摘要
Abstract
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 12 685.2 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 15 589.0 yuan·hm-2,which increased by 1 115.4 yuan·hm-2 compared with that of T3 treatment.The yield of T5 treatment was 12 114.6 kg·hm-2,which increased by 471.6 kg·hm-2 and 4.1%compared with T2 treatment,and the net benefit was 15 823.4 yuan·hm-2,which increased by 1 037.3 yuan·hm-2 compared with T2 treatment.The yield of T4 treatment was 11 117.0 kg·hm-2,which was 635.0 kg·hm-2 or 6.1%higher than that of T1 treatment,and the net benefit was 10 873.1 yuan·hm-2,which was 1 397.0 yuan·hm-2 higher than that of T1 treatment.The yield of T8 treatment was 11 913.5 kg·hm-2,which was 168.5 kg·hm-2,or 1.4%higher than that of T7 treatment,and the net benefit was 13 892.8 yuan·hm-2,which was 371.8 yuan·hm-2 higher than that of T7 treatment.关键词
