Highly-efficient treatment method for cattle manure based on high-density earthworms

Abstract

The invention discloses a highly-efficient treatment method for cattle manure based on high-density earthworms. The highly-efficient treatment method comprises the following steps: (1) site preparation; (2) feed preparation: a, uniformly mixing 80 to 90 parts of the cattle manure and 10 to 20 parts of EM microbial liquid, and carrying out fermentation for 15 days; b, uniformly mixing fresh corn straw, 4 to 8 parts of wheat bran and 8 to 12 parts of the EM microbial liquid, carrying out compaction, and carrying out sealed fermentation for 15 days; c, mixing the fermented cattle manure and the fermented corn straw, adding 0.4 to 0.8 part of urea, 0.5 to 1 part of plant ash and 0.02 to 0.04 part of citric acid, carrying out full and uniform mixing, and carrying out sealed fermentation for 10 days so as to obtain a mixture A; and d, fully mixing 5 to 10 parts of earthworm manure with the fermented mixture A, spreading the obtained mixture, carrying out drying under the sun for 2 to 3 days, then carrying out placing onto an earthworm bed in a greenhouse, and fully spraying clarified lime water; (3) earthworm placing; and (4) daily management. The invention has the following advantages: through preparation of a feed and improvement of processing steps, the highly-efficient treatment method provided by the invention greatly improves the treatment efficiency of the cattle manure, and increases economic benefits of enterprises.

Description

technical field [0001] The invention relates to a cow dung treatment method, in particular to a high-efficiency cow dung treatment method based on high-density earthworms. Background technique [0002] In recent years, with the development of the economy and the improvement of people's living standards, the demand for livestock and poultry products has continued to increase. The adjustment of the agricultural industry structure has been further deepened. The intensive breeding of livestock and poultry has developed rapidly in my country, and the production scale has continued to expand. In areas where breeding is relatively concentrated, a large amount of casually discarded cow dung has blocked rivers and ponds, polluted the soil, and has endangered the quality of groundwater. However, from the perspective of material circulation and energy flow in the ecosystem, cow dung is not a pollutant, but a resource, which has great utilization value. [0003] As a kind of organic wa...

Problems solved by technology

[0004] At present, although the technology of using earthworms to process cow dung is relatively mature, this technology is based on the technology of earthworm farming. In the existing earthworm farming technology, prolonging the cycle of feed addition and the nutritional structure of feed has been the main solution for the aquaculture industry for a long time problem, but it is not applicable to the problem of fast processing of cow dung, which slows down the processing speed of cow dung, and the density of earthworms cannot be too high when processing cow dung, resulting in unsatisfactory processing efficiency. In the long run, this technology Far from playing its due role and not being favored by farmers

[0005] Combined with the existing vermiculture technology, there are still some technical defects in the application of high-efficiency treatment of cow dung, such as: the need to frequently measure the pH value of the manure; the proportion of cow dung is small, which affects the efficiency of treatment and increases The storage area of ​​cow dung is reduced; the disease problem of earthworms is still prominent in the existing technology; the cost of feed preparation is relatively high
