When walnut tree pruning was
In September, walnuts in the suburbs of Beijing have been gradually harvested. It is also the period of walnut tree pruning. During the fruiting period of the walnut trees, the crown gradually opened due to the gradual growth of centrifugal growth and increased fruit load. If the timely trimming is not performed, the ability to expand the canopy weakens as the result of the increase, and then the extension of the canopy, the drooping branches, The thin and weak branches increased, the resulting parts moved outwards, and the canopy was poorly ventilated, causing some branches to become weak and dry. Trim to pay attention to three points: First, the pruning of the backbone branches: In order to control the height of the result tree, we can use the top trigeminal branch to gradually drop the head and replace the tree head with the top branch, so that the height of the tree is controlled at about 6 meters. As a result, the main branches at all levels of the tree continue to extend and the canopy is also expanding. To this end, we must pay attention to cultivating a solid and gradually extending skeleton, timely control of the back branches, and retraction of the branches to replace the original to maintain the growth of the branches. If the extension of the branches is prolonged, the branches can be taken on oblique branches to rejuvenate the branches. Second, the pruning of the branches: the dense branches, cross branches, overlapping branches on the periphery of the crown should be given timely sparse or retraction. For some weak branches that have insufficient light and consume more than they have accumulated, they should be removed in time, so as to meet the requirements of peripheral branch evacuation and internal emptying. Third, fruit branch group pruning: For the results of the walnut tree, there must be a plan to select, cultivate the results of Zhizu. The method is as follows: The auxiliary supporting branches can be transformed into large-sized or medium-sized branches according to the size of the occupied space and the distance from the peripheral branches. The use of strong development branches, against the growth of the main branch, the central branch of the lateral branch or outside, can go strong and stay weak, go straight to stay flat, the development of the remaining branches will be gradually transformed into medium or small branches. To control leggy branches, they must be controlled and used for the internal branch's leggy branches, where appropriate, and without affecting the ventilation and light transmission. It is usually put in the first year of the year, and is retracted at the weaker branches in the second year and cultivated into a small result branch. Keep a distance of 60-100 cm between each group for ventilation. For aging branches, it should be retracted and rejuvenated in time. JIANGMEN EASY TECHNOLOGY CO.,LTD , https://www.easylife-tech.com
