Embodiment

[0037]1. Yuwang forest area covers an area of ​​62 hectares, with an altitude of 50-210m. There are pure masson pine forests planted in the 1950s. After 1990, due to the harm of pine wood nematode, a large number of masson pine trees withered and died. The shrub layer with higher density is mainly the shrub layer dominated by many positive shrubs and Schima superba. The potential vegetation type of the site is the Schima superba-Castania chinensis group. According to the measurement of the soil in 1990, the soil organic matter is 3.17%, the total nitrogen is 0.079%, and the total phosphorus is 0.0192%. Compared with the typical evergreen broad-leaved forest (organic matter 5.3%, total nitrogen 0.5%), it is obviously lower; Above this woodland is divided into 2 blocks, one is the technical operation of the present invention, and the other is the conventional forestry cultivation operation. The test area is 15 hectares and 0.67 hectares.

Abstract

The invention discloses an early-wood-promoting cultivation method for a schima superba forest. The method comprises the steps: carrying out young-stand tending: carrying out tending transformation management on young stands; carrying out forest-stand colonization stage management: after tending transformation, carrying out released thinning on fully-stocked forest stands once, cutting shrub and herbaceous plants, and carrying out vine-removing tending management; carrying out target wood cultivation: selecting and cultivating target woods; and finally, carrying out forest-stand early-wood growth stage management, including: selecting or rejecting the target woods again, carrying out density regulation and control, carrying out forest land management, carrying out soil management and carrying out renewing management. The method has the technical advantages that forest trees of the schima superba forest are healthy in growth and vigorous in growth vigor; and compared with the conventional / traditional forest industry operation methods, the average diameter at breast height of the forest trees, the stocking volume of forest stands and the number of advantageous target wood individuals can be improved, offspring renewing seedlings and young trees are abundant, the quality of forming of early wood of schima superba is effectively improved, the benefit is remarkable, so that the method can be popularized to production. Simultaneously, the method can also be applied to the early-wood-promoting cultivation of other timber trees.

Description

technical field [0001] The invention relates to a method for cultivating woody plants, in particular to a method for promoting the cultivation of early wood of Schima superba. Background technique [0002] Schima superba Gardn.et Champ is a large evergreen tree of the genus Schima superba Gardn.et Champ in the family Theaceae, up to 28m in height, 78cm in diameter at breast height, with dark brown bark and massive longitudinal cracks; dark gray twigs with obvious lenticels; tall and straight tree shape , the trunk is straight; the leaves are leathery and fire-resistant; the flowers bloom in April-May, and the flowers are white, and the fruit matures in September-October of the following year, and the capsule is nearly spherical; the seeds are kidney-shaped, with wings on the edge, and the natural seeding ability is strong; the wood is tough , dense, not easy to crack and deform after drying, corrosion-resistant, smooth cut surface. It is distributed in all provinces and cit...
