采用大田试验,研究了不同比例纳米膨润土包膜氮肥及不同施氨水平对晚稻生长、产量和氮素利用率的影响.结果表明:施用纳米膨润土包膜氮肥处理的产量、千粒重、穗粒数等均显著高于空白处理(CK),其中施用氮肥处理比CK处理的产量高出21.53％～28.01％ (P＜ 0.05),不同施氮水平下施用纳米膨润土包膜氮肥对晚稻产量差异有影响,10％纳米膨润土包膜氮肥在不减氮、减氮20％及减氮30％时,产量分别为7178.54、7220.28、7236.95 kg/hm2,与常规氮肥处理(7095.21 kg/hm2)相比,增加了1.17％、1.76％和1.99％,差异均不显著(P＞0.05),15％纳米膨润土包膜氮肥不减氮时产量为7270.30 kg/hm2,增加2.47％(P＞ 0.05),减...

A field experiment was conducted to study the effect of different proportions of nano-bentonite coated nitrogen fertilizer and N application levels on growth, yield and nitrogen utilization efficiency （NUE） of late rice. The results showed that the yield, 1000 grain weight and grain number per spike of nano-bentonite coated nitrogen fertilizer treatment were significantly higher than those of CK. Compared with CK, the yield of N application treatment increased by 21.53% to 28.01% （P〈0.05）. The effect of nano-bentonite coated nitrogen ferti...
