Double-tape close spacing afforested wood pruning method

A technology of forest tree and plant spacing, applied in the field of pruning and pruning, can solve the problems of affecting the normal growth of photosynthetic reaction trees, poor light transmission conditions, and high pruning strength, so as to facilitate biodiversity and mixed afforestation, expand the canopy gap, and improve the forest environment. Good results

Problems solved by technology

During the growth process of the above-mentioned common 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 number of canopy light receiving area to the land area) decreases rapidly, which seriously affects the photosynthetic reaction and tree growth. normal growth
No pruning or thinning of branches during the period, strong pruning intensity, poor lighting conditions in the forest, and difficulty in afforestation of some tree species in patches

Embodiment 1

[0029] Pruning and pruning of cedar (C. fortunei) trees for double-strip dense afforestation.

[0030] A. Afforestation and planting: afforestation with two dense plants, with a plant spacing of 0.8 meters, a narrow strip spacing of 1.5 meters, and a wide strip spacing of 3.5 meters (see Figure 1). Planted in March, 333 plants per mu.

[0031] B. Pruning: the crown of the tree of shaping is nearly garden columnar (referring to Fig. 3) to form the double strip unit shown in Fig. 2. The length of the wide inner branch is 120-130cm, the diameter of the base is less than 3cm, and the crown gap is 90-110cm; the length of the narrow inner branch is 50-60cm, and the crown gap is 30-50cm. Pruning time: dormant season.

[0032] C. Pruning: No pruning in the young stage, and the branches below 1.5 meters of the trunk are cut off in middle-aged forests.

[0033] D. Thinning: Focus on between plants and within narrow strips. Cut off the weak branches and overlapping dense branches of ...

Embodiment 2

[0037] Sassafras (S.tsumu) was pruned and pruned with double-strip dense afforestation.

[0038] A. Afforestation and planting: afforestation with double dense trees, with a plant spacing of 1.5 meters, a narrow spacing of 2.5 meters, and a wide spacing of 5.5 meters, with 111 plants per mu. Planting time: February.

[0039] B. Pruning: The shaped crown is a double trapezoidal crown (longitudinal section). The length of the wide inner branch is 180-200cm, and the diameter of the base of the side branch is controlled within 4cm, and the excess is sawed off. The canopy gap is 150-190cm; the length of the narrow inner branches is 80-100cm, and the canopy gap is 50-90cm. Pruning time: tree dormancy season.

[0040] C. Pruning: young forests cut off branches with a trunk height of less than 1 meter, and middle-aged forests cut branches with a trunk height of less than 2 meters.

[0041] D. Thinning: focus on the inter-plant (combination between the strips), cut off the delicate...

Abstract

The invention relates to a method for shearing trees, wherein the trees are planted in two bars; the bar distance is 1.5-2 times of tree distance; the unit bar distance is 4-6 times of tree distance; the sick branch and over-density trees are cut off. The invention can improve yield.

Description

technical field [0001] The invention relates to a method for pruning and pruning of timber forests, in particular to a method for afforestation with double dense trees and pruning and pruning to accelerate the growth of trees. 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 seedling pruning method; It ...
