Embodiment 1

[0037] Embodiment 1: Cultivate poplar plywood surface veneer. It is required that the diameter of the tree stem should be more than 300mm, and the length should be more than 2.6m. It should be straight, round, small in taper (convenient for rotary cutting and centering), no dead joints, and consistent in color. Adopt the method of the present invention and can select the target tree that meets the requirements in forest land and carry out shaping, trunk height is controlled at 2.6m (1 section), or 5.5m (2 sections), 8m (3 sections), 11m (4 sections), suitable for Plywood lumber length requirements. The canopy is controlled into compact oblate, umbrella, and mushroom shapes through arrangement.

Embodiment 2

[0038] Example 2: Camphor tree is one of the main timber species in Hunan. The side branches of the camphor tree are very developed, the crown is large, the main pole is not high, and the proportion of the main pole of the tree is small. Under the natural growth state, the output of the main pole material per mu of the camphor forest is only 2 to 3 cubic meters. By adopting the technology of the invention, the output of main rods can be greatly improved through directional cultivation.

[0039] According to the cultivation objectives and site conditions, the height of the main pole of the camphor tree is controlled at 6-8m; the crown is shaped, the elongated branches are cut off, the side branches are shortened, and the thin side branches are increased to cultivate a compact, plump, oblate spherical, umbrella-shaped or mushroom-shaped crown. Thereby reducing the proportion of side branches, increasing the main trunk, cultivating straight, round, small taper, no dead joints, h...

Abstract

The invention belongs to the technical field of forest cultivation, in particular to an artificial efficient directional cultivation method for a high-quality large-diameter commercial forest. The method is characterized by comprising the follows: shaping trees at a fixed period, controlling water sprouts, trimming cellae withered branches, promoting new branches, increasing photosynthetic area, namely leaf area and promoting tree growth. The method specifically comprises the technical means of top removing, branch cutting, branch shaping and trimming, sprouting, crown finishing, flower and fruit thinning and the like. The method solves the problems of more small-diameter wood, less big-diameter wood, more low-quality wood, less high-quality wood, more ordinary wood, less precious wood, less special wood, less directional wood and bent, eccentric, tapered and decayed main stems in the wood cultivation process.

Description

technical field [0001] The invention belongs to the technical field of forest cultivation, and in particular relates to a method for artificially high-efficiency directional cultivation of high-quality large-diameter timber forests. Background technique [0002] The amount and quality of a country's timber storage are important indicators to measure its wealth and forestry level. In recent years, my country is implementing a timber strategic reserve plan, and it is of great significance to promote and apply advanced science and technology. [0003] Wood is divided into two categories: coniferous wood and broad-leaved wood. Most of the precious materials come from broad-leaved wood. Timber mainly refers to the trunk part of the tree, and the growth of the trunk includes tall growth and diameter (coarse) growth. Therefore, the length, thickness, shape, proportion of the trunk of the tree, and the speed of growth are closely related to the cultivation level and cultivation te...
