Seedling growing method of pollution-free sweet potato seedlings

Abstract

The invention discloses a seedling growing method of pollution-free sweet potato seedlings. The seedling growing method of the pollution-free sweet potato seedlings comprises the steps of acceleratinggermination, building a seedbed, arranging seeds and growing seedlings, managing the seedbed, expanding reproduction and the like, so that the seed sweet potatoes are sown in advance, the seedling growing period is shortened, the survival rate of the sweet potato seedlings is increased, the disease resistance of the sweet potato seedlings is improved, pollution is avoided, a large amount of vegetative propagation is conducted to reduce the seedling growing cost, and the requirement on the sweet potato seedlings in product is met; furthermore, the sweet potato seedling transplanting survival rate is high, the sweet potato block is large and the economic benefit is significant.

Description

technical field [0001] The invention relates to the technical field of crop cultivation, in particular to a method for raising seedlings of pollution-free sweet potato seedlings. Background technique [0002] Sweet potato, also known as sweet potato, sweet potato, sweet potato, sweet potato, etc., people in different regions call it differently. People in Shandong call it sweet potato, people in Sichuan call it sweet potato, people in Beijing call it sweet potato, and people in Fujian call it sweet potato. [0003] There are many varieties of sweet potatoes, and the shapes are spindle, cylinder, ellipse, and spherical; the skin color is white, light yellow, red, yellow, and purple; the flesh color is yellow, apricot yellow, and purple. Usually mainly produce tubers or leaves. The tubers are formed by secondary hypertrophy of adventitious roots, which are longer than 25cm deep in the topsoil. Each plant can produce several tubers. Sweet potatoes are rich in sugar, protein, ...

Problems solved by technology

[0004] In the traditional sweet potato planting methods, hotbed planting is adopted, and a cultivation pool is generally set in the cultivation room, and then sweet potato seeds are planted on the land where farmyard manure is topdressed or wheat straw is piled up in the cultivation pool. The cultivation quantity of this cultivation method is limited, and The breeding speed is slow and only suitable for small-scale planting. The breeding temperature is not easy to control. If the temperature is too high, it will easily burn the sweet potato seeds. If the temperature is too low, the breeding speed is slow, and the breeding effect is very unsatisfactory, and it may also cause production reduction due to virus accumulation.
