Farmers often encounter slow growth of crops, diseases and insect pests. This is caused by too many harmful bacteria in the soil and insufficient nutrition of crops. Faced with this problem, you can use fertilizer to improve. It is necessary for farmers to have a deep understanding of the role and efficacy of bacterial fertilizer . The main function of

bacterial fertilizer is to improve soil activity and supplement crop nutrients, which is embodied in three aspects:

1. Improve soil activity. The beneficial bacteria in can effectively target harmful bacteria in the soil, inhibit the growth of pathogenic bacteria, and reduce the occurrence of crop diseases. 2. Fertilization efficiency is improved. The soil activity of

bacterial fertilizer is enhanced and the root grows, so as to improve the absorption rate of fertilizer and achieve the effect of less application and high efficiency. 3. Improve the growing environment of crops. Rich organic matter can also improve the physical properties of the soil, increase the structure of soil aggregates, so as to loosen the soil, reduce soil compactness, help to retain water and fertilizer, promote root development through air, and provide a suitable micro-ecological growth environment for crops.

When land

is about to collapse , microbial agents are the saviors. In times of crisis, microbial agents have achieved the following: first, to reduce the amount of chemical fertilizer, increase the content of nitrogen in the soil, and reduce the amount of nitrogen fertilizer applied; at the same time, it contains beneficial microorganisms to improve soil fertility and reduce the amount of chemical fertilizer; second, to increase production, improve the quality of crops and agricultural products, and increase farmers' income; third, is to reduce soil phytotoxicity and improve crop resistance to diseases and insect pests; 4. Promote plant growth, improve resistance and lodging resistance.

bacterial fertilizer has some special functions that other fertilizers do not have. First, it can improve the utilization rate of chemical fertilizers, which can not only ensure the increase of production, but also reduce the use and cost of chemical fertilizers, improve the quality of soil and crops, and reduce pollution; secondly, the production of green food requires the use of chemical fertilizers, chemical pesticides and other chemicals as little as possible Substances, bacterial fertilizer can be done. At present, the production and application of bacterial fertilizer in China mainly include rhizobia, nitrogen fixing bacteria, phosphorus bacteria, potassium bacteria and antibiotic fertilizer. Bacterial manure antagonizes harmful microorganisms through the life activities of beneficial microorganisms, promotes the transformation of soil nutrients, improves the effectiveness of soil nutrients, improves the nutritional conditions of crops, and increases soil fertility. The application of bacterial fertilizer includes foliar spraying of bacterial liquid, seed spraying of bacterial liquid, seed dressing, and mixing of solid microbial agents with seeds as bacterial fertilizer.

Inorganic nutrients for plants are ions. Fertilizer is soluble in water and changes from molecular state to ionic state, which is easily absorbed by plants because it has a charge and is conducive to plant adsorption. Organic nutrients are large molecules made up of many atoms that are not easily absorbed. The role of bacterial fertilizer is to convert organic nitrogen, phosphorus and potassium into inorganic state, which is conducive to plant absorption.
