Method for improving degradation and aerobic composting of cow dung with earthworm

Abstract

The invention relates to a method for improving degradation and aerobic composting of cow dung with earthworms and belongs to the field of agricultural techniques. The invention is characterized in that: the cow dung with a water content of 50% to 70% is collected after high-temperature fermentation stage and fed into a modified composting pond; the body of the composting pond is full of cow dung and the height of the cow dung pile is 0.4 m; 8000 to 15000 Daping No.2 earthworms are inoculated into the pond, and rice straws are coated on the surface of the pile after all the earthworms go into the pile and watered thoroughly; pile samples are collected for pH measurement during the culture process, and the range of pH suitable for earthworm growth is 6.5 to 8.5; after the inoculation is completed, the water is applied for 2 to 3 times every day to wet the rice straw coating, and the water content is controlled about 60% to about 70%; chickens are raised in chicken cages after the earthworms reproduce to a certain breeding amount; the reproduced earthworms are taken out of the pond and dried and pulverized to make fish feeds; the manures of the chickens and the manures of the earthworms are directly fed into the composting pond for composting, to increase the composting effect; and the reproduced earthworms are directly used to feed the chickens. Therefore, a complete agricultural ecological chain is formed.

Description

technical field

[0001] The invention relates to an aerobic composting technology for earthworm-enhanced degradation of cow dung, which belongs to the field of agricultural technology. Background technique

[0002] With the rapid development of rural animal husbandry, the impact of a large amount of livestock and poultry manure on the environment is becoming increasingly serious, especially in lake basins. Because there are still no relatively perfect facilities and methods for collecting and processing livestock and poultry manure, a large amount of livestock and poultry manure produced in rural areas every day is basically in a state of random piles. These random piles of livestock and poultry manure are rich in nutrients such as nitrogen and phosphorus, which are easily lost into the lake, causing eutrophication of the water body and destroying the ecological environment.

[0003] As an important agricultural solid waste, livestock and poultry manure is only returned to t...
