1. According to the experiment, the use of chemical fertilizers and organic fertilizers for 3 years is higher than the organic matter content of single-fertilizers by 0.08%-0.11%, ammoniated bacteria by 260%, and aerobic nitrogen-fixing bacteria by 119. %, fiber decomposition bacteria increased by 600%.
2. High-yield and high-quality grain The combination of chemical fertilizer and organic fertilizer can increase the yield by 10%-20% compared with single application of chemical fertilizer in the middle and low-yield land, and the grain quality is also greatly improved.
3. Reducing fertilizer loss Tests have shown that the combination of chemical fertilizer and organic fertilizer can reduce soil redox potential, reduce ammonia nitrification, and reduce nitrogen volatilization loss. Generally, the nitrogen fertilizer utilization rate can be increased by 10% to 15%.
