Problems solved by technology

[0002] The current technology is mainly aimed at the nutrient solution or device for the production of the original seed by aeroponic cultivation of small-scale greenhouse potatoes and the corresponding cultivation methods, and there is no effective method for proper management of production and storage. The problems of low survival rate, occurrence of diseases during production, excessive growth of virus-free seedlings and high rate of rotten potatoes after tuber harvesting have not been resolved.
Sixth, there is no prevention of diseases in the potato production process, which may lead to the outbreak of a certain disease and cause production failure
Seventh, the growth of potatoes is not controlled during the peak growth period, which will lead to excessive physiological growth of potatoes, reduce the tuber formation rate, and increase the probability of disease occurrence
Eighth, the post-harvest potatoes are stored in storage without chemical treatment, which may lead to large-scale rotten potatoes

Embodiment 1

[0084] Location: Net Room of Crop Institute of Sichuan Academy of Agricultural Sciences, with an area of ​​about 2000m 2 .

Embodiment approach

[0086] 1. Screen high-quality potatoes, remove viruses from their shoot tips, and start tissue culture and rapid propagation after virus detection and field experiments (elimination of mutant strains).

[0087] 2. After 25 days of tissue culture seedlings, start hydroponic strong seedlings (hydroponic seedlings are cultivated at a density of 2500 seedlings per square meter according to the plant spacing and row spacing of 2cm, and the foam board with holes needs to be prepared in advance, and the hole spacing on the board is 2cm, hole diameter is 5mm), after 15 days, cut 10-15cm long potato seedlings for planting, and the scissors used for cutting seedlings should be sterilized with 75% alcohol. All links in the middle should pay attention to the disinfection of the environment, operators and tools used.

[0088]3. The greenhouse and the box of aeroponic potatoes should be cleaned half a month before planting, and the box of aeroponic potatoes should be cleaned with 40% forma...

Embodiment 2

[0103] Location: CIP Sichuan Academy of Agricultural Sciences High-efficiency Production Base of Virus-free Seed Potatoes, with an area of ​​about 5,000㎡

[0104] 1. Screen high-quality potatoes for virus-free, and start tissue culture and rapid propagation after virus detection and elimination of mutant strains.

[0105] 2. After 30 days of tissue culture seedlings, start hydroponic cultivation. After 15 days, cut potato seedlings with a length of 10-15 cm for planting. The scissors used for cutting seedlings should be sterilized with 75% alcohol. All links in the middle should pay attention to the disinfection of the environment, operators and tools used.

[0106] 3. The greenhouse and the box of aeroponic potatoes should be cleaned before planting seedlings. The box of aeroponic potatoes should be cleaned with 40% formalin 200 times solution, 800 times potassium permanganate solution or 500 times carbendazim, etc. Carry out thorough disinfection and cleaning 2 to 3 times,...

Abstract

The invention belongs to the field of agricultural technology, and particularly relates to a nutrient solution and a method for producing potato breeder seeds by aeroponics. The formula of the nutrient solution provided by the invention mainly comprises the elements such as nitrogen, phosphorus and potassium; and in the faculty of agricultural sciences, the formula is improved based on the formula of a potato MS culture solution, and the concentration ratio of nitrogen to phosphorus to potassium is properly adjusted according to different growth periods of potatoes. The method for producing potato breeder seeds by aeroponics provided by the invention starts from each link of large-scale production of potato breeder seeds, and comprises detailed operation measures in terms of nutrient solution, strong seedlings of tissue culture seedlings, disinfection of an aeroponics device, seedling loading and drawing, pest control, treatment and storage after potato harvesting and the like so as to solve the problems such as low survival rate of aeroponics seedlings, low single-strain potato yield, damage caused by diseases and insects and low output of breeder seeds caused by excessive growth of aeroponics seedlings due to a bad aeroponics management method in aeroponics production.
