摘　　要：为确定山垅田中稻氮肥最佳施用量,指导同类型耕地中稻科学施肥,采用随机区组试验,在磷钾肥相同基础上,以不施氮肥为对照,设置5个施氮肥处理,研究各处理对优质中稻隆两优黄莉占农艺性状和产量的影响。结果表明,在复垦山垅田种植隆两优黄莉占,4个施氮肥处理的产量均极显著高于不施氮肥处理,但氮肥施用量每667m^(2)达到10 kg以上时,稻谷产量并未随施氮量的增加而相应提高;不施氮肥处理的产值低于成本,4个施氮肥处理每667m^(2)可获得纯收益227.4~321.8元。说明施用氮肥对复垦山垅田中稻的增产效应极显著,但最佳施氮量有待进一步试验确定。A randomized block experiment was conducted to investigate the effects of different nitrogen application on agronomic traits and yield of Longliangyouhuanglizhan,and to clear the optimum nitrogen rate for scientific fertilizer application of medium rice in volley paddy field.Results showed that nitrogen application increased yield compared to the control,and there was not significant difference during nitrogen application treatments.The grain output value of control was lower than its input cost,nitrogen application treatments gain a net income of 227.4-321.8 RMB.Thus,nitrogen application can increase yield of medium rice in reclaimed land,and the optimum amount nitrogen need further research.
