Pruning is to continue to cultivate and maintain the structure of high-yield trees and adjust the balance between growth and fruit on the basis of plastic surgery, so as to maintain high quality and high yield of pear trees every year.
Although the concepts of shaping and pruning are different, they are interdependent and inseparable. Both of them have the same purpose, both for the high quality, high yield, high yield, stable yield, long life and good economic benefits of pear trees.
Pruning pear trees is a technical measure to transfer according to the biological characteristics of different systems and varieties, environmental conditions, comprehensive management of fertilizer and water, and comprehensive prevention and control of pests and diseases. Therefore, plastic pruning must be combined with comprehensive management of soil, fertilizer and water and comprehensive prevention and control of pests and diseases in order to give full play to its yield-increasing effect.
Plastic pruning is an indispensable technical measure in pear cultivation and management, and it is irreplaceable by other technical measures, but it is by no means omnipotent or unique. It must be treated correctly and used carefully. If the role of pruning is emphasized unilaterally and other technical measures are ignored, or pruning is opposed to other technical measures; Too much emphasis on tree shape, pruning for pruning; Or do not pay attention to pruning, can not give full play to the role of plastic pruning, to achieve early fruit, high quality, high yield and high efficiency, but will lead to late fruit bearing of young trees, low yield of big trees, poor quality and short economic life.
