Embodiment 1

[0029] After 4 years of afforestation, when the height of the plant reaches 6m and the diameter of some side branches at the base reaches more than 2cm, you can use a sharp saw to trim the lower branches of 1 / 4 of the crown length with a sharp saw, and use a high branch saw to do it again after 3 years. Pruning, after pruning, use oil-based paint to smear and protect the saw edge, and apply it to completely cover the opening.

Embodiment 2

[0031] After 5 years of afforestation, when the plant height reaches 7m and the diameter of some side branches at the base reaches more than 2cm, you can use a sharp saw to trim the lower branches of 3 / 8 of the crown length with a sharp saw, and use a high branch saw to do it again after 4 years. Pruning, after pruning, use water-based paint to smear and protect the saw edge, and smear it until it completely covers the opening.

Embodiment 3

[0033] After 4 years of afforestation, when the height of the plant reaches 6m and the diameter of some side branches at the base reaches more than 2cm, you can use a sharp saw to trim the lower branches of 1 / 2 of the crown length with a sharp saw, and use a high branch saw to do it again after 4 years. Pruning, after pruning, use filling spray paint to smear and protect the saw mouth, and apply it to completely cover the mouth.

Abstract

The invention provides a castanopsis hystrix afforestation pruning method, and belongs to the technical field of garden management. The castanopsis hystrix afforestation pruning method comprises the steps that after afforestation is conducted for 4-5 years, pruning is conducted when the plant height of castanopsis hystrix reaches 6-7 m, the pruning amplitude is 1 / 4-1 / 2 of the crown length, and after pruning, a cut is smeared with a protective agent. According to the method, based on the research on adult single-plant wood knot scar distribution, the formation of wood knot scars is reduced through a pruning mode in the early growth stage, so that the wood income is improved; investigation on tree growth and scar healing conditions after pruning shows that reasonable pruning and protection measures are crucial to reduction of scar formation and improvement of the roundness of a trunk.

Description

technical field [0001] The invention belongs to the technical field of garden management, and in particular relates to a red cone afforestation and pruning method. Background technique [0002] Castanopsis hystrix is ​​an evergreen tree of the Fagaceae family, and is an important native and precious tree species in South China, with important economic and ecological value. At present, the market demand for high-quality large-diameter non-knotted timber is increasing year by year. Red cone wood has high density, high hardness and fast growth rate, which is suitable for cultivating high-quality non-joint timber. After scientific and refined management, red cone can be used to fill precious hardwoods in the future. market demand. However, its natural pruning ability is poor, and the branches at the base are relatively sturdy. After the branches die, they continue to adhere to the trunk. The wood at the base forms a large number of knots, which significantly affects the quality...
