摘要
为研究微生物菌肥对水稻产量的影响,实验以常规施化肥为对照,设置3个处理,分别为化肥减施10%配施微生物菌肥450 kg/hm2、化肥减施20%配施微生物菌肥650 kg/hm2、化肥减施30%配施微生物菌肥750 kg/hm2。实验结果表明,微生物菌肥能显著增加水稻穗粒数、结实率、千粒重和产量,随着生物菌肥用量的增加,水稻生理性状呈先升高后降低趋势。综合考虑,适当减施化肥并配施微生物菌肥可以显著提高水稻产量和经济效益,其中以化肥减施20%并配施650kg/hm2的微生物菌肥的处理效果最佳。
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/hm2of microbial fertilizer showing the best effect.
