2. Main functions:
2.1. It can chelate soil nutrients, stimulate root growth, make crops grow steadily and vigorously, with high fertilizer utilization and remarkable yield.
2.2. Improve the photosynthetic performance of crops, the transfer and transportation of photosynthetic products, and improve the quality of crops and their commercial properties.
2.3. It can improve the micro-domain environment of crop rhizosphere, inhibit the occurrence of soil-borne diseases, and has obvious effect of resisting crop stubble.
2.4. Combined application with inorganic fertilizer can increase the synergistic effect of nutrients, and the effect of increasing crop yield is remarkable.
2.5. Long-term application can make the soil porous and loose, reduce the degree of soil compaction, and improve the soil's ability to retain fertilizer and water.
