果树盛果初期和果树到了小年,花量少,产量低,经济效益差。为使果树“小年不小”,花少产量高,植物激素就是果树的最好助力。 植物激素具有用药量少,成本低,生理效应范围广,发挥作用快,在植物中易分解,对环境污染轻,能克服果树大小年,提高果品质量,增加贮运性等作用。可提高果树坐果率的激素有:赤霉素、矮壮素、整形素、2,4-D(二氯苯氧乙 Early fruiting fruit trees and fruit trees to a small year, less flower, low yield, poor economic efficiency. In order to make the fruit tree “small is not small,” flowers less yield, plant hormones is the best help of fruit trees. Plant hormones with less dosage, low cost, a wide range of physiological effects, play a role in the rapid decomposition of plants, the light pollution to the environment, to overcome the size of fruit trees, improve fruit quality, increase storage and transportation and so on. Hormones that can increase the fruit set rate of fruit trees are: gibberellin, chlormequat, steroids, 2,4-D
