Embodiment 1

[0038] Afforestation and pruning of P. kaempferi timber forest with double-strain canopy.

[0039] 1. Afforestation and planting: double-plant canopy planting method, 2 plants per canopy, the distance between the canopies is 2.33 meters, and the distance between the plants in the canopy is 0.8 meters; 123 canopies and 246 plants per mu; planted in March. (See Figure 1)

[0040] 2. Pruning: For 2-5 year old forests, the crown of the tree is trimmed into a conical shape, and the gap between the crowns is reserved. For 6-10-year-old forests to the middle age, stop pruning the side branches between the plants in the canopy, and comprehensively prune the side branches between the canopies, and at the same time control the strong branches. The two trees in Pengzhong are combined into one to form a unified tree crown, which is in the shape of a cuboid crown. The length of the side branches is 70cm, and the gap between the canopies is 40cm. (See Figure 2, 3)

[0041]3. Pruning: 2 ...

Embodiment 2

[0045] Afforestation and pruning of Kudingcha (I. latifolia) ecological forest with double-strain canopy.

[0046] 1. Afforestation and planting: Double plant canopy planting method, 2 plants per canopy, the distance between the canopy is 2.67 meters, and the distance between the plants in the canopy is 1 meter. Each 94 canopy, 188 plants. Planting time is February.

[0047] 2. pruning: pruning method is the same as embodiment one. The canopy gap between the tents is 50cm, and the length of side branches is 60cm.

[0048] 3. Pruning: with embodiment one.

[0049] 4. Cultivation and management: the same as ordinary ecological public welfare forests.

[0050] When the present embodiment Kudingcha ecological public welfare forest is 5-8 years old, the annual output of fresh (tea) leaves is 135% more than that of the contrast, and the high growth ratio is 21% higher than that of the contrast.

Abstract

A pruning method for the trees in a two trees grouped forest features that the crown of each young tree group is pruned to become conic shape in its early phase and then pruned to become cylindrical shape in its later phase or in its middle age phase while its branches are slightly pruned for improving its optical energy utilization rate.

Description

technical field [0001] The invention relates to a method for pruning and pruning of woody plants, in particular to a method for pruning and pruning and promoting the growth of timber forests and ecological forests afforested with double-plant canopy. Background technique [0002] Pruning and pruning (pruning said in the present invention refers to cutting off a part of side branches; pruning is to remove whole side branches from the base, including thinning branches) is a common measure for obtaining a good tree crown, and is generally used In the production of fruit trees, usually during the planting and juvenile stages, fixed-dry shaping is performed, 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, t...
