Cedar trunk should be righted when bent
Cedar adopts the shaping method of low branched central leadership stem. For the seedlings with bent and weak head, the young shoots should be bound with thin bamboo rods to make the trunk straight. At the same time, the growth advantage of the top should be used to promote them to grow higher. Bind once a year. If competitive branches are found on the trunk of cedar, choose one as the central leader, and the other will be shortened and retracted, and the shortened branch will be removed the next year p>
Selection and retention of large lateral branches of cedar
Because the lateral branches of cedar are in irregular rotation, with a large number and too small spacing, and the tree crown is lush and closed, resulting in uneven nutrient distribution, and the growth of each lateral branch is often very uneven. Therefore, when pruning, it is required to arrange each lateral branch in layers on the trunk. About 4-6 lateral branches should be reserved in each layer, and the distance between layers is about 30-50 cm. Pay attention to protecting the new shoots, and remove the dense branches, weak branches and disease and insect branches at the same time. For the thicker branches that are not used as lateral branches, they should be cut short and raised for a period of time before treatment p>
Cedar trees need to be balanced
In order to form a beautiful cedar crown, the length of the lower side branches is required to be shortened upward in turn. In addition, the growth of the side branches on the same layer needs to be relatively balanced. Therefore, when shaping and pruning, we should pay attention to the relative balance of the growth of each lateral branch. The branches with strong growth can be properly retracted and cut, and the weak growth parallel branches or drooping branches can be selected to replace them, so as to balance the tree potential p>
Adjust the cedar tree of "strong at the bottom and weak at the top"
Retract and trim the strong branches, overlapping branches and parallel branches at the lower part, and spray an appropriate amount of growth hormone on the upper plant to promote the growth of branches p>
Pruning of cedars
For skew trees, the method of leading branches to fill the empty space can be adopted, and the larger branches nearby can be pulled over with rope or iron wire to fill the empty space; Or adopt the grafting method to graft robust and plump buds on plants with large gaps and no branches by abdominal grafting, so as to promote the germination of new branches< span>
