Problems solved by technology

During the growth process of the above-mentioned commonly used afforestation trees, especially after the canopy is closed, the light transmission conditions in the forest are getting worse day by day, and the canopy lighting coefficient (the canopy lighting coefficient refers to the ratio of the canopy light receiving area to the land area) decreases rapidly, which seriously affects photosynthetic reactions and normal growth of trees

Embodiment 1

[0030] Carry out six-strain cluster afforestation and pruning and pruning of Cedar (C. fortunei):

[0031] 1. Afforestation and planting: six-strain group afforestation, the seedlings are distributed in groups on the forest land, 6 plants in groups: 1 plant in the middle, 5 plants around. The distance between plants is 0.9 meters, and the distance between groups is 3.5 meters. There are 54 groups per mu, and 324 plants are planted (see Figure 1).

[0032] 2. Pruning: the juvenile stage is pruned into a cylindrical crown, and the middle-aged forest is pruned into a pagoda-shaped crown with a pentagonal bottom (see Figure 2). The length of side branches between groups is 120cm, and the length of inner branches of groups is 60cm. The maximum diameter of the side branch base is 2.5cm, and the crown gap is 65cm (see Figure 3).

[0033] 3. Pruning: No pruning in the early stage of juvenile, and branches below 1 meter in trunk height are cut off in the later stage of juvenile. Af...

Embodiment 2

[0037] Carry out six-strain cluster afforestation and pruning of Kudingcha (I. latifolia):

[0038] 1. Afforestation and planting: six-strain group afforestation, the seedlings are distributed in groups on the forest land, 6 plants in groups: 1 plant in the middle, 5 plants around. The distance between plants is 1 meter, and the distance between groups is 4 meters. There are 42 groups per mu, and 252 plants are planted.

[0039] 2. Pruning: with embodiment one.

[0040] 3. Pruning: No pruning in the young period, and the middle-aged forests cut off the branches with a trunk height below 1 meter.

[0041] 4. Thinning: with embodiment one.

[0042] 5. Cultivation and management: same as general ecological forest.

[0043] In the present embodiment, the 8-year-old Kudingcha ecological public welfare forest height growth ratio increased by 32%, and the fresh (tea) leaf yield increased by 62% compared with the contrast.

[0044] Notes:

Abstract

A pruning method for the trees in the 6 trees grouped forest features that the crown of each young tree in a group is pruned to become cylindrical shape and the crown of each group of 5 trees in middle age phase is pruned to become a tower shape with a pentagonal bottom while the branches in the group are pruned.

Description

technical field [0001] The invention relates to a method for pruning and pruning of timber forests and ecological forests, in particular to a method for pruning and pruning trees of six-strain group afforestation to increase growth. Background technique [0002] Pruning is widely used in fruit tree production, usually in the planting and juvenile stages, the stems are fixed 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. At the same time, diseased and insect branches, leggy branches, etc. need to be cut off. The central link is to make the canopy receive sufficient light, the fruit grows robustly, and achieves the purpose of high yield. The area coefficient of the canopy of fruit trees is generally greater than 2. [0003] Application number is 03116395.5 (publication number is CN1535565A) the invention patent application discloses a kind of Kuding tea...
