The invention relates to technology for producing an organic fertilizer by using bamboo shoot hulls serving as raw materials through mixed compositing fermentation. The technology comprises the steps of: cutting and crushing the bamboo shoot hulls, performing screw extrusion dehydration on the bamboo shoot hulls, adding fermented ruminant manures into the bamboo shoot hulls, mixing the materials uniformly, and delivering the materials in a trench type fermenter for compositing fermentation; when the temperature of the materials rises to between 60 and 70 DEG C, performing stack-turning on thematerials for oxygen supply by using stack-turning equipment, and further dehydrating the materials; in a high-temperature period, performing the stack-turning at least once each day, and after acid content of the extruded juice is adjusted, returning the juice to the composting uniformly; and after the fertilization is completed, according to different purposes, packing the composting directly or packing crushed composting to obtain the organic fertilizer, or performing extrusion granulation on the composting to obtain the organic fertilizer. The technology is simple and feasible, can realize the resource utilization of the waste bamboo shoot hulls, does not generate secondary pollution, and provides a safe and pollution-free fertilizer for agricultural production while solving the pollution problem.

The invention discloses a preparation method for peptide chelated calcium of clanis bilineata tsingtauica larva. The preparation method comprises the following steps: degreasing the clanis bilineata tsingtauica larva and then carrying out superfine crushing, adding water and uniformly mixing, and adjusting the pH value to 2-9; adding protease in the obtained mixed liquid, stirring for enzymatic hydrolysis, then inactivating the protease to obtain a crude enzymatic hydrolysate, and centrifuging to obtain an supernatant liquid; taking the obtained supernatant liquid and removing impurities to obtain a purified liquid, and carrying out separation and purification by virtue of at least one ultrafiltration membrane with a molecular weight cut-off of 1-50kD to obtain enzymatic hydtolysis peptide components with different molecular weights; adding a calcium source, and chelating to obtain a crude peptide chelated calcium product of the clanis bilineata tsingtauica larva; and collecting precipitates after concentration and precipitation, and drying to obtain the peptide chelated calcium product of the clanis bilineata tsingtauica larva. According to the method disclosed by the invention, a method of classifying through the ultrafiltration membranes with different molecular weight cut-off at first, and then chelating is adopted for the enzymatic product, on one hand, the technical bottleneck that a peptide calcium chelate is difficult to separate is solved; and on the other hand, the peptide chelated calcium products with different molecular weights of the clanis bilineata tsingtauica larva are prepared and can be used by people with different needs, thus the use efficiency of the products is increased, and the pertinence of the products is improved.
