Effect of New Microbial Fertilizer on Main Agronomic Characters of Rice
[Objective]The aim was to explore the effect of new microbial fertilizer on the main agronomic characters of rice in northern Hebei.[Method]The new microbial fertilizer,organic fertilizer,cow manure and sheep manure were used as the base fertilizer to spread,and each fertilizer was set up with 5 kinds of fertilizer amounts,with no fertilization as the control.The effects of different fertilizers and amounts on the main agronomic characters of rice were compared,and the relationship between different agronomic characters and fertilizer types and fertilizer amounts was investigated.[Result]The results showed that the plant height,stem diameter and leaf number of rice treated with 11.25 t/hm2 microbial fertilizer were good,the effective tillering rate was 99.90%,the yield was 7 740.09 kg/hm2,and the main agronomic characters and yield of rice were significantly improved.[Conclusion]This study provided theoretical basis and technical support for the application of microbial fertilizer in high-yield and high-quality cultivation of rice in northern Hebei.
