Problems solved by technology

[0006] The technical problem to be solved by the present invention and the technical task proposed are to overcome the problem that the landscape forest seedlings continue to grow and the quality declines due to the deterioration of light conditions after the canopy is closed; propose a kind of pruning technology at an appropriate time, To improve the light environment, increase the light-receiving area of ​​seedlings, and achieve the pruning method of landscape forest seedlings that grow normally, improve quality and yield

Embodiment 1

[0029] Side branch pruning of 1-year-old seedlings of camphora (C.camphora).

[0030] 1. Status of camphor seedlings (see Figure 1): 1-year-old transplanted seedlings with a height of 40-50 cm and a yield of 20,000 seedlings per mu.

[0031] 2. Side branch pruning (see Figure 2): In February of the next spring, prune the side branches of camphor seedlings, and cut off about 1 / 2 of the top of each side tree on average, so that the line between the upper and lower branches is perpendicular to the ground. Leave a space of about 10cm between rows. At the same time, cut off some thin and weak branches; cut off the top tips of some taller seedlings (accounting for about 1 / 3 of the total seedlings).

[0032] 3. Cultivation and management: Same as general landscape forest seedlings.

[0033] The camphor seedlings of the present embodiment, under the same density, after pruning, the height of the seedlings increased by 21% compared with the contrast, the thickness increased by 14%, t...

Embodiment 2

[0035] Side branch pruning of 1-year-old sweetgum (L.formosana) seedlings.

[0036] 1. Seedling status: Drill sowing, 1-year-old seedlings, 50-70cm in height, 25,000 seedlings per mu.

[0037] 2. Side branch pruning: In November of that year, the side branches of the seedlings were trimmed, and 1 / 3 to 2 / 3 of each side branch tip was cut off, so that the pruning surface of the upper and lower side branches was perpendicular to the ground. Keep a gap of 10-15 cm between the rows of seedling crowns. At the same time, cut off some thin and weak branches; cut off the top tips of taller seedlings (accounting for about 1 / 3 of the total seedlings).

[0038] 3. Cultivation and management: Same as general landscape forest seedlings.

[0039] With the liquidambar pruning seedlings of the present embodiment, the yield of standard seedlings per mu is 28% higher than that of the control, the thickness of the seedlings is increased by 16%, and the survival rate of afforestation is increase...

Abstract

A pruning method for the trees in a scenic forest features that the lateral branches of adjacent trees are pruned by 1 / 3-2 / 3 in length for generating a (5-15)-cm gap when the branches and leaves of said adjacent tree are mutually contacted with each other, and the tips of the trees whose height is greater than average height are cut off for balanced growth.

Description

technical field [0001] The invention relates to a tree pruning method, in particular to a pruning method for side branch pruning of landscape forest seedlings to improve yield and quality. Background technique [0002] Pruning is widely used in the production of fruit trees, usually in the planting and juvenile stages, the dry shaping is carried out, and the plants are pruned into a certain shape. Such as the natural happy shape of a peach tree, the evacuated layered shape of a pear tree, etc. [0003] The pruning of Kudingcha usually follows the method of tea leaves. When the trunk reaches a certain height after planting, the pruning height for the first time is about 20cm-30cm. Breed annually thereafter for pruning. As an adult high-yield tea garden, the pruning and picking surfaces are basically on the same level, and the sun-receiving area coefficient of the canopy is about 1, that is, the picking surface is roughly equal to the area occupied by...
