In recent years, more and more vegetable farmers have begun to use microbial fertilizers. However, there are some misunderstandings in the understanding and application of biological bacterial fertilizers. Biological bacterial fertilizers are treated as ordinary fertilizers, regardless of type or application, affecting the application effect. Here, it is recommended that the vegetable farmer choose the right type of fungus fertilizer according to different purposes to achieve better results.
The effect of the fungus fertilizer is determined by the species of the bacteria. So, what are the beneficial microorganisms that we commonly use in bacterial fertilizers and what are their effects?
The most widely used bacterial fertilizer is bacteria. Bacillus in bacteria is an important part of bacterial fertilizers. Bacillus megaterium, Bacillus subtilis, and Bacillus spp. . Bacillus megaterium can be used to produce phosphorus-fixed potassium fertilizer, which has a good effect of degrading organic phosphorus in soil. Bacillus subtilis is mainly used to ferment and ferment various types of organic fertilizer (manure); Bacillus glomerulata is also called silicate bacteria. , It can decompose potassium-containing minerals composed of silicates and aluminosilicates, with phosphorus, potassium release and nitrogen fixation. The bacteria can self-metabolize, produce organic acids, hormones and other substances that are beneficial to plant absorption and utilization, and also inhibit the growth of other pathogenic bacteria.
In addition, the commonly used strains of bacterial fertilizer production include actinomycetes, yeasts, and nitrogen-fixing bacteria. Actinomycetes can synthesize antibiotics that kill harmful bacteria, and their own secretions can promote the growth of vegetable roots; yeasts can be used for the fermentation of organic fertilizers. Nitrogen-fixing bacteria can fix nitrogen in the air, increase soil nutrient levels, and reduce fertilizer use.
The use of bacterial fertilizers is not the same, and the types of biological bacteria chosen are also different. Some are used to decompose organic fertilizers to avoid burning roots, such as high antibacterial 968 fertility; some can produce antibiotics and inhibit harmful bacteria around the rhizosphere , to avoid root disease infection, while enhancing the function of the roots, etc., such as a large source to take root and so on. We should rationally choose biological bacterial fertilizer based on the type of biological bacterial fertilizer.
Many vegetable farmers have incorrectly applied the fungus fertilizer as a conventional fertilizer. It is an auxiliary fertilizer because it does not contain the nutrients needed by the plants. Instead, it uses the life activities of microorganisms to accelerate the transformation of nutrients and promote the development of crops. The absorption of nutrients inhibits the activity of harmful bacteria. Therefore, the fungus must be used in conjunction with the organic fertilizer in order to give full play to its productivity increase.
