Shooting tips
In order to promote flower bud differentiation and prevent excessive vegetative growth, new shoot tipping methods should be adopted for control. That is, the new shoots that have not stopped growing will be picked up, and the picking position will be generally bounded by a half leaf. After picking the heart, it will stop for 10 to 15 days to send out secondary shoots. When it reaches 15 to 20 centimeters, it will be picked again for the second time. Still half a leaf as the boundary.
Lazhi
After the cherry is harvested, the branches with small angles on the first branch can be drawn so that the angle is 70-80 degrees from the main branch. It can improve the ventilation and light transmission of trees, and at the same time ease the growth potential, which is very beneficial to flower bud differentiation. Pay attention to the mat before the pull to prevent damage mats, so as not to pull the big branch of the skin.
Big branch pruning
Excessive branching and the closure of trees are one of the important causes of the debilitating cherry tree, reduced resistance, and the occurrence of pests and diseases. Moreover, the younger the cherry tree is, the stronger the resistance is, and the pruning of a large branch can improve the overall stress resistance of the cherry. At the same time, through pruning, reduce excessive flower buds and ensure that the next year's fruit is larger.
Removal of large branches should grasp the following aspects:
First, large branch pruning should be carried out from top to bottom. Can not be rushed too much. The large branches removed in summer pruning are about 15% to 20% of the total amount. It is removed year by year according to the condition of the tree. Generally, it is appropriate to complete trimming in 3 to 4 years. . Maintain a relatively dense overall tree shape with a relatively thin main branch above and a lower main branch below.
The second is based on the length of the resulting branch. As a result, the longer the branch, the earlier it needs to be removed, and the more retracting the fruit branches. The tree is compact.
The third is to selectively remove the shoot growth. New shoots with small growth should be removed first.
The fourth is to remove the mastery of time. Removal of large branches can generally be carried out from mid-July to mid-July. In some cases, it can even be carried out during the fruit harvesting period. For instance, the heads of fruits and vegetables may be sawn off under the heads of the fruit after harvesting. Can be. In addition, sawing large branches is generally to avoid the period of heavy rainfall and prevent the flow of glue.
Note that when large branches are removed, it is generally necessary to leave a certain length of branches at the trimming site to promote wound healing and prevent excessive retraction of fruit branches.
