辽宁省苹果树整形修剪技术措施,每年都有程度不同的改进。现针对一九八○年苹果生产实际和展望八一年情况,特提出一九八○年冬苹果树整形修剪技术意见如下: 苹果树整形修剪技术,是在良好的土肥水等综合管理基础上,调节苹果树生长与结果,改善通风透光条件,达到高产稳产优质的重要途径之一,但近年来由于肥水不足。在修剪技术上,各地又对留枝密度,光照程度的看法不甚一致,表现在修剪程度上及修剪方法上轻重不一,粗细不同,严重的造成一些果园的树势渐弱,产量不稳。“大小年”结果现象严重,特别是果品质量下降,小果量普遍增多,果实着色差等,这是当前辽宁省果树整形修剪上存在的主要问题。
Liaoning Province, apple tree trimming technical measures, each year to varying degrees of improvement. In view of the reality of the 1980’s production of apple and the outlook for the year 1981, we hereby put forward the following suggestion on the plastic cutting technology of the winter apple tree in 1980: The apple tree trimming technology is based on the comprehensive management of good soil, fertilizer and water , Adjust the apple tree growth and results, improve ventilation and light conditions, to achieve high yield and quality of an important way, but in recent years due to inadequate fertilizer and water. In the pruning technique, the opinions on the density of remaining leaves and the degree of illumination are not the same everywhere, showing the different degrees of pruning and pruning methods, the different thicknesses and serious decay of some orchards and the unstable yield . “Year of the Year” results in serious phenomena, especially the decline in the quality of fruit, the general increase in small fruit size, fruit coloring and other poor, which is the current Liaoning province fruit tree pruning exist the main problems.
