摘　　要：通过田间试验,探讨了不同用量控释尿素对冬小麦农艺状况、产量和氮肥利用率的影响。结果表明:等氮量控释尿素处理下的冬小麦农艺性状多数优于普通尿素处理,尿素施用量减少30%以后也能达到普通尿素100%用量的产量水平,且氮肥利用率显著提高。运用控释肥可以实现一次性施肥,既能节约用工成本,又能提高小麦产量和氮肥利用率,应用前景广阔。The effects of controlled-release urea on the agronomic characters,yield and nitrogen use efficiency of wheat were studied by field experiment.The results showed that the agronomic characters of controlled-release urea were better than that of normal urea with equal nitrogen amount.When N was at the level of 180 kg/ hm2,the yield of wheat could reach the level with normal urea amount,and the nitrogen use efficiency increased significantly.The application of controlled-release urea could save labor cast,increase the yield and nitrogen use efficiency,which had a broad application prospect.
