摘　　要：[目的]研究草酰胺在水稻上的应用效果。[方法]2016年在苏州三地开展缓释肥草酰胺替代传统氮肥一次性施肥试验,分析缓释肥草酰胺一次性施肥对水稻生长性状、土壤性质、产量结构、经济效益的影响。[结果]较常规施肥处理,缓释肥草酰胺一次性施肥对水稻有着明显的增产效果,增产幅度在1.8%~11.2%,且其增产跟水稻有效穗数、每穗实粒数和千粒重有关。草酰胺缓释肥一次性施肥可减少36.8%的氮肥施用量,但达到常规施肥产量,较常规施肥处理增加经济效益486~3 195元/hm2,平均节本增效1 857.0元/hm2。[结论]该研究可为水稻的肥料施用提供参考。[Objective]Application effect of oxamide was researched for rice.[Method]Single fertilization test of oxamide replacing traditional nitrogenous fertilizer was carried out in Kunshan,Taicang and Changshou in2016.Effects of oxamide on growth traits,soil properties,yield structure and economic benefit were analyzed.[Result]compared with conventional fertilizer,single oxamide fertilization had obvious yield-increasing effect,yield-increasing rate was1.8%-11.2%,and yield-increasing was related to effective spike number,grain per spike,1000-grain weight.Single oxamide fertilization can decrease by36.8%nitrogenous dosage,but gain the same yield of conventional fertilizer;Single oxamide fertilization can increase by486-3195yuan/hm2economic benefit,increase income1857.0yuan/hm2.[Conclusion]The research can provide reference for fertilizer application of rice.
