Microbial fertilizer refers to a specific product containing living microorganisms. Apply it to agricultural production to obtain a specific fertilizer supply. There is an essential difference between him and micro-fertilizer. The former is a living life, and the latter is a mineral element. Microbial fertilizers can be summarized into three categories: one is through the life activities of microorganisms, increasing the supply of plant nutrient elements, resulting in improved plant nutrition. The life of microorganisms antagonizes each other in the soil and harmful microorganisms, and can also produce resistance to disease, disease, and even pest control. The amount of microbes is about 2 kg per mu. This type of representative products are rhizobia, nitrogen-fixing bacteria, phosphorus-solubilizing bacteria and silicate bacteria (potassium bacteria). The other is the metabolites of microorganisms, such as amino acids, yellow phytic acid, etc., and it is combined with mineral trace elements to make a liquid or solid product, so as to stimulate the growth of crops or resist pests and diseases. Each grain of land uses about 100 grams of grain. The other type is the function of microorganisms to decompose organic matter. For example, fermentation or enzyme bacteria can accelerate the decay of farmyard manure or straw and increase the effect of soil humus. Many such chemical fertilizers are used in this category to ensure the nutritional requirements of the crops. The market is called multiple organic fertilizer. Such as "EM" beneficial bacteria. More than 1,000 kilograms per mu are used. Microbial fertilizers can be used for seed dressing, soaking, rooting, rooting, top dressing, furrowing, or hole application. However, seed dressing is the most convenient, economical and effective method. The seed dressing method is to transfer the solid bacteria fertilizer with clear water to a paste or liquid bacteria agent and add water to dilute, and then stir well with the seed, dry a little to dry and thickly sow, and immediately cover the soil. Some fungus fertilizers can also be mixed with fertilizers as base fertilizers. Microbial fertilizers are bioactive fertilizers and therefore have specific fertilizer requirements. The first is to avoid long-term use after opening the bag. After opening the bag for a long period of time, the others may invade into the bag, causing the microbial flora to change and affect its use effect. The second is to avoid use under conditions of high temperature and drought. Under conditions of high temperature and drought, survival and vice versa will be affected and cannot play a good role. The use of such fertilizers should be selected on a cloudy or sweet evening, combined with the cover soil and manure tax, to prevent the microbial fertilizers from being exposed to direct sunlight or due to insufficient water to make them difficult to function. The third is to avoid mixing with decomposing farmyard fertilizers. Such fertilizers are used for heaping or mixing of decomposed organic fertilizers, which can kill microorganisms due to high temperatures and affect the exertion of microbial fertilizers. At the same time, care must be taken to avoid mixing with over-acid and over-alkaline fertilizers. The fourth is to avoid simultaneous use with pesticides. Chemical pesticides will inhibit the growth of microorganisms to varying degrees and vice versa, and even kill microorganisms. If you need to use pesticides, you should also stagger the use of time. Can not use insecticide, fungicide seeds mixed with microbial fertilizers.
