The pruning of walnut trees in autumn and winter is an important technical measure in early walnut cultivation. While conducting soil and fertilizer water management and pest control, the proper pruning of walnut trees will help achieve the purpose of high quality, high yield and stable production of walnut trees. Pruning time Insect net greenhouse also known as plant and vegetables greenhouse net. Used for prevent the insect fly into the greenhouse during the plant growing, and cover the plants. Key off the approaches that the pests (adult insect) breeding. Effective control of the spread of all kinds of harmful pests spread, such as Cabbage caterpillar, diamondback moth, aphids, flea beetles, Sweet agnates, American leaf miner, literal etc and prevent the harmful of virus spread. Significantly reduced the use of chemical pesticides, so that the planting vegetables good-quality and health.

The pruning period is most suitable from late autumn to early winter, that is, after October, the leaves begin to yellow before they have fallen. Since the leaves do not fall, the dense branches and the light-blocking branches can be easily distinguished and removed, so as to facilitate ventilation and light transmission, and there is no injuring phenomenon at this time.
Pruning method
Sapling pruning walnut tree sapling nutrition, rapid growth of shoots, tree crowns expanded year by year, pruning at this time should pay attention to cultivating the trunk, leaving the main branch, retaining auxiliary branches, timely sparsely cut densely squeezed branches, leggy branches, thin branches , leave more branches in the crown. Stand upright and long branches, lay flat and put slowly, so as to ease the growth of branches and promote the formation of the resulting branches. In addition, use a short cut and slow release method to increase the amount of branches.
The results tree pruning sparse dense branches: early solid walnut branches, easy to cause more litchi in the crown, the density is too large, is not conducive to air and light. In this regard, in accordance with the principle of weakening and keeping strong, excessive dense branches should be removed in time. The specific method is to cut off the base of the branches and must not be left behind in order to facilitate wound healing.
Treatment of back branches and branches under the back of the main branches and more back to the main branch of the spring, early spring germination, strong growth, strong competitiveness, easy to weaken the original branches, and the formation of "inverted pull" phenomenon, and even cause the original branches withered. The method of treatment is to cut off after germination or at the initial stage of shoot elongation. If the original main branch becomes weak or the branching angle is too small, the lower branch or oblique upper branch may be used instead of the original branch head, and the original branch head may be cut off or cultivated into a result branch. If the lower branch has a moderate growth and mixed shoots have formed, the result can be retained. If the back branches grow robustly, they can be retracted at the appropriate branches and cultivated into small fruiting branches.
