Problems solved by technology

First, crop straws and rice husks after processing are burned in large quantities. Although the relevant state departments have banned the burning of straws and chaffs many times, due to the limited use of straws and chaffs in rural areas, there are still a lot of bans. There are still a large number of Straw and chaff are burned, which seriously pollutes the air environment
The second is that untreated poultry manure is discharged into rivers and lakes randomly, causing water pollution and increasing the load of biochemical oxygen demand (BOD), threatening the survival of fish, shellfish and algae; at the same time, agricultural waste pollutes irrigation water, using The ammonia nitrogen and protein nitrogen content in the water are too high, and excessive nitrate is produced in the underground aquifer, which endangers the growth of crops and breeds a large number of flies and other pests, seriously endangering human health
The third is that the excessive use of chemical fertilizers and pesticides in my country's planting industry has caused soil compaction, soil fertility decline, rampant pests and diseases, and agricultural environment pollution.

Abstract

The invention discloses an organic fertilizer produced by comprehensively utilizing straw, and a preparation method for the organic fertilizer, and relates to the technical field of agricultural fertilizers. The organic fertilizer is prepared from composted straw, 34 to 44 parts of rice hulls, 20 to 30 parts of composted animal dung, 10 to 15 parts of potassium chloride, 10 to 15 parts of humic acid, 0.4 to 0.6 part of medium and trace elements, 0.4 to 0.6 part of microorganism, 10 to 15 parts of calcium superphosphate and 5 to 10 parts of ammonium chloride through mixing and granulating. The organic fertilizer has the characteristics of low production cost, high bioactivity, high fertilizer efficiency, wide sources of raw materials and the like, can serve as a fertilizer for rice and a fertilizer for dry crops, vegetables, melons, fruits and fruit trees, and also can serve as a fertilizer for flowers.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to an organic fertilizer produced by comprehensive utilization of straws and a preparation method thereof. Background technique [0002] At present, my country's agricultural environmental pollution is becoming more and more serious, seriously threatening human health. First, crop straws and rice husks after processing are burned in large quantities. Although the relevant state departments have banned the burning of straws and chaffs many times, due to the limited use of straws and chaffs in rural areas, there are still a lot of bans. There are still a large number of Straw and chaff were burned, seriously polluting the atmosphere. The second is that untreated poultry manure is discharged into rivers and lakes randomly, causing water pollution and increasing the load of biochemical oxygen demand (BOD), threatening the survival of fish, shellfish and algae; at the s...
