Naturally growing fruit trees have closed crowns, dense branches, overlapping, holes, weak tree vigor, poor lighting and ventilation, serious pests and diseases, low yield, easy fruiting in different years and poor fruit quality, which is not convenient for fruit harvesting, flower thinning and pest control.
Only by reasonable pruning can young trees accelerate crown expansion, increase the number of branches, bear fruit ahead of time, and thus enter high yield ahead of time, and pay attention to cultivating tree structure that can make rational use of light energy, achieve high yield and obtain high-quality fruits; Pruning the fruit trees in the full fruit period can make the trees develop normally, maintain a good tree structure, make the relationship between growth and fruit basically balanced, achieve high yield year after year, and extend the life of the full fruit period as much as possible.
The same old trees can be rejuvenated and maintain a certain yield by updating and pruning. Through the pruning of fruit trees, the crown with good structure, firm skeleton and neat size can be cultivated to meet the requirements of plant spacing.
Reasonable pruning can make the new shoots grow healthily, the vegetative branches and fruiting branches are properly matched, the branches of different types and lengths can maintain a certain proportion, the fruiting branches are distributed reasonably, strong new shoots and enough flower buds are formed year after year, and the yield is high and stable. Reasonable pruning can make fruit trees ventilated and transparent, with good quality, uniform size and bright color.
Fruit tree pruning is an important measure in fruit tree cultivation technology, but only on the basis of comprehensive management of soil, fertilizer and water can it give full play to its role. Moreover, according to the tree species, varieties, environmental conditions and cultivation management level, the plastic pruning technology must be flexibly used to effectively play its role.
Pruning can adjust the balance between various parts and organs of a tree. Because of pruning, under the premise of not reducing root system and absorption, the branches of crown are reduced and photosynthetic efficiency is improved. On the other hand, because of pruning, the leaf area is reduced, the total growth is reduced, and the photosynthetic products and nutrients supplied to the root system are also reduced accordingly, which will inhibit the growth of the root system and then affect the growth of the shoot.
