What are the functions and effects of the correct use method and time of microbial fertilizer

1. The method of using biological fertilizer correctly and timely

1. How to use

(1) Topdressing with base fertilizer: Use 1-2kg of biological bacterial fertilizer per mu, mix evenly with farmyard manure and chemical fertilizer, and then apply in furrows, holes, and spread.

(2) Furrow application: if it is a young tree, apply it in a circular furrow, with an amount of about 200g per plant; if it is an adult tree, apply it in a radial furrow, with an amount of about 0.5-1kg per plant (mixed with fertilizer or soil).

(3) Dipping the roots to irrigate the roots: Use 1-2 kg of biological fertilizer per mu, dilute 3-4 times with water, dip the roots when transplanting, or irrigate the roots at other periods after planting.

(4) Stir the seedbed soil: Mix the seedbed soil with 200-300g of biological fertilizer per square meter evenly before sowing.

(5) Potted plants: Use 10-15g of biological bacterial fertilizer per kilogram of potting soil as top dressing or base fertilizer.

(6) Fertilization: Mix 1-2kg of biological fertilizer and chemical fertilizer per mu evenly, dilute with water and then flush with water.

2. Use time

Biological bacterial fertilizer is generally used in spring and autumn, and it is better to use it when the temperature is more suitable. The specific use time depends on the growth of the crops.

What are the functions and functions of biological fertilizer?

1. There are many beneficial microorganisms in the biological bacterial fertilizer, which can greatly increase the nutrient content in the soil, thereby reducing the application of chemical fertilizers, and at the same time can increase soil organic matter, accelerate the degradation rate of soil organic matter, and convert it into the nutrients needed by crops .

2. Improve the soil structure, inhibit fungi, nematodes and plant root diseases and insect pests in the soil, thereby reducing the use of pesticides.

3. Biological bacterial fertilizer can promote the growth of crop root system, make the crop root system more developed, enhance the absorption capacity of crops, and thus improve the disease resistance of crops.

4. After the use of biological bacterial fertilizer, the pollution of pesticides and chemical fertilizers to crops is reduced, and the quality of crops is improved.
