Embodiment 1
[0020] During the daily management and maintenance of the plants in the growing area of Mikania micrantha, it was found that compared with other tree species that were heavily covered by Mikania micrantha, the number of climbing and entangled Mikania micrantha trees was less. Plant seedlings of different tree species under two years old (about 1.5m high) in the area where Mikania micrantha is endangered, and observe for a growing season. It is found that the top leaves of all young Macaranga tunga trees are not covered, the plants are growing well, and there is no death; The leaves are all covered, and only the top seedlings that grow vertically are on the covering layer. The growth is affected to a certain extent, and there is no death; the whole plant of Yinxiang saplings is covered, and the growth is slow, but there is no death; Occasionally, a small number of leaves exposed the cover layer of Mikania micrantha, the growth was inhibited, and the mortality rate of young tre...
Embodiment 2
[0023] In August 2010, a shelterbelt pilot project was carried out in the area near the reservoir on the south side of Dalingshan Forest Park in Dongguan. Extend 50 meters to both sides with the more severely damaged area as the center, and extend 15 meters from the bottom of the mountain to the top of the mountain, and trim the planting belt with a width of 50cm-60cm along the contour line. In the 6m range near the bottom of the mountain, the distance between the planting belts is 2m; within the range of 9m in the direction of the top of the mountain, the distance between the planting belts is 3m. In all ranges, the distance between plants was 2m. The arrangement of tree species is as follows: the three planting belts near the road at the bottom of the mountain are dominated by Macaranga tannica, and the mixed plantings of sycamore, yellow tung and yinxiang (see figure 2 ). In the two growing seasons after the afforestation project, the seedlings in the planting area were ...
