摘　　要：为探讨包膜肥料在葡萄上的应用效果,通过田间施用包膜肥料,研究包膜专用肥料对巨峰葡萄光合特性和产量品质的影响。结果表明:施用包膜肥料可改善巨峰葡萄叶片的光合特性,提高葡萄产量和品质。包膜肥料的施用降低了葡萄叶片的气孔导度与蒸腾速率,以包膜加抑制剂比常规施肥减量20%处理效果最好,比对照和NPK常规施肥分别增产35.41%和10.52%;施用包膜肥料后葡萄的糖酸比变化不大,而Vc含量显著高于常规施肥处理。Effects of coated fertilizer on the photosynthetic properties, yield and quality of Kyoho grapes were studied in field experiment in 2005. The results showed that applying coated fertilizer could improve the photosynthetic properties, increase the yield and improve the quality of Kyoho grapes, and decrease stomatal conductance and transpiration rate of grape leaves. The application of coated fertilizer plus inhibitor under the condition of 20% decrement of the routine rate had yield increments about 35.41% and 10.52% compared with the control and routine NPK application respectively. Using coated fertilizer had little effect on sugar-acid ratio of fruit, but could increase vitamin C content significantly.
