The present invention relates to a seed potato seedling cultivation bed, and more particularly to a seed potato seedling cultivation bed for producing seed potato in large quantities by nutrient solution by seed seed seedlings not infected with virus.

As disclosed in Korean Patent Application No. 2005-13313, the conventional seed potato cultivation apparatus is a nutrient solution nozzle and root for supplying nutrient solution for cultivating seed potato seedlings obtained by culturing the growth point collected from virus-tested seed potato seed. Stock solution containing a cultivation unit including a cultivation bed having a cultivation temperature sensor for measuring the temperature of the cultivation temperature and an optical sensor for measuring the amount of light received by the stem, and a raw liquid containing an inorganic nutrient for preparing a nutrient solution supplied to the seed potato seedlings of the cultivation unit. Raw water to adjust the concentration of the stock solution, acid for adjusting the acidity of the stock solution, nutrient solution tank receiving a quantitative supply of alkali, transferring heat to the nutrient solution to control the temperature of the nutrient solution stored in the nutrient solution tank Cooler and heater, nutrient solution temperature sensor for measuring the temperature of nutrient solution stored in the nutrient solution tank, pH sensor for measuring acidity, nutrient solution Including a concentration sensor for measuring the concentration of the nutrient solution production supply unit for supplying the nutrient solution produced by the pump to the injection nozzle of the cultivation unit and the acid, alkaline liquid for preparing the nutrient solution of the nutrient solution production supply unit acid, alkaline liquid tank A stock solution supplying unit for storing the stock solution containing the organic-inorganic nutrients in a stock solution tank and supplying the stock solution to the nutrient solution tank by a respective metering pump; And collecting acidity of the nutrient solution detected by the pH sensor to supply the nutrient solution prepared at the proper acidity, concentration, and temperature necessary for root growth of the seed potato seedlings of the cultivation unit to the seed potato seedlings, Collect the concentration to adjust the supply amount of acid, alkaline solution and stock solution to the nutrient solution tank of the nutrient solution production supply unit in the stock solution supply unit, and the growth temperature of the root portion of the seed potato seedling detected by the cultivation temperature sensor and the nutrient solution temperature sensor Collect the temperature of the nutrient solution, operate the cooler and the heater to adjust the temperature of the nutrient solution, measure the amount of light received by the seed potato seedlings with the optical sensor, and determine the supply time and supply amount of nutrient solution required for the growth of seed potato seedlings of the cultivation unit Thereby controlling the supply time period and the supply amount of the nutrient solution.

Here, the seed potato nutrient cultivation apparatus uses a nutrient cultivation method for producing seed potato by formulating seed potato seedlings, using an aeroponics method for spraying and supplying nutrient solution to the root zone of seed potato seedlings using a nutrient solution injection nozzle. The cultivation bed to be used is a fruit-vegetable cultivation bed used for growing vegetables or flowers by the nutrient cultivation method, or a cultivation bed made by a grower or a nutrient plant using general commercial panel styrofoam.

In addition, the conventional cultivation bed has a lower upper and lower width of the cultivation bed, so that the roots of the root zone are full or tangled, and the temperature and moisture of the root zone are leaked out between the gaps of the cultivation bed, or the external bad environment is introduced or the surface of the bed bottom is produced. The temperature and humidity of the root zone change according to the spraying interval which is injected by rapid discharge of nutrient solution.

Thereafter, when the grower formalizes and grows the seedling seedlings, the rapidly changing outdoor environment is directly influenced by the high temperature and low temperature repeatedly in the growing department, so that the nutrient and moisture absorption of the seedling seedlings, the growth and respiration of roots The higher the root zone temperature, the higher the respiratory volume, and the higher the temperature, the more the respiratory volume offsets the photosynthetic amount, thereby inhibiting growth. Therefore, the effect of inhibiting the growth and transpiration of leaves on the ground and the absorption of calcium are suppressed. Tipburn appears.

In addition, the pathogen due to the high temperature contact of the root zone is widespread, so that the seed potato and the welfare decay, or the disease occurs, the frequent increase of the nutrient solution in order to lower the temperature of the elevated root zone occurs due to the excessive coverage of moisture.

On the contrary, when the temperature in the root zone is low, it affects the nutrient absorption pattern of the roots, which suppresses the absorption of phosphate, potassium, and magnesium, resulting in more absorption of ammonia nitrogen than nitrate nitrogen. Gives.

As a result of the above problems, the seed potato seedlings are stressed and the growth of seed potato seedlings is stopped or the growth is delayed. Due to the low water yield, proper environment composition of the root zone is a key factor in determining the thorax, and it is currently the fact that the grower avoids cultivation of the nutrient solution by disrupting the final seed yield.

Therefore, some studies have been conducted to improve the above problems caused by nutrient cultivation by maintaining or adjusting environmental adjustments to light, temperature, and moisture in the root zone of seed potato seedlings, but have not suggested a fundamental alternative.

On the other hand, the spray mirror method does not immerse roots in nutrient solution or cultivate them in pearlite or soil, but instead of planting the roots of seed potato seedlings in a hollow styrofoam cultivation bed that blocks light so that root respiration of crops can be performed smoothly. After exposure to air in the interior, a sufficient amount of oxygen can be supplied to the roots by cultivating the nutrient solution while spraying the roots at defined time intervals.

In addition, the pump and other equipment of the pump, such as the electronic valve is installed, the injection time and interval is adjusted appropriately, the nutrient solution is sprayed to the root zone of the seed potato seedlings, the growth state can be adjusted according to the absorption characteristics of nutrients and moisture of the crop There is this.

However, it is difficult to create the root zone environment of seed potato seedlings in the cultivation bed because the spray mirror method is severely affected by the temperature in the bed, that is, the outside air temperature change, and the frequent change of temperature and humidity in the root zone due to the discontinuous injection time interval of nutrient solution. The roots are severely damaged due to lack of buffering capacity or the seed potato seedlings that are growing may be stressed. When the grower sprays and supplies frequent nutrient solution to maintain the root zone temperature required for the cultivation of seed potato seedlings, the water formed in the seed potato is excessively watered. There has been a problem that the supply of chamomile and hypertrophy occur.

In addition, the hydroponic method is used to compensate for the shortcomings of the above-mentioned intra-bed root zone environment of the spray mirror, the hydroponic method is to immerse the root of the seed potato seedlings in the nutrient solution, and to cultivate by spraying the nutrient solution to the un-locked root zone. The buffering capacity against temperature changes in the root zone was improved, but the roots were immersed in the nutrient solution, which made it difficult for oxygen supply to the roots, and the welfare of the potatoes and the seed potatoes were immersed in the culture solution. It has drawbacks that lead to degradation and reduced production.

Here, the hypertrophy of the skin is a physiological disorder occurring in the epidermis of the skin and is a pore that serves to supply oxygen to the potato cells through which gas is exchanged through these skins. When the seed potato formed in the welfare of seed potato seedlings is submerged in the supplied nutrient solution, a shortness of breath occurs due to bulging of pores (lenticel). easy to do.

In addition, the method of preventing over-supply by reducing the amount of water supplied by lengthening the injection interval of the nutrient solution supplied to prevent the hypertrophy of the above-mentioned symptom of hypertrophy and the rot disease that occurs during harvesting and harvesting, and the hole on the side of the cultivation bed In the late stage of the growth of seed potatoes, the seed potato seedlings were switched from nutrient growth stages to reproductive growth stages when the seed potato seedlings were planted and cultivated in the cultivation tank that made the light inlet. There is a method of improving the physiological resistance of tubers by heating them to form chlorophyll and solanine in the well-being and tuber epidermis.

As described above, the cultivation method of lengthening the spray interval of the nutrient solution supplied has a problem that the temperature of the root zone of the seed potato seedlings in the cultivation bed changes rapidly depending on the outside environment and the seed potato seedlings are forged according to the difference in the idle width of the supplied nutrient solution.

In addition, a method of using a cultivation bed that provides light to the root zone of seed potato seedlings by drilling holes in the side of the cultivation bed is that the environment of the root zone formed by a specific heat having a constant temperature flows out through the light supply port at the side of the cold and warm air. As a result, it is difficult to create an optimal root zone environment maintenance.

In addition, the grower opens the top of the bed about 10 to 15 cm in the late stage of the growth of seed potatoes, and the cultivation method that exposes the indirect mountain mines to the welfare and tubers of the root zone directly exposes the root zone to the rapidly changing outdoor environment. Root hairs from the dry atmosphere of the house may be damaged and dried, and the specific heat of the nutrient solution with constant temperature supplied to the root zone is volatilized into the air. At the time of reaching the peak of direct sunlight and temperature (11: 00 ~ 16: 00), the root zone is elevated to a high temperature such as the atmosphere, and the optimal root zone environment required by the growers and the preventive measures taken by the high temperature damage of the root zone is required. Difficult to control

And. By providing the influx of pests that transfer virus diseases in the open bed root zone and the shelter of pests, it is difficult to control by drugs concerned about the damage of the root zone, which causes excessive burden and stress on growers.

In addition, repeated manual work by the grower to open and close the top of the planting bed to manage the temperature environment of the root zone, which rises due to the daytime atmospheric temperature, is cumbersome and requires a lot of labor. As the temperature and humidity are severely affected, the aging progresses rapidly due to the destruction of hair roots or damage to seed potatoes, which has a disadvantage in that the yield is low and the ups and downs are severe.

Thus, the present invention was devised to solve the above problems, by flowing a nutrient solution with a constant specific heat (cold and warm) sprayed regularly to the root zone of the seed potato seedlings in the bed at a certain level as nutrient solution flow bone on the bed bottom By maintaining the temperature of the root zone in the bed constant with the specific heat of the nutrient solution flowing through the rapidly changing root zone environment due to the supply frequency of the nutrient solution, the amount of liquid supply, and the change in the outside temperature, the optimum root zone environment required by the grower is established. The present invention relates to a cultivation bed suitable for a nutrient cultivation method for growing seed potatoes by cultivating seed potato seedlings. Particularly, seed seedlings in cultivation are converted from nutrient growing stages to reproductive growth stages, and are caused by excessive moisture sprayed after spraying seed potatoes. Others include nausea disease and rot disease affecting the plant stem hypertrophy and harvesting season which are physiological disorders to do The amount of light improved by the above-mentioned disease-free quality by irradiating diffused light into the double-sided window of cultivation bed on the side of the cultivation bed without affecting the bad environment It can be harvested in large quantities repeatedly so that the burden of quality improvement on the quality of the produced seed potatoes during the harvesting period is eliminated and the labor required for root control is eliminated.
