整形修剪是获得花椒高产的重要技术之一。合理整形修剪能使树体骨架坚固,层次分明,枝条健壮,配备合理,光照充足,通风良好。修剪培育过的花椒树长势旺,果穗大,色艳、味浓、产量高,又可以延长树的寿命。 一、修剪原则 主枝要少,小枝要多。主枝3～5个,小枝为结果枝,枝组和侧枝分布要均匀合理。 二、修剪时间 修剪时间由树势强弱而定。幼枝、旺树在秋季采果后修剪为宜,弱树、老树待春天发芽后修剪为好。 三、树形 一般采用自然开心形、丛状形、三角形3种。 1.自然开心形:定植后定干高约30厘米,当年培养留4～5个主枝,基角45～60度,每条主枝留侧枝2～3个,结果枝组均匀分布。4～5年完成树形,最后去掉中心枝,开膛即可。
Trimming is one of the important techniques for obtaining high yield of pepper. Reasonable plastic trim can make the tree skeleton solid, structured, robust branches, equipped with a reasonable, adequate light, good ventilation. Pruning cultivated pepper growing vigorously, big ears, color Yan, strong flavor, high yield, but also can extend the life of the tree. First, the main principle of pruning less, twigs and more. 3 to 5 main branches, branchlets as a result branches, branch groups and side branches should be evenly distributed. Second, pruning time Pruning time by the strength of the tree may be. Young shoots, polonium trees in the autumn picking fruit pruning appropriate, weak trees, old trees to be spring pruning after pruning as well. Third, the tree generally use natural happy shape, plexiform, triangular 3 kinds. 1. Natural happy heart shape: set dry after about 30 cm tall, then cultivate to stay 4 to 5 main branches, 45 to 60 degrees base angle, each side of the main branch stay 2 to 3, the results Zhizu uniform distribution. 4 to 5 years to complete the tree, and finally remove the center branches, can be opened.
