摘　　要：本试验将有机复混肥应用于水稻栽培 ,测定产量、产量构成、食用安全性等指标。研究表明 ,施用该有机复混肥对产量的贡献与施化肥相近 ,施有机复混肥处理有效穗数高过施化肥处理 ,其结实率、每穗实粒数少于化肥处理。施用该有机复混肥不会造成糙米As、Cd含量超标 ,试验中不施肥处理降低了糙米中Cd和As的含量。Studies on the effects of the application of organic-chemical mixed and fermented fertilizer (OCMFF) on the yield, yield formation and rice diet safety were carried out. The main results of this OCMFF were summarized as follows: Yield of the OCMFF was close to that of the chemical fertilizer application (CFA) treatment; No matter in the early or in the late season, effective panicle number of the OCMFF treatment was higher than that of the CFA treatment. However, the yield of OCMFF was not able to make a further increase because of the compensation of its lower full grain percentage, lower 1000-grain weight, and lower full grain number.There was no effective impact on diet safety for all applications.
