Embodiment Construction

[0037] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific examples described here are only used to explain the present invention and are not intended to limit the present invention. .

[0038] The aerosol breeding method for cultivating small seed potatoes of virus-free potatoes comprises the following steps:

[0039] According to the characteristics and characteristics of the growth and development of aeroponic potatoes, it is divided into 6 growth stages; namely, the rooting stage of planting, the seedling stage, the seedling stage, the small potato formation stage, the small potato formation stage, the expansion and harvest stage, and the decline stage. According to the 6 growth and development stages, formulate 6 corresponding nutrient solution formulas, which are called six-six combinati...

Abstract

The invention relates to the technical field of soilless cultivation, and in particular to a cultivation method for breeding small seed potatoes of virus-free potatoes though areoponics. According tothe physiological basis of potato cultivation through aeroponic cultivation, the growth can be divided into six stages, and six formulas of suitable nutrient solutions are prepared according to the six growth stages; according to the method and technology involved in the invention, the requirements for external environment conditions of light, temperature, water, fertilizer and air at each growthstage of the potatoes obtained through the aeroponic cultivation are met, three latent traits of the potatoes of stem diversity, bud multiplicity and stem and leaf regeneration are sequentially induced into phenotypic fine traits, stolon promotion, tuber formation, potato pieces swelling and picking are continuous and ceaseless for 100 days or above for growth, 60 to 80 grains of qualified small seed potatoes with a yield of 10 g or above for a single plant are obtained, and the yield per mu of the aeroponic cultivation in a greenhouse is 450000 to 550000 grains; the production cost, storage resistance and preservation property of the potatoes obtained through the aeroponic cultivation are similar to or slightly lower than that of substrate potatoes, and the survival rate of seedlings andthe growth potential at a seedling stage are better than that of the substrate potatoes; the technological achievements of the invention achieve the purposes of the practical promotion and applicationof large-scale production.

Description

technical field [0001] The invention belongs to the technical field of soilless cultivation, and in particular relates to a cultivation method for aerosol breeding of virus-free potato seedlings. Background technique [0002] At present, there are mainly four methods for breeding virus-free potato seedlings in my country: soil cultivation, in which the potato virus-free seedlings are raised and then directly planted in the soil; soilless substrate cultivation, that is, vermiculite, peat, sand, perlite Soilless cultivation with other substances as substrates; container method, through improving the medium formula, inducing detoxified tissue culture seedlings to produce small aerial tubers under dark conditions; aerosol method, which is a new method of hydroponic cultivation, nutrient solution Small seed potatoes obtained by timed and quantitative atomization of potato roots grown under dark ambient conditions. [0003] The main advantages of the aerosol method are: the amount ...
