In 1960s and 1970s, people put too much emphasis on pruning technology, thinking that "a pair of scissors can change everything". There was a heated debate among the factions. After decades of production practice, it has gradually formed the understanding that light pruning and long release are beneficial to increase production and improve quality. At present, in order to further simplify the traditional pruning techniques in the past, we have summarized eight basic pruning methods suitable for high quality, high efficiency and easy learning for reference and application in production.
Eight basic pruning methods of apple trees: high quality and high efficiency, simple and easy to learn. Generally speaking, branches and trunk extension branches are basically not cut, except for saplings, which need to cut off trunk extension branches in order to expand the crown and cultivation population in the years after planting, because "short is the enemy of early fruit". In addition, small and medium-sized crowns are now advocated. The heavier the tree is cut, the stronger the tree, the faster the crown expands and the later the flowering and fruiting. So few people advocate cutting expenses. Shortcuts are few, which is not only stable, but also labor-saving and easy to blossom and bear fruit. Basically, it will not recover unless the branches are too long and the trees are extremely weak. General branches, including main branches and auxiliary branches, basically do not use the method of cutting. Shrinking and shearing can strengthen and promote local areas, with many contractions, easy strips and dense crowns.
Eight basic pruning methods of apple trees: high quality, high efficiency, simple and easy to learn, used for small corners of main branches, back corners of side branches and outer branches. Because there is no push from the puller, it is common for the new tip to tilt upward again or even open at a smaller angle than the original tip. In order to effectively control and transform the auxiliary branch, the large branch group can also shrink behind the good branch. However, this practice should not be excessive, and the number of branches recovered should not exceed 1/6. In most cases, in order to solve the problem of crown closure, it is better to use thinning instead of pruning, and the effect is better. Basically, from the young tree stage, the pruning method of light cutting and long putting is adopted, and the auxiliary branches and branches are basically long putting. When using the trunk form, if the branches are tall and strong, they should not be cut, stand upright and continue to extend uniaxial, and draw an ideal 3-5 in the center of their complete buds. The expansion of the outer branches is not competitive, or even competitive. It is very necessary to train a strong center.
