Types and requirements for microbial fertilizers
Microbial fertilizer refers to a specific product containing living microorganisms. Apply it to agricultural production to get a specific fertilizer supply. He and the micro-fertilizer have essential differences, the former is a living life, the latter is a mineral element.
Microbial fertilizers can be summarized into three categories: one is through the life activities of microorganisms, increasing the supply of nutrients in plants, leading to an improvement in the nutritional status of plants. The life of microorganisms antagonizes each other in the soil and harmful microorganisms, and can also produce disease resistance, disease prevention, and even pest control. The dosage is about 2 kg per mu. Representative products of this class are rhizobium, nitrogen-fixing bacteria, phosphate-dissolving bacteria and silicate bacteria (potassium bacteria). The other is microbial metabolic substances, such as amino acids, phytic acid, etc., which are combined with mineral trace elements to produce liquid or solid products to stimulate crop growth or fight pests and diseases. About 100 grams of grain per mu is used. The other type is the function of decomposing organic matter by microorganisms. For example, fermentation or enzyme bacteria accelerate the decay of farmyard manure or straw, and increase the humus of soil. This category is a number of chemical fertilizers to ensure the nutritional needs of crops. The market is called multi-organic fertilizer. Such as "EM" beneficial bacteria. The dosage per mu is more than 1000 kg.
Microbial fertilizer can be used for seed dressing, soaking seeds, roots, base fertilizer, top dressing, ditch application or acupoint application. However, seed dressing is the easiest, more economical and effective. The seed dressing method is to adjust the solid bacterial fertilizer with water to a paste or liquid microbial agent and dilute with water, and then fully stir with the seeds, dry and thickly sow, and immediately cover the soil. Some bacterial fertilizers can also be used as a base fertilizer together with chemical fertilizers.
Microbial fertilizers are biologically active fertilizers and therefore have specific fertilization requirements. First, avoid long-term use after opening the bag. After opening the bag for a long time, the other may invade the bag, causing the microbial flora to change and affect its use effect. The second is to avoid use under high temperature and drought conditions. Under high temperature and drought conditions, survival and vice versa will be affected and will not play a good role. This type of fertilizer should be used in the evening or in the sweet evening, and combined with the cover soil and manure tax, etc., to prevent the microbial fertilizer from being exposed to direct sunlight or due to insufficient water. The third is to avoid mixing with the farmer's fertilizer for decomposing. Such fertilizers are piled up or mixed with decomposed organic fertilizers, which kill microorganisms due to high temperatures and affect the exertion of microbial fertilizers. Also be careful to avoid mixing with over-acid and fertilizer. The fourth is to avoid using it with pesticides. Chemical pesticides inhibit the growth of microorganisms to varying degrees and vice versa. If you need to use pesticides, you should also stagger the use time. It is not possible to use microbial fertilizers with seeds of insecticides and fungicides.
