Embodiment 1

[0018] A method for promoting the regeneration of Nannan natural forests, comprising the following steps:

[0019] (1) Selective thinning: During November to December, thinning was carried out on the natural forest stands of Phoebe macula with excessive density, so as to improve the light conditions under the forest and eliminate the limitation of the growth of Phoebe mamba seedlings due to insufficient light under the forest. When thinning, cut down the old, sick, and residual individuals of non-Phoebe species, so that the arbor space of the stand is evenly distributed 90-110m 2 The canopy density of the forest canopy is controlled at 0.6-0.7. When dealing with the felling residues formed by thinning, the seedlings and saplings of Phoebe basilica should be avoided, and the method of combining the pile rot method or the scattered spreading method should be used; the pile rot method refers to the concentration of branches with a diameter of 5 cm and a length of more than 1 m. ...

Embodiment 2

[0023] A method for promoting the regeneration of Nannan natural forests, comprising the following steps:

[0024] (1) Selective thinning: In the first ten days of November, thinning was carried out on the natural forest stands of Phoebe macula with excessive density to improve the light conditions under the forest and eliminate the limitation of the growth of Phoebe mamba seedlings due to insufficient light under the forest. When thinning, cut down the old, sick and disabled individuals of non-Fujian species, so that the arbor layer space of the stand is evenly distributed 95-100m 2 The canopy density of the forest canopy is controlled at 0.6-0.7. When dealing with the felling residues formed by thinning, the seedlings and saplings of Phoebe basilica should be avoided, and the method of combining the pile rot method or the scattered spreading method should be used; the pile rot method refers to the concentration of branches with a diameter of 5 cm and a length of more than 1 ...

Abstract

The invention provides a method for promoting regeneration of a natural forest of phoebe bournei. The method comprises the following steps of (1) selective intermediate cutting, (2) land preparation and hole digging, and (3) seedling planting. In the natural forest of phoebe bournei, artificial auxiliary measures are adopted to promote the regeneration of the natural forest of phoebe bournei, notonly are a stand structure and understory illumination conditions improved, the restriction of natural conditions on natural regeneration is overcome, but also a seedling bank of the regeneration of the natural forest is supplemented, the problem that regeneration individuals are lacking in the regeneration process of the natural forest of phoebe bournei is solved, and the conversion from phoebe bournei seedlings into phoebe bournei saplings is effectively promoted. The method for promoting the regeneration of the natural forest of phoebe bournei has the advantages that the method is simple, convenient and feasible, the cost is low, the natural regeneration of phoebe bournei can be promoted, and the social and ecological benefits are better.

Description

technical field [0001] The invention relates to a technology for promoting natural forest renewal, in particular to a method for promoting the natural forest regeneration of Nannan. Background technique [0002] Phoebe bournei is an evergreen tree of the genus Phoebe in the family Lauraceae. It is a unique tree species in China and a national second-level key protected wild plant. Its trunk is straight, the wood structure is fine and dense, the cut surface is smooth and beautiful, and it has a fragrance. It is a precious material for high-grade buildings, furniture, carvings and precision wood models. The largest type of material. Minnan is mainly propagated by seeds, and the fruiting shows an obvious phenomenon of "big and small years". Due to the combined effects of human factors and habitat limiting factors, wild resources are decreasing day by day and are already in an endangered state. [0003] Minnan has a large amount of natural fruiting, but the germination rate o...
