Realizing soil ecological balance can inhibit the occurrence of soil-borne diseases. We need to master two aspects: first, increase the organic matter in the soil, apply farm manure, organic fertilizer produced by factories, return straw to the field and plant green manure crops such as sweet clover; The second is to increase the species and quantity of beneficial microorganisms by applying bacterial fertilizer. Bacterial fertilizer contains a large number of microorganisms, which can improve the nutritional conditions of crops, decompose organic matter in soil and transform it into nutrients that plants can absorb. Note that only when organic matter and beneficial microorganisms coexist can the effect of fattening and disease prevention be achieved.
At present, there are many kinds of multi-effect organic fertilizers, and their beneficial microorganisms are implanted into a large number of organic substances in a proper proportion. For example, Jinmantian biological fertilizer includes nitrogen-fixing bacteria, Bacillus megaterium, Bacillus mucilaginosus, photosynthetic bacteria, lactic acid bacteria and so on 150 strains. Nitrogen-fixing bacteria convert molecular nitrogen into ammonia nitrogen through nitrogen fixation, and further synthesize organic nitrogen for crop application; Phosphorus-solubilizing bacteria can transform organic phosphorus and insoluble inorganic phosphorus in soil into soluble inorganic phosphorus. For example, phosphate-solubilizing microorganisms can decompose organophosphorus by phosphatase, and phosphate mainly composed of tricalcium phosphate can be dissolved by phosphate-solubilizing microorganisms. Some research results show that crops can accept phosphorus. Potassium-solubilizing bacteria can decompose silicate minerals, such as feldspar and mica, to produce potassium for crop growth. The three microbial preparations can provide crops with comprehensive trace elements such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, boron, zinc, manganese and molybdenum.
