Application technology of soybean rhizobium

Published: 2024-11-22 Author: mysheen
Last Updated: 2024/11/22, The use of rhizobium in soybean production is a mature and widely used technology, which can greatly improve the nitrogen fixation ability of soybean during the growing period and supply sufficient nitrogen for soybean production. Soybean rhizobium has two dosage forms: liquid and solid. Solid rhizobium was applied by seed dressing or soil application. Liquid rhizobium was used by soaking seeds. Soybean rhizobium agent can also be added when seed coating, but it should be noted that the coating agent and rhizobium agent should match each other, and the activity of rhizobium should not be inhibited because of the effect of seed coating agent. one

The use of rhizobium in soybean production is a mature and widely used technology, which can greatly improve the nitrogen fixation ability of soybean during the growing period and supply sufficient nitrogen for soybean production.

Soybean rhizobium agent can also be added when seed coating, but it should be noted that the coating agent and rhizobium agent should match each other, and the activity of rhizobium should not be inhibited because of the effect of seed coating agent.

I. increasing production and increasing efficiency

According to the results of field demonstration, the application of rhizobium in soybean can increase soybean yield by more than 10%, increase soybean protein content by 2%, increase crude fat content by 1%, and increase net income by 40,50 yuan per mu.

II. Technical points

The main results are as follows: 1. Select suitable soybean rhizobium varieties to collect the main soil types in soybean production area, carry out soil and rhizobium matching test, and screen soybean rhizobium varieties with strong activity, good effect and adaptation to local soil and climate.

2. According to the dosage form of soybean rhizobium, the solid bacteria were mixed or granulated with soybean seeds and fertilizers, and the liquid bacteria were used.

It is used by soaking seeds. Soybean rhizobium agent can also be added when seed coating, but it should be noted that the coating agent and rhizobium agent should match each other, and the activity of rhizobium can not be inhibited because of the effect of seed coating agent.

3. The reasonable dosage of bacterial agent is 0.5 kg per mu when seed dressing, 1: 2 kg per mu after seed granulation, 0.5 kg per mu when soaking seeds with liquid bacterial agent, and 0.5 kg per mu when seed coating is according to the requirements of seed coating agent.

Soybean rhizobium is a living microbial preparation, in the process of storage, transportation and use, the temperature should not be too high or too low; at the same time, it should not be mixed with fungicides.

III. Suitable area and scope

Soybean rhizobium can be widely used in Heilongjiang, Jilin, Liaoning, Inner Mongolia and Huang-Huai-Hai soybean producing areas in China. From 2002 to 2004, it was demonstrated and extended to 8 million mu in soybean production areas of Liaoning, Jilin, Heilongjiang and Inner Mongolia, with good results and broad application prospects.
