苹果树的修剪对果品的产量、质量及经济效益有很大的影响。因此,合理的修剪方法是提高果品的商品性和市场竞争力的重要措施。 苹果树“三套枝”修剪法就是在修剪过程中,有意识地培养一套结果枝,一套营养枝,一套预备枝。一套结果枝,用于苹果树当年开花结果;一套营养枝,用于制造营养,供生长结果用,同时也增加树体贮备营养;一套预备枝,用于形成花芽,准备下一年结果。这三套枝的作用不是固定不变的,而是每年轮换。 在苹果树冬季修剪时,运用三套枝修剪法可连续稳产、高产。具体作法是:选留一部分果枝,用于当年开花结果;缓放一部分枝条,使其当年形成花芽;短截一部分营养枝,促生分枝,增加枝叶量,第二年形成花芽,用于第三年结果。
Apple tree pruning on the fruit yield, quality and economic benefits have a great impact. Therefore, a reasonable pruning method is an important measure to improve the commerciality and market competitiveness of fruit products. Apple tree “three sets of” pruning method is pruning process, consciously cultivate a set of results branches, a set of vegetative branches, a set of preparatory branches. A set of fruiting branches for the flowering of the apple tree; a set of vegetative branches for the production of nutrients for the production of growth results, while also increasing the reserve of the tree; a set of pre-branches for the formation of flower buds for the next year result. The role of these three sets of branches is not fixed, but the annual rotation. In the winter pruning of apple trees, the use of three sets of pruning method can be continuous and stable yield, high yield. The specific practice is: Select part of the fruit branch for the flowering results; relieve some of the branches, so that the formation of flower buds the same year; short cut part of the nutrition branch, promote branch production, increase the amount of branches and leaves, the formation of flower buds the second year, Three year result.
