Problems solved by technology

This method does not take into account the influence of the canopy density of the S. apetalum forest on the growth of Lavender, and it takes a long time to form a multi-layered stand with a complex structure to increase biodiversity and improve the stability and protective effect of the system.
This method does not control the canopy density of the mulberry crown community through girdling technology, and obtains a light environment suitable for the survival and development of Lavender and Tung flower trees, so that it is impossible to obtain a mangrove community with a complex structure in the shortest time, and speed up the development of the Apetalum mulberry community. The process of rural transformation of Haisang community

Embodiment 1

[0029] (1) Pretreatment of the understory herbaceous layer in the plantation of Sangria apetalum: remove the roots of mangrove plants in the herbaceous layer, such as acanthus sylvestris and brine fern, and prepare the seedlings of native mangrove olive and tung tree Provide good growing conditions.

[0030] (2) prepare the saplings of olive and tung tree: cultivate 1-year-old sapling and bag seedling of tung tree in the nursery, the height of the seedling is about 50-70cm, the seedlings are robust and free from damage by diseases and insect pests;

[0031] (3) Treatment A of the canopy transformation of Sonangria apetala plantation (such as figure 1 ): Girdling transformation A treatment is carried out in the artificial forest of Sangulis apetalum, that is, girdling one tree at intervals of 3 trees along the direction perpendicular to the river channel, and the girdling accounts for about 25%. Carry out bark girdling at 50cm-150cm, girdling width is 100cm, remove all bark, e...

[0037] (1) Pretreatment of the understory herbaceous layer in the plantation of Sangria apetalum: remove the roots of mangrove plants in the herbaceous layer, such as acanthus sylvestris and brine fern, and prepare the seedlings of native mangrove olive and tung tree Provide good growing conditions.

[0038] (2) prepare the saplings of olive and tung tree: cultivate 1-year-old sapling and bag seedling of tung tree in the nursery, the height of the seedling is about 50-70cm, the seedlings are robust and free from damage by diseases and insect pests;

[0039] (3) Treatment B of Sonneratia apetalum plantation canopy improvement (such as figure 1 ): Girdling transformation B treatment is carried out in the artificial forest of Sonus apetalum, that is, girdling one tree at intervals of 2 trees along the direction perpendicular to the river channel, and the ratio of girdling is about 33%. Carry out bark girdling at 50cm-150cm, girdling width is 100cm, remove all bark, expose xylem)...

Embodiment 3

[0045] (1) Pretreatment of the understory herbaceous layer in the plantation of Sangria apetalum: remove the roots of mangrove plants in the herbaceous layer, such as acanthus sylvestris and brine fern, and prepare the seedlings of native mangrove olive and tung tree Provide good growing conditions.

[0046] (2) prepare the saplings of olive and tung tree: cultivate 1-year-old sapling and bag seedling of tung tree in the nursery, the height of the seedling is about 50-70cm, the seedlings are robust and free from damage by diseases and insect pests;

[0047] (3) Treatment C of the canopy improvement of Sonangria apetala plantation (such as figure 1 ): Girdling transformation C treatment is carried out in the artificial forest of Sonus apetalum, that is, girdling one tree at intervals along the direction perpendicular to the river channel, and the ratio of girdling is about 50%. Carry out bark girdling at 50cm-150cm, girdling width is 100cm, remove all bark, expose xylem), 6-8 ...

Abstract

The invention provides a method for promoting succession of a sonneratia apetala artificial forest to a native community. The method specifically comprises the following steps that (1) an under-forestherbal layer of the sonneratia apetala artificial forest is pretreated, specifically, root cutting removal treatment is carried out on the under-forest herbal layer of the sonneratia apetala artificial forest; (2) native mangrove seedlings are prepared, specifically, the annual native mangrove bag seedlings are cultivated; (3) canopy transformation treatment is carried out on the sonneratia apetala artificial forest, specifically, trunk girdling treatment is carried out on the sonneratia apetala artificial forest, and pruning treatment is carried out in an assisted mode to reduce canopy density of canopies; (4) the native mangrove seedlings are planted, specifically, the native mangrove bag seedlings are planted, and the seedlings are supported, fixed and reinforced; and (5) transformation measures are screened, specifically, the seedling preservation rate and the seedling height increment are investigated. According to the method, the under-forest light transmittance is increased through an interval sonneratia apetala trunk girdling technology, the two shade-tolerant native arbor species, namely, the bruguiear gymnorrhiza and the aegiceras corniculatum, are introduced, and a multi-layer forest community can be formed, so that the sonneratia apetala artificial forest gradually successes to the native arbor mangrove forest community.

Description

technical field [0001] The present invention relates to a method for promoting the succession of exotic mangrove plant Sangria apetalum artificial forest to the native community, which is a method of using native mangrove plants——Sorbus apetalum and Tung flower tree to carry out the artificial forest of exotic fast-growing tree species Sangulus apetalum Methods for community structure modification. Background technique [0002] Mangrove communities are one of the important types of wetlands in coastal areas, and have important social, economic and ecological values. The three provinces (districts) of Hainan, Guangdong and Guangxi account for more than 80% of the national mangrove area, of which Guangdong Province is the province with the largest mangrove distribution area in the country. .) The plantation area is 2082 hectares, accounting for 17.29% of the province's mangrove area. In addition, Hainan, as the first introduction place of Sangria apetalum, has a large area d...
