近年来,我省苹果发展很快,不少果园已开始挂果,进入初果期。此期应根据其自身特点和要求,正确运用修剪技术,以达到既长树又结果的目的。 苹果树在前4—5年(幼树期)主要是增枝长树,整形扩冠,开角缓势,夏剪促花。6年生以后,进入结果期,由增枝作形向结果转化,因此,修剪的内容较多,比较复杂,既要清理过多的临时枝完善树形,打开光路,又要培养枝组,调整枝势,力争早果早丰。但此时树性极不稳定,修剪稍重就易返旺,延迟结果,所以修剪难度较大。为搞好初果期苹果树的转化修剪,应做好以下工作。
In recent years, the rapid development of apple in our province, many orchards have begun to fruiting, into the early fruiting period. This period should be based on its own characteristics and requirements, the proper use of pruning technology, in order to achieve the purpose of both trees and results. Apple trees in the first 4-5 years (sapling) is mainly by the growth of branches and trees, plastic expansion crown, open angle relief, summer cut flower. After 6 years of age, it will enter into the result period, which will be converted from the result of increasing branches to the result. Therefore, the content of pruning is more and more complex. It is necessary to clean up excess temporary branches, perfect the tree shape, open the light path, Branches, and strive to early fruit abundance. But this time the tree is very unstable, easy to return a little trimming Wang, delay the results, so more difficult to trim. In order to do a good job in the first trimming of the apple tree transformation, should do the following work.
