient concentration (EC) in the bed root area, the time interval of the feed nutrient solution PH 5.8, the nutrient solution to be fed was 40 seconds liquid injection (300/340) at 3 minutes rest, and the temperature of the root zone was The temperature (water temperature) of the nutrient solution was artificially cooled and warmed to a minimum of 16.0 ℃ and a maximum of 19.5 ℃ according to the external temperature change, and the nutrient solution concentration was divided into nutrient and reproductive growth stages. Was fed differently, the test varieties were Sumi, yield target of more than 5g.

Table 1 shows the effect of the culture concentration on the yield according to the crop growth stage.

The culture concentration is usually electrical conductivity (EC), and the unit is expressed in mS / cm (Siemens). This is the degree of conduction of electricity to the culture medium. When the amount of various inorganic ions in the culture medium increases, the electricity easily flows, and the value increases.

 It is desirable that the culture medium does not change its composition or pH as much as possible depending on the nutrient absorption of the crop. Since the composition of the culture medium varies depending on the variety, growth stage, or various environmental factors of the crop, it is unreasonable to manage the culture solution with a constant composition from the young plant to the harvest stage. In fact, the relationship between the culture medium concentration and the inorganic element uptake of the crop shows that as seedlings start growing, the absorption and growth (growing) yield of the crop also increases as the concentration of the culture medium increases. If the abnormality is maintained, the absorption of water or potassium is suppressed in seed potato seedlings, and if the concentration of the medium is low, the balance of inorganic elements with antagonistic effects such as nitrogen and potassium, calcium and magnesium, potassium and calcium is disturbed. Carbohydrate obtained from photosynthesis was used to grow crops instead of accumulating in tubers. Therefore, EC of nutrient solution is controlled differently according to growth stage and weather condition. In general, since the transpiration is strong in the high temperature stage and the water demand is high, the concentration is controlled relatively low so that sufficient moisture can be absorbed and the low temperature stage or light quantity When there is insufficient continuous or intermittent rain for 2-3 days or when it is impossible to secure enough light due to seasonal conditions (winter), the water demand is relatively low. Therefore, the concentration is controlled slightly to suppress water absorption, excess absorption and body moisture. Suppresses overblowing of plants due to accumulation.

Table 2 shows the change in the tuber concentration of carbohydrates according to the change of nutrient concentration. The nutrient solution was cooled and warmed, and the harvesting method was applied to the step harvesting method, and the test variety was Sumi, and the growth state was constant at 179 ℃ and 184cm.

Table 2 shows the tuber accumulation state of carbohydrates according to the nutrient concentration changes.

When harvesting seed potatoes by nutrient cultivation 2 ~ 3 days before harvest, nutrient concentration affects nutrient and water absorption of crops, which has a decisive effect on growth, yield and quality, 0.3mS / cm higher than the usual supernatant concentration (1.2mS / cm). When the cm management, the moisture content of the harvested tuber can be reduced to obtain a hard tuber harvest and the weight of the final harvest tends to decrease slightly, but it can be seen from Table 2 that the quality and shelf life are improved.

In addition, in order to make the program data used in the present invention, the following internal and external conditions, that is, the temperature (liquid temperature) of the pH 5.8, EC 1.2 feed nutrient solution of the nutrient solution to be adjusted to 16 ℃ and the external monthly average temperature change is the highest in April The highest temperature was 20.2 ℃, the lowest temperature was 4.9 ℃, the highest temperature in May was 22.7 ℃, the lowest temperature was 11.9 ℃, the highest temperature in June was 27.5 ℃, and the lowest temperature was 16.4 ℃.

Table 3 is a comparison of temperature change and yield (rest time / injection time) of the root zone in the bed after the root zone nutrient solution (injection).

The number of feeding and feeding amount depends on the growth stage of the crop, the concentration of the nutrient solution, the amount of insolation, the outside temperature and the root zone temperature, the temperature of the feeding liquid, the capacity of the bed, the pressure of the motor pump and the size of the injection nozzle. Different. However, the determination of the feeding amount is the most important management matter in cultivation of seed potato nutrient solution. If the time interval of nutrient payment is short, the temperature difference of the root zone is constant due to the improvement of buffering capacity of the root zone in the bed. It can be seen that increases.

In addition, when excessive feeding occurs, the current to the tubers caused by the overgrowing of the ground and underground parts in the early and middle periods is weak, and the yield is low, and the root zone is wet, so that the nutrient absorption becomes difficult, and the growth condition of the disease is greatly reduced or the late growth is greatly reduced. Etc cause problems. In addition, drying due to extreme water supply time difference can cause the plant to restore its physiological balance due to various physiological disorders, such as forgery of plants and destruction of root root hair (damage) due to high temperature environment of the root zone. It appears as damaging enough.

Therefore, when cultivating seed potato nutrient solution, the number of feeding and feeding amount of nutrient solution is different depending on the growth stage (size) of seed potato seedling, depending on the amount of water evaporation of plants according to the daily insolation and the temperature condition (state) of root zone. It is desirable to. After nutrient injection, the time when the root zone environment reaches the maximum temperature and affects the root zone of seed potato seedlings is 13-16 hours during the day and the time to reach the minimum temperature is between 04-06 hours. It is almost identical to the temperature of the nutrient solution to be injected and the near-sphere temperature, so that the optimum time can be managed only by the temperature (liquid temperature) of the nutrient solution to be injected without the influence of the external temperature at 09-11 am and 17-18 pm.

Table 4 below is to compare the growth and yield according to the temperature of the root zone in the bed to ignore the time difference of the nutrient solution nutrient solution PH 5.8, EC 1.2 and the time interval of nutrient solution fed 3 minutes, 40 seconds The test cultivars were Sumi and the yield survey was 5g or more.

Table 4 is a comparison of growth and yield according to the temperature of the root zone in the bed.

In seed potato nutrient cultivation, temperature control is the biggest cultivation technology that influences the growth and productivity of crops.

In particular, the temperature of the subterranean root zone directly affects the root extension, crop formation, respiration, leaf growth and transpiration of crops, and is also involved in nutrient and water absorption. That is, each crop has an appropriate root zone temperature, and the root zone temperature at which the maximum growth occurs is called a family register temperature. The higher or lower damage temperature is called the high temperature limit temperature and the low temperature limit temperature. The effect of changes in nutrients and moisture absorption patterns on plants is caused by root zone temperature.

More specifically, as shown in Figure 4, increasing the temperature of the underground root zone increases the current of nutrients, moisture absorption and photosynthesis products and less distribution to other sites, thereby promoting the growth of early ground and welfare, but the next day photosynthesis The action becomes inactive, resulting in growth disorders of seed potato seedlings. In other words, it is not easy to switch from nutrient growth stage to reproductive growth stage due to the overlying ground, and rapid root aging after mid-term, nutrient and water absorption disorders, and absorption of calcium are suppressed (sedimentation in nutrient bottle), so that leaf tip blight on leaves of seed potatoes tipburn), carbohydrates produced by photosynthesis, as the root zone temperature increases, respiratory rate cancels photosynthesis, and the next day, photosynthetic current is not smooth, resulting in poor growth of tubers.

On the other hand, if the liquid temperature sprayed to reduce the temperature of the root zone is lower than 15 ° C., carbohydrates continue to occur on the leaves the next day while the current of the anabolic products due to root growth and deactivation of the root zone and the physiological disorders of the ground are not completely achieved. As the leaves become dark green and become thicker, their activity is weakened (leaving the leaves), which stops the growth of stems. This is a kind of excess carbohydrate disorder, which is most common when the night temperature is low or the low temperature duration is long.

Therefore, when the grower keeps the temperature near the root zone required at the beginning of growth, rooting and early growth tend to be rather fast, but as the metabolic activity in the body rapidly progresses, aging is promoted and later growth is achieved. The yield and yield are drastically lowered, and the later growth period and the stage harvest time are shortened, so that the overall cultivation period is shortened and the yield is reduced.

In addition, if the root zone environment is continuously maintained and maintained over 22 ~ 23 ℃ or higher, tuber shape is not elongated or elliptical or secondary growth, tuber surface is rough and epidermis color is dark, so the tuber is not good product quality. The welfare elongation is promoted under conditions suitable for the elongation of the ground stem, that is, high temperature (above 25 ° C.), and long day conditions (more than 16 hours) with a small amount of solar radiation. In cultivation, the appearance of the plant is such that the stem sprayer is visible, and this environment is a condition that inhibits tuber formation, and the length of welfare is an environment that initiates tuber formation because the kidneys are stopped almost simultaneously with tuber formation. Less than 8 hours) and less than 20 ℃. Therefore, it can be seen that the root zone temperature condition of tuber formation is a temperature condition of less than 20 ℃.

As shown in Table 4, when seed nutrient solution is cultivated, when the nutrient solution supplied to the root zone, that is, the nutrient solution is not cooled without artificial control, the liquid temperature rises under the direct influence of the outside temperature of the surrounding facilities, and is almost equal to the outside temperature. When the nutrient solution is not purified, the root zone temperature rises up to 42.7 ° C, which affects the growth of seed potato seedlings.However, even if it is relatively high during the day, lowering the nighttime temperature can produce some faithful tubers due to the accumulation of anabolic materials and current. Although the formation of the welfare and tuber hypertrophy was stopped and the respiratory activity was vigorous at the temperature of the root zone of 27-30 ℃ and higher, the consumption was higher than the accumulation of assimilation materials. Difficulty breathing and absorption of amniotic fluid into the roots due to deterioration of the roots, and the respiratory rate offsets photosynthesis. The growth of jamyo is the result of inhibition (Figure 5).

A study on the effect of the root zone temperature of the plant on the temperature distribution of the above-ground plants showed that the tomato stem temperature of 30 cm above ground was strengthened by 5 ° C by cooling the nutrient solution. It is reported that the body temperature of lettuce decreases by 0.6 ~ 1.5 ℃ when cooled around 24 ℃. The cooling of the nutrient solution to be fed is considered to be useful not only for the improvement of the root zone environment but also for the control of crop temperature.

Table 5 shows the temperature change of the cultivated bed (root zone) during the cultivation of seed potato nutrient solution in the facility

 Table 6 shows the temperature change of the cultivated bed (root zone) on cloudy days when planting seed potatoes nutrient solution

 Table 7 shows the temperature change of the cultivation bed (root zone) during rainy days cultivation of seed potato nutrient solution in the facility.

Tables 5, 6, and 7 above show the effects of weather changes (sunny days, cloudy days, rainy days) and temperature changes on the root zone of cultivation of seed potato seedling cultivation facilities. This was done to program the root zone environment control data.

The weather changes are classified into sunny days (approximately 80,000 Lux), cloudy days (approximately 30,000 Lux and less than 80,000 lux), rainy weather (approximately 30,000 Lux and less), and the nutrient solution temperature supplied to the root zone is 17 ℃. Cooling and heating to maintain and supply, the supply time interval is artificially controlled to give 3 minutes rest, 30 seconds nutrient solution.

In seed nutrient cultivation, the rhizosphere environment directly affects the growth and growth of seed potato seedlings, securing effective welfare water and welfare grounds, promoting the absorption of amniotic fluid from roots, and increasing the number of final products. It has been operated mainly for small-area cultivation due to the disadvantages that cannot be controlled to the desired environment, such as the change of weather and season, or the external low temperature and high temperature, and there have been many difficulties due to excessive efforts and labor demands of the cultivation manager. The data and program of the researched data can overcome the low growth and yield of seed potato seedlings due to the poor environmental conditions exposed to the disadvantages of seed potato production method.

By operating the 140, the temperature of the nutrient solution is controlled, the light sensor 107 measures the amount of light received by the seed potato seedling, and the feeding time zone, the supply time and the period of the nutrient solution required for the growth of the seed potato seedling of the cultivation unit (A). By determining the seed potato receives a constant nutrient solution that is flexibly cope with the surrounding environment, the nutrient solution is to be supplied at different time periods, times, cycles and concentrations according to the growth of the seed potato.

Here, the nutrient solution production supply unit (B) is a nutrient solution including a level detection control unit 150 for detecting the water level of the nutrient solution so that the level of the nutrient solution tank 135 is automatically adjusted by the control means (D) The water pressure is maintained to flow out to the injection nozzle 101 of the cultivation unit A.

At this time, the nutrient solution manufacturing supply unit (B) includes a germicidal solution including an ultraviolet sterilization unit 155 for circulating the nutrient solution stored in the nutrient solution tank 135 to the upper and lower portions by the circulation pump 152 to sterilize the impurities Preventing the feeding of nutrient solution to seed potato seedlings prevents seed potato pests.

And, the nutrient solution stored in the nutrient solution tank 135 of the nutrient solution production supply (B) is supplied through the conduit 156 to the injection nozzle 101 of the cultivation unit (A), the duct 156 is the nutrient solution Blocking sensor for blocking the supply of nutrient solution to the filter 157 for filtering impurities and the injection nozzle 101 of the cultivation unit (A) and detects the blocking and sends the detection signal to the control means (D) ( 160). In addition, the blocking sensor prevents the supply of nutrient solution by abnormal impurities blocking the injection nozzle 101, and the conduit 156 is blocked by the impurities or the injection nozzle 101 is blocked so that the nutrient solution for seed potato seedlings is blocked. When the supply is cut off, it is detected by the control means (D) and displayed as "resting" on the monitor of the computer so that the producer can know. At this time, the producer can recognize the pipeline that the supply of nutrient solution is blocked to remove impurities and resume the supply of nutrient solution.

In addition, a pipe is connected to the lower portion of the cultivation bed 110 and is supplied to the seed potato seedling of the cultivation bed 110 and the remaining nutrient solution is stored in the nutrient solution recovery tank 200 via a pipeline and then pumped by the nutrient solution tank 135. ), The remaining nutrient solution other than the amount necessary for the growth of seed potato seedlings can be prevented from being evaporated into the atmosphere and wasted.

Hereinafter, as shown in Figure 9, looks at in detail the control system configuration of the control means of the seed potato nutrient solution cultivation apparatus according to the present invention.

That is, the remote control box 200 allows the user to monitor the remote environment in real time, stores the data input by the user in a computer, and uses the stored data to supply the nutrient solution manufacturing unit at a remote location (B). ) And the operation of the motor or the liquid feed motor 158 of the pump included in the feed solution supply (C).

Communication converter (Comunication Converter) 210 is the RS-422, which improves the serial communication distance (1.5km) from the computer 180, which is much more advantageous for data transmission to the remote site. Considering the location (office or house), use RS-422 converter rather than RS-232C with short communication distance of 15m.

The sub control box (Sub Controll Box or Date logger) 220 analyzes the data transmitted from the remote location and according to the result of the nutrient supply liquid supply motor 158 and the liquid supply timer, cooler (137) attached to the manual control box 230 ) And a signal for driving (controlling) the heater 140, the pH sensor 145, the concentration sensor 147, the optical sensor 107, and the like, and the manual input includes the liquid supply time, the nutrient solution temperature, the acidity (PH), Concentration EC (or electrical conductivity) can be used, and the output is input to the manual control box 230 according to the signal value of the input to drive the manual switch MS and the sensor device.

In addition, the data received from the display part (260) and transmitted to the remote computer 180, the user of the nutrient solution supply state and feeding time, seeding nutrient solution (PH), electrical conductivity (EC) You can check the overall control status such as status.

In addition, the manual control box 230 may operate the device automatically by using the data transmitted from the computer 180 or manually, without the control of the computer 180, the timer, the temperature, It is an independent part that can operate the seed potato nutrient cultivation device by inputting other values such as PH) and concentration (EC), and prevents the malfunction and damage of the whole seed potato nutrient cultivation facility due to program malfunction and computer system failure. In addition, the switch 231 includes a switch 231 to determine whether manual control or automatic control is to be determined, and the unused parts are turned on and off so that data collisions do not occur.

And, the actuator part 240 (actuator part) portion of the operation motor, the cooler 137 and the heater 140, the stock solution and acid, alkali dosing pump 177 of the nutrient solution production supply (B) or stock solution supply (C) As a driving part, when a signal capable of driving (controlling) the remote control box 200 is received, the motor and the system installed in response to the operation.

In addition, the sensor part 250 (SenSor Part) is composed of various sensors capable of measuring the state of nutrient solution (PH, EC, nutrient solution temperature, quantity of light) and root zone environment (temperature) of seed potato seedlings. The nutrient solution temperature, pH sensor 145 and the concentration sensor 147 for measuring are submerged in the nutrient solution supplied in the nutrient solution tank 135 and measure the root zone environment (temperature) of seed potato seedlings growing in the nutrient solution plant. The cultivation temperature sensor 105 may measure the temperature of the root zone, which is installed and controlled while penetrating the cultivation bed 110. Here, since the photosynthesis amount and water evaporation amount of the seed potato seedling and the amount of water absorption and water absorption of the root zone vary depending on the amount of light irradiated by the sun, the light (insolation dose) sensor 107 measures the amount of irradiation light by installing it inside the facility rather than an external facility.

In addition, the display part 260 is a part for outputting the measured value measured by the sensor part 250 to the instrument panel so that the cultivator can visually check the display part. The display part 260 is connected to the LCD window connected to the manual control box 230. In this case, the sensor value can be checked, and in the case of a remote site, the measured data can be received through the sub control box 220 and checked on the monitor screen of the computer 180.

In addition, the target (TarGet) 270 represents the seed potato seedling growing bed 110 of the nutrient solution cultivation facility, which is the final target, and the characteristics of the electrical signal with respect to the input or sensor value performed as a result of all the above processes. The operation of the device with respect to the shape value of the connecting device transfers seed potato seedling growth cultivation bed (110).

On the other hand, the switches 201, 211, 221, 240, which are not described, are switches for controlling power supply and disconnection of each box or part.

Hereinafter, the production cultivation operation process using the seed potato seedling nutrient cultivation apparatus according to the present invention will be described with reference to the table and the data showing the nutrient solution temperature, nutrient concentration, nutrient supply time period and the feeding time of each seed potato seedling growth stage, It describes by means of describing the automatic management program for operating the system.

Root wound temperature control by seed potato seedling nutrient solution cultivation device according to the present invention is managed at a high day and night 22 ℃ until the root of the seed potato seedlings (10 ~ 14 days; planting period) after planting to become stable rooting The seedling potato seedlings until 30 days before and after the growth of the seedlings are rapidly growing due to quantitative expansion, so that the root zone temperature is 20 ℃ (stem) so that welfare can emerge from the end of the plant. Day and night control by the kidney phase and welfare emergence period, and in order to induce the height of the welfare that can be run by seed potatoes at day and night at 18 ℃ 50 days before and after (extension of the welfare period).

After 50 days, in order to induce photosynthesis current and tuber formation (tuber forming, non-waiting and harvesting period) of seed potato seedlings, the temperature environment of the root zone is controlled at 18 ℃ during the day and 16 ℃ at night. In addition, the early growth nutrient solution is sensitive to the drying of the roots, and supplies sufficient nutrient solution until securing a certain number of leaves and leaf areas (stem elongation and welfare emergence) for smooth nutrient and moisture absorption according to the root activity of the root zone.

In addition, the basic conditions under which the roots of the roots are most active and the roots reach the bottom of the cultivation plant, and the welfare kidney or tuber forming period, hypertrophy and harvesting period, which absorb the nutrient solution accumulated in the cultivation plant, are not forged and the overdose is not over-produced. As a general rule, during photosynthesis, day nutrient supply is sufficient to take into account the temperature of the root zone and the amount of water that the plant evaporates, and the night supply of the current is sufficient to rest enough that the roots of the root zone of the plant are not dry. Manage the liquid supply in a condition that minimizes possible stress.

Table 9 above shows the pH and yield of nutrient solution by comparing the yield of seed potato seedlings according to the root zone environment composition (supply time and temperature treatment) for each growth stage by applying the method or program data of the optimum root zone cultivation environment automatic management of seed potato nutrient solution cultivation according to the present invention. As described in the table, EC and liquid feeding time are adjusted and controlled according to the change of weather (light quantity and temperature), root zone control temperature, and outdoor moisture condition according to the growth condition of seed potato seedlings.

In other words, during the cultivation of seed potato nutrient solution, the environmental management of the root zone was regular (10-14 days), stem extension and welfare emergence period (before and after 30 days), welfare extension (after 50 days), tuber formation, hypertrophy and harvest (after 50 days). Separate harvesting and harvesting step by step to prevent loss of tubers due to nutrient regurgitation caused by tuber competition. After tuber formation, assimilation products made from the ground are sent to the tubers through stems and welfare and accumulated in starch form. Starch granules are distributed almost uniformly in tubers formed in the early stages of hypertrophy. Since there is contention, the current amount of the assimilation product is first applied to the larger tuber, so that the amount of the assimilar nutrient is insufficient and is taken away by nutrient regurgitation, and the small tubers are eventually lost.

This is called nutrient regurgitation. A nutrient regurgitation is a phenomenon in which accumulated assimilation products are converted into sugars, which are accumulated and taken away to a large tuber, and the tubers formed initially remain large and are not lost. As the small seed potato tuber (30) is a phenomenon that turns black, this is solved by applying the step harvest method and the optimal root zone environment.

Therefore, as shown in Table 9 and Figs. 6 and 7, the management after securing the target effective welfare to some extent is to maintain the root zone at an appropriate temperature of 18 ° C. of seed potato growth to grow the delayed aging of the crop and the harvest period. It is confirmed that the seed potato according to the extension is largely harvested, and in the latter part of the management of the root of the plant until the tuber is formed and the harvest is finished, the root zone temperature is increased during the day so that the current of carbohydrates formed by the photosynthesis can be accumulated in the tuber in a short time. Controlling to 18 ° C and nighttime 16 ° C to ensure optimal photosynthetic currents yields the best results, with a weekly yield of 56.6 / 5 / 5g.

Hereinafter, the operation process of the seed potato nutrient cultivation device according to the present invention for producing seed potato by applying the automatic management program of each growth stage as described above.

FIG. 10 is a view showing a state window of an optimal root system cultivation environment automatic management program of seed potato nutrient cultivation apparatus according to an embodiment of the present invention, and FIG. 11 is an optimum root system cultivation of seed potato nutrient cultivation apparatus according to an embodiment of the present invention.

As shown in Figs. 10 to 13, when the cultivation operator runs the computer 180 at a remote location of the cultivation unit A, according to the amount of solar radiation inside the facility measured by the light sensor 107, "Sunny day (80,000 Lux). ) "," Cloudy day (less than 80,000 lux, more than 30,000 Lux) "," Rainy day (less than 30,000 Lux) ", time setting according to each weather change (light quantity) (water supply time), The temperature (PH), concentration (EC), nutrient solution temperature (water temperature), and medium temperature (temperature of seed potato seedling cultivation bed near the root zone) can be set temperature (nutrient solution temperature). You can see the current value measured by the sensor.

In addition, 24 hours (00 to 24 hours) records of nutrient solution concentration (EC), pH (PH), nutrient solution temperature (liquid temperature), and medium temperature supplied to seed potato seedlings are compared with the control status and the status currently managed. By checking, reviewing and modifying the equipment, the optimum environment of seed potato seedlings and the failure of the operating system can be immediately confirmed by changing the operation of the device and modifying the control values.

The operation process of seed potato nutrient cultivation device receives and executes user-defined data directly controlled by the cultivation manager, and has additional functions such as storage function, addition and deletion of user-selected data table, and data update.

Here, "user-defined data" is the data obtained by the user experimentally in Table 8 above, that is, an arbitrary input value inputted by the cultivation manager for optimal environmental management (control) of the cultivated bed root zone of seed potato seedlings during cultivation of seed potato seedlings. In order to control this, input data as "Time Band", "Reset Time", "Supply Time", etc. and input data using object property. To reflect the data.

According to the weather shown in the menu of the program in Table 8, the cultivation operator enters the control value of the environmental composition of the nutrient solution cultivation seed potato seedlings to be managed (time setting: feeding time, temperature setting: nutrient solution temperature). Sunlight value of fluctuations irradiated within (Sunlight: 80,000 Lux, Cloudy: 30,000 Lux or more, 10,000 Lux or less, Rainy day: 30,000 Lux or less), depending on the amount of insolation The system is operated on each nutrient cultivation bed, taking into account capacity and water evaporation.

That is, to set the nutrient supply time of the bed where each seed potato seedling is growing, using the welfare presenter, stem kidney nutrient solution and root control program of Table 8 prepared by the present invention, first click the time setting in FIG. As shown in FIG. 11, for each "Sunny Day", "Cloudy Day" and "Rainy Day" tabs, the seedling seedling feed time, rest time, and feed time of the seed potato seedlings are inputted so as to be automatically converted according to the amount of light in the light. , Set value of nutrient solution temperature, PH, EC. As shown in Table 1 below, if the liquid supply time and liquid temperature value are set and input according to the amount of light in the facility and the temperature conditions of the root zone, it is shown in Table 10.

Example 1) Seed Potato Seed Welfare Machine, Stem Extension, Nutrient Amount and Root Power Management

Table 10 is a seed potato seedling nutrient solution supply time setting (when four seed potato seedling cultivation bed).

The optimum environmental condition conversion (nutrient feeding and root temperature) of the rooting cultivation of seed potato nutrient cultivation was carried out by the cultivation operator during the stage of growth , Tuber formation, hypertrophy and harvesting periods; from 50 days), Table 10 above. Input control to the computer as the seed potato seedling nutrient feeding time is set, and it is automatically converted according to the current time zone that is input and operated and the light quantity value irradiated in the facility, and the nutrient feeding motor is operated according to the control input value. To the bed.

As shown in FIG. 11, the window of the nutrient solution feeding time setting is for 1 minute every 8 minutes with the difference of the feeding liquid resting on the four cultivation beds from 00:00 to 03:02 on the sunny day. 7 minutes rest / 1 minute supply), an example set to supply the nutrient solution, when each bed (BED) is operated to feed the nutrient solution, the state of the bed (BED1 tap) as shown in FIG. When the liquid supply is not in operation, the "rest" status is indicated by the notation (BED2, BED3, BED4 taps), and the bed rest and supply status are recorded in the lower blank window according to the operating time for reference. .

Table 10, Seed Potato Seed Solution Feeding Time Setting, is an example of 1) Seed Potato Seed Welfare Machine, Stem Kidney Feeding Solution and Root Care Management, and Entering Feeding Time Values. Is 4 on a sunny day, the water supply (supply) time from 08:20 to 08:40 is 4 minutes 30 seconds / 30 seconds (4 minutes 30 seconds off the injection interval of nutrient solution, 30 seconds operated If you want to operate the data), enter the data input settings as time zone 08: 20-08: 40, break time 00:45, and supply time 00:30 seconds. The input value of / 30 seconds is first converted into five minutes of the nutrient solution rest time and the supply time into seconds (300 seconds), and the converted time of 300 seconds is divided by the number of cultivation beds to supply the nutrient solution (4 beds) 75 seconds. If you subtract 30 seconds from the feeding time you want to feed again, 45 seconds will be paid to each of the four cultivation beds. Prices are made every 45 seconds.

In other words, the nutrient supply liquid supplied to each seed potato nutrient cultivation bed is fed 30 seconds after the bed (BED) 1 45 seconds rest, and then operate the bed (BED) 2 according to the control signal, supplying 30 seconds after the 45 seconds rest (BED) 3 operates at the end of the 30 second feed of bed (BED) 2, followed by a 30 second feed after a 45 second break. Bed (BED) 4 is also operated for 30 seconds after 45 seconds of rest. Thus, the total break time per bed (BED) is 4 minutes 30 seconds (270 seconds) and the feeding time is 30 seconds.

This means that when the supplied nutrient solution (3 tons) is excessively fed into the cultivation bed by the feed motor operation, the nutrient solution circulated back to the original position (the nutrient solution tincture) is inclined at the natural potential energy (the slope of the cultivation bed of the cultivation plant cultivation bed). (1/500 to 1,000), the amount of nutrient solution forced by the nutrient feeding motor is greater than the amount of nutrient solution circulated and recovered, and the nutrient solution in the nutrient tank is gradually reduced and supplied into the cultivation bed due to the difference between the nutrient solution supplied and recovered. As the nutrient solution is increased, the automatic level control device of the nutrient solution tank to supplement the nutrient solution, the operation of the peripheral device to supplement the insufficient nutrient concentration (EC) and PH, etc., the cooler and the heater to maintain a constant specific heat, etc. Two planting beds at the same time to avoid excessive current and load in time, preventing the risk of fire and system shutdown due to the interruption of current Abnormally adjust so as not to supply. Therefore, when two or more cultivation beds are operated, the feeding operation is sequentially performed as bed (BED) 1 and bed (BED) 2.

The temperature environment setting of seed potato seedling root zone is suitable for the growth stage of seed potato seedling as shown in Table 9 above, and the temperature and environmental conditions of the root zone where seed potato seedlings are growing are around 22 ± 0.3 ° C during seeding seedling planting period. The nutrient solution is managed so that the emergence period is around 20 ± 0.3 ° C, the welfare extension is around 18 ± 0.3 ° C, the tuber forming period, non-atmosphere, and the harvesting period are 18 ± 0.3 ° C at night and 16 ± 0.3 ° C at night. Is cooled or warmed using a control device such as a cooling device (cooler) and a heater (electric heater).

In order to prevent the physiological damage of the seed potato seedlings grown, the liquid temperature to be sprayed is 15.0 ° C or higher, with the minimum temperature cooling limit of the liquid temperature being 15.0 ° C, which is a concern about the root zone damage of seed potato seedlings. Based on 24 ℃ where the starch content of seedlings decreases, the limit value of the maximum heating temperature of liquid temperature should be controlled to 24.9 ℃ or less. If it is impossible, increase the supply time by 5 seconds and keep the root zone temperature constant.

That is, when the nutrient solution temperature (liquid temperature) is 15.0 ℃, the liquid supply time is 2 minutes 30 seconds, 30 seconds liquid injection (2 minutes 30 seconds / 30 seconds), the root zone environment temperature 22 ± 0.3 ℃, the current seed potato seedling cultivation When the bed wound zone temperature rises above the control setting to 24.0 ° C, the liquid temperature can no longer be cooled to 15.0 ° C. Increase the control setting value of the feed time until it reaches the setting value that you want to maintain, such as 2 minutes 30 seconds, 35 seconds rapid injection, 2 minutes 30 seconds, 40 seconds rapid injection, 2 minutes 30 seconds, 45 seconds rapid injection, etc. Adjust to spray.

The following seed potato seedling nutrient feeding temperature is set in Example 1) Seedling seedling welfare seedling, stem kidney seedling nutrient feeding and root volume management, and the liquid temperature value to be inputted. The liquid temperature setting is changed according to the change of insolation and time so that the root zone temperature environment is maintained at around 20 ± 0.3 ° C in accordance with the growth stage, and the root zone temperature environment in which seed potato seedlings in the cultivation bed under control are currently growing. The media temperature is measured on a computer monitor, and the cultivation manager can adjust and control the optimum root zone environment value required by seed potato seedlings such as gradual changes in temperature and temperature rise.

 Table 11 shows seed seedling nutrient solution liquid supply temperature settings.

Therefore, the automatic management of the cultivation facilities (water supply and root zone temperature) according to the seed potato nutrient solution cultivation optimal root zone cultivation environment automatic management program is as follows. According to the signal of the light sensor that can measure the amount of sunlight in the nutrient solution cultivation facility Sunny days: 80,000 Lux, Cloudy days: 30,000 Lux or more ℃ 10,000 lux or less, Rainy days: 30,000 Lux or less The amount of nutrient solution supplied to the root zone of seed potato seedlings depends on the value of user defined data (Table 8. Seed potato nutrient solution cultivation optimal rooting environment automatic management method or program data supply time setting data and nutrient solution temperature setting data). The liquid temperature having a constant specific heat (temperature) is supplied and sprayed at a predetermined time interval to maintain the temperature of the root zone.

The nutrient solution temperature (liquid temperature) setting window shown below is the nutrient solution temperature on a sunny day. If the nutrient solution temperature is inputted as the cold temperature 11 and the warming temperature 10 from 00:00 to 11:59, the device is cooled according to the input value. When the nutrient solution is below 10 ℃ of the set value, heat the heater immersed in the nutrient solution tank to warm the nutrient solution, and when the nutrient solution rises above 11 ℃, Start the cooler.

As shown in FIG. 14, the communication port setting is used by the user as a default based on COM1, and when a communication port and a system error occur, "communication error" appears on the main screen. It is difficult to recall DATA when there are too many saved data. If you set it to 60 seconds, you can call up one data for 60 seconds and turn each relay output on and off manually. Also, after entering the relay number, press the Send key to check the operation of the relay.
