Description

Method for mass production of virus-free seed potatoes using photo control and A culture container according to light control

The present invention relates to a method and a production cultivation facility for producing a large amount of high quality fine seed potatoes using the underground light environment in the production of seed potato (種薯; seed paper), more specifically in the production of seed nutrient solution method The present invention relates to a method of producing high quality seed potatoes by improving problems such as tuber hypertrophy of tubers, deterioration of shelf life after harvesting, and deterioration of seed quality. By supplying light to the basement of the bed during growth, it is possible to separate the cultivation of welfare and roots by using the welfare and the physiological differences of roots to prevent the reduction of tuber hypertrophy of the tuber, the deterioration of shelf life after harvesting, and the good germination rate. The present invention relates to a high quality seed potato mass production method and a cultivation bed.

Potatoes belong to the eggplant family, and the crop is mainly for nutritional propagation by tubers. In the process of nutritional propagation, degeneration due to viral infection occurs, resulting in a decrease in yield. In order to prevent this, after collecting the growth point where there is little virus infection density in the plant, go through the tissue culture propagation step, and use the stem and tuber after the cultivation step 6-8 times in the soil and soil, and then use it as a seed. It is done. In the case of higher-level seeding by top soil and soil cultivation, the unit yield is low and it is necessary to go through several stages of seeding. In order to shorten this, the method of producing small tubers by nutrient solution cultivation with high production quantity is partly used. Comparison of the characteristics of the basic seed production method is shown in Table 1 below.

As a conventional technique for seed production, Korean Patent Publication No. 1996-36908 (mass production method of seed potatoes by nutrient solution) obtains seedling seedlings by tissue culture method and hardens them to obtain disease-free nutrient solution seedlings and disease-free nutrient solution seedlings. It is a method of promoting tuber formation by adding growth regulator to low concentration in potato tuber forming machine by cultivating while supplying oxygen by bubble generator in water to generate roots and discontinuously supplying to the bottom of nutrient solution bed. It is difficult to obtain seed potatoes of uniform size due to mixed roots and roots, and bulging tubers (lenticel) (hypertrophy), so that the quality of seed potatoes is lowered, the shelf life after harvesting, and the germination rate after seeding are lowered. In order to minimize this problem, some researches have been conducted on the method of producing seed potatoes by nutrient cultivation, such as spraying and supplying nutrient solution, and controlling the amount of nutrient supply. I can't. When the nutrient solution is excessively supplied by the method of spray supply of the nutrient solution, the hypertrophy phenomenon still occurs when tubers touch the nutrient solution flowing to the bottom of the bed (May 1999, the result of the test of Heidei Co., Ltd.).
