    The main effect of microbial fertilizer is to improve the soil environment and promote the development of plant rootsAs long as we know the importance of plant roots, we can know that the various functional microorganisms contained in bio-organic fertilizer enter the soil and produce a large number of secondary metabolites during growth and reproduction, which can promote the formation of soil particle structureThe formation of the clump structure can make the soil become loose, soft, water retention and fertilizer performance is enhanced, water, gas, heat more coordinated, reduce soil formation, is conducive to water conservation, fertilizer, ventilation and promotion of root development, to provide a comfortable growth environment for cropsof course, consider the main ingredient of microbial fertilizer is bioactive bacteria, in the process of use there are the following shortcomings:1, see the microbicide on death, can not be mixed with fungicides, prevention and treatment of root rot, root cancer and other soil-related disease s; 2, see ultraviolet light on death, autumn fertilization period for the best stage of the sun's ultraviolet quality, ultraviolet light can kill the biological activity bacteria in the microbial fertilizer ; 3, mixed with fertilizer should pay attention to the amount of fertilizer can not be too largeHigh concentrations of chemical substances have toxic effects on microorganisms in the fertilizer, especially attention can not be mixed with alkaline fertilizersuch as ammonium bicarbonate and physiological alkaline fertilizer such as sodium nitrate, the condition on which the bacteria in the manaure depend seismoofis is organic matterThere are enough organic matter or humus in the soil to be used by microbial bacteria, which in turn enables soil microorganisms to multiply quickly and activate nutrientsThe role of microbial bacteria in the soil is mainly to produce a variety of enzymes, break down a variety of nutrients, produce a variety of acids and carbon dioxide, to provide more nutrients to cropsAnd microbial bacteria to live and reproduce, soil must have enough organic matter to doSo we advocate organic fertilizer and use with bacteria fertilizer!again, different species in the soil will play a different role, for your referenceerythropoietin: can increase crop resistance, nitrogen fixationlarge spores: can release soluble phosphorus, potassium and calcium, sulfur, magnesium, iron, zinc, vanadium, manganese and other trace elementsLichensporine: can resist disease, kill harmful bacteriaSuyun Golden Spore: can kill insects (including root lineworms), with specific toxic activity on arthropods such as scaly finsglial spore: has the function of phosphorus, potassium release and nitrogen fixation, can secrete a variety of enzymes, enhance the resistance of crops to some diseases Puyang streptomycin: has the ability to enhance soil fertility and stimulate crop growth root fungus: it expands the absorption surface of the root system and increases the absorption capacity of elements (especially phosphorus) outside the absorption range of the original root hair photosynthesis: fertile soil and the main force for animal and plant growth coagulation spore: can reduce the environment of ammonia, hydrogen sulfide and other harmful gases, improve the content of amino acids in the fruit rice citamy: the organic matter in straw can become the nutrient needed for plant growth, improve the soil organic matter content, improve soil structure pale purple penicillin: for a variety of nematodes have prevention and control effect, is the most promising preparation for the prevention and control of root knot nematodes the improvement of soil physical and chemical characteristics, strengthen the activities of beneficial microorganisms in the soil, so as to maximize the decomposition and transformation of organic matter, produce a variety of nutrients and stimulants, which in turn stimulates the growth and development of microorganisms, promotes crop growth, and ultimately achieves the goal of increasing yield and increasing income In addition, functional microorganisms form an advantageous population around the root system of the crop, inhibit or suppress the growth and reproduction of harmful pathogens, reduce the degree of disease in the crop, and thus play a role in increasing yield root system weakness: what does the root system rely on? first of all, the root water fertilization, so that the root system has an internal outward elongation of the stimulation, lack of organic matter soil water content poor, all kinds of fertilizer solution to the root "expression" of poor capacity, resulting in the root growth of the inherent stimulation is insufficient; the main reason for soil slab ingenuation is the absence of organic matter, not the use of fertilizers This is not to say that fertilizer has no effect on soil slats Without organic matter, the intensity of fertilizer's influence on soil slatting becomes more prominent The abundance of organic matter, fertilizer utilization rate has been greatly improved, fertilizer residue in the soil sulfate, chloride ions, nitrites and other substances will be converted to water-soluble organic compounds, as well as rich soil microorganisms and the multiple effects of harmless, so that the land can be sustainable farming so in the final analysis, the negative effect of fertilizer "making soil slab" is not the result of fertilizer being used, but the result of people ignoring the application of sufficient amounts of organic fertilizer to the soil the lack of organic matter in the soil, the lack of carbon sources required for microbial reproduction, resulting in sparse inter-root microbiome, the external stimulation of root growth is too weak, the root system loses the external stimulation of growth soil slab and drug damage (severe pesticide residues in soil) cause dissothing crop diseases If the soil is rich in organic matter, these hazards can be mitigated or even avoided
