| 摘 要： | 为了避开不利气象因素,促进张家界地区石榴开花结果,以突尼斯软籽石榴为材料,分别于头年夏季、春季萌芽期、春季展叶期对结果树进行了多效唑喷施试验。结果表明:喷施多效唑可以抑制突尼斯软籽石榴的营养生长;在春季展叶时喷施对增加枝梢径粗、缩短枝长和延后花期的效果最好;多效唑降低了突尼斯软籽石榴的坐果率,但能提高植株完全花数量达1~3倍,因此喷施多效唑仍能提高树体的坐果数量。

| Abstract: | Experiments of paclobutrazol spraying were conducted on "Tunisiruanzi" pomegranate in three different periods. The results showed that paclobutrazol inhibited the vegetative growth of "Tunisiruanzi" in Zhangjiajie of Hunan Province. It had the best effects on stem-diameter increase, branch-length decrease and flowering delay when paclobutrazol spraying was carried on in the spring leaf-expansion period. Paclobutrazol reduced the fruit setting rate, but it can improve the quantity of perfect flowers by 1-3 times. In brief, the application of paclobutrazol increased fruit yield of "Tunisiruanzi" in Zhangjiajie. |
