Soil improvement biofertilizer without chemical residual

Abstract

A disclosed soil improvement biofertilizer without chemical residual is characterized by comprising the following substances in parts by weight: 50-60 parts of shell powder, 100-110 parts of chicken manure, 20-30 parts of rice bran, 34-46 parts of wheat bran, 15-30 parts of solanum tuberosum, 1-3 parts of remote lemongrass herb, 9-14 parts of field sowthistle herb, 3-8 parts of phosphorus mineral powder, 14-16 parts of calcium dihydrogen phosphate, 4-7 parts of calcium dihydrogen phosphate, 6-12 parts of phosphoric acid, 2-7 parts of manganese sulfate, 1-4 parts of zinc sulfate, and 3-9 parts of urea. Compared with the prior art, because the soil improvement biofertilizer employs chicken manure, phosphorus mineral powder, shell powder, rice bran and other natural materials which are abundant in mineral substances, the biofertilizer enables soil to not be caked, and solves the pollution problem caused by straw incineration.

Description

technical field [0001] The invention relates to a soil improving biological fertilizer without chemical residue. 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 have ...

Problems solved by technology

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 have to use increase The application of chemical fertilizers, if things go on like this, will inevitably aggravate soil compaction on the one hand, destroy the structure of soil aggregates, and make the soil fertility decline, and on the other hand, increase the investment in agriculture year by year
