2. Bud fixing: When pruning, pay attention to highlight the trunk and main branches, loosen the branches that are too dense, and do a good job of germination. Break the budding bud to inhibit the growth of lateral branches. The main principle is to eliminate the eruption of lateral branches, which are the concentrated supply of nutrients for the growth of main branches.
3. Re-cutting: Re-cutting refers to cutting off the upright and strong branches from the base. Generally, heavy pruning is carried out in winter, and branches are pruned greatly, following the principle of starting from strong lateral branches, heavy pruning of strong branches and light pruning of weak branches, so as to accelerate the growth of plants. When pruning rubber trees, attention should be paid to the smooth incision, and the stubble height should be early 1-2 cm, neither too high nor too low.
4. Treatment after pruning: After pruning, the rubber tree needs wound treatment. Generally, a lot of juice will flow out at the incision. In order to avoid excessive juice loss, leading to infection. Generally, just put some plant ash on the wound.
