Microbial fertilizer refers to a specific product containing active microorganisms. Apply it to agricultural production to obtain a specific fertilizer supply. There is an essential difference between him and micro-fertilizer. The former is a living life, and the latter is a mineral element.
Microbial fertilizers can be summarized into three categories. One is to increase the supply of functional nutrient elements through the life activities of microorganisms, resulting in improved nutritional status. Microbial fertilizers antagonize each other in the soil and harmful microorganisms, and can also produce disease-resistant, disease-resistant, and even insect-control effects. The amount of fertilizer is about 2 kg per mu. This type of representative products are rhizobia, nitrogen-fixing bacteria, phosphorus-solubilizing bacteria and silicate bacteria (potassium bacteria). The other is the metabolites of microorganisms, such as amino acids, yellow phytic acid, etc., and it is combined with mineral trace elements to make a liquid or solid product, which can stimulate the jihad and resist pests and diseases of crops. Amount of land per mu is about 100 grams. Another type is the use of microorganisms to decompose the function of organic matter, such as fermentation or enzyme bacteria, to accelerate the decay of farmyard manure or straw, to increase the role of soil humus. In this category, more chemical fertilizers are added to ensure the nutritional requirements of the crops. The market is called multiple organic fertilizer. Such as "em beneficial bacteria.
Microbial fertilizers can be used for seed dressing, soaking, rooting, rooting, top dressing, furrowing, or hole application. However, seed dressing is the most convenient, economical and effective method. The seed dressing method is to first adjust the solid bacterial fertilizer with clear water to a paste or a liquid bacterial agent and add water to dilute, and then stir well with the neutron, dry it slightly, then sow, and immediately cover the soil. Some fungus fertilizers can also be mixed with fertilizers as base fertilizers.
Microbial fertilizers are bioactive fertilizers and therefore have specific application requirements. The first is to avoid long-term use after opening the bag. After opening the bag for a long period of time, other bacteria may invade the bag, causing the microbial flora to change and affecting its use. The second is to avoid use under conditions of high temperature and drought. Under high temperature and drought conditions, survival and reproduction will be affected and they will not play a good role. The use of such fertilizers should be selected on a cloudy or sunny evening, combined with cover soil, manure, watering, etc., to prevent microbial fertilizers from being exposed to direct sunlight or due to insufficient water. The third is to avoid mixing with unripe farmyard fertilizers. The stacking or mixing of these fertilizers with uncomplexed organic fertilizers will kill microorganisms due to high temperatures and affect the exertion of microbial fertilizers. At the same time, care must be taken to avoid mixing with over-acid and over-alkaline fertilizers. The fourth is to avoid simultaneous use with pesticides. Chemical pesticides inhibit the growth and reproduction of microorganisms to varying degrees, and even kill microorganisms. If you need to use pesticides, you should also stagger the use of time. Do not mix microbial fertilizers with tools that contain pesticides and fungicides.
