The procedure of shaping and pruning of Garden trees

The procedure of shaping and pruning of Garden trees

(1) observe the whole tree shape before climbing the tree. Try to keep the tree shape unchanged during pruning.

(2) remove withered branches, disease and insect branches, etc.

(3) when the hairy branches on the big branches and middle branches are removed, the distance between each two hairy branches should not be lower than that of lm.

(4) pruning in the order of first up then down, first big then small, first inside then outside: ① selects a branch with better growth and correct direction as the main tree head to retain, and the weight of the surrounding branches can not be higher than that of the main tree head. ② removes cross branches, parallel branches, overlapping branches, over-dense branches and redundant large branches in the order from top to bottom. Try to do as much as possible: "a. Go and stay, b. Go old and stay new, c. Go down and stay" principle. The removal of branch weight can not affect the overall tree shape, can not be in space, if the residual branches affecting the tree shape can be retained, wait until the growth of new branches next year, and then choose to remove the residual branches.

(5) remove the small branches on the reserved branches: ① remove the medial branches and retain the lateral branches; remove the inward growing branches and retain the outward growing branches. ② removed the superior dorsal branches, while the inferior dorsal branches (upward and downward growing branchlets) retained parallel branches as far as possible. ③ removed cross branches, overlapping branches and parallel branches. When ④ removes the coarse branch and retains the twig, it should be intercepted beyond the original part, and when removing the twig and retaining the coarse branch, it should be intercepted close to the raw part. The upper and lower branches of ⑤ should be divided into layers through light and air, and the amount of pruning can reach 1 × 3 to 3 × 5. It is appropriate to retain the branchlets and get sufficient nutrients. ⑥ prunes the big branches from top to bottom on the basis of the shortest branches, and the overlong branches should be retracted so that the whole tree remains round and looks like an umbrella from a distance. When ⑦ is trimmed into clumps, the whole clump of trees can be pruned as a big tree, and the containing branches can be removed as far as possible to keep the whole clump of trees round in appearance.

In a nutshell, it is "one knowledge, two look, three cuts, four take, five protection". It is known that pruning personnel must know the quality requirements and operating specifications of pruning. Second, for each tree, you can see what to cut first and what to cut later, so that you have a good idea. Three shears, trim according to operating specifications and quality requirements. Take four, take away the pruned branches in time. Fifth, protection, protective measures. For example, when pruning a large tree with a diameter above 3cm, the cut must be cut flat, and the cut must be smeared with preservative (plant wound healing paste).

Finally, the tree is checked after the pruning is completed, and the inappropriate places are modified again.
