Embodiment

[0054] 1 Retrofit site selection:

[0055] Mainly select the middle and lower parts of low mountains and hills, the forest land with good soil fertility, and the original vegetation before the invasion is broad-leaved forest as the reconstruction site.

[0056] 2 Moso bamboo forest clearing:

[0057] 2.1 Old bamboo cleaning:

[0058] At the end of summer and early autumn, the "plum blossom knife" technique was used to cut down the invasive moso bamboo at a distance of 5cm from the surface, and all the felled moso bamboo and branches were removed outside the forest; Rotten trees, dying trees and shrubs shall be cut down together; vigorous tall trees and understory shade-tolerant tree species shall be retained.

[0059] 2.2 Hsinchu Clearance:

[0060] In the season of bamboo shoots in late spring and early summer, new bamboos were cut down for three consecutive years, weakening the growth potential of new bamboos year by year.

[0061] 3 tree species to choose from:

[0062...

Abstract

The invention discloses a method for transforming a broad-leaved forest against invasion of phyllostachys pubescens. The method is characterized by comprising the following steps of (1), clearing or cleaning of phyllostachys pubescens, wherein aged phyllostachys pubescens is cleaned, and new phyllostachys pubescens is cleared off; 2, selection of tree species, wherein after the transformation in the first step, the tree species for resisting to phyllostachys pubescens are planted, and the native tree species are adopted; 3, mode configuration, wherein conservation of original tree species, artificial replanting and regeneration under the forest are included; 4, final-period management. The method can effectively solve the problems that the area of the broad-leaved forest area is decreasedbecause of invasion of phyllostachys pubescens, the diversity of the tree species is reduced, natural regeneration capacity is poor, and forest land nutrients are poor. In the method, through clearingof phyllostachys pubescens, selection of the tree species and mode configuration, the invasion of phyllostachys pubescens can be effectively reduced, the biological diversity of plants is restored, and the biological diversity of underground part soil is also restored.

Description

technical field [0001] The invention belongs to the technical field of forestry protection, and in particular relates to a method for transforming a broad-leaved forest aiming at invasive moso bamboo. Background technique [0002] After nearly 20 years of implementation of the public welfare forest protection project, most of the secondary broad-leaved forests in southern my country have suffered from the invasion of moso bamboo forests, resulting in the shrinkage of the broad-leaved forest area, the reduction of tree species diversity, poor natural regeneration ability, and the lack of nutrients in the forest land. The quality and function of secondary forests are significantly reduced. [0003] Moso bamboo is useful in many industries and has high economic benefits. The underground whip root system of Moso bamboo is well developed and has strong penetrating power, and then continues to spread to the surrounding broad-leaved forests and replace the original broad-leaved fore...
