摘要 为探究化肥减量配施有机肥对水稻农艺性状、产量和种植效益的影响。选取“中稻深两优5814”为试验材料,对照组为常规施肥组,试验1、2组分别化肥减量15%、30%,试验3、4组在化肥减量15%、30%基础上每667 m^(2)配施200 kg有机肥。结果表明:与对照组相比,不同试验组成穗率均下降,化肥减量的试验1、2组的结实率分别减少3.21%、3.55%,亩产量减少4.52%、11.11%,化肥减量配施有机肥的3、4组结实率分别提高了3.67%、0.94%,亩产量提高了16.76%、12.05%,种植收益提高了144.24元/667 m^(2)、67.49元/667 m2。综上,化肥减量配施有机肥可以改善水稻农艺性状,提高产量和种植效益。
