一、整形修剪花椒树的整形修剪,应掌握低杆(30厘米)矮冠、枝条疏散、开心的原则,留主枝5—7个,在主枝背下、两侧直接配备结果枝组。幼树应尽量多留校条,栽后二、三年基本不去枝,枝多叶多,扩冠迅速,缓和树势,促进营养积累,缩短树的幼龄期。幼树轻剪,目的在于早期多建新枝,提高叶片功能,促使由营养生长向生殖生长转化。花椒树一般不短截,只做些撑、拉、曲、别等工作。主枝开张以40—50°为宜,其余枝条要为永久枝让路。利用生长季节回缩部分临时枝,应与休眠期培养永久枝结合进行。
First, the plastic pruning pruning plastic tree pruning, should grasp the low pole (30 cm) dwarf crown, branches evacuated, happy principle, leaving the main branch 5-7, in the main branches of the back, both sides directly with the results Zhizu group. Young trees should be as long as possible to retain the school, planted two or three years after the basic does not sticks, branches and more leaves, crown expansion rapidly, ease the tree vigor, promote nutrient accumulation, shortening the young age of the tree. Saplings cut, the purpose is to build more new branches in the early to improve leaf function, prompting the growth by the vegetative growth and transformation. Pepper generally not short cut, only to do some support, pull, song, do not wait for work. Main branch opened to 40-50 ° is appropriate, the remaining branches to give way for the permanent branch. Using the growth season to retract part of the temporary branch, should be incubated with permanent branch dormancy combined.
