A kind of method for cultivating earthworms in an open-air environment
A breeding method and industrialized technology, applied in the field of agricultural breeding, can solve the problems of high mortality, separation from the growth environment, time-consuming and labor-intensive, etc., and achieve the effects of low earthworm escape rate, convenient harvesting and high purity.

Examples
Embodiment 1
[0110] 50kg of soil and 6kg of earthworm breeding material are rotted and stirred to prepare the mixture, watered and kept moist, so that the humidity of the soil is controlled at 65%, and packed into a mesh bag. The size of the mesh bag is 50cm*50cm*80cm, and the mesh size in the mesh bag is 50 mesh.
[0111]Ditching and ridges are made in the farmland in the open environment, the soil humidity in the farmland is 50%, and the mu area of the farmland is calculated as 42 meters long and 16 meters wide. The distance between adjacent ridges is 4m, and 4 inter-ridge furrows are opened per mu. The depth of the inter-ridge furrows is 60cm, and the width of the inter-ridge furrows is 0.65m. A mesh bag is placed in every meter of ditch between the ridges, the seal of the mesh bag is knotted, and the top of the mesh bag is exposed outside the ditch between the ridges and is 10 cm above the farmland level.
[0112] Put 1.2kg earthworm seedlings into each net bag again, add 0.55L wate...
Embodiment 2
[0115] 50kg of soil and 4.5kg of earthworm breeding material were rotted and stirred to prepare the mixture, watered and kept moist, so that the humidity of the soil was controlled at 60%, and packed into a mesh bag. The size of the mesh bag is 50cm*50cm*80cm, and the mesh size in the mesh bag is 60 mesh.
[0116] Ditching and ridges are made in the farmland in the open environment, the soil humidity in the farmland is 45%, and the mu area of the farmland is calculated as 42 meters in length and 16 meters in width. The distance between adjacent ridges is 4m, and 4 inter-ridge furrows are opened per mu. The depth of the inter-ridge furrows is 55cm, and the width of the inter-ridge furrows is 0.60m. A mesh bag is placed in every meter of ditch between the ridges, the seal of the mesh bag is knotted, and the top of the mesh bag is exposed outside the ditch between the ridges and is 10 cm above the farmland level.
[0117] Put 1.1kg earthworm seedlings into each mesh bag again,...
Embodiment 3
[0126] The earthworms obtained in Example 1 were classified, weighed, and the interval ratio after collection, and it was found that each earthworm with more than 6 grams accounted for 19%, and each earthworm with 5-6 grams accounted for 42%, and each 4-5 grams Earthworms accounted for 23%, each 3-4 grams of earthworms accounted for 10%, each 2-3 grams of earthworms accounted for 6%, the specific results are shown in Table 1. Among them, more than 94% meet the harvesting requirement of medicinal earthworms ≥ 2.5 grams per earthworm.
