Method for breeding big earthworms and planting crops in greenhouse
Technical Field
The invention belongs to the technical field of animal breeding, and particularly relates to a method for breeding big earthworms and planting crops in a greenhouse.
Background
With the rapid development of modern agriculture, a large number of various greenhouses are built and used for planting high-quality and out-of-season vegetables and various crops. In order to accelerate the improvement of soil fertility to increase the yield of crops, agricultural fertilizers are used in large quantities. After a long time, the organic matter of the soil in the greenhouse is lower, the granular structure of the soil is seriously damaged, and the hardening degree of the soil is higher. This condition is a catastrophic failure of the agricultural land. In order to change the development of the adverse condition, small red earthworms (such as Daping No. 2) are cultured on the ground surface in some places at present, and the excrement discharged by the small red earthworms is utilized to improve the fertility of the soil so as to achieve the aim of increasing the yield of crops. However, in this method, once red earthworms are bred, a certain amount of excrement is produced to improve the fertility of the soil, and at least 3 years or more is required. And after the land is planted for 2 to 3 years, the fertility of the soil can be improved by repeatedly adopting the method for breeding the red earthworms after the fertility is exhausted. The living activities of the red earthworms only stay in the soil with the surface layer of about 5 cm, so the method does not play any role in improving the fertility and the structure of the soil under the ground surface.
In the past, large earthworms are tried to be cultivated in a greenhouse, but the requirement on the survival condition is high because the large earthworms are used to the wild habit, and the environment formed by the existing greenhouse structure does not meet the survival condition of the large earthworms, so that the large earthworms die and cannot survive.
