Bacterial fertilizers are fertilizers that contain a large number of beneficial microorganisms and are based on the biochemical effects of these microorganisms to improve crop nutrient and growth conditions. The beneficial microorganisms are Rhizobium (biological nitrogen fixation), Phosphate-solubilizing bacteria (insoluble phosphorus in activated soil), Potassium-resolving bacteria, also known as silicate bacteria (decomposition and release of mineral potassium in the soil), and antibiotics such as "5406". (Can inhibit or kill harmful fungi and bacteria, stimulate crop growth and activate soil insoluble phosphorus) and enzyme bacteria (to promote the conversion of organic matter). The actual fertilizer efficiency of the fungus fertilizer is also often related to the matrix in which the microbial life activity is maintained. Biological fertilizers, as agricultural products, must meet certain quality requirements (NY227-94) in terms of viable counts, bacterial rates, and expiration dates. In addition to agricultural microbial agents, there are also compound microbial fertilizers and bio-organic fertilizers based on this. Compound microbial fertilizer refers to a living microbial product that is composed of specific agricultural microbes and nutrients and can provide, maintain, or improve plant nutrition and improve the yield or quality of agricultural products. According to the technical standards of NG/T798-2004, the total nutrient contents (N+P2O5+K2O) of liquids, powders, granules, etc. must not be lower than 4%, 6%, and 6%, respectively, but the content of fertilizers is not necessarily higher. The better, too high will inhibit microbial activity. Bio-organic fertilizer refers to the fertilizer produced by compounding specific organic micro-organisms and animal and plant wastes through harmless and humicified organic materials. It has the characteristics of microbial and organic fertilizers, and is based on the technical standard of NY 884-2004. The organic content of the fertilizer should not be less than 25%. Microbial fertilizers can be used as base fertilizers, topdressing fertilizers, can be applied to plants, or can be applied to seed dressing, soaking, rooting or foliar spraying, depending on the type of fertilizer. The agricultural bacterial agent mu is mixed with 2 kg of solid microbial inoculum and 40-60 kg of decomposed organic fertilizer and used as base fertilizer, top dressing or nursery; the solid microbial inoculant is mixed with nutrient soil to make nutrient mash, or mixed with dilute mud, in seedling Before sowing, roots are sowed; before sowing, seeds are immersed in 10 to 20 times dilution of the fungus or sprayed with a diluent, so that the seeds are fully contacted with the liquid biological agents before sowing; the seedlings are immersed in the roots to dilute 10 to 20 before transplanting. In the liquid bacterial inoculum, remove immediately, or spray the roots of the seedlings with the above dilution solution; dilute the bacteria to 100 times and then use it for root irrigation or flushing; dilute the bacteria to 500 times as foliar fertilizer. Compound microbial fertilizer can be used as basal fertilizer and topdressing, mu application rate of 10 to 20 kg; diluted 500 times for foliar fertilizer, spraying according to product specifications. Bio-organic fertilizer can be used as basal fertilizer and topdressing. When basal fertilizer is applied, the application amount is about 100 kg per mu. It is best to apply proper amount of farmyard fertilizer; the amount of topdressing fertilizer should be reduced appropriately, which should be applied 7 to 10 days earlier than chemical fertilizer, and appropriate quantitative fertilizer should be applied. In addition, when the soil N, P, K nutrient content is high or when a large amount of nitrogen, phosphorus and potassium fertilizers are applied, the effects of rhizobia, phosphate-solubilizing bacteria, and potassium-releasing bacteria fertilizers are reduced or even inhibited. For example, excessive application of nitrogen fertilizer can inhibit the activity of rhizobia. , to reduce root nodules nitrogen fixation. Also note that the beneficial microorganisms in the fungus fertilizer are alive, so they must not be mixed with pesticides, fertilizers, and peracids and overbased substances during storage, and should not be mixed with large amounts of chemical fertilizers or acid-alkaline fertilizers. Alkali or drought affects the exertion of bacterial fertilizer.
