摘　　要：以两系超级杂交稻88s/0293为试材,通过田间小区试验研究了包膜控释尿素对其产量和氮肥利用率的影响。结果表明,树脂包膜控释尿素处理比普通尿素处理显著提高了水稻产量和氮肥利用率。氮肥用量为180 kg/hm2时,树脂包膜控释尿素与普通尿素按1∶1掺混基施处理水稻增产效果最好。氮肥用量减少30%时,树脂包膜控释尿素基施处理氮肥利用率比其他处理高5.0~23.0个百分点。With two-line super hybrid rice 88s/0293 as tested material,the effect of controlled release coated urea on its yield and nitrogen（N） utilization rate was researched through field plot experiment.The results indicated that compared with common urea,controlled release resin-coated urea enhanced the yield and N utilization rate of rice significantly.When the N dosage was 180 kg/hm2,in the treatment of fertilizing mixed urea with proportion of 1∶1 of controlled release resin-coated urea to common urea as base fertilizer,the effect of increasing rice yield was best.When the N dosage was reduced by 30%,compared with other treatments,the N utilization rate of treatment with fertilization of controlled release resin-coated urea as base fertilizer was increased by 5.0%-23.0%.
