Problems solved by technology

As a substitute plant, Emperor Bamboo Grass has the following risks that cannot be ignored: 1. Some species of exotic plants of the Poaceae Pennisetum genus have been listed as invasive species by some countries, and Emperor Bamboo Grass as a hybrid species is more dangerous. There is a great potential safety hazard, because the emperor bamboo grass is a kind of exotic plant with a height of 4-6 meters and a rhizome that can form intertwined roots in a 60-centimeter soil layer. While replacing the invasion of Eupatorium adenophorum, it also It will cause serious adverse effects on the development and renewal of the forest, and even bring about ecological disasters that are more harmful than Eupatorium adenophorum; The consequences will be disastrous

Embodiment 1

[0019] Embodiment 1. Eupatorium adenophorum removal treatment technology before alternative management of star hair chickweed

[0020] The experimental ecosystems include the following four types: Dahei Mountain, Wuben Township, Renhe District, Panzhihua City, Sichuan Province, belongs to the sparse forest with a canopy coverage of less than 70% (including 70%); most of the mountainous areas in Pingdi Town, Renhe District, Panzhihua City, Sichuan Province It belongs to the shrubs and sparse shrubs and grasses mainly composed of shrub species; due to deforestation, mining, road construction, and agricultural land abandonment, the barren hills and wastelands mainly suitable for forests are herbaceous plants; Yanyan 108, Renhe District, Panzhihua City, Sichuan Province Road area ecosystem composed of weeds, shrubs and young trees on both sides of national roads and roads at all levels. They were named A, B, C and D type test sites respectively.

[0021] In the above-mentioned ec...

Embodiment 2

[0023] Embodiment 2. The introduction and planting technology of Chickweed star hair

[0024] Taking the type A test site as an example, describe the introduction of Chickweed star hair into the ecosystem for planting. In the A-type test site after Eupatorium adenophorum was removed in step 1, 1600 square meters were selected for the introduction planting test of Chickweed. Divide the selected 1600 square meters into 4 plots named Aa, Ab, Ac and Ad respectively. Among them, the Aa, Ab, and Ac test sites used the following three planting methods to introduce the planting of the star-haired chickweed, and the Ad test site did not introduce the planting of the star-haired chickweed as a control.

[0025] 1. Introduction and transplantation of Chickweed star hair

[0026] The introduction and transplantation of Chickweed star hair is carried out from the end of June to the middle of July of the following year after Eupatorium adenophorum is cleared. In Aa, the test site is dug ...

Embodiment 3

[0037] Example 3. Ecosystem Management Techniques

[0038] After transplanting or cutting of Chickweed star hair in step 2, in the period of 1 to 2 months in the early stage of seedling growth, in view of the weak characteristics of Chime weed star early growth, it is necessary to maintain a certain density of upper plants to ensure the necessary Shade, and often remove Eupatorium adenophorum to prevent the adverse effects of excessive denseness of Eupatorium adenophorum on the development of chickweed seedlings. When the vines of chickweed starlings reach 50 cm in length and start to branch, the It can start to exert its advantage of occupying the ecological niche in the dry season, and inhibit the re-invasion of Eupatorium adenophorum.

[0039] In addition, human activities that are not related to ecosystem management, especially grazing, must be strictly prohibited in the sites of alternative management of chickweed, because the trampling of livestock when feeding will have...

Abstract

A method for preventing the intrusion of Eupatorium adenophorum to local ecological system features that the Stellaria vestita is planted to suppress the germination of the seeds of Eupatorium adenophorum and the growth of its seedlings.

Description

technical field [0001] The invention relates to a method for preventing and containing Eupatorium adenophorum from invading the ecosystem. Background technique [0002] Due to the rapid development of modern science and technology, especially the increasingly developed and convenient transportation, the long-distance and efficient transmission of some biological species has become a reality, which has led to the current global ecological disaster-biological invasion. In my country, exotic harmful plants such as Eupatorium adenophorum have invaded vast areas of our country, crowding out native plants, forming dominant populations and dense shrub cover, making it impossible for forests to regenerate naturally, and seriously destroying the structure and quality of my country's ecosystem. Function, has brought serious harm to the ecological environment of some regions. At the same time, the branches and leaves of Eupatorium adenophorum are obviously toxic to humans and livestock...
