Tea tree canopy culture is an extremely important technical measure in tea planting. It is through pruning to inhibit the tea tree apical dominance, promote axillary bud germination and lateral branch growth, enhance tree vigor, and cultivate high-yielding and high-quality canopy. The canopy culture technology of senescent tea trees is mainly performed with heavy pruning and sassafras.
The heavy pruning of senescent tea trees and taiwan gongs are carried out after the end of spring tea (late May-late July) and cannot be postponed until August.
1. Heavy trimming
The object of heavy pruning is that the half-ageing and premature aging tea trees cut 1/3-1/2 of the height of the original tea tree, and the clippings are smooth, the tea tree should be horizontally shaped, and after the heavy pruning, the fertilizing management must be strengthened to retain the summer shoots. , Autumn tea topping mining, promotion of lignification and branching of new shoots, spring and summer tea should be combined with the growth of the tea tree leaves reasonable.
2. Taiwan
Taiwan's target is an extremely old tea tree. The inside of the tea tree is thick and old, there are many dry branches, and there are many lichens in the lichen. The leaves of the buds are few on the leaves, and the branches are gray-brown. The height of the table is generally 5-10 cm from the ground. Moss tools can be selected from Taiwanese scissors or sharp machete. The cuts require smoothing and sloping to avoid tearing the stumps and trapping rainwater. After Taiwan and Taiwan need other technical measures to match, the effect is significant. Strengthen the management of fertilizers and waters, make sure that it is pruned, keep new shoots, and reasonably pick.
