bacterial fertilizer, commonly known as microbial fertilizer material , is a kind of auxiliary fertilizer with living bacteria. Soil contains a large number of microorganisms (including bacteria, fungi, actinomycetes), typically hundreds of millions to billions of microorganisms per gram of soil. Some are beneficial to the growth and development of crops, while others are harmful.

People use scientific methods to separate and screen beneficial microorganisms from the soil. After the cultivation, reproduction and preparation of microbial agents, these microbial agents are used in agriculture to increase crop yield, which is called bacterial 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 role of fertilizer is as follows.

1. Improve soil nutrient supply . Bacterial fertilizer mainly promotes the dissolution and release of insoluble nutrients in the soil through various microbial agents. Bacteria released a large number of inorganic and organic acidic substances in the process of metabolism, which promoted the release and chelation of trace elements such as silicon, aluminum, iron, magnesium and molybdenum in the soil, effectively broke the soil sheet, promoted the formation of particle structure, transformed the ineffective fertilizer fixed in the soil into effective fertilizer, and improved the supply of nutrients, ventilation and porosity in the soil.

2. Promote crop growth . The use of bacterial manure can promote the production of stimulants, regulate and promote the growth and development of crops. The use of bacterial agents can promote the production of active substances such as gibberellin and auxin.

3. Enhance crop resistance to disease and stress . Some strains of bacterial fertilizer have the function of secreting antibiotics and various active enzymes, inhibiting or killing pathogenic fungi and bacteria; a large number of field experiments have proved that the application of bacterial fertilizer can reduce the occurrence of diseases and insect pests and enhance the resistance of crops.

4. Improve crop quality . The use of microbial fertilizer can increase the content of vitamin C, amino acids and sugars in agricultural products, effectively reduce the nitrate content, and make the produced agricultural products delicious, beautiful and sell at a good price.

Bacterial fertilizer Matters needing attention in use:

(1) Bacterial fertilizer is an active bacterium, which must be buried in the soil when applied, but cannot be spread on the ground. General deep application 7~10cm.

(2) Since biological bacteria will not cause any damage to the root system and seeds of crops, bacterial fertilizer should be applied as close as possible to the root system of crops to maximize contact with the root system of crops to give full play to the fertilizer effect of biological bacterial fertilizer.

(3) as a seed fertilizer, applied 2~3cm below the seed;

(4) It is better to be as close to the root system as possible when topdressing;

(5) When spraying liquid inoculum on the leaf surface, it should be carried out after 3 pm and sprayed on the back of the leaf surface to prevent ultraviolet rays from killing the bacteria.

(6) Soil with high sulfur content and rusty rice fields should not be applied with bacterial fertilizer, because sulfur can kill biological bacteria.

(7) Bio-bacterial fertilizer is best applied 7-10 days before the critical period of nutrition and the period of nutrient absorption.

(8) Do not mix bacterial fertilizer with fungicides, pesticides, herbicides, sulfur-containing fertilizers (such as potassium sulfate, etc.).) And plant ash, because these drugs and fertilizers are easy to kill biological bacteria. Or apply bacterial fertilizer first, and then weed after 48 hours. If seed dressing is carried out, it should not be mixed with seeds mixed with fungicides. Do not mix with unripe farm manure. Good effect of combined application of bacterial fertilizer and organic fertilizer
