The pruning of tree heads can reduce tree height and improve lighting at the lower part. This is a theoretical understanding, but in some operations, some orchard tree heights have been lowered, but the light has not improved but it has become worse. The negative growth of the tree, always maintain a certain tree height, but this height is not unlimited, 'more than the root growth force is not dead dead old', so the need for timely trimming. For some tall trees, due to the convenience of planting management or the renovation of closed parks, pruning often requires falling. If closed vegetation is caused by pruning, most of them are caused by unreasonable pruning of individual plants and improper plastic arranging. For the treatment of such single plants, pruning should first open glazing, side light, and more The method of sparse branch adjustment, 'cut 1 cut 2 not cut 3'. However, for those branches that are spawned, the base branches are too low, and the cut 2 can't solve the problem at all. You can consider cutting 3, and the specific cutting is not the number of deaths. It can be flexibly used according to the different conditions of the tree. Cutting branches to open the space is conducive to light, conducive to orchard operations, the most important is to solve the tree's airways, improve the photosynthetic performance. To deal with the big branch problem, do not rush to drop your head in the past, and you need to stay a tree head to help ease the situation. You can eliminate excessive branches in the upper part of the tree to ease the situation, and wait for the upper branch to deal with almost the upper forces to ease the weakening and then consider the falling head, so as to avoid too urgent and anti-Wang umbrella phenomenon, 'the garden did not see the light canopy shelter The sun hasn't seen fruit and fruit above the crown.' Once the umbrella lighting will be more deteriorated, it also brings two troubles to the pruning without cutting the shade to cut the missing branches. The correct fall should be based on the growth status of the tree, prioritize and carry out the planned and step-by-step process. After the tree head is weak, it is generally required to stay with the branches, or choose a new one to be cultivated again to let the tree stand In the cycle of falling heads, cultivating and falling heads, the crown volume will remain large and small. The method is not a dead end, such as due to personal needs to reduce the main branch of a one-time heavy drop of the head, then you predict the pruning response, take appropriate measures to eliminate or reduce the negative impact of falling head. To achieve the purpose of personal pruning.
