以凤稻19号为供试材料,通过大田试验研究氮肥运筹方式对水稻的影响。结果表明,凤稻19号处理D(2.5:2.5:2.5:2.5)产量达11720kg/hm2,极显著高于对照A(4:4:1:1),增产幅度为16.79%;C处理(3:3:2:2)产量达11430kg/hm2,极显著高于对照处理,增产幅度为13.9%。本研究认为,在高海拔稻区氮肥运筹应以均衡或接近均衡的配置方式施肥能使产量和氮肥利用率得到提高。 Taking Fengdao 19 as tested material, the effects of nitrogenous fertilizer operation mode on rice were studied through field experiment. The results showed that the yield of F20 was significantly higher than that of control A (4: 4: 1: 1) and the yield was 16.79%. The yield of F (2.5: 2.5: 2.5: : 3: 2: 2) The yield reached 11430kg / hm2, which was significantly higher than that of the control and the yield was 13.9%. This study suggests that nitrogen fertilization in high altitude rice paddy should be balanced or close to the balanced allocation of fertilization can make the yield and nitrogen fertilizer utilization rate is improved.
