Fermented biofertilizer prepared from waste vegetables, straw and livestock and poultry feces and preparation method thereof

Abstract

The invention relates to a method for preparing biofertilizer by fermenting waste vegetables, straw and livestock and poultry feces. The fermented biofertilizer is prepared from the following raw materials in parts by weight: 90-110 parts of waste vegetables, 45-55 parts of straw, 18-22 parts of livestock and poultry feces, 6-10 parts of rice bran, 1.7-2.0 parts of urea, and 1.7-2.0 parts of ammonium sulfate. The invention also provides a preparation method of the fermented biofertilizer prepared from waste vegetables, straw and livestock and poultry feces. The preparation method comprises the following steps of: crushing the waste vegetables till particle size is below 10 mm, crushing the straw till particle size is below 10 mm, adding 45-55 parts by weight of straw, 18-22 parts by weight of livestock and poultry feces, 6-10 parts by weight of rice bran, 1.7-2.0 parts by weight of urea, and 1.7-2.0 parts by weight of ammonium sulfate to 90-110 parts by weight of waste vegetables, mixing, adjusting the water content of the mixed material to 50-65%, adding 0.08-0.12% of composite microorganism agent and 0.008-0.010% of composite enzyme based on the weight of the mixed material, sufficiently and uniformly stirring, controlling water content of the fermentation material to be 50-65%, adjusting the pH to 6.2-7.8 with 1% lime water, and carrying out aerobic fermentation for 10-20 days to obtain the biofertilizer product.

Description

technical field [0001] The invention relates to a method for preparing bio-fertilizer by fermenting end vegetables and stalks of livestock and poultry manure. Background technique [0002] Tail vegetables refer to the waste vegetable leaves and sides that are cut off during the preparation of refined vegetables, accounting for about 1∕3-1∕2 of the refined vegetables. If these wastes are not properly treated and piled up randomly, they may cause rot and deterioration , every summer and autumn vegetable harvest season, these a large number of rotten tail vegetables will have mosquitoes and flies, the smell is not good, and it will seriously pollute the environment. The current method of processing the tail vegetables is to send the tail vegetables to the expensive vegetable cake making machine, through the process of cleaning, crushing and pressing, and then drying the filter residue to make vegetable cakes or fertilizers. This treatment method is a waste of water resources ,...

Problems solved by technology

[0003] The traditional straw livestock and poultry fertilizer method is to use the indigenous microorganisms in the raw materials to degrade the organic matter. However, due to the small number of indigenous microorganisms in the early stage of fertilizer making, it takes a long time for these microorganisms to reproduce, and they are harmful to the organic matter. The decomposition rate is also very different. Therefore, the traditional straw livestock and poultry fertilizer method has a long cycle, produces a strong odor, and has low fertilizer efficiency.
