摘要： 以中浙优1号、Y两优900、甬优538和甬优12为材料，研究复合微生物肥对水稻生长及产量的影响。结果表明，在相同施肥成本下，施用复合微生物肥比传统施肥平均增产331.41 kg/hm2，增3.58%，主要是通过增加每穗粒数和每穗实粒数来实现；施用复合微生物肥能提高水稻株高和收获指数，并通过增产实现增效。因此，在水稻生产过程中可通过施用复合微生物肥实现化肥减量目标。

Abstract: The effects of a new compound microbial fertilizer on the growth and yield of rice were studied in this paper, using Zhongzheyou1, YLiangyou 900, Yongyou 538 and Yongyou12 as materials. The results indicated that the average yield was increased by 3.58% using compound microbial fertilizer, compared with traditional fertilization at the same cost, by increasing grains per spike. Compound microbial fertilizer could also increase the height and harvest index of rice. Besides, it could enhance farming efficiency by increasing yield. So, compound microbial fertilizer could contribute to the goal of reducing the application rate of chemical fertilizer in rice production.

Key words: rice, microbial fertilizer, yield, benefit
