In the consciousness of many fruit farmers, the soil is composed of organic matter such as soil, dead branches and leaves, various nitrogen, phosphorus and potassium nutrients and water. But in fact, the emergence of soil is the emergence of microorganisms on the earth, microorganisms decompose stones (ores) into elements that can be used by plants, and decompose organic matter (carcasses and feces of animals and plants) into organic matter that can be used by plant roots, and soil is produced. With soil, there is an environment for the growth of animals and plants and a circulating medium, and decomposing organic matter is used by plants.
Microorganisms make all decay, including dead branches and leaves in the soil, animal carcasses, organic fertilizer, are dependent on the role of soil microorganisms to make the organic matter in the soil decay and decompose, into nutrients for crop consumption, the formation of humus, so that the soil is more nutritious and healthier.
So, what role do microbes play in citrus groves? Let's take a look.
1. Increase production
Practice has proved that microbial bacterial fertilizer not only provides nutrients for crops, but also its effective bacteria can secrete active substances such as gibberellin, cytokinin, auxin, etc., stimulating, regulating and promoting the growth and development of crops, which is conducive to increasing crop yields.
2. Improve quality
Microbial bacterial fertilizer can effectively improve the quality of agricultural products. Practice has proved that the citrus harvested with microbial fertilizer water has significantly improved the content of beneficial ingredients such as sugar, vitamins and amino acids, and the grains and fruits are plump and smooth, and the fruits are bright in color, which is both delicious and good-looking, and the value is still high. Microbial bacterial fertilizers can also reduce the accumulation of nitrate and improve the safety of agricultural products.
3. Enhance the stress resistance of crops
Most of the effective bacteria in the microbial bacterial fertilizer have the function of secreting antibiotic substances and a variety of active enzymes, which can inhibit or kill pathogenic bacteria, reduce the occurrence of diseases and enhance the resistance of crops to stress, such as enhancing the drought resistance, cold tolerance, lodging resistance, disease prevention and salinity resistance of crops, while also effectively preventing the occurrence of physiological diseases of crops.
4. Improve the utilization rate of chemical fertilizers
Most of the effective bacteria of microbial bacterial fertilizer can decompose organic matter in the soil, and humic acid is generated during the decomposition of organic matter, and humic acid forms ammonium humic acid with nitrogen in the soil, which can reduce the loss of nitrogen fertilizer. Potassium-soluble phosphorus effective bacteria can decompose the solidified chemical potassium fertilizer and chemical phosphorus fertilizer in the soil into available potassium and available phosphorus, improve its utilization rate, reduce production input, and reduce resource waste.
5. Improve soil nutrients
Microbial bacterial fertilizer effective bacteria can promote the dissolution and release of refractory nutrients in the soil, and improve the supply capacity of soil nutrients. The extracellular polysaccharide substances secreted by effective bacteria are the binders of soil aggregate structure, which can enhance soil aggregate structure, loosen soil, improve soil permeability and water retention and fertilizer retention capacity, increase soil organic matter, activate potential nutrients in soil, and improve the supply of nutrients in soil.
