There are many types of microbial fertilizers commonly found in fruit trees. According to its mechanism of action and influence on plant growth, it can be divided into nitrogen-fixing bacterial fertilizer, phosphate-dissolving bacterial fertilizer, potassium-dissolving bacterial fertilizer, antibiotic bacterial fertilizer and compound bacterial fertilizer. The organic fertilizer manufacturing process mixes and granulates these fungi into high-quality commercial fertilizers.
1. Nitrogen fixing bacteria fertilizer
Nitrogen fixing fertilizer is a kind of fertilizer that uses nitrogen fixing microorganisms to transform nitrogen in the atmosphere into ammonia that can be used for crops. It can increase the nitrogen content in soil, provide necessary nitrogen nutrition for protein synthesis, and promote plant growth. Biological nitrogen fixation can be carried out under normal temperature and pressure, and granulation can be carried out by double roller granulator. Nitrogen fixing fertilizer has also become the most ideal and promising fertilizer.
2. Phosphate solubilizing bacteria fertilizer
Phosphate solubilizing bacterial fertilizer is a kind of fertilizer which can convert the phosphorus which is difficult to be absorbed by plants into available state. This kind of fertilizer can not only activate insoluble phosphorus in soil, but also increase the absorption of potassium, calcium, magnesium, iron, zinc and other nutrients by plant roots, so that plants can adapt to salt, alkali, phosphorus deficiency and other harsh environment.
3. Potassium solubilizing bacteria fertilizer
Potassium silicate fertilizer fungicide is a solution for major bacteria, which can decompose insoluble inorganic minerals silicate and aluminum silicate, release potassium, phosphorus, silicon and other elements, increase soil available nutrients, promote the growth of rhizosphere bacteria, and process with disc granulator to promote the growth and development of crops and increase yield.
4. Antibiotic fertilizer
Antibiotic fertilizer is a kind of microbial fertilizer product, which is made by microorganisms secreting antibiotics and stimulants. Most of its strains are actinomycetes. Antibiotics can compete with pathogens for nutrition, secrete antibiotics, destroy the cell wall of pathogens, inhibit the synthesis and reproduction of some pathogens, and have the effect of disease prevention and seedling protection on crop growth. Stimulants can secrete plant growth regulators such as indoleacetic acid, cytokinin and gibberellin to promote production. Rooting, germination and early maturity.
