Pruning technology of walnut tree

The golden age of walnut tree pruning is when the frost falls to early winter, when pruning has the least bleeding and the least nutrient consumption. 1. Keep your head down. After thousands of years, after picking walnuts, the first task is to turn around in time. 2. Short scissors. Walnut has weak sprouting and branching ability, sparse crown branches and many invalid spaces. Proper cutting can enlarge the crown, promote branching, enrich the inner branches and increase the fruiting parts. 3. Shrinkage and shearing. There are many drooping branches under the back of walnut trees, which affect the growth of main branches and lateral branches, and should be retracted in time to control them. 4. thinning. Walnut trees have fewer branches. Generally speaking, we should leave as many as possible. For some branches that are too dense, if they cannot be cultivated into backbone branches and fruiting branches, they should be thinned in time. 5. Choose your heart. For the long branches in the crown, the upright flourishing branches and the vain long branches, when there is room for cultivating branches, we should pick the heart in time. 6. Sparse male inflorescence. In this way, it is difficult for weak branches to form female flower buds, but a large number of male flower buds are formed, which consumes nutrients and water in the tree, thus affecting the fruit setting rate of female flowers. Therefore, removing most male flower buds can save nutrients and water and improve walnut yield.
