Problems solved by technology

[0012] The second characteristic of aerosol cultivation to produce the original seed of virus-free potato / miniature potato is that the nutrients and water required by the plant are artificially configured by us, and artificially controlled by adjusting the spraying cycle. The advantage is that our control is more convenient, and the disadvantage is the nutrition and water supply. It has a certain rigidity, unlike soil or substrate cultivation, its nutrition is supplied by the soil or substrate, and it has a certain buffering property

Embodiment 1

[0085] In the greenhouse of the original seed breeding base of virus-free potatoes, 30 test-tube seedlings of Qinyu, which were cultivated and tested for virus-free, were used as materials. After the test-tube seedlings were planted in the fog culture box, they were sprayed with water on the first 1-3 days. The spraying cycle was: every Spray for 40s every 3 minutes; use HR nutrient solution on the 4th to 7th day, and the spray cycle is: spray for 40s every 3 minutes.

[0086] After the test-tube plantlets take root and survive the seedling stage, use HG nutrient solution according to the growth needs of the test-tube plantlets. The spraying method is: during the day (7:00-19:00) the spraying cycle is spraying every 10 minutes for 40 seconds, and at night (19:00-7:00) the spraying cycle is: spraying every 20 minutes for 40 seconds.

[0087] When the tubers begin to form, switch to HF nutrient solution according to the nutritional requirements of potatoes. The spraying method ...

Embodiment 2

[0091] In the greenhouse of the original seed breeding base of the virus-free potato, the test-tube seedling No. 1 of the virus-free Dashu was cultivated and tested as the material, and the test-tube seedling was sprayed with clean water on the first 1-3 days after it was planted in the fog cultivation box. The spraying cycle was: Spray for 40s every 3 minutes; use HR nutrient solution on the 4th to 7th day, and the spray cycle is: spray 40s every 3 minutes.

[0092] After the test-tube plantlets take root and survive the seedling stage, use HG nutrient solution according to the growth needs of the test-tube plantlets. The spraying method is: during the day (7:00-19:00) the spraying cycle is spraying every 10 minutes for 40 seconds, and at night (19:00-7:00) the spraying cycle is: spraying every 20 minutes for 40 seconds.

[0093] When the tubers begin to form, switch to HF nutrient solution according to the law of potato nutrient requirements. The spraying method is: during ...

Abstract

The invention discloses an aerial fog cultivation nutrient solution for a breeder's seed of a virus-free potato and an application method of the serial fog cultivation nutrient solution. The aerial fog cultivation nutrient solution mainly contains five nutrient solutions: an HR nutrient solution, an HG nutrient solution, an HF nutrient solution, an HE nutrient solution and an HH nutrient solution;the whole aerial fog cultivation process of test-tube seedlings of the virus-free potato is divided into five stages: a rooting stage, a seedling stage, a tuber formation stage, a tuber expansion stage and a harvesting stage; and different nutrient solution formulae are respectively set in different stage, and the nutrient solutions are sprayed according to different atomizing periods. The aerialfog cultivation nutrient solution has the advantages that the survival rate of the test-tube seedlings of the virus-free potato is remarkably increased, the growth of fog-cultivated plants of the potato is effectively promoted, the fog-cultivated fruiting number is increased, the single grain weight is increased, and the storage rotting rate of the fog-cultivated potato blocks is decreased.

Description

technical field [0001] The invention relates to the technical field of agricultural cultivation, in particular to a nutrient solution for aerosol cultivation of original seed of detoxified potato and an application method thereof. Background technique [0002] Aerosol cultivation means that the root system of the crop is suspended and grown in a closed, light-tight container (trough, box or bed), and the nutrient solution is formed into a mist through special equipment, and is sprayed intermittently on the root system of the crop to provide the nutrients needed for the growth of the crop. A soilless cultivation technique of water and nutrients. It is the best form of solving the water-air contradiction of the root system in all soilless cultivation techniques. [0003] Aerosol cultivation is a new type of cultivation mode to produce the original seed of virus-free potato, and its efficiency is dozens of times higher than that of substrate cultivation. This technology has c...
