Description

[0001] The present invention relates to a recirculating drainage hydraulic apparatus for producing seed potatoes and a cultivation method using the same,

In particular, the present invention relates to a method for cultivating a seed potato by combining a circulation type salmon hydraulic device with a spray process.

Generally, the cultivation system of crops can be roughly classified into no-crop cultivation and plant cultivation. Facility cultivation is growing crops using glass greenhouses or vinyl houses. Salt accumulation due to excessive use of chemical fertilizers is an obstacle to crop growth. In addition, it is difficult to expect a good harvest in non-cultivation or in plant cultivation if crops are continuously grown in the same soil. Accordingly, hydroponic cultivation for cultivating crops with a culture solution has been widely performed.

Hydroponic cultivation can regulate the growth rate of plants by feeding the crops with cultures in which essential nutrients are dissolved, without cultivating the crops in the soil.

These hydroponics are aeroponics, deep-water culture, aerohydroponics, substrate culture, etc., and the most commonly used seeds are cultivated seeds in Korea . In some cases, the diameter of the pipe is used.

The spray gun is a method in which the roots of the potatoes are absorbed in the air while being suspended in the air in the bed. Especially, it is widely used for seed potatoes because it is easy to supply oxygen to roots, stolons, tubers and tubers. However, potato roots are exposed to air, causing power failure or blockage of the nozzle. If the culture medium is not supplied for a long time, the plant may be worn out due to lack of water, or it may dry out.

When seed potatoes are cultivated in the saliva (non-circulating), the size of the tubers grows in the water, and the pores on the surface of the tubers bloom and the quality deteriorates.

In addition, the culture medium is used in a medium such as pearlite, coco peat, honey and rocky surface (solid material capable of supporting the root of the plant such as soil) alone or in combination, Lt; / RTI >

Therefore, there is a need for a cultivation technique that can increase tuber production while ensuring the stability of seed potato production in hydroponic cultivation.

In addition, the pH of the fresh water solution means a method of regulating the water level in the bed 120 to fill the culture solution. Particularly, the present invention uses a circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type circulation type.

Here, the term "tuber" means a carbohydrate storage organ made by photosynthesis, which means that the end of the stolon is swollen. In the present invention, the term "tuber" means a seed potato.

1 and 2, the present invention relates to a circulation type washing and watering apparatus 100, which comprises a formal panel (not shown) in which at least one seed potato graft 10 having a planting mouth can be transferred, 110); A bed 120 in which a space for accommodating the formal panel 110 is formed and for pouring the culture liquid required for the seed potato seedlings 10 to be planted in the formal panel 110; A feed pipe 121 connected to the circulation pump 200 for circulating the culture liquid into the bed 120 and supplying the culture liquid to the bed 120; And a drain pipe (122) for collecting the culture liquid circulated through the bed (120); And a drain port spaced apart from a lower end of the bed 120 by a predetermined distance to maintain the level of the culture liquid in the bed 120 is formed in the drainage pipe 122, And is dipped in the culture solution.

More specifically, the circulation type washing water hydraulic system 100 of the present invention is a partial modification of the dispenser bed 120. As shown in Fig. 1, the circulating type washing water hydraulic system 100 circulates in a cultivation tank filled with the culture solution, So that some of the potato roots and the underground stem absorb the nutrients and moisture while being immersed in the culture medium, and do not immerse in the culture medium, and the roots exposed to the air act to absorb oxygen.

At this time, the level of the culture liquid to be filled in the bed 120 can be controlled by connecting the water level control pipe 123 to the water discharge pipe 122 of the circulation type liquid water hydraulic system 100. The water level control pipe 123 can be connected to the water outlet pipe 122 inside the bed 120 and can be easily separated if necessary.

In addition, a filter for filtering out impurities such as plant root residues contained in the circulating culture liquid may be disposed at one end of the water level control pipe 123. In addition, the saline water hydraulic system 100 may include a light source unit 300 for irradiating light to the seed graft.

The method of cultivating seeds according to the present invention comprises: a first spraying step of seeding a seedling seedling on a formal panel (110) and cultivating the sprayed seedlings in a spraying tube; The method of claim 1, wherein the circulation type hydraulic fluid hydraulic device (100) according to claim 1 is replaced with a circulating hydraulic fluid hydraulic device (100). And a second spraying step in which the suspension is cultivated in an aerosol after the dipping step; .

At this time, the first slurry phase may be cultivated for 40 to 50 days, the broth liquid phase may be cultivated for 14 to 42 days, and the second cultivated phase may be cultivated for 20 to 40 days. In addition, the depth of the culture liquid may be maintained at 5 cm to 20 cm at the pH of the saline solution.

Particularly, the respective periods in the first spraying step, the salting water step and the second spraying step may be varied depending on the kinds of the potatoes to be cultivated. When the cultivation period is less than 40 days in the first spraying step, The formation efficiency is lowered, and in the case of exceeding 50 days, the gas barrier efficiency can be lowered.

In addition, as in the first fractionation step, when the seedling cultivation period is less than 14 days, the efficiency of tuber formation may be lowered. In case of exceeding 42 days, in the second fractionation step Because the tuber enlargement period is shortened, the bulk guard efficiency can be lowered. In addition, the second spraying phase may be 20 to 40 days, which may vary depending on the duration of the first spraying phase and the pond water phase.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the following examples. However, the following examples are intended to illustrate the contents of the present invention, but the scope of the present invention is not limited to the following examples. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art.

< Example >

Example  1. Circulation type Dipping water  Cultivation preparation

In vitro plants of the seeds produced by the tissue culture technique in the example of the present invention were transferred to the formal panel 110 of the analgesic bed 120 and planted. After about 3 weeks after planting the seed potato (10), the roots grew to reach the bottom of the bed (120). From this time, it was examined to convert the spray cultivation system into the soaking system. That is, after the formulation, the water was changed into the circulating liquid water solution from 25 days, 39 days, 53 days, and 67 days, and the results were compared in the following examples.

Particularly, in this embodiment, a culture solution for potato only was used.

In addition, the circulation type drinking water hydraulic system 100 uses the apparatus shown in Figs. 1 and 2.

More specifically, the supply pipe 121 and the water discharge pipe 122 are installed so that the culture liquid is supplied from one side of the bed in order to keep the culture liquid filled in the bed 120, the opposite side is filled with a predetermined amount or more, Respectively. In addition, the supply pipe 121 is connected to the timer to adjust the supply interval of the culture liquid.

Example  2. Dipping water  By turnover With tuber count  Size distribution

This example compares the size distribution and the size distribution of the tuber diameter by the time of dialysis in the distillate diameter and is shown in Table 1. The cultivars at this time were Sui and Self.

kind When the pond water shifts Tuber count (/ week) Tuberous (/ week) Average tuber > 1 g > 5g > 1 g > 5g > 1 g > 5g Sumi 25th 25.2 12.7 237 205 9.7 16.5 39 days 27.8 12.8 205 155 7.4 12.1 53 days 34.0 16.8 207 159 6.1 9.5 67 days 32.5 18.8 305 265 9.5 14.0 Self-help 25th 21.8 7.9 160 125 7.4 16.1 39 days 22.1 12.6 199 171 9.0 13.5 53 days 29.3 8.8 163 113 5.6 12.7 67 days 29.8 14.7 197 157 6.7 10.8

In this example, the tuber number tended to increase as the transition time to the pond water diameter became slower. The number of tubers was not increased by the conversion to the pond water on the 39th day after the transfer to the bed, but the conversion of the tubers to the pond diameter on the 53rd day (early tuber formation - . Here, it was found that the period of transition to the circulating saline solution by the spraying method was suitable for the tuber-forming period or the beginning of the pulverizer.

Example  3. Dipping water ( DFT ) Potato quantity and size distribution by treatment period

In this example, the tuber yield and the size distribution by the duration of the salting water hydroprocessing are compared and an average is shown for each year. The varieties of seed potatoes were Sui, Fine, Haengryeong, and Sajeong.

kind When the pond water shifts Tuber count (/ week) Tuberous (/ week) Average tuber > 1 g > 5g > 1 g > 5g > 1 g > 5g Sumi 0 20.3 12.2 277 256 13.8 20.6 2 33.4 16.3 295 254 9.0 15.8 4 36.7 16.7 373 325 11.3 19.5 6 33.7 16.6 334 289 10.3 18.4 delicate 0 12.3 10.1 268 263 21.1 24.8 2 26.4 13.6 346 318 14.8 23.3 4 29.4 12.6 322 278 13.6 21.9 6 44.5 16.1 346 273 9.5 18.6 Ha 0 9.5 6.6 169 161 17.5 24.0 2 15.3 8.0 223 208 15.6 25.7 4 20.5 9.4 232 206 12.9 22.2 6 17.7 9.8 239 220 13.3 22.1 Self-help 0 13.3 9.6 213 204 15.9 21.1 2 18.1 10.1 214 199 12.0 19.7 4 23.8 11.6 234 207 11.1 18.0 6 21.4 10.9 226 202 11.1 20.4

Table 2 shows the potato quantity and size distribution according to the duration of DFT treatment. Here, the term "0" refers to the cultivation of seeds only in the minute size, without switching to the pond water diameter. In the present example, two weeks of the hydroponics treatment period means that the seedlings were cultivated in a hydroponic system for 14 days after the seedlings were grown to the tuber forming period by the spraying method, and the remaining period was cultivated again by the spraying method .

As a result of comparing the tuber counts according to the duration of the hydroponics treatment in this example, it was confirmed that the number of tubers increased when the submersibles were cultivated for 2 weeks, for 2 weeks, and for 2 to 6 weeks, respectively. In other words, the increase of tuber number according to the period of cultivation in the pond hydroponics varied according to the cultivars. In addition, it was confirmed that the tuber number was increased by combining spraying and ponding hydroponics rather than cultivating only the spraying medium without using the ponding watering method.

In addition, when the paddy liquor system was introduced, it was found that the average tuber size was reduced compared with the cultivated tuber, but this was because the tuber number was increased when cultivated in the paddy liquor system.

In this example, the seedling production was found to be high due to the increase in the number of tubers when the spinach seedling method was used at the early stage of seedling cultivation in the hydroponic cultivation of the seeds, there was.

Example  4. Dipping water ( DFT ) By culture depth Tuber yield and  Size distribution

In this example, the tuber yield and size distribution were compared by the depth of the culture solution of the saline solution type. More specifically, the level of the culture liquid to be filled in the cultivation tank was adjusted by connecting a water level control tube to the drainage pipe in the cultivation tank, and the depth was adjusted to 5, 10, and 20 cm and compared with that of the culture solution . The seed tubers were transferred to the bed, and the tubers, tubers and average tubers were compared between 95 and 100 days after planting. The varieties were Sui, Fine, Haengryeong, and Soul.

As shown in Table 3, in the case of the puddle water-hydraulic system, the number of tubers was increased as compared with that of the spray, so that the depth of the culture was about 5 to 20 cm.

FIG. 3 is a photograph showing the number and size of potatoes according to the culture depth of a superied cultivar in this embodiment. As can be seen from the naked eye, the number of tubers increased when they were converted to circulating saline solution than when using only the spraying method. As shown in FIG. 3, the number of tubers was significantly larger in the submerged cultivars than in the tubular cultivars when the culture solution of the puddle of water was 20 cm deep.
