Application of bacterial fertilizer can inhibit soil-borne diseases

In order to achieve higher yields, humans have used fertilizers and pesticides continuously and in large quantities in farmland. The organic matter in the farmland is scarce, and the types and quantities of microorganisms are greatly reduced. Among them, some beneficial microorganisms, such as actinomycetes, Trichoderma, and Bacillus, which inhibit soil-borne diseases, are also included. On the other hand, many pathogens that are harmful to plants are more likely to overwinter in sick bodies. If there is no saprophytic bacteria in the soil, the plant straw can't rot quickly, and the germs will have more chances to survive. It is also because of the above reasons that blight, sheath blight, root rot, and blight have become increasingly rampant.

Two strategies can be adopted for the growing problem of soil-borne diseases. First, continue to strengthen chemical or physical killing measures, and create aseptic conditions for crops as much as possible. This is difficult because the structure and physical and chemical properties of the soil are complex, and many factors affect the sterilization effect; even if it can be done temporarily, once a new pathogen enters, it will quickly become a disaster due to lack of natural inhibition. Another strategy is to increase the number and quantity of microbes in farmland soils, create a rational, balanced and stable microflora and rely on their competition, occupancy, and heavy parasitism to inhibit the growth of pathogens. Practice has proved that this is a reasonable strategy for continuous disease prevention.

To achieve ecological balance and inhibit soil-borne diseases, on the one hand, it is necessary to continuously increase soil organic matter, including farmyard manure (fertilizer, compost), industrial production of organic fertilizer, straw returning, and planting grasshoppers and other green manure crops. Organic matter not only contains abundant nutrients, but also forms agglomerate structure in the soil, and is also a substrate for cultivating various microorganisms. On the other hand, it is necessary to increase the type and quantity of beneficial microorganisms, that is, to apply a certain amount of bacterial fertilizer. Bacterial fertilizer is also called biological fertilizer and bacterial fertilizer. Rather, they are bacteria rather than fertilizer, the main ingredient is not a nutrient, but a large number of microorganisms. Its function is to improve the nutrient conditions of the crops and decompose the organic matter in the soil through the activities of microorganisms, so that they become nutrients that can be absorbed by plants, just as the food that people eat must be digested to be absorbed. If the straw is returned to the field without the help of microorganisms, it can not only be used by plants, but also may contribute to the growth of pathogens; on the other hand, no matter how much more bacteria are scattered in the poor soil, it is impossible to convert nutrients out of thin air. Beneficial microorganisms will also starve to death. Only when organic matter and beneficial microorganisms coexist can the effect of fattening and disease prevention be achieved.

A novel multi-effect organic fertilizer implanting beneficial microorganisms in a large amount of organic substances in an appropriate proportion, the microorganisms comprising nitrogen-fixing bacteria, nitric acid bacteria, phosphorus-dissolving bacteria, photosynthetic bacteria capable of increasing or transforming nutrients; and yeast capable of decomposing organic matter; It is capable of secreting plant growth stimulating hormone and inhibiting pathogens of Trichoderma harzianum, Myxobacteria, Actinomycetes, and some Bacillus and Pseudomonas. The fertilizer has the advantages of long-acting, quick-acting, increasing production and preventing disease, and is worth promoting. Its pros and cons mainly depends on the type and quantity of beneficial microorganisms implanted.
