Quick and intensive straw management method based on ecological conversion via housefly metabolism

Abstract

The invention discloses a quick and intensive straw management method based on ecological conversion via housefly metabolism. The method comprises the following steps of: housefly species collection and clean breeding and acclimatization, induction and stabilization of straw conversion adaptation housefly strains, breeding of cellulose high expression housefly strains, pretreatment of straw housefly maggot bioconversion, stabilization of industrialized straw conversion housefly strains, and production of industrialized housefly maggot products. Compared with the prior art, the method has the advantages that biotechnologies are adopted for functional induction and filtration of seed maggot straw ecological conversion, passage and engineered cultivation, a machinery crushing method and a biofermentation technology are adopted, and a modernized engineering means is adopted, so that intensive straw management based on microbe fermentation and insect metabolic conversion is realized. Compared with other methods, the method provided by the invention has the advantages of high ecological degree, high bioavailability, short rotten period, high product quality, high extra-value output of resources, non-environmental pollution, and scientific proportion and high fertilizer efficiency.

Description

technical field [0001] The invention relates to a method for fast and intensive treatment of straw mainly based on the metabolic ecological transformation of housefly, and belongs to the technical field of housefly breeding and waste utilization. Background technique [0002] As a large agricultural production country, with the development of modern agriculture in my country, the scale of grain continues to expand, and the output of crop straws, especially corn straws, cotton straws, wheat straws and rice straws, etc. has increased rapidly. In 2010, according to statistics, the country produced a total of more than 800 million tons of straws . In terms of its material properties, straw is a very good usable material. It has been widely used since ancient times and can be summarized as "five materials", namely fuel, feed, fertilizer, base material, and raw material. At present, as far as the country is concerned, more than 50% of straw production is mainly processed by direct...

AI Technical Summary

Problems solved by technology

The disadvantage of the traditional silage fermentation method is that only fresh straw can be used, and there is nothing to do with dry straw, and the crude protein content is low. The feed made by this method can only be used for feeding ruminant livestock.

But there are also disadvantages: (1) The technology is immature. Under the current technical level, the cost of biomass power generation is much higher than that of conventional coal-fired power generation, which is about 1.5 times that of coal-fired power generation; (2) The cost of straw purchase, transportation and storage High, straw has light specific gravity, low density, and large volume; due to the huge straw consumption of power generating units, the straw in a single place cannot meet the fuel requirements of the power plant, and it takes one province or even multiple provinces to obtain sufficient straw fuel, and the transportation cost is huge In addition, the purchase of straw has a strong seasonality and cannot be purchased in a balanced manner. To maintain the normal operation of the enterprise, there must be a storage capacity of half a year; Rain, moisture-proof, fire-proof and other supporting equipment, investment construction and maintenance costs are large; (3) Although the pollution of straw power generation is low, it is not really zero pollution, and it has almost no feedback effect on agriculture

Therefore, no matter returning the straw to the field by composting or fermenting the straw as feed, it is far from enough to consume the amount of straw, and the existing technology production is not satisfactory in terms of fertilizer efficiency or feed breeding effect, so farmers have to choose to burn straw

[0014] 2. my country's current agricultural production model is retail-based agricultural production, which leads to a large amount of transportation costs and other additional costs arising from the centralized processing of straw

Therefore, regardless of whether it is straw fermentation for biogas or straw making board, although the technology is very mature, due to the high cost, farmers cannot get good benefits, the enthusiasm for participation is not high, and the promotion of the project is slow.

[0015] 3. Some key production technologies are immature, such as straw power generation. Its advantages are very obvious, but its shortcomings are also obvious. The increase in cost due to immature technology is the main reason for the slow promotion of technology

At present, there is no relevant technical report on the efficient ecological transformation of housefly to treat straw
