摘　　要：田间试验结果表明:控释氮肥与普通氮肥配合施用,可以增加水稻产量和提高水稻氮肥利用率。50%控释氮肥+50%普通氮肥处理不仅获得了最高产量,而且氮肥利用率也最大。其产量比普通尿素单独施用处理增产375 kg/hm2,利用率比普通尿素单独施用处理提高7.7%。Results of field experiment showed that combined application of release-controlled fertilizer and common fertilizer increased rice yield and improved fertilizer utilization rate.The treatment with 50% release-controlled N＋ 50% common N not only got the highest yield,but also achieved the highest N utilization rate.Rice yield and N utilization rate increased by 375kg/ha and 7.7% respectively compared with the treatment of 100% common N.
