施用有机复混肥对稻米产量和食用安全性的影响

Effects on the application of organic-chemical mixed and fermentedfertilizer on the yield and diet safety of rice

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。糙米Hg超标表明本研究不同处理都不能有效解决稻米食用安全性问题。

Studies on the effects of the application of organic-chemical mixed and fermented fertilizer (OCMFF) on the yield of rice, yield formation and rice diet safety were carried out. The main results 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.
