Description

The method of cultivation ramie prevention and control Alien Weeds invasion
Technical field
The present invention relates to plant field, specifically, relate to a kind of method of cultivating ramie prevention and control Alien Weeds Ageratum conyzoides and Solidago Canadensis invasion.
Background technology
Exotic plant invasion has become global ecological problem.Ageratum conyzoides ( Ageratum conyzoides) and Solidago Canadensis ( Solidago canadensis) be two kinds of external malignant weeds that influence is big.Ageratum conyzoides originates from South America, and Solidago Canadensis originates in the North America, and both are big at China's generating capacity, and harm is heavy.These two kinds of Alien Weeds can produce and discharge multiple allelochemical, have the allelopathy effect; Spread in a large number in places such as farmland, orchards, influence the g and D of crop, cause the underproduction; Owing to annidation is wide, the growth of inhibition native country plant and other plant, the invasion ground formation list of being everlasting is excellent or be total to excellent group, and ecotope and social economy are brought harm.Remove a large amount of man power and materials of these malignant weed spends.
Prevention and control Alien Weeds common method mainly contains three types: artificial control's methods such as burning, excavate is adopted in (1), and these class methods only are applicable to control small size Alien Weeds.(2) utilize chemical control method such as weed killer herbicide, as preventing and kill off Solidago Canadensis with glyphosate, but this mode large tracts of land use, but a large amount of weed killer herbicides that use pollute the environment, and possibly damage human body.(3) measure of biotic control, as utilize dodder ( Cuscuta campestris) parasitic control Mikania micrantha ( Mikania micrantha), biological prevention and control method is applicable to large tracts of land, but exists biological prevention and control agent that new the variation taken place after introduction and have potential risk.Artificial control's method and chemical control method are only effective at short notice.These three class methods all are by external strength prevention and control exotic plant.　　　
The ecological resistance is exactly the ecosystem when being interfered, and keeps its integrality and the ability that resists system degradation.From resisting denizen invasion aspects, ecological resist be exactly the ecosystem under biotic factor and abiotic component effect, resist denizen invasion interference, keep its stable ability.The invasion of ecological resistance denizen is the ecosystem self has the invasion of resisting because of its inherent characteristic a ability.The ecological technology that resists stresses that ecosystem dependence self strength resists the denizen invasion.
The ecological mechanism that resists the denizen invasion comprises biomechanism and two aspects of abiotic mechanism.(1) biomechanism has following several respects: 1. the denizen growth is searched for food, limited to biology selectively.2. the plant secretion allelochemical suppresses exotic plant, as Japanese dodder ( Cuscuta japonica) to having of Mikania micrantha sense inhibitory action.3. plant competition property restriction exotic plant invasion, as perennial ryegrass ( Lolium perenne) competitiveness than Eupatorium adenophorum ( Eupatorium adenophorum) strong, available perennial ryegrass control Eupatorium adenophorum.(2) abiotic mechanism: disadvantageous temperature and soil characteristics, arid or the invasion of other interference-limited denizen.
Adopt the ecological technological prevention and control exotic plant invasion that resists, the most important thing is to select for use competitive strong eciophyte, to plant community transform or in the ecosystem of denizen invasion revegetation, make the ecosystem self have the ability that resists the denizen invasion.Ecological resistance technology is a kind of green technology, but large tracts of land is used and the invasion of long-time resistance control denizen.
In view of the few reason in the many arable lands of Chinese people, when the prevention and control denizen is invaded, take into account the utilization again in soil; Utilization again through the soil produces economic benefit, more helps the healthy and sustainable development of the maintenance rebuild ecosystem.
To the prevention and control problem of pernicious Alien Weeds Ageratum conyzoides and Solidago Canadensis, improve the soil through adding allogenic material, cultivating economic crop ramie ( Boehmeria nivea), make up the plant community that is suitable for ecological these two kinds of Alien Weeds invasions of resistance control, obtain certain economic benefits simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of method of cultivating the invasion of ramie prevention and control Alien Weeds; This method utilizes economic crops ramie resistance control Alien Weeds Ageratum conyzoides and Solidago Canadensis to settle down growth, and the ramie growth is fast, and adaptability is strong; Competitiveness is big, and has important economic worth.
