Method for cultivating big earthworms and planting crops in greenhouse

Abstract

The invention relates to a method for cultivating big earthworms and planting crops in a greenhouse and application. The method adopts a greenhouse cultivation mode to cultivate big earthworms and plant crops, animal manure, vegetable residual leaves and crop straw crushed materials are uniformly stirred and fermented to be used as earthworm feed, earthworm seedlings are put into ridge soil according to 30 kg per mu of field, the earthworms are put for 7-10 days, and then vegetables or crops are planted; in spring, summer and autumn, a plastic cloth or glass window on the top layer of the greenhouse is closed in the daytime and opened at night, and the purposes of allowing dew to enter the soil surface in the greenhouse and cooling are achieved; the top layer of the greenhouse is covered with a sun-shading cloth when the air temperature reaches 30 DEG C or above in sunny days in summer; and the earthworms are harvested when the local air temperature is 20-25 DEG C in spring or autumn.According to the method, it is ensured that the big earthworms can survive in the greenhouse, high-yield and high-production-efficiency large-batch cultivating of the earthworms is achieved, the soilquality of the greenhouse is improved, and the yield of vegetables or crops is increased.

Description

technical field [0001] The invention belongs to the technical field of animal breeding, and in particular relates to a method for breeding large earthworms and planting crops in a greenhouse. Background technique [0002] With the rapid development of modern agriculture, a large number of various types of greenhouses have been established for the cultivation of high-quality and off-season vegetables and various crops. In order to accelerate the improvement of soil fertility to increase the yield of crops, agricultural chemical fertilizers are used in large quantities. If things go on like this for a long time, the soil organic matter in the greenhouse is getting lower and lower, the aggregate structure of the soil is severely damaged, and the degree of compaction of the soil becomes higher and higher. This situation is catastrophic for agricultural land. For changing the development of this unfavorable situation, some places adopt at present to breed little red earthworms ...

Problems solved by technology

Second, the living activities of red earthworms only stay in the soil about 5 cm above the soil surface, so this method does not have any effect on improving the fertility and structure of the soil below the surface

[0003] In the past, some people tried to breed large earthworms in greenhouses, but because large earthworms are accustomed to wild habits, they have relatively high requirements for living conditions. Survive
