Embodiment 1
[0112] 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.
[0113] Dig ditches and ridges in the facility farmland, and the soil humidity in the facility farmland is 50%. The distance between the ridges is 4m, and 4 inter-ridge ditches are opened per mu. The depth of the inter-ridge ditches is 60cm, and the width of the inter-ridge ditches 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.
[0114] Put 1.2kg earthworm seedlings into each net bag again, add 0.55L water again, allow earthworms to moisten and facilitate it to drill into the soil quickly, then cover th...
Embodiment 2
[0117] 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.
[0118] Ditching and ridges are made in the farmland of the facility greenhouse, and the humidity of the soil in the farmland is 45%. The distance between the 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 0.7m. 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.
[0119] Put 1.1kg earthworm seedlings into each mesh bag again, add 0.50L water again, let the earthworms moisten and facilitate it to drill into the ...
Embodiment 3
[0124] The earthworms obtained in Example 1 are classified, weighed, and the interval ratio after collection, and it is found that each earthworm with more than 6 grams accounts for 14%, and each earthworm with 5-6 grams accounts for 23%, and each 4-5 grams Earthworms accounted for 37%, each 3-4 grams of earthworms accounted for 16%, each 2-3 grams of earthworms accounted for 10%, the specific results are shown in Table 1. Among them, more than 90% meet the harvesting requirement of medicinal earthworms ≥ 2.5 g / piece.
