The Impact of Microbial Fertilizer on Rice Yield and Economic Benefits
This study aims to explore the impact of microbial fertilizer on rice yield.The experiment used conventional chemical fertilizer application as a control and set up three treatment groups,which were a 10%reduction in chemical fertilizer combined with 450 kg/hm2 of microbial fertilizer,a 20%reduction in chemical fertilizer combined with 650 kg/hm2 of microbial fertilizer,and a 30%reduction in chemical fertilizer combined with 750 kg/hm2 of microbial fertilizer.The results showed that microbial fertilizer significantly increased the number of grains per panicle,seed setting rate,thousand grain weight,and yield of rice,with an increasing trend at first and then decreasing.Properly reducing the application of chemical fertilizer and applying microbial fertilizer can significantly improve the yield and economic benefits of rice,with the treatment of reducing chemical fertilizer by 20%and applying 650 kg/hm2 of microbial fertilizer showing the best effect.
