摘　　要：目前葡萄栽培管理过程中普遍存在施肥次数过多,施肥量过大等问题,为简化葡萄施肥过程,降低施肥成本;利用田间微区试验,通过长效尿素与磷钾肥配合使用,探讨一次性施肥和简化施肥对巨峰葡萄产量品质的影响。结果表明,长效尿素与磷钾肥一次性施用比有机肥对照和NPK常规施肥分别增产32.4%和8.1%。糖酸比、Vc含量、可溶性固形物含量高于或相似于常规施肥处理;利用长效尿素与普通磷钾肥配合,一次性施肥法在巨峰葡萄上可以应用。In order to simplify the process and to decrease the cost of fertilization, the experiment is to research the response of One-off and simplified applying process of slow-released urea with PK on the yield and qualities of grapes. The result shows that the yield of grape with One-off applying of slow-released urea with PK increased 32.4% and 8.1% compared with organic fertilizer treatment and routine treatment3 （NPK using in 3 times）. The ratio of sugar and acid, the Ve content, the content of soluble solids are higher than or similitude with routine treatment.
