Abstract
Two hybrid rice varieties(Zhongzheyou 1 and Yongyou 9) were used in this experiment to study the effect of microbial fertilizer on yield and nitrogen use efficiency of rice.The results showed that yields of two varieties at same nitrogen rate were increased by 4.1% and 8.7% with microbial fertilizer application and without microbial fertilizer application,respectively.The yield increase was associated with increases in panicle per square meter,grain filling rate and grain weight.However,productive tiller percentage was decreased.At panicle initiation and heading stage,the plants which received microbial fertilizer had higher leaf net photosynthethic rate than that of control,the improvement of dry matter accumulation was also microbial fertilizer observed at heading stage.Our results suggested that nitrogen agronomy efficiency and yield of rice were improved,and there is a gradual increase in nitrogen use efficiency with reduction of nitrogen application.
