Problems solved by technology

[0002] In the traditional sweet potato planting methods, hotbed planting is adopted, and a cultivation pool is generally set up in the cultivation room, and then sweet potato seeds are planted on the land where farmyard manure 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, only suitable for small-scale planting, the breeding temperature is not easy to control, the sweet potato seeds are easily burned if the temperature is too high, the breeding speed is too low, and the breeding effect is very unsatisfactory

Abstract

The invention belongs to the technical field of sweet potato seedling cultivation methods and particularly relates to a sweet potato seedling batch production method. According to the sweet potato seedling cultivation method, breeding speed is high, large-scale production can be well achieved, and the emergence rate is high. According to the technical scheme, (1) the soil for sweet potato seedlingcultivation is subjected to deep ploughing in autumn and winter; (2) in next spring, farmyard manure is applied in the soil, the soil is leveled, and bed forming is carried out; (3) a plurality of geothermy lines are arranged in each bed in parallel; (4) summer sweet potatoes are selected for seedling cultivation, in mid-March, sweet potatoes are planted in the soil, and double films are arrangedin a covering mode; (5) high-temperature seedling maturation acceleration is carried out; (6) normal-temperature seedling cultivation is carried out; (7) low-temperature seedling exercising is carried out; (8) and seedling airing is carried out. According to the method, sweet potato seedling cultivation can be carried out in large area, cultivated sweet potato seedlings are very strong, and yieldis high.

Description

technical field [0001] The invention belongs to the technical field of cultivation methods of sweet potato seedlings, and in particular relates to a batch production method of sweet potato seedlings. Background technique [0002] 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, only suitable for small-scale planting, and the breeding temperature is not easy to control. If the temperature is too high, it is easy to burn the sweet potato seeds. If the temperature is too low, the breeding speed is slow, and the breeding effect is very unsatisfactory. Contents of the invention [0003] The invention overcomes the shortcomings of the prior art, and the t...
