| 摘 要： | 严重的生理落果会造成山葡萄产量及品质的下降。山葡萄花期之前采取疏花、摘心、喷施叶面肥及植物生长调节剂等调控措施,对提高山葡萄坐果有明显的促进作用。结果表明,花前留6片叶摘心、喷施0.2%硼酸和人工减掉花序长度的1/5,落果率分别为55.33%、47.96%和50.84%,均显著低于对照。

| Abstract: | Serious physiological fruit drop would cause the decline of yield and quality of Vitis amurensis Rupr. The control measures such as flower thinning,different leaves pinching of bearing branches,foliar fertilizer and plant growth regulator had obvious promoting effect on fruit setting. The results showed that reducing 1/5 of inflorescence length before flowering,retain 6 leaves pinching and spraying 0.2% boric acid which the rate of fruitdropping was 55.33%,47.96% and 50.84% respectively were helpful to reduce the fruit drop of Vitis amurensis Rupr. |
