当软枣猕猴桃新梢长至３０～３５ｃｍ时，叶面喷布一次２０００～４０００ｍｇ／Ｌ或喷布二次３０００ｍｇ／Ｌ的ＰＰ３３３，可显著地降低新梢长度、增加中短枝比例，抑制生长的效应可延续到翌年；并可显著地增加花芽数量，花芽量随喷布浓度的加大呈增加趋势。３０００ｍｇ／Ｌ一次处理不影响果实大小，二次处理则使果实变小。ＰＰ３３３对果实糖酸含量无明显影响，但可增加Ｖ－Ｃ含量。分析叶片４种内源激素（赤霉素、吲哚乙酸、玉米素、脱落酸）含量的动态变化表明，由于ＰＰ３３３的参与，使赤霉素、玉米素含量显著下降，吲哚乙酸、脱落酸含量显著上升，这是抑制生长和促进花芽分化的主要内在因素。
When jujube shoots grow up to 30-35 cm, foliar spraying 2000-4000 mg / L or spraying twice 3000 mg / L PP333 can significantly reduce the shoot length, increase the ratio of shoots, inhibit growth The effect can be extended to the following year; and can significantly increase the number of flower buds, flower bud volume increases with the spray concentration increases. 3000mg / L a treatment does not affect the size of the fruit, the second treatment is to make the fruit smaller. PP333 had no significant effect on the sugar and acid content of fruit, but increased V-C content. The dynamic changes of the contents of four endogenous hormones (GA, indole acetic acid, zeatin, abscisic acid) in leaves showed that the content of gibberellin and zeatin decreased significantly due to the involvement of PP333. The contents of indole acetic acid, abscisic acid Content increased significantly, which is to inhibit growth and promote flower bud differentiation of the main internal factors.
