加查园艺一场共有13年生苹果树3500株,一九七七年总产18万斤,一九七八年预计总产将超过35万斤以上,今年比去年增产一倍左右。该场苹果品种以黄元帅、青香蕉、国光等为主要栽培品种。对果树的修剪采用了疏直留斜(即疏去直立枝)、连年短截、以截为主的修剪方法,取得了较好的效果。具体做法是:对一年生发育枝,枝枝短截,发枝促花(下部2—3个花芽),使结果部位下移;在多年生部位上以短果枝结果为主,基本不用长果枝,促进发枝生花,强势结果,结果部位多在2—3年枝以上,腋花芽结果数量不多。一般的大枝不多,树体分为丽层,光照由挖去中心头开天窗的办法解决;枝组密度较大,平均每公尺长有枝组9—10个;由于树体层数少,大枝疏,光照较好,
A survey of gardening A total of 13-year-old apple tree 3500, with a total output of 180000 kilograms in 1977, is expected in 1978 the total output will exceed 350000 pounds, more than doubled this year than last year. The apple varieties to Marshal Huang, green banana, Guoguang as the main cultivars. The pruning of fruit trees used to sparse stay ramp (ie, to sparse upright branches), successive years of short cut to cut the main method of pruning, and achieved good results. The specific approach is: the annual growth of branches, branches short cut, hair and flower (lower 2-3 flower buds), so that the results of the site down; perennial parts in the main results of short branches, the basic need for long branches, and promote Streaked flowers, strong results, the results of more than 2 - 3 years in the branches above the axillary buds results in small quantities. General large branches, the tree is divided into layers, the light by digging to open the center of the sun roof way to solve; Zhizu density, with an average length of 9-10 branch group; due to the tree layer is small, Big branch sparse, light is better,
