Problems solved by technology

[0002] my country's annual straw production reaches 1 billion tons, but the utilization rate of straw is not high, and the technical level of the utilization method is low, and even the phenomenon of straw burning still exists, resulting in a certain waste of resources and environmental pollution
There are some technologies that use straw, wheat straw, branches, etc. to make hollow bricks and wall interior panels; liquefy straw, wheat straw, and corn stalks to make them regenerated into liquefied gas; produce silage through anaerobic microorganisms; Biomass solid waste is crushed and buried in the soil, but high energy consumption, low utilization rate, long digestion cycle, and perishability restrict the utilization of biomass solid waste

Embodiment 1

[0025] The invention discloses a method for cultivating earthworms by composting cow dung and straw, using fresh cow dung and straw as raw materials, mixing the fresh cow dung and straw in a weight ratio of 40:60, adding the mixed fermentation bacteria liquid to the mixed fermentation substrate, and mixing and fermenting The amount of bacterial liquid added is 5% of the weight of the fermented material. After mixing evenly, add water to adjust the moisture content of the fermented material to 60%, and then carry out composting fermentation. In the initial stage of fermentation, turn the compost once a day and keep the humidity above 40%. After rising to 60-70°C, maintain the temperature and ferment for another 4 days, keep the humidity, and turn the pile once a day. When the temperature drops to about 30°C, add earthworms to the mixed fermentation material, and the addition amount is 1 per cubic meter of fermentation material. 15,000 earthworms, and keep the humidity above 50%....

Embodiment 2

[0027] The invention discloses a method for cultivating earthworms by composting cow dung and straw, using dry cow dung and straw as raw materials, mixing dry cow dung and straw in a weight ratio of 35:65, adding the mixed fermentation bacteria liquid to the mixed fermentation substrate, and mixing and fermenting The amount of bacterial liquid added is 7% of the weight of the fermented material. After mixing evenly, add water to adjust the moisture content of the fermented material to 60%, and then carry out composting fermentation. In the early stage of fermentation, turn the compost once a day and keep the humidity above 50%. After rising to 60-70°C, keep the temperature and ferment for another 5 days, keep the humidity, and turn the pile once a day. When the temperature drops to about 30°C, add earthworms to the mixed fermentation material, and the addition amount is 1 cubic meter of fermentation material 18,000 earthworms, and keep the humidity above 50%. Add the compost fe...

Abstract

The invention relates to a method of earthworm cultivation through cow dung straw compost. Cow dung and straws are used as raw materials, the mixed materials of the cow dung and the straws are evenly mixed with mixed zymophyte liquid and then are watered and fermented until the temperature reaches 60 DEG C to 70 DEG C, and then fermentation is carried out for at least 3-5 days at the temperature. When the temperature goes down to 25 DEG C to 30 DEG C, earthworms are put into the fermentation materials, and according to consumption speed of nutriment in the cultivation process, fermentation products are added, a certain amount of earthworm cast is taken out, and the earthworms can be collected and harvested after maturing. The method can obviously improve growth speed and egg laying amount of the earthworms, and yield of the earthworms is improved.

Description

technical field [0001] The invention relates to a method for cultivating earthworms, in particular to a method for cultivating earthworms by composting cow dung and straw. Background technique [0002] my country's annual straw production reaches 1 billion tons, but the utilization rate of straw is not high, and the technical level of the utilization method is low, and even the phenomenon of straw burning still exists, resulting in a certain waste of resources and environmental pollution. There are some technologies that use straw, wheat straw, branches, etc. to make hollow bricks and wall interior panels; liquefy straw, wheat straw, and corn stalks to make them regenerated into liquefied gas; produce silage through anaerobic microorganisms; Biomass solid waste is crushed and buried in the soil, but high energy consumption, low utilization rate, long digestion cycle, and perishability restrict the utilization of biomass solid waste. [0003] With the continuous expansion of...
