Description
Technical field
The present invention relates to invade malignant weed and administer the field, relate to particularly a kind of method of utilizing the hybridization napier grass to substitute the pernicious invasive weed artemisiifolia of control.
Background technology
Artemisiifolia (Ambrosia artemisiifolia L.) is a kind of pernicious invasive weed, and its harm is mainly reflected in four aspects such as vector that jeopardize human health, the production of destruction farming and animal husbandry, destruction endemic plant diversity and balance of nature and can be used as some damage by disease and insect.It is former that the pollen that artemisiifolia produces is that human pollen hypersensitivity symptom (hay fever, also claim pollinosis) main causes a disease, and causes the reaction diseases such as allergic dermatitis and bronchial astehma, thereby cause human health to be endangered.According to the data record, the U.S. approximately has 1,470 ten thousand people to suffer from pollinosis every year, and crowd's incidence of disease reaches 2～15%, and its medical expense is up to 600,000,000 dollars.In more American-European countries, artemisiifolia has a strong impact on city and outskirts of a town (such as Canadian Quebec City) resident's living environment, and Countries (such as Switzerland) rises to Control Ambrosia the height of law, and remove artemisiifolia the every year of mobilizing the masses.
Artemisiifolia can mix and invade the vegetable field, orchard, mulberry field, nursery, pasture etc. of crops field (such as fields such as corn, soybean) and mismanagement, owing to having powerful root system and huge ground trophosome, raise crop and wild plant had obvious inhibitory action.Under the strong competition of artemisiifolia, crop failure is very serious, and research finds, when every square metre of the corn field of campaign has 10～15 strain artemisiifolia, and the corn underproduction 30～45%; Every square metre when 50～100 strain is arranged, can cause almost that No kernels or seeds are gathered, as in a year of scarcity, when the capable long soybean of 10m has 4 strain artemisiifolia, per hectare soybean underproduction 132kg; When Kidney bean was bloomed front 30d generation artemisiifolia, pod yield reduced 30%, and whole breeding time (50d), artemisiifolia occured, and then the underproduction 75%.The artemisiifolia late growing stage is very rapid, is enough to overwhelm other therophytes, and the soil of lording it over a district destroys Plant Diversity, makes structure of plant community simply and unification, thereby causes soil animal and insect society to change.Artemisiifolia is imported China's southeastern coast into about early 1930s greatly, and artemisiifolia sample the earliest sees botanical garden, Nanjing herbarium, and nineteen thirty-five adopts in Hangzhou.According to 1993, in Liaoning, the some areas in province (autonomous region) cities such as Jilin, Heilungkiang, the Inner Mongol, Hebei, Beijing, Henan, Shandong, Anhui, Jiangsu, Zhejiang, Jiangxi, Hubei, Hunan, Fujian, Guangxi, Guangdong, Shanghai, Sichuan, Guizhou and Tibet find artemisiifolia, and form Nanjing, Wuhan, three in Nanchang-Jiujiang and occur and dispersal center.1997, China just classified artemisiifolia as one of weeds of three class potential dangers.
It is the method that a kind of ecology is prevented and kill off invasive weed that plant substitutes, it also is a kind of restoration of the ecosystem measure, it is main that certain has the useful of stronger competitiveness or has the plant of economic worth and invasive weed to carry out interspecies competition by artificial culture, predation invasive weed space and the resource of depending on for existence, thus suppress the diffusion of invasive weed and spread.It is that weeds continue very effective technical measures in the improvement that plant substitutes.Given this, we have further invented and have utilized the hybridization napier grass to substitute the method for the pernicious invasive weed artemisiifolia of control on the basis of selecting the substituted plant (hybridization napier grass) with economic worth.
Summary of the invention
The purpose of this invention is to provide a kind of method of utilizing the hybridization napier grass to substitute the pernicious invasive weed artemisiifolia of control.
The method that utilization hybridization napier grass according to the present invention substitutes the pernicious invasive weed artemisiifolia of control comprises the step that substitutes the artemisiifolia plantation with napier grass.
The method according to this invention, preferred described napier grass is the hybridization napier grass.Selected hybridization napier grass is a kind of herbage with economic worth, and at He Ba, lie waste the heavy generating region plantations of the artemisiifolias such as ground, barren beach, can effect a radical cure this pernicious invasive weed of artemisiifolia grows, and reaches the purpose that Sustainable Control artemisiifolia population spreads.
The method according to this invention, preferably hybridize napier grass according to napier grass: artemisiifolia=1～3:1 kind is planted (plant spacing ratio).
The invention provides a kind of technology that the alternative pernicious invasive weed artemisiifolia of herbage hybridization napier grass of economic worth is arranged of utilizing, this technology not only can be optimized, beautify the environment, repairs the eciophyte diversity and be rebuild balance of nature, and sustainable artemisiifolia seed and the pollen source effectively controlled, reduce the hypersensitive ratio of population infection ragweed pollen, reach the effect of putting things right once and for all.
Embodiment
Embodiment 1
1, substituted plant is selected
The hybridization napier grass: select evenly healthy and strong acrial part cane, be divided into the fragment that evenly is cut into 20～30cm, every section cane keeps a node (being that bud grows from node).
2, the alternative planting patterns of hybridization napier grass
According to the characteristics that forage seeding is respectively the spring, all can sows in Xia Qiusan season period, the sowing that we select is two seasons of spring and summer.Carried out April 20～30 spring, and carried out June 10～25 summer.April 20～30, digged through topsoil is slightly done in first bud phase in the artemisiifolia many places, mainly is the grassy weed etc. that invests the soil table is removed.Then with above-mentioned hybridization napier grass according to napier grass: artemisiifolia=1～3:1 kind is planted (plant spacing ratio).June 10～25, artemisiifolia is in the phase of contain sending out, and can in advance the artemisiifolia plant be carried out the level land and cradle, and removes the grassy weed that invests the soil table equally, then with above-mentioned hybridization napier grass according to napier grass: artemisiifolia=1～3:1 kind is planted.Hybridization napier grass ratio is easier to survival, need not nurse especially.General plantation First Year, the hybridization napier grass is not obvious to the artemisiifolia substitution effect, therefore, to winter, need to the hybridization napier grass on the ground cane cut off, treat that underground perennial root germinateed voluntarily and formed new plant spring in next year.
3, the hybridization napier grass is to the substitution effect of artemisiifolia
Two season of spring and summer in 2009 plant hybridization napier grass will hybridize napier grass ground cane and cut off in winter in 2009, keep perennial root.On September 25th, 2010, the survey showed that: experience after 1 year, no matter be plantation in spring or plantation in summer, the hybridization napier grass all has significant inhibitory action to artemisiifolia.In the alternate area, plant substituted plant hybridization napier grass spring, can cause 81.3%～86.8% artemisiifolia plant death next year; Plant substituted plant hybridization napier grass summer, next year, artemisiifolia plant lethality was 80.4%～85.9% (table 1).
