The pruning method of rubber tree

Rubber trees, also known as rubber trees, Brazilian rubber, etc., are large trees of the genus Ficus of Moraceae, native to Brazil, and are now widely cultivated in tropical Asia. They are of high ornamental value and are very suitable for indoor beautification. Small and medium-sized plants are often used to beautify the living room and study. Medium and large plants are suitable for layout on both sides of the foyer of large buildings and in the center of the lobby. Let's take a look at the pruning methods of rubber trees.

The pruning season of rubber trees

The pruning of rubber trees should pay attention to "winter pruning, summer control side". That is, heavy pruning of strong trees and light pruning of weak trees in winter, with emphasis on pruning upright and strong competitive branches from the base. In summer, the pruning of rubber trees should be carried out to re-control the strong branches, control the strong and retain the weak, adjust the balance of the tree situation, and master the principles of strong side strike, heavy pruning of strong branches, light pruning of weak branches and more twigs, so as to achieve the pruning purpose of highlighting the trunk and promoting the growth of trees.

The pruning height of rubber trees

The trimming cut of the rubber tree should be smooth and strictly prevent the wall from cracking. The suitable height of stubble is 1 cm to 2 cm. Too high and too low will affect wound healing and tree growth. The suitable pruning season for rubber trees is early spring or late autumn and winter. It is suitable for early spring before the sap flows. If the tree is pruned when it sprouts, the water transpiration is fast, the water is lost, and a lot of nutrients are consumed, which is not conducive to the growth of the tree. If the rubber tree is pruned in summer, be careful not to prune on cloudy and rainy days, so as not to soak the wound and become infected with diseases.

Pruning techniques of rubber trees

In the shaping and pruning of rubber trees, it is sometimes necessary to highlight the trunk or the growth of the main branches, remove the dense branches or affect the shaping of the branches, commonly used to highlight the trunk, the main branch shaping and pruning methods are wiping buds and thinning branches. To erase the budding buds, to achieve the purpose of inhibiting the growth of lateral branches, the principle is to eliminate the growth of lateral branches in the budding state, so that nutrients are concentrated to supply the growth of main branches. That is, the branches are cut off from the base of the branches with shears, which are often used to remove overdense branches, and thinning is a remedial measure for wiping buds, that is, because the buds are not wiped in time, lateral branches have been formed, and some redundant lateral branches are removed in order to strengthen the growth or modeling of the trunk.

Pruning and maintenance of rubber trees

In order to prevent the loss of too much milk from the cutting mouth and affect the survival of rubber trees after pruning, the wound should be smeared with plant ash in time. The treated cuttings are cut in the bed with river sand or vermiculite as the matrix, keep the bed with high humidity after cutting, and often sprinkle water to the ground (but not stagnant water) to improve the air humidity. Under the condition of 18-25 ℃ and semi-overcast, it can take root after about 2-3 weeks.
