该文总结了１９９２～１９９４年在国光苹果上应用多效唑的试验结果。在生长季节叶面喷施６００μｇ／ｇ，在秋季果实采收后到翌年发芽前地下土施，６～８ａ生幼旺树以株施２５ｇ效果最佳。无论采用叶面喷施或地下土施均对促矮成花、早果早丰、提高座果率、增强果实品质、减少夏剪次数等有明显作用。并提出了在国光苹果幼旺树上推广应用多效唑的实施方案。
This paper summarizes the experimental results of application of paclobutrazol to Guoguang apple from 1992 to 1994. In the growing season foliar spraying 600μg / g, after the harvest in the autumn fruit to underground soil before germination the next year, 6 ~ 8a young tree best plant strain 25g. Both foliar application and underground soil application have significant effects on promoting dwarf flowering, early fruiting and early harvest, increasing fruit set rate, enhancing fruit quality and reducing the number of summer cuttings. And put forward the implementation plan of promoting and applying paclobutrazol in Guoguang apple tree.
