近年来,许多地区建立了矮化密植苹果园.根据我县几年来从事矮化密植栽培的实践,我们认为有以下几方面的好处:1.节约土地:乔化稀植,1亩地栽树10～20株,单位面积产量低.矮化栽培适合密植,每亩可栽树44～111株.便于集约化栽培和机械化管理.2.早结果、早丰产:李店公社肖炉大队,用M_7做中间砧,上面嫁接锦红苹果树接穗,2年见花,3年生幼树花株率83.7%,亩产273斤.4年生亩产830斤;比乔化砧园产量高4倍.嫁接在M_9矮化中间砧上的国光,3年生幼树开花株率63.6%,而乔化国光植株没有开花.复州八里庄
In recent years, dwarf and densely populated apple orchards have been established in many areas. According to the practices of dwarf and dense planting cultivation in our county for several years, we think the following benefits are obtained: 1. Land conservation: 10 ~ 20 plants, low yield per unit area.Dwarfing cultivation is suitable for close planting, planting 44 ~ 111 plants per acre.It is convenient for intensive cultivation and mechanization management.2.As a result, early yield, M_7 as an anvil, the grafted Kam red apple tree scion, 2 years to see flowers, 3-year-old sapling rate of 83.7%, 273 kg per mu. 4-year yield of 830 kg per mu; Guoguang grafted on dwarfing middle stump M_9, the flowering rate of 3-year-old saplings was 63.6%, while Qiaohua Guoguang plants did not flowering.
