Shaping and pruning management technology for big cherry trees

Abstract

The invention discloses a shaping and pruning management technology for big cherry trees. The management technology comprises the following steps: dividing a big cherry tree planting region into a plurality of regions; simultaneously planting production main cultural varieties of different varieties of big cherry trees such as early-red precious stone, early-mahapphala, red light, tieton, summit and Brooks in the regions; controlling the content of nutrients and water of soil in the regions, and enabling the nutrients of the same regions to be consistent and the nutrients of the different regions to be different; and randomly carrying out sample investigation on growth lengths of branches of different parts of the big cherry trees in various varieties in the regions in different places atregular times, and drawing a time variable curve chart of the growth lengths of the branches of the various big cherry trees under different nutrition conditions. By the management technology, the optimal time nodes of pruning for the different varieties under different nutrition states can be determined according to growth data of the big cherry trees in different time periods, therefore, errorscaused by the reason that technicians observe growth states of the big cherry trees are avoided, and quantitative data support is provided for pruning of the big cherry trees in the summer.

Description

technical field [0001] The invention relates to the plastic management of large cherry trees, in particular to a management technology for plastic pruning of large cherry trees, and belongs to the technical field of plastic pruning of large cherry trees. Background technique [0002] When planting large cherry trees, summer pruning is an important pruning method. Pruning techniques such as topping, twisting tips, opening angles, pulling branches, and removing back branches are used to control tree potential, adjust tree shape, and promote flowers and fruits. Large cherry trees form a reasonable tree shape, proper tree vigor and maximum fruiting results, thereby increasing production efficiency. The traditional method is to judge whether a large cherry tree needs to be pruned through real-time observation. The best pruning time is often missed due to the growth time difference between varieties, the deviation of judgment standards by different people, and the phenomenon of pr...

The traditional method is to judge whether a large cherry tree needs to be pruned through real-time observation. The best pruning time is often missed due to the growth time difference between varieties, the deviation of judgment standards by different people, and the phenomenon of pruning lag.
