笔者在农村从事栟柑技术指导中发现:目前,桔农对栟柑幼年树夏、秋梢修剪整形时,普遍采用“剪平头”(将树顶部剪成一平面)的方法。通过实地观察和调查分析,采用“剪平头”的方法有以下弊端。 一是挂果迟,投入大 通过对80户栟柑开发户调查,4年开始挂果的有6户,大部分5年才开始挂果。与正常修剪方法相比,推迟结果1～2年。4年开始挂果树也是在化肥、农药、用工等投入较多的条件下实现的。 二是枝条多、细、弱,座果率低 由于采用平剪,健壮主枝修剪过重,伤口大,造成同一芽节抽生多条梢;周围弱枝、细枝修剪过轻或未剪,枝梢细而向外扩散,
In the rural areas, the author found that: At present, orange peasants commonly use the method of “cutting the top of a tree” (cutting the top of a tree into a flat surface) when pruning the young trees and the autumn shoots of young orange trees. Through field observation and investigation and analysis, the use of “cut” the following drawbacks. First, the fruit is late, put into a large 80 households through the orange developer survey, 4 years began fruiting 6, most of them began fruiting five years. Compared with the normal pruning method, postponed the results of 1 to 2 years. 4-year-old fruit tree is also started in the fertilizer, pesticides, labor and other inputs to achieve more conditions. Second, the branches more, thin, weak, low fruit set fruit due to the use of flat shear, sturdy main branch pruning, wounds, resulting in the same Bud Festival multiple shoots; around the weak branches, thin branches trim light or not cut , Shoots thin and outward spread,
