摘要 通过施用硅钙肥与常规施肥以及八五四农场当地硅肥做对比试验,研究硅钙肥在八五四农场水稻上的应用效果。结果表明,与常规施肥相比,硅钙肥与常规硅肥分别增产19.4、10.9 kg/667 m2,增产3.28%、1.84%,硅钙肥处理比常规硅肥增产8.5 kg/667 m2,增产1.42%。从效益分析来看,硅钙肥处理和常规硅肥处理在单位面积收益、净增效益方面高于常规施肥处理。与常规施肥相比,分别比当地常规施肥增加效益38.6元和18.7元/667 m2;硅钙肥处理比常规硅肥处理增效益19.9元/667 m2。 Contrast test between Si-Ca fertilizer and general chemical fertilizer were made to research the application effect on rice. The result indicated that compare with general chemical fertilizer, Si-Ca fertilizer and conventional Si fertilizer can increase yield by 19.4 kg/667 m2,10.9 kg/667 m2, and its yield-increase rate was 3.28% and 1.84%, Si-Ca fertilizer can increase yield by 8.5 kg/667 m2 and yield-increase rate by 1.42% than conventional Si fertilizer. The income and net profit by using Si-Ca fertilizer and conventional Si fertilizer was higher than general chemical fertilizer which was 38.6 yuan and 18.7 yuan]667 mE, Si-Ca fertilizer can increase income by 19.9 yuan/667 m2 than conventional Si fertilizer.
