桃幼树萌芽率高,成枝力强,枝条生长快,易生竞争枝、徒长枝和副梢枝,极易造成冠内密闭,影响通风透光,加重枝条向强弱两极分化,造成弱枝枯死。因此,通过夏季修剪调节,控制无效枝叶,培养良好的树体结构和优良高效的结果枝组,是极为重要的栽培措施。 一、抹芽 当萌芽后的新梢长到5～15厘米时,采取抹芽来调节新梢密度、部位和延长头的发枝方向及增加树势。具体方法:1.对立枝延长头剪口芽为三芽梢,抹两边留中间强旺梢;主枝延长头剪口芽为双芽梢时抹弱留强;若主枝需要分头时可利用留双芽梢的办法分头。2.对树体其
Young shoots of peach trees have high germination rate, strong branching ability, fast growth of branches, easy competition of branches, leggy branches and branchlets, which can easily lead to the confinement inside and outside of the crown and affect the ventilation and light penetration, increase the polarization of the branches to weakness and weakness, Death. Therefore, through the summer pruning regulation, control invalid leaves, cultivate good tree structure and excellent and efficient results Zhizu, is an extremely important cultivation measures. First, wiping bud When the bud after the shoot grow to 5 to 15 cm, to take wipes to adjust the density of shoots, parts and extend the head hair direction and increase the tree potential. Specific methods: 1. Opposite branches to extend the first scotch buds for the three shoots, wiping both sides stay in the middle of the strong shoots; main branch extension of the scissors buds for the double shoots wipe strong stay strong; if the main branch needs to be split when available Stay buds way to split. 2. The tree body
