摘　　要：为了进一步探讨缓控释氮肥一次性基施的应用效果,以宁夏灌区利通区、平罗县、同心县的露地玉米,南部山区原州区、彭阳县、西吉县的覆膜玉米为研究对象,重点对不同释放期组合型缓控释尿素(释放期分别为45、60、90、120、150 d)及释放期为150 d的缓控释尿素不同施肥量一次性基施施用方法(撒施后旋耕或行侧沟施)进行研究。结果表明:处理T6产量为12685.2 kg·hm^(-2),较处理T3增产507.6 kg·hm^(-2),增产4.2%,净收益为15589.0元·hm^(-2),较处理T3增加1115.4元·hm^(-2);处理T5产量为12114.6 kg·hm^(-2),与处理T2相比增产471.6 kg·hm^(-2),增产4.1%,净收益为15823.4元·hm^(-2),较处理T2增加1037.3元·hm^(-2);处理T4产量为11117.0 kg·hm^(-2),较处理T1增产635.0 kg·hm^(-2),增产6.1%,净收益为10873.1元·hm^(-2),较处理T1增加1397.0元·hm^(-2);处理T8产量为11913.5 kg·hm^(-2),较处理T7增产168.2 kg·hm^(-2),增产1.4%,净收益为13892.8元·hm^(-2),较处理T7增加371.8元·hm^(-2)。In order to further explore the application effect of one-time base application of slow and controlled release nitrogen fertilizer,open field corn in Litong District,Pingluo County and Tongxin County in Ningxia irrigation area and mulched corn in Yuanzhou District,Pengyang County and Xiji County in southern mountainous area were taken as the research objects,the methods of one-time base application(rotary tillage after application or lateral ditch application)of combined slow and controlled release urea with different release periods(45,60,90,120,150 d,respectively)and slow and controlled releaseurea with release period of 150 d were studied.The results showed that the yield of T6 treatment was 12685.2 kg·hm^(-2),and which increased by 507.6 kg·hm^(-2),and 4.2%compared with that of the T3 treatment,and the net benefit was 15589.0 yuan·hm^(-2),which increased by 1115.4 yuan·hm^(-2)compared with that of T3 treatment.The yield of T5 treatment was 12114.6 kg·hm^(-2),which increased by 471.6 kg·hm^(-2)and 4.1%compared with T2 treatment,and the net benefit was 15823.4 yuan·hm^(-2),which increased by 1037.3 yuan·hm^(-2)compared with T2 treatment.The yield of T4 treatment was 11117.0 kg·hm^(-2),which was 635.0 kg·hm^(-2)or 6.1%higher than that of T1 treatment,and the net benefit was 10873.1 yuan·hm^(-2),which was 1397.0 yuan·hm^(-2)higher than that of T1 treatment.The yield of T8 treatment was 11913.5 kg·hm^(-2),which was 168.5 kg·hm^(-2),or 1.4%higher than that of T7 treatment,and the net benefit was 13892.8 yuan·hm^(-2),which was 371.8 yuan·hm^(-2)higher than that of T7 treatment.
