Problems solved by technology

In the past ten years, the total consumption of chemical fertilizers in my country has increased by 90.7%, while the total grain output has only increased by 9.1%. The use of chemical fertilizers per unit area is 1.6 times the average level of the United States and the world. It means that the more chemical fertilizers are used, the greater the economic loss and the more serious the environmental pollution. Due to the long-term use of chemical fertilizers and pesticides, the soil is compacted and the soil fertility is reduced, which seriously affects the quality of the soil environment and the quality of crops.
At present, heavy metal pollution, organic matter pollution, agricultural chemical pollution, and pesticide residues in the soil in our country have caused DNA mutations in some insects and bacteria, resulting in aggravated pests and diseases, resulting in a decline in the quality and output of agricultural products, seriously affecting the environmental quality of our country.

Abstract

A biologic fertilizer for activating microbes, loosening soil, decomposing the residual chemical fertilizer, agricultural chemicals and heavy metals, and increasing the yield of agricultural crops is prepared through culturing yeast, mixing it with rice husk, brown sugar and shale powder, adding the mixture to city sludge, stirring, stacking for fermenting for 5-7 days while re-stacking once per day and adding calcium perphosphate, adding N and K fertilizers, stirring and granulating, and packaging for storing.

Description

Technical field [0001] The invention relates to an urban sludge biological fertilizer, which belongs to the technical field of biological fertilizers. Background technique [0002] At present, known crop fertilizers mostly use chemical fertilizers. In the past ten years, the total consumption of chemical fertilizers in my country has increased by 90.7%, while the total grain output has only increased by 9.1%. The use of chemical fertilizers per unit area is 1.6 times the average level of the United States and the world. It means that the more chemical fertilizers are used, the greater the economic loss and the more serious the environmental pollution. Due to the long-term use of chemical fertilizers and pesticides, the soil is compacted and the soil fertility is reduced, which seriously affects the quality of the soil environment and the quality of crops. At present, heavy metal pollution, organic matter pollution, agricultural chemical pollution, and pesticide residues in t...
