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氮水平对晚稻生长、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、7236．95kg／hm^2，与常规氮肥处理（7095．21kg／hm^2）相比，增加了1．17％、1．76％和1．99％，差异均不显著俾〉0．05），15％纳米膨润土包膜氮肥不减氮时产量为7270．30k...

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...
