NOVELTY - Housefly metabolic ecological conversion of straw fast intensive treatment involves collecting fly clean and feeding domesticating; transforming rice suitable for inducing and stable and plant the rice machine, inducing and culturing the housefly larva; induced straw training materials from straw powder; obtaining stable high expression of the cellulase fly; adding white rot fungus culture solution in crushed straw and ferment to obtain modified straw powder; producing fly maggot industrial product; and drying fly maggot production of industrial product.    USE - For metabolic ecological conversion of straw selected from sorghum straw, corn straw, cotton straw, and wheat straw (claimed).    ADVANTAGE - The method uses biological technology to fly a straw ecological transformation functions and screening, engineering, combined with mechanical crushing, microbial fermentation technology, the modern engineering technology, the microbial fermentation, insect metabolic conversion of straw resources; has high accuracy of pigment application, and ecological biological utilization degree; and has short rotten period, high product quality, high added value, no environmental pollution.    DETAILED DESCRIPTION - Housefly metabolic ecological conversion of straw fast intensive treatment, involves collecting fly clean and feeding domesticating: collecting local wild housefly, fly is milk powder, sugar, cleaning the larva breeding is wheat bran, natural passage more than 5 generations, so it has stable propagation property; transforming rice suitable for inducing and stable and plant the rice machine to crush into 50-800 meshes, lignin structure, then adding wheat bran and water to water content is 50-90% of straw culturing material, where the environment temperature is 20-30 degrees C, the relative humidity is 50-80% of the condition inducing and culturing the housefly larva; induced straw training materials from straw powder, wheat bran is 1:9 is added to straw powder, wheat bran is 8:2, each of the proportion for 5-15 to obtain straw into suitable fly strain; high expression cellulase for breeding fly the straw conversion suitable for the larva and inoculating plant is straw powder, wheat bran is 6:4 of straw culturing material, random packet, each generation the crude fiber content in the culture material for measuring the lowest group pupation to fly, using genetic screening method for obtaining secretion of cellulose high expression of fly in the culture material of crude fiber content is less than 15% to obtain stable high expression of the cellulase fly; straw fly maggot biological conversion pre-processing: mechanical crushing straw into 50-800 meshes, adding white rot fungus culture solution open to ferment for 1-3 days, obtaining the modified straw powder, by weight, take modified straw powder, 50-70% of wheat bran or bran or bagasse, 20-30% protein and 10-20% of auxiliary material, uniformly mixing and adjusting pH value of the solution to 6.5-7.5, till the water content is 65-75%, preparing fly maggot industrial production charge; industrial straw into stable fly strain of the high expression cellulase fly larvae of fly maggot in industrial production of primer, 10-15 cycles obtained after industrial straw into fly strain, and strain to fly maggot industrial production of product; fly maggot production of industrial product, the residual charge after drying fly maggot grow made functional organic fertilizer, housefly larva and fly is made of animal health feed or adopting biological technology process is made of biological medical material or product.
