Pruning principle
In order to enter the fruiting stage as soon as possible and bear more fruits, scientific pruning is needed. Pruning usually follows certain pruning principles to ensure the yield of lotus spray. The main principles of general pruning are low trunk, low crown, few big branches, many small branches, moderate control and suitable weight. Generally speaking, it is to shorten the trunk length and reduce the crown height; There are many primary branches on the trunk, and the distribution of secondary branches and tertiary branches is unreasonable, so it is not appropriate to study the spatial structure of each branch. Young trees and poorly growing lotus trees are mainly cut lightly, while healthy trees and old trees should be cut again to adjust their vitality reasonably.
pruning method
the pruning of the lotus tree needs to be carried out according to certain methods, while the general pruning methods of fruit trees are almost the same. Pruning methods mainly include short shearing, sparse shearing, retraction shearing, seedling emergence, ring cutting, branch pulling, branch bending, etc. Thinning and pruning mainly means pruning old branches, diseased branches, weak branches, dense branches, clustered branches and disorderly branches; Telescopic shears are mainly used for pruning old trees; Wiping and releasing buds means wiping off new buds and promoting the growth of branches and leaves in all directions; Ring cutting is to ring cut the lower part of the trunk to achieve the function of catalyzing fruit setting; The main purpose of pulling branches is to adjust the distance between branches and improve the illumination.
young tree pruning
the young tree period is generally from the designated planting period to the fruiting period. Pruning in the young stage of lotus is mainly to form a complete tree. After planting, the trunk of the branches should be reserved according to the growth of the lotus tree. When the lotus tree grows to about 1 meter, the terminal buds should be removed to promote the growth of the secondary trunk, and then gradually form a complete open tree. Before the saplings form to the fruiting stage, we need to prune them properly. At this time, we mainly prune the budding branches and clustered branches and cultivate the fruiting mother branches.
Pruning of fruit trees
Pruning and shaping of fruiting lotus trees are mainly carried out reasonably, so as to enlarge the crown, renew fruiting branches, promote flowering and fruiting, and play a role in increasing production. The fruiting period of the lotus tree is generally pruned three times a year, namely, spring pruning, summer pruning and winter pruning. During this period, pruning mainly involves pruning diseased branches, dead branches, old branches, dense branches, clustered branches, straight branches, drooping branches, cross branches, weak branches, etc. Another point to note is that pruning must be done early in spring, preferably when the branches and leaves sprout; Summer pruning cannot be carried out at flowering stage; Pruning in winter should be carried out as early as possible, which is beneficial to the safety of lotus trees in winter.
In fact, the pruning technology of lotus fog is basically the same as that of common fruit trees, so many methods are universal. But pay attention to the pruning time.
