Problems solved by technology

For example, physical control is time-consuming and laborious; chemical control is not durable and may cause environmental hazards; although community transformation can be effectively controlled for a long time, the effect is slow, and the initial maintenance cost is high.
In biological control, dodder control has lag, and the infection effect is not good in the second year after overwintering; insect control is still in the laboratory stage, and the control effect, field safety and colonization ability have not yet been concluded

Embodiment 1

[0029] From March 2008 to December 2009, the inventor carried out the Mikania micrantha community improvement and prevention project in the secondary forest where Mikania micrantha was seriously damaged in Taojin Mountain, Shenzhen. In December 2007, the coverage of Mikania micrantha was greater than 80%, and the coverage of other grasses was about 8%. From March to April 2008, before the community transformation, the project site was treated for site preparation, and all Mikania micrantha and other weeds in the project site were removed by means of artificial physical eradication. From May to July 2008, community transformation trees were successively planted, such as Hainan rosewood, Yinxiang, sycamore, Macadamia, and Huangtong. Since the seeds of Mikania micrantha and other herbaceous plants in the soil could not be removed during site preparation, during the one-year tending and management process from August 2008 to August 2009, the regeneration of weeds and Mikania micra...

Embodiment 2

[0032] In August 2010, the inventor set up three plots of 5m×5m in a wasteland heavily covered by Mikania micrantha near the Zhongcun Nursery in Guangzhou, and the coverage of Mikania micrantha exceeded 90%. In March 2011, the aerial and underground parts of Mikania micrantha were completely cleared in the sample plots, and seeds of three different grasses, bermudagrass, crabgrass and weeding weeds, were sown in the three sample plots. In April, there was plenty of rain, and the seeds of Mikania micrantha and grasses germinated and grew well. The seedlings of Mikania micrantha in the sample plot were cleared once by artificial removal, and then the plants in the sample plot were allowed to grow naturally. After 2 months, the coverage of herbs in the sample plots exceeded 95%, the coverage of crabgrass and weeding bamboo plots both exceeded 80%, and the coverage of Mikania micrantha was less than 10%; The coverage of tooth root is only about 50%, the coverage of other weeds is ...

Embodiment 3

[0035] From 2015 to 2016, the inventor carried out a comprehensive control project of harmful vines in Neilingding Island, Shenzhen. Control plots were set up in the mixed hazard area of ​​Mikania micrantha and A. quinquefolium near Dongwan Wharf of Neilingding Island, and in the mixed distribution area of ​​micrantha, A. quinquefolium, S. chinensis, and thorny fruit vines near Jiaokeng Bay. From June to October 2015, chemical derusting agents such as Ziweiqing and fenfenling were used to remove harmful vines in the Dongwan plot. From November to March of the next year, continuous investigation and monitoring found that the plant regeneration status in different locations in the plot Significant difference, about 20m to the west of the plot 2 The range is almost completely covered by weeding bamboos, and the recovery rate of Mikania micrantha and A. quinquefolium is less than 5%; the east side of the plot is about 50m 2The revival rate of Mikania micrantha and C. quinquefoliu...

Abstract

The invention discloses a harmful vine comprehensive prevention and treatment method suitable for a secondary forest. The method comprises the following steps of: S1: removing a target harmful vine ona forest gap or a forest edge open space of the secondary forest; S2: intensively planting grass plants in a clean plot formed after the harmful vine is removed in the S1; and S3: carrying out woodyplant community transformation in a grass community distribution area formed by intensive plantation in the S2 to realize closing and forest establishment, and finally, forming a habitat which is notsuitable for the harmful vine and other weeds to live so as to prevent and treat the growth of the harmful vine. According to the method disclosed by the invention, an early succession species of a grass plant community which can quickly grow and is easy in manual management can be used for quickly occupying the habitat, a regeneration rate of the harmful vine is greatly lowered, and therefore, the problem that pure physical and chemical prevention and treatment needs to be repeatedly implemented for multiple times is solved. Meanwhile, the woody plant community transformation is carried out on a plot where the grass plants are distributed to form the habitat which is not suitable for the harmful vine to grow, and a purpose of long-term effective prevention and treatment can be achieved.

Description

technical field [0001] The invention relates to the technical field of ecological prevention and control of harmful plants, and more specifically relates to a method for comprehensive prevention and control of harmful vines suitable for secondary forest land. Background technique [0002] Lianas are a kind of non-natural taxa that cannot stand upright freely after growing to a certain height, and rely on climbing other plants or objects for support. Lianas have a "locomotor" function, with their tendrils or stems stretching, winding, and climbing toward potential supports through a spiraling motion, ultimately gaining more resources and space for growth. Lianas differ from other epiphytic / parasitic plants with climbing or twining habits in that the nutrients they need for growth come directly from the soil. Researchers generally divide vines into herbaceous vines and woody vines. Woody vines play an important role in tree growth and regeneration, maintenance of species dive...
