Microbial fertilizer is a biologically active fertilizer. The application method is stricter than chemical fertilizers and organic fertilizers. It is necessary to pay attention to the conditions of use and strictly follow the instructions. Otherwise, it is difficult to obtain good results.
1. Microbial fertilizers require strict soil conditions. Microbial fertilizers generally have active activities when the soil temperature is between 18 °C and 25 °C. When the temperature is below 15 °C, the activity begins to decrease. When the temperature is below 10 °C, the activity is weak and even in a dormant state. Therefore, microbial fertilizers use attention to soil temperature and soil moisture.
2. Pay attention to the fertilization period. After the microbial fertilizer is applied to the soil, the microorganism needs a process of adaptation, growth, feeding and reproduction, which usually works after 15 days. If applied, it is applied before the nutrient critical period of the crop. The application time is suitable in the morning and evening or no rainy days, so as to avoid ultraviolet rays in the sun to kill the microorganisms. Avoid use under high temperature and drought conditions.
3. Microbial fertilizers should not be soaked in water for a long time, and should be applied to dry and wet irrigation in paddy fields to promote microbial activities. Products that are mainly aerobic microorganisms should not be used in paddy fields.
4. Microbial agents have a good effect on the basis of applying organic fertilizer. If the supply of organic matter in the soil is sufficient, the microorganisms in the microbial agent will multiply and inhibit harmful bacteria. On the contrary, microorganisms will die due to lack of food. Therefore, organic fertilizer must be applied before crops are planted.
5. Microbial fertilizers can be used alone or in combination with other fertilizers. However, microbial fertilizers should be avoided in combination with unfertilized farmyard manure, otherwise the microbes produced by the fermentation of farmyard manure will kill the microorganisms and affect the fertilizer efficiency. In addition, avoid mixing with peracid, over-alkali fertilizers.
6. Avoid using with pesticides at the same time. Chemical pesticides can inhibit the growth and reproduction of microorganisms to varying degrees, and even kill microorganisms. Do not mix microbial fertilizers with fungicides, insecticides, herbicides, and sulfur-containing fertilizers (such as potassium sulfate) and grass ash. Microbial fertilizers are not used in tools that have been mixed with insecticides and fungicides.
7. Microbial fertilizers should not be placed for a long time. It should be applied in time after unpacking, pay attention to the product shelf life.
