多效唑对金柿产量及生长发育的影响

Effect of Paclobutrazol(pp333) on the Production and Growth of Persimmon Jinshi

[目的]探讨柿树矮化密植、早果丰产技术。[方法]于柿树生长期喷施不同浓度的多效唑(pp333),分析多效唑对金柿产量及生长发育的影响。[结果]叶面喷施多效唑对金柿平均单株产量、坐果率、果枝率、成枝率均有显著影响。多效唑可极显著地抑制其营养生长,促进坐果,提高产量。其中以800 mg/kg处理浓度效果最佳。[结论]喷施浓度800 mg/kg多效唑可以有效抑制金柿营养生长,提高产量。

[Objective] The aim was to explore the persimmon tree dwarfing close planting, early-fruitting and high-yielding technology. [Method] Effect of paclobutrazol （pp333） on production and growth of persimmon was analyzed, by spraying paclobutrazol with different concentration on persimmon tree in growth period. [Resultl The results showed that foliar spraying paclobutrazol had significant effect on individual yield, fruit setting rate, fruit-setting branch rate, branching rate of persimmon Jinshi. Paclobutrazo｜ could significantly inhibit vegetative growth, promote fruit setting, increasing production. With 800 mg/kg concentration effect was best. [Conclusionl Spraying paclobutrazol with 800 mg/kg concentration could effectively restrain the vegetative growth and improve the production of persinnnon.
