长野县是从1972～1973年开始苹果矮化栽培。1979年全县苹果矮化栽培面积已超过1000公顷。在整形上,是以欧洲主要采用的细长纺锤形整枝为基础。然而,由于该种树形荷兰主要用于以 M 9为砧木的金冠上。在日本的苹果品种是以“富士”和“津轻”等为主,其枝条的分枝能力不同,当采用该形整枝时就出现了树形不理想等问题。近几年,长野县果树试验场,利用植物调节剂打破枝条的顶端优势,培养理想树形的试验,取得一定的成果。下面就细长纺锤形整枝的基本方法和利用植物调节剂整枝的改进方法作一简要阐述。采用细长纺锤形整枝,是要造就这样一种树势,即在矮化栽培(行距为3.5～4.5米,株距为1.25～2.5米左右)的情况下,即或有少量枝条互相交叉也无关重要的程度。该树形是以主干形为基
Nagano prefecture began to plant dwarf apple from 1972 to 1973. In 1979 the county dwarf apple cultivation area has more than 1,000 hectares. In plastic surgery, it is based on the slender spindle-shaped pruning that is mainly used in Europe. However, due to this kind of tree, the Netherlands is mainly used for gold crown with M 9 as rootstock. The apple varieties in Japan are mainly “Fuji” and “Tsugaru”, and their branches have different branching ability. When using this type of pruning, the tree shape is not ideal. In recent years, Nagano Prefecture fruit tree test site, the use of plant regulators to break the top edge of the branches, the ideal tree-shaped test, and achieved some results. The following is a brief description of the basic method of slender spindle-shaped pruning and the improved method of using the plant regulator pruning. The use of slender spindle-shaped pruning is to create such a tree potential that in the case of dwarfing cultivation (spacing of 3.5 to 4.5 meters, spacing of 1.25 to 2.5 meters or so), that is, or a small number of branches cross each other has nothing to do Important degree. The tree shape is based on the trunk shape
