The function and purpose of shaping and pruning walnut seedlings

   pruning is an important technical measure in walnut cultivation and management. Shaping is to cultivate a good tree shape with a certain structure in the process of crown formation, which is conducive to growth and fruit. Pruning is to further cultivate and improve the reasonable tree structure and adjust the contradiction between growth and fruit on the basis of plastic surgery. During shaping and pruning, according to the growth characteristics of walnut trees, combined with natural conditions and management techniques, reasonable shaping and pruning can form a good tree structure, make the skeleton firm, and make the tree potential strong and moderate, branches dense and suitable, improve the ventilation and light transmission conditions of the tree body, promote flowering and fruiting, and achieve the goal of early fruit, high yield and prolonging the full fruit life of young trees.

The functions of    shaping and pruning are as follows:

   1. To form a high-yielding tree structure, to build a reasonable tree structure through shaping, and to make all kinds of branches scientific configuration, reasonable structure, plump and compact, and improve the load and fruiting capacity of the tree.

   2. Improving the light transmission condition of the tree can remove the overdense branches, adjust the angle and direction of the branches, make the branches be arranged in a planned and reasonable manner, be clear between the master and the subordinate, ventilated and transparent, which is beneficial to the growth and development of the tree and reduce the damage of diseases and insect pests.

   3. Adjusting growth potential, economic use of nutrients through shaping and pruning can regulate the operation of tree nutrients, achieve economic utilization, make weak trees strong, prosperous trees slow down, old trees rejuvenated, promote flower bud formation and fruit setting, and prolong fruiting years.

   pruning trees, shape with branches; visible immortal, shapeless, balance tree potential, clear master and subordinate; light pruning, combination of light and heavy; measures to local conditions, pay attention to benefits.

In different periods of the development of    fruit trees, there will be a certain standard tree shape due to the development of density, varieties and cultivation techniques. However, in the specific pruning, the tree must be induced to take shape according to the appearance of the tree. The main branches and lateral branches are arranged reasonably to balance the tree potential, so that the growth and fruit are in balance for a long time.
