A biological compound fertilizer containing nimbin, using Aspergillus awamori, Coccidioides mollii, Bacillus subtilis and Geotrichum candidum as strains, the strains are cultured and enlarged to make a mixed bacterial agent according to 3:1:3:2; According to the weight ratio, the mixed bacterial agent is mixed with organic compound, urea and phosphate rock powder, and then neem tree seed powder is added to prepare the biological compound fertilizer containing neemin. The biocomposite fertilizer containing neemin prepared according to the present invention can inhibit nitrification, can significantly improve the utilization rate of nitrogen fertilizer, can reduce the loss rate of urea by 50%, and reduce the loss rate of ammonium nitrogen fertilizer or nitrogen fertilizer containing ammonia by 25%; and It has a certain function of avoiding rodents and killing insects, and at the same time activates soil nutrients, improves crop quality, promotes plant growth, and increases crop yield by an average of 25.7%. The formula is reasonable, the process is simple, and the quality is stable, and it is a new biological compound fertilizer containing neemin.

The invention relates to a biological organic fertilizer used for aquaculture paddy fields and a production method thereof. The fertilizer is prepared by the raw materials according to the parts by weight: 0.3 to 0.5 parts of taurine, 2 to 3 parts of streptomyces hygroscopicus, 2 to 3 parts of chromagenic streptomyces aureofaciens, 2 to 4 parts of bacillus cereus, 2 to 4 parts of bacillus sphaericus, 9 to 13 parts of bacillus mucilaginosus, 2 to 3 parts of azotobacter chroococcum, 2 to 3 parts of streptomyces microflavus, 10 parts of fruit waste degradation products, 10 parts of matrix and 46.5 to 57 parts of soil. In the method, as fruit waste degradation product polysaccharide carbohydrate is mixed with nitrogen-fixing, phosphate-dissolving and potassium-dissolving active compound microorganisms and a compound actinomycete agent which has antagonistic effect on rice blast and rice sheath blight, and matched with nutritional components which stimulate the growth of fisheries in rice fields, the biological organic fertilizer can not only be used for improving soil microbial community structure, activating soil nutrients, and improving rice rhizosphere nutrition, increasing the yield and improving quality of rice and improving water quality, but also promote the growth of cultured fisheries in rice fields.

The invention relates to an organic fertilizer prepared by animal skin materials and collagen waste materials. The organic fertilizer comprises the following components: waste collagens, waste cow skins, waste casings, sawdust and zymophyte. The raw materials of the prepared organic fertilizer are from wastes and unqualified protein casings left in a preparation process of collagen protein casings, and the wastes are subjected to treatment in a general trash treatment way so as to easily cause pollution remission. In order to save energy sources, the wastes are developed into useful objects, and based on a lot of researches, the wastes are finally determined to be utilized, so that the aim of turning the wastes into the treasures can be fulfilled.

The invention discloses a multifunctional seedling cultivation substrate which comprises the components of EM fermented maize straws, perlite, vermiculite and prohexadione calcium, wherein the volume ratio of the EM fermented maize straws, the perlite and the vermiculite is 6: 3: 1, and the amount of the prohexadione calcium is 10-20g / m<3>. The multifunctional seedling cultivation substrate can control excessive growth of seedlings and can effectively prevent side effects of sprayed conventional growth inhibitors, and cultivated seedlings are superior to existing conventional seedling cultivation substrates in root activity, strong seedling index, yield and other aspects. Meanwhile, using amount of grass carbon is reduced, grass carbon resource saving is facilitated, and the purposes of resource utilization of agricultural wastes and environment pollution reduction are achieved.
