Published: 2024-11-21 Author: mysheen
Last Updated: 2024/11/21, The main results are as follows: 1. According to the characteristics of varieties, different varieties, different growth and fruiting habits, different pruning responses, different pruning technical measures. 2. According to the age of the tree, the growth of the fruit tree is different, and the growth is also different according to the site and management conditions.

   1. Pruning different varieties according to variety characteristics, different growth and fruiting habits, different pruning responses, different pruning technical measures.

   2. According to the age of the tree, the growth of the fruit tree is different, and the growth is different according to the site and management conditions. The younger the tree is, the stronger the growth is, the lighter the pruning should be; the older the tree is, the weaker it is, and the pruning should be heavier.

   3. Pruning the same variety according to different pruning responses due to different branch types, growing positions, straight branches, growth forces and the degree of short pruning, the responses after pruning are different, and corresponding pruning measures must be taken according to their reaction rules.

   4. Pruning according to site conditions and management levels has great differences in the growth and development of branches and buds under different site conditions, environmental conditions and management levels, so corresponding pruning measures should be taken according to their specific conditions.

The trend of    shaping and pruning

With the development of    production and science and technology, the shaping and pruning period and pruning technology of walnut have also changed.

   1. The changes of planting density and tree shape are mainly shown in the development from Arbor sparse planting to dwarfing and dense planting, tree shape from large crown to small crown, from multi-level and multi-level tree structure to less-order and less-level tree structure. Walnut tree crown sparse layer shape and spindle shape gradually replaced the previous evacuation stratification.

   2. The change of pruning technology has developed from tedious pruning in the past to simplified pruning, from heavy shearing to light shearing, from single scissors to the comprehensive application of knife, shearing, sawing, chemical control and manual twisting, picking, engraving, peeling and taking.

   3. The change of pruning period has developed from paying attention to winter pruning and neglecting summer pruning to winter, spring, summer and autumn pruning, and paying attention to the comprehensive application of pruning techniques.
