Embodiment 1

[0021] (1) Preparation of micronutrient elements: Mix urea, superphosphate and plant ash according to the mass ratio of N, P and K at 3:1:1, and set aside;

[0022] (2) Cow dung dehydration: Add fresh cow dung to cow urine, stir to obtain diluted cow dung liquid, squeeze and dehydrate through a cow dung dry-wet separator, and then centrifuge, filter and separate to obtain solid dry cow dung for use. The moisture content of solid dry cow dung is 40%-55%.

[0023] (3) Preparation of base material for earthworm breeding: take 20 kg of solid dry cow dung prepared in step (2), add 60 g of micronutrient elements prepared in step (1) and 20 g of earthworm bait (using bean dregs), and mix evenly;

[0024] (4) Earthworm bioengineering transformation: take the earthworm breeding base material prepared in step (3), and spread it in strips in the greenhouse with a height of 15-20cm and a width of 5-10cm, and put 4,000 earthworms per square meter , the base material for earthworm culture ...

Abstract

The invention discloses a method for producing a rice seedling cultivation matrix through earthworm conversion of cow dung; the method comprises the steps: after the cow dung is dewatered, adding nitrogen, phosphorus and potassium and earthworm baits, blending to prepare an earthworm culture base material, carrying out earthworm culture, converting into vermicompost, and then producing the rice seedling cultivation matrix with the vermicompost. The conversion process of the cow dung is simple and green and environmentally friendly; the earthworm culture base material is prepared by using the cow dung, the reproductive rate of the earthworms is increased, besides, continuous pile-turning in a process of fermentation preparation of an organic fertilizer is avoided, and manpower is saved; the vermicompost formed after conversion is used for preparation of the rice seedling cultivation matrix, and can effectively improve the rice cultivation effect.

Description

technical field [0001] The invention relates to the reuse of cow dung, in particular to a method for using earthworms to transform cow dung to produce a substrate for raising rice seedlings. Background technique [0002] In the past two decades, the cattle industry has developed rapidly, but with the development of large-scale cattle farms, the associated manure has seriously affected its own sustainable development. The direct stacking of cow dung will pollute the surface and groundwater. This not only brings harm to the rural environment, but also seriously affects the environmental quality of the surrounding cities. [0003] The traditional use of cow dung is mostly drying to prepare fuel, directly fertilizing the field, or anaerobic fermentation to obtain biogas residue, biogas slurry and biogas. Drying to prepare fuel and anaerobic fermentation require equipment and occupy a large area. And directly fertilize the field, the smell is unpleasant and it is easy to pollu...
