Bacterial fertilizer is a fertilizer that contains a large number of beneficial microorganisms and is based on the biochemical action of these microorganisms to improve crop nutrition and growth conditions. Beneficial microorganisms mainly include rhizobium (biological nitrogen fixation), phosphate-dissolving bacteria (insoluble phosphorus in activated soil), potassium-dissolving bacteria, also known as silicate bacteria (decomposition, release of mineral potassium in soil), antibiotics, such as "5406" (It can inhibit or kill harmful fungi and bacteria, stimulate crop growth and activate soil insoluble phosphorus) and enzyme bacteria (to promote organic matter conversion). The actual fertilizer efficiency of the bacterial fertilizer is often also related to the matrix in which the microbial life activities are maintained.
As a agricultural product, biological fertilizer must meet certain quality requirements in terms of viable count, miscellaneous rate and expiration date (NY227-94). In addition to agricultural microbial agents, there are also composite microbial fertilizers and bio-organic fertilizers based on this. Compound microbial fertilizer refers to a combination of specific agricultural microorganisms and nutrients, which can provide, maintain or improve plant nutrition and improve the production or quality of agricultural products. According to the technical standard of NG/T798-2004, the total nutrient (N+P2O5+K2O) content of liquid, powder, granule and other different dosage forms products should not be lower than 4%, 6% and 6%, respectively, but the fertilizer content is not higher. The better, too high will inhibit microbial activity. Bio-organic fertilizer refers to a compound made up of organic materials obtained from harmless and humification of specific agricultural microorganisms and animal and plant wastes. It combines the characteristics of microbial fertilizers and organic fertilizers according to the technical standards of NY884-2004. The organic matter content of the fertilizer shall not be less than 25%.
Microbial fertilizer can be used as base fertilizer, top dressing, ditch application or acupoint application, and can also be used for seed dressing, soaking, rooting or foliar application, depending on the type of fertilizer.
The agricultural fungicide is mixed with 2 kg of solid bacteria and 40-60 kg of decomposed organic fertilizer to make base fertilizer, top dressing or seedling; the solid bacteria and nutrient soil are mixed to make nutrient mash, or mixed with mud slurry, in seedlings Before transplanting, the seeds are immersed in 10~20 times of the microbial dilution or sprayed with the diluent, so that the seeds are fully contacted with the liquid biological bacteria and then sown; the seedlings are immersed in the diluted 10-20 before transplanting the seedlings. The liquid microbial agent is taken out immediately, or the root of the seedling is sprayed with the above dilution solution; the microbial agent is diluted 100 times and used for rooting or flushing; the microbial agent is diluted 500 times for foliar fertilizer.
The compound microbial fertilizer can be used as base fertilizer and top dressing, and the application amount is 10-20 kg per mu; the foliar fertilizer is diluted 500 times, and sprayed according to the requirements of the product specification.
The bio-organic fertilizer can be used as the base fertilizer and top dressing. When the base fertilizer is used as the base fertilizer, the application amount is about 100 kg, and it is best to apply the appropriate amount of farmyard manure; the amount of topdressing fertilizer is appropriately reduced, and the fertilizer is applied 7 to 10 days earlier, and the fertilizer should be applied.
In addition, when the soil nitrogen, phosphorus and potassium nutrient content is high or a large amount of NPK fertilizer is applied, the effects of rhizobium, phosphate-dissolving bacteria and potassium-dissolving bacteria fertilizer are reduced or even inhibited. For example, excessive application of nitrogen fertilizer inhibits rhizobial activity. To reduce the nitrogen fixation of nodules. In addition, it is noted that the beneficial microorganisms in the bacterial fertilizer are alive, so they cannot be mixed with pesticides, chemical fertilizers, peracids and over-alkali substances during storage, and should not be mixed with a large amount of chemical fertilizers or acid-alkaline fertilizers. Alkali or drought affects the effect of bacterial fertilizer.
