紫云英配施不同量化肥对水稻产量及经济效益的影响
Effects of Combined Application of Astragalus sinicus with Different Amount of Chemical Fertilizer on Rice Yield and Economic Efficiency
摘要
Abstract
A field experiment was carried out at Xinyang in 2008-2010 to study the effect of combined application of Astragalus sinicus with different amount of chemical fertilizer on rice growth,yield and economic efficiency.The experiment included six treatments:no fertilizer (CK),only application of chemical fertilizer(OACF),combined application of Astragalus sinicus manure (ASM,22 500 kg/ha) with 100％,80％,60％ or 40％ of locally traditional chemical fertilizer.Results showed that the yield of combined application of ASM with 60％ chemical fertilizer was the highest in 2008,9 540 kg/ha,increased by 18.2％ compared with CK;the second was ASM with 80％ chemical fertilizer,9 315 kg/ha,increased by 15.4％ compared with CK.In the year of 2009,the yield of combined application of ASM with 80％ chemical fertilizer was the highest,9424.5 kg/ha,increased significantly by 39.6％ compared with CK.In the year of 2010,the yield of combined application of ASM with 100％ chemical fertilizer was the highest,and the second was ASM with 80％ chemical fertilizer.The net income was higher under combined application of ASM with 80 ％,60 ％ and 40 ％ chemical fertilizer than OACF and CK.From the view point of rice yield,net income,ratio of outputs to inputs and the environment,the combined application of ASM at 22 500 kg/ha with 60％ chemical fertilizer should be optimal in Xinyang.关键词
