Problems solved by technology

Due to the quick and intuitive effect of chemical nitrogen fertilizer, it is easy to be abused by farmers in large quantities, resulting in a serious imbalance in fertilization
Chemical compound fertilizers, especially high-concentration chemical compound fertilizers, cause excessive concentration of chemical fertilizers in farmland and more loss
Long-term unreasonable fertilization, especially a large amount of long-term use of chemical fertilizers, will easily lead to a decrease in organic matter content in the soil, soil acidification, compaction, imbalance of soil flora, increase of harmful bacteria and harmful substances, and decline of soil fertility
The abuse of chemical fertilizers and pesticides has also caused a large increase in chemical residues and other harmful substances in agricultural products, and the quality has declined, affecting human health and survival

Abstract

The invention discloses a biological organic fertilizer for preventing and controlling soil-borne diseases and a preparation method thereof. The biological organic fertilizer is prepared from the following raw materials in parts by weight: 100 to 150 parts of sheep manure, 60 to 80 parts of chicken manure, 50 to 60 parts of edible fungi residue, 70 to 80 parts of corn stalks, 1 to 2 parts of EM bacterial agents, 2 parts of fermentation accelerators and 1 part of composite fermentation agents. The biological organic fertilizer for preventing and controlling soil-borne diseases has the advantages that the biological organic fertilizer has the advantages that the formula is reasonable; economic performance, effectiveness and environment protection are realized; the crop yield can be obviouslyimproved; the soil-borne diseases can be effectively prevented and controlled; the soil structure can improved; through the cooperated effects of each ingredient, the utilization rate of the fertilizer is greatly improved; the requirements of the crop on the nutrients can be met; the fertilizer effect is achieved to the maximum degree; the yield and the quality can be improved; the fertilizer belongs to an ideal biological green environment-friendly fertilizer.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, in particular to a bio-organic fertilizer for preventing and controlling soil-borne diseases and a preparation method thereof. Background technique [0002] At present, in most areas of our country, especially the agriculturally developed areas, the application of nitrogen fertilizers seriously exceeds the standard, the return rate of chemical fertilizers decreases year by year, and causes serious pollution. After the application of phosphate fertilizer, generally 75-85% is immobilized, and the effective utilization rate is low. Chemical potash fertilizers are all soluble salts, except for runoff loss, 60% seeped into the non-cultivated layer below 60cm. Due to the quick and intuitive effect of chemical nitrogen fertilizer, it is easy to be abused by farmers in large quantities, resulting in a serious imbalance in fertilization. Chemical compound fertilizers, especially high-concentration c...
