本文报道了利用本所选育的“甜黄魁”做中间砧,以其上嫁接锦红、长红、金冠等品种的砧穗组合为试材,研究了矮化密植园的高产生态指标及其高产栽培技术。三年初步结果表明:通过采用锦红/甜黄魁优良砧穗组合的健壮苗木、改善树体的营养水平、改革修剪技术及使用生长调节剂等栽培技术,有效地缩短了苗木缓苗期,迅速增加幼树分枝级次及总生长点数,改变了枝类组成,使三年生幼树每株总生长点数平均达630个,总生长量达105.7米,叶面积系数达4.4,提高了植株绿色部分对阳光辐射的截获率,积累了营养,促进腋花芽形成。因而在亩栽167株的条件下,获得了一年开花,二年结果,三年亩产3316.68斤的好收成。为辽宁省发展苹果矮化栽培提供了依据。 This paper reports the use of “sweet Huangkui” selected by our institute to make the intermediate anvil, and the scion and root scion combination of the grafted reddish, Its high-yielding cultivation techniques. The preliminary results for three years showed that the seedlings were effectively rejuvenated by using robust seedlings with the combination of fine red angelica rootstocks, improving the nutritional level of trees, reforming pruning techniques and using growth regulators and other cultivation techniques, The number of branches and the total growth points of saplings were rapidly increased, the composition of branches was changed, the average number of growing points per tree of the three-year-old saplings was up to 630, the total growth was 105.7 meters and the leaf area coefficient was 4.4, The green part of the interception rate of solar radiation, accumulated nutrients, promote axillary bud formation. Thus 167 acres planted under the conditions of access to a flowering year, two years results, three-year yield of 3316.68 kg per mu good harvest. It provided the basis for the development of apple dwarfing cultivation in Liaoning Province.
