近几年来,我国北方各省试用毛樱桃做矮化砧木,培育出的矮化桃苗,栽植后具有早花早果、成熟早、品质好等特点,适于密植,便于管理,经济效益高。其栽培管理措施如下:(1)适度密植.矮化桃树冠矮小,单位面积内株数可适当加多,据河南内黄县农家的经验,亩栽133株,2年生桃园亩产500公斤,3年生亩产2000公斤。经济效益大大超过乔砧桃园。矮化桃还可以在阳台、平台或屋顶上客土栽培。(2)整形修剪.主要树形有自然开心形与自然杯状形。矮化桃多采用自然开心形。干高20—30厘米,主干上错落排列3个主枝,各按30°—45°开张角向外延伸,每个主枝上选留3—4个侧枝,开张角60°—80°。桃树修剪分休眠期修剪(冬剪)和生长期修剪(夏
In recent years, our country’s northern provinces try to make dwarfing rootstock of cherry, dwarfing peach cultivated, with early flowering early after planting, early maturity, good quality and so on, suitable for close planting, easy to manage, high economic efficiency. The cultivation and management measures are as follows: (1) Moderately dense planting. Dwarf peach crown short, the number of units per unit area may be appropriate to increase, according to Henan Huang county farmers experience, planted acres of 133 acres, 2 years Taoyuan yield 500 kg, 3 Annual per mu 2000 kg. Economic benefits greatly exceeded Joe anvil Taoyuan. Dwarf peach can also be cultivated on the balcony, platform or roof. (2) Trimming and shaping. The main tree has natural happy and natural goblet shape. Dwarf peach more natural happy shape. Dry high 20-30 cm, the main trunk of the three main branches scattered arrangement, each opening angle of 30 ° -45 ° outward extension of each branch on the election left 3-4 branches, opening angle 60 ° -80 °. Peach pruning sub-dormancy pruning (winter shear) and growth pruning (summer
