Green biological fertilizer for producing safe agricultural products

Abstract

The invention discloses a green biological fertilizer for producing safe agricultural products, and the green biological fertilizer comprises the following materials in parts by weight: 20-30 parts ofchicken manure, 50-70 parts of pig manure, 15-25 parts of rice bran, 0.01-0.02 part of trace elements, 0.5-1.0 part of chitin, 0.1- 0.2 part of polypeptide, 3-7 parts of potassium polymetaphosphate,2-9 parts of potassium pYRophosphate, 3- 4 parts of sodium aluminum phosphate, 1 to 6 parts of calcium hydrogen phosphate, 2 to 6 parts of calcium phosphate, 3 to 4 parts of calcium pYRophosphate, 5 to 9 parts of humic acid, and 0.1 to 0.3 parts of verticicladiella powder. Compared with the prior art, because the natural materials such as the chicken manure, phosphate rock powder, shell powder, and shredded crop straw and rice bran are used, the materials are rich in minerals, soil does not agglomerate, and the pollution problem of straw burning can be treated.

Description

technical field [0001] The invention relates to a green biological fertilizer providing agricultural product quality. Background technique [0002] In the prior art, chemically synthesized fertilizers, including urea, are mostly used for fertilizing crops. The application of chemical fertilizers has led to a rapid development of agricultural production, but chemical fertilizers pollute the environment, compact the soil, destroy the soil structure, and gradually exterminate many beneficial microbiota in the soil, resulting in the decline of soil fertility and the deterioration of crop quality and other defects. In addition, the application of organic fertilizers on the soil where chemical fertilizers have been applied, due to the lack of decomposition of beneficial microorganisms, the nutrients in them cannot be released for absorption and utilization by crops, so the fertilizer and absorption rate are low, and the fertilizer efficiency is poor. To improve soil fertility, we ...

The application of chemical fertilizers has led to a rapid development of agricultural production, but chemical fertilizers pollute the environment, compact the soil, destroy the soil structure, and gradually exterminate many beneficial organisms in the soil, resulting in the decline of soil fertility and the deterioration of crop quality and other defects.

In addition, the application of organic fertilizers on the soil where chemical fertilizers have been applied, due to the lack of decomposition of beneficial microorganisms, the nutrients in them cannot be released for absorption and utilization by crops, so the fertilizer and absorption rate are low, and the fertilizer efficiency is poor. To improve soil fertility, we have to use increase The application of chemical fertilizers, if things go on like this, will inevitably increase soil compaction on the one hand, destroy the structure of soil aggregates, and further reduce soil fertility, and on the other hand, increase agricultural investment year by year
