摘　　要：采用大田试验,对"水冬瓜果油"包膜尿素与土壤水分耦合效应进行研究。结果表明:在相同灌水量和肥料施用量情况下,施包膜尿素比普通尿素可以推迟叶绿素SPAD下降时间40 d,平均产量增加为12.7 t/hm2。平均水分利用率可提高3.4 kg/hm2·mm,其中灌水2 600 m3/hm2,施包膜氮肥150 kg/hm2,增产最高,包膜尿素与水耦合效果最好。The field experiment was carried out and the effect of coupling coated urea and water on growth of sugarcane was studied, the result showed when the same irrigation water and fertilizer were used, the chlorophyll SPAD of coated urea application was delay 40 d than that of the normal urea and that of the average yield was increased to 12.7 t/hm2 and the effect of water use efficiency was improved 3.4 kg/hm2/mm. The treatment（the irrigation 26 00 m3/hm2 and coated ureal50 kg/hm2）was the highest yield and the effect of coupling coated urea and water was the best.
