Example Embodiment
[0020] Example 1
[0021] (1) Preparation of micronutrient elements: take urea, superphosphate and plant ash according to the mass ratio of N, P, K to 3:1:1 and mix them for use;
[0022] (2) Cow dung dehydration: add fresh cow dung to cow urine, stir to obtain diluted cow dung liquid, squeeze and dehydrate by cow dung wet and dry separator, and then centrifuge and filter to obtain solid dry cow dung for use. The moisture content of solid dry cow dung is 40%-55%.
[0023] (3) Preparation of earthworm breeding base material: take 20kg of solid dry cow dung prepared in step (2), add 60g of micronutrient elements prepared in step (1) and 20g of earthworm bait (using okara), and mix well;
[0024] (4) Earthworm bioengineering transformation: Take the earthworm breeding base material prepared in step (3), and pave it in strips in a greenhouse, with a paving height of 15-20cm, a width of 5-10cm, and 4,000 earthworms per square meter. , Replace the earthworm breeding base material every 30 ...

[0034] Example 3
[0035] (1) Preparation of micronutrient elements: take urea, superphosphate and plant ash according to the mass ratio of N, P, K to 3:1:1 and mix them for use;
[0036] (2) Cow dung dehydration: add fresh cow dung to cow urine, stir to obtain diluted cow dung liquid, squeeze and dehydrate by cow dung wet and dry separator, and then centrifuge and filter to obtain solid dry cow dung for use. The moisture content of solid dry cow dung is 40%-55%.
[0037] (3) Preparation of earthworm breeding base material: take 20kg of solid dry cow dung prepared in step (2), add 120g of micronutrient elements prepared in step (1) and 20g of earthworm bait (using okara) and mix well;
[0038] (4) Earthworm bioengineering transformation: Take the earthworm breeding base material prepared in step (3), and pave it in strips in a greenhouse, with a paving height of 15-20cm, a width of 5-10cm, and 4,000 earthworms per square meter. , Replace the earthworm breeding base material every 30 ...
