Dressing and technology of loose forming

Bud peeling treatment, peeling off useless buds to ensure nutrient accumulation; Tillering, that is, pruning twigs or roots on the trunk to avoid nutrient loss; Short-cutting operation refers to cutting off a part of loose branches; Pick the heart and thin the branches, pick the twigs at the top of the tree and cut off the useless branches.

1, bud stripping treatment

Early spring is the germination period of Pinus tabulaeformis, which is the most suitable time to peel the buds of Pinus yunnanensis. Bud peeling refers to peeling off redundant and useless buds on branches to prevent the loss of nutrients. When peeling buds, be careful not to damage healthy and useful buds. The direction of remaining buds does not need to be the same, but it needs to be evenly distributed on each branch.

2. Farming work

When the new buds sprout slowly and grow new branches, it is necessary to cut off the extra branchlets on the trunk or roots. This method is to prevent loose branches from growing too thick and affecting the nutrient absorption of other healthy branches. Be careful not to hurt the bark when operating.

3. Shortcut operation

Short cut is divided into three ways: light short cut, medium short cut and heavy short cut, which means cutting off a part of loose branches. Light and short cutting can promote the growth of middle branches and long branches, and medium and short cutting is beneficial to adjust the tree potential. The choice of specific methods is mainly determined according to the growth state of trees.

Step 4 pick the heart and thin the branches

Picking refers to picking the top shoots in the loose growth period to avoid the branches growing in vain. Thinning refers to cutting off useless branches to enhance the ventilation and transparency of the whole tree, enhance the tree potential and promote the growth of weak branches. In the growing period, spruce pine should be thinned several times, and the cutting mouth should be flush with the raw branches, leaving no dead piles.
