幼龄桃树的明显特点是生长旺盛,其二三年生树表现更为突出,往往推迟结果或产量不高。只有控制其旺长,才能实现二年结果,三年丰产。现将技术要点介绍如下: 一、开张角度 加大主枝角度、缓和树势是幼树早果丰产的重要措施。一是采用撑拉坠等办法将主枝角度开张到70度左右。撑拉坠等办法宜在生长前期进行,并注意防止主枝劈裂。二是采取主枝换头开张角度。冬季修剪时选方向角度合适的侧枝或背后枝代替主枝延长;夏剪时及时摘心,然
The obvious characteristics of young peach trees are strong growth, the tree performance in the two or three years more prominent, often postponed the results or yield is not high. Only control its flourishing, in order to achieve the result of two years, three years of high yield. The technical points are as follows: First, the opening angle to increase the main branch point of view, to ease the tree vigor is young trees early fruit yield an important measure. First, the use of bracelets and other ways to pull the main branch angle opened to about 70 degrees. Pull pull and other measures should be carried out in the early growth, and pay attention to prevent the main branch split. The second is to take the main branch exchange opening angle. Winter pruning when the election of the appropriate direction of the side branches or branches instead of the main branch to extend; summer cut time topping,
