1. Affect the growth of some above-ground vegetative bodies. On the basis of sufficient nutrient supply, peptides and enzymes secreted by biological fungi can stimulate the growth of some aboveground vegetative bodies of crop plants, which are manifested in plant height and stem thickness.
2. Factors affecting output and composition. Biological inoculants have an impact on crop yield and constituent factors. They can increase the production of food crops with more ears and more grains. The early stage has a good effect on tillering and reducing the empty rate.
3. Affect the physiological metabolism and enzyme activities of crops. After the special secretion of biological fungus enters the plant body, it stimulates the plant, which is mainly manifested in the increase of respiratory intensity, the increase of photosynthesis, and the enhancement of the activity of *** enzymes, so that the fruit is colored and matured in advance. , To achieve high yield and high value.
4. Prevent and control plant diseases and insect pests. Biological agents can effectively control underground pests and plant diseases and germs. Biological agents have obvious control and antibacterial effects on fruit tree rot, leaflet, yellow leaf disease, cucumber downy mildew, pepper anthracnose, virus disease, etc.
5. Change the quality of agricultural products. The application of biological inoculants not only has obvious yield-increasing effects and economic benefits, but also is green and environmentally friendly, and can greatly improve the quality of agricultural products. It is an important product of the green industry.
