目前,许多苹果幼树存在着适龄不结果和低产问题,应用主干环状剥皮技术,虽能缓势促花,但也出现有死树现象,红星品种死树更甚,可达35％左右。为此,我们近年来做了苹果幼树的“主干双环三方剥皮”试验,此方法对促花、控冠效果明显,未发现死树现象。具体做法是在环剥适期,距地面30～50cm处, At present, many young apple trees have the problems of age-less fruitlessness and low-yielding. The application of the trunk ring-shaped peeling technique can promote flower blossoms in a slow manner, but there is also a dead tree phenomenon. To this end, we have done in recent years, apple tree “trunk double ring trilateral skinning” test, this method to promote flowers, crown control effect is obvious, no dead tree was not found. Specific approach is to cycle in the right period, from the ground 30 ~ 50cm,
