| 摘 要： | [目的]评价控释尿素在新疆哈密瓜上的应用效果.[方法]通过2年田间试验,研究施N量为0、189、270 kg/hm2的控释尿素和普通尿素对新疆哈密瓜产量、品质和养分吸收的影响.[结果]控释尿素增加了哈密瓜的单株瓜数和单瓜重,增加产量5.89;～22.20;,同一氮肥品种的哈密瓜产量与施氮量呈正相关；哈密瓜的还原糖、VC和可溶性固形物含量均表现为控释尿素处理大于等氮量的尿素.2年中还原糖含量平均提高了18.9;和8.1;；同时控释尿素提高了植株对氮、磷、钾养分的吸收,氮肥表观利用率平均提高了12.20;,吸磷量提高15.43;,吸钾量增加38.65;,哈密瓜养分吸收比例为N∶ P2O3∶ K2O=1∶ 0.48∶1.18.[结论]控释尿素处理能明显提高哈密瓜的产量、品质和养分吸收量.
