Summary
By rational selection and scientific application of biological microbial fertilizers, not only can the amount of chemical fertilizers be reduced and the risk of diseases be lowered, but also the quality and efficiency of agricultural products can be improved.
By rational selection and scientific application of biological microbial fertilizers, not only can the amount of chemical fertilizers be reduced and the risk of diseases be lowered, but also the quality and efficiency of agricultural products can be improved.
In the future, with the innovation of functional strain screening technology (such as CRISPR gene editing) and carrier materials, bio fertilizers will play a more important role in smart agriculture.
1、 Nitrogen fixing bacterial fertilizer
By using nitrogenase, nitrogen in the air is converted into ammonia nitrogen that plants can absorb, reducing fertilizer dependence.
Rhizobium agent: Soybean rhizobia form a symbiotic relationship with leguminous crops, with a nitrogen fixation capacity of 5-15 kilograms per acre, equivalent to 25-75 kilograms of urea.
2、 Phosphate solubilizing bacterial fertilizer
Secreting organic acids (such as citric acid and gluconic acid) to dissolve insoluble phosphorus and improve the utilization rate of phosphorus fertilizer.
Bacillus subtilis (phosphate solubilizing type): In tomato cultivation, the application of organic fertilizer can increase the available phosphorus content in the soil and improve the vitamin C content in the fruit.
3、 Potassium solubilizer fertilizer
destroys the crystal lattice of minerals such as mica and feldspar, releasing potassium elements while secreting plant hormones to promote root development.
Bacillus subtilis: In banana cultivation, the use of potassium solubilizing bacterial fertilizer combined with potassium fertilizer can reduce the amount of potassium fertilizer used, increase banana yield per mu, and increase fruit hardness.
4、 Probiotic fertilizers
inhibit pathogens by competing for nutrients, secreting antibiotics, and inducing plant resistance (such as SAR systems).
Hartz's wood mold: In strawberry greenhouses, the combined application of wood mold and EM bacteria can reduce the incidence of root rot disease, lower the rate of strawberry malformed fruits, and increase the weight of individual fruits.
5、 Compound bacterial fertilizer
forms a functional complementary network consisting of photosynthetic bacteria (carbon fixation), lactic acid bacteria (antibacterial), and yeast (growth promoting).
EM microbial agent: containing more than 80 types of microorganisms such as photosynthetic bacteria, lactic acid bacteria, yeast, etc. When applied in citrus orchards, the soil organic matter content increases and the incidence of citrus canker disease decreases.
What are the advantages of bio fertilizers ranging from 4.35 billion to 2 million tons? How to exert force?
6、 The mycelial network of mycorrhizal fungi
can extend to areas beyond the reach of roots, absorbing nutrients such as phosphorus and zinc, and enhancing drought resistance.
Arbuscular mycorrhizal fungi (AMF): In saline alkali soil experiments, the combination of AMF and organic fertilizer improved cotton emergence rate, increased root length, and increased cotton yield.
