通过对常见几种果树摘心研究,初步摸清了摘心对果树生长、结果及果实品质的影响。现将摘心在果树上的应用技术总结如下。 1.利用摘心加快果树成形 对桃主、侧枝的延长新梢留40～50cm摘心,时间以摘心部位的二次枝长至10cm以上时最佳,以增加分枝数量,降低分枝部位,并可加强二次枝的生长发育,迅速扩冠,形成丰产树形。对苹果幼树,为培养中央干和主枝,在6月中下旬,对其余新梢摘心可促成形。对李树,当背上和背 Through the study of several kinds of common topping in fruit trees, the influence of topping on the growth, fruit and fruit quality of fruit trees was found. The application of technology in the fruit tree is now summarized as follows. 1. The use of topping to speed up fruit tree formation on the main peach, extension of the side branches to stay 40 ~ 50cm topping, the time to take the place of the second branch topping more than 10cm when the best to increase the number of branches to reduce the branches and Secondary branches can enhance the growth and development, rapid expansion crown, the formation of high yield tree. On young apple trees, in order to cultivate the central stem and main branch, in the middle and late June, the other branches can be indented. To Li Shu, when back and back
