Pruning rubber trees requires coring, budding and pruning.

1.

When the rubber tree grows to a suitable height, generally 30 ~ 50 cm high, its vertical growth can be changed by coring to promote the germination of lateral buds. The specific operation method is: cut 1/3 or 1/2 from the upper part of the whole main branch to promote the germination of side branches. Generally, 2 ~ 3 lateral buds near the top of branches are easy to germinate, and the tree is cup-shaped or Y-shaped after the lateral branches grow.

Wipe the bud

Hevea brasiliensis has a strong apical advantage, and its lateral buds are difficult to germinate. If you don't pay attention to shaping and pruning, it is easy to grow upright and form an upright plant shape. It should be noted that the buds at the top of the rubber tree can be preserved, as long as the surrounding side branches are cut off.

prune

In winter, the strong trees are pruned again, and the weak trees are lightly pruned. The key point is to prune the upright strong competitive branches from the base. In summer, the principles of re-controlling strong branches, controlling strong branches and keeping weak branches, adjusting and balancing tree potential, re-cutting strong lateral branches, lightly cutting weak branches and keeping more branchlets are adopted to achieve the pruning purpose of highlighting the trunk and promoting the growth of trees.
