控制苹果树的生长高度,为苹果管理中的一项重要措施,特别对于乔砧密植树形显得非常重要,因树体高度如大于行距则会加重果园荫蔽程度,影响光合作用,降低光合效率,花芽分化差,果实生长发育都将受到直接影响。以往控制苹果树生长高度时,常采用回缩修剪落头法,要完成落头过程需2—3年,同时,应用不当时,常会出现冒条现象。近年我们试验应用以拉代剪的落头法。取得了令人满意的效果。
Control of apple tree growth height is an important measure in apple management, especially for Joe angels tree planting is very important because the height of the tree body such as greater than the row will increase the shade of the orchard, affecting photosynthesis and reduce photosynthetic efficiency, Poor flower bud differentiation, fruit growth and development will be directly affected. In the past to control the height of the apple tree growth, often using retractable pruning method, to complete the process of falling from 2-3 years, at the same time, improper use, often appear to take the phenomenon. In recent years, we test the application of pull-cut shear method. Achieved satisfactory results.
