修剪是果树栽培管理的一项重要技术措施。在加强其他管理的基础上,正确的修剪,可有效地调节与控制果树的生长与结果状况,达到结果早、产量高、品质好,树命长的目的。果树修剪技术的基础在于对树体生长发育规律及其对修剪反应的深刻了解。为了给制定合理的修剪技术措施提供依据,前几年,我们以国光品种为试材,进行了一些修剪反应方面的研究工作,最近又作了一些调查,兹将调查 Pruning is an important technical measure for fruit tree cultivation and management. On the basis of strengthening other management, proper pruning can effectively regulate and control the growth and fruiting status of fruit trees, achieving the goal of early fruiting, high yield, good quality and long life of tree. Fruit tree pruning technology is based on the law of growth and development of the tree and its deep understanding of the pruning reaction. In order to provide a basis for the development of reasonable pruning techniques and measures, a few years ago, we used Guoguang varieties as materials to carry out some researches on pruning reactions and recently conducted some surveys. We will investigate
