环剥技术在苹果生产上应用较多,它能控制果树过旺生长,对促进果树的花芽分化,保花保果,增加果实膨大有明显作用,特别是对红富士苹果,搞好环剥能大量成花结果,一旦停止环剥,花量明显减少,连年环剥会导致树势衰弱,环剥搞不好还会造成死树现象,因此,广大果农必须准确掌握环剥技术。 环剥技术的应用要根据树龄、树势、品种特点和生产的要求,确定环剥的时间、部位和方法,以做到恰到好处,达到增产增收的目的。 一、环剥时间的确定 1.春季在芽萌动后到初花期进行环剥,能够对苹果落花严重的品种起到保花作用;盛花期环剥能提高苹果座果
Girdling technology is widely used in the production of apples, it can control the overgrowth of fruit trees, and has a significant role in promoting flower bud differentiation, flower preserving and fruit enlargement, and increasing fruit enlargement, especially for red Fuji apples. A large number of flowering results, once the ring to stop peeling, flower significantly reduced perennial pendulum will lead to weakness, poor circumcision will result in dead trees, therefore, the majority of farmers must grasp the girdling technology. The application of girdling technology should be based on age, tree potential, variety characteristics and production requirements, to determine the time, location and method of girdling, so as to achieve just the right to achieve the purpose of increasing production and income. First, the determination of girdling time 1. Sprouting in spring buds to the first flowering ring girdling, can play a protective role of the apple falling serious varieties; flowering pendulum can improve apple fruit
