Abstract
A method for treating the intrusion of violet-stem eupatorium and controlling its extension features that the gynostemma pentaphyllum is planted in the woodland ecological system for biologically and ecologically suppressing and excluding the reproduction and growth of violet-stem eupatorium.
Description
Technical field
The method that the present invention relates to prevent and treat the exotic plant species invasion and spread particularly relates to and a kind ofly administers the Eupatorium adenophorum invasion and control the method that it spreads.
Background technology
Eupatorium adenophorum originates in Central America, is the perennial shrub of composite family, and plant height reaches about 100cm, and stem is upright, base portion multi-branched and be the shape of growing thickly.Eupatorium adenophorum happiness light, but certain anti-shady ability is arranged; Happiness is wet, but drought-resistance ability is extremely strong, can vigorous growth under multiple environment.More than 30 countries and regions that comprise China mainland and Taiwan Province have at present suffered its invasion danger.The branches and leaves of Eupatorium adenophorum have tangible toxicity to people and livestock, and the seed that the people sucks barbed pappus can cause symptom such as diarrhoea, asthma, the rotten to the corn stream of nasal cavity is dense; The seed that barbed pappus was eaten or sucked to livestock by mistake can cause multiple diseases such as pneumonia, reduces economic worth, loses the usage function, even cause death.Horse is injured especially serious, " the Wu Ma county " that cause the horses death ray because of the Eupatorium adenophorum invasion occurred in the mostly suffered area, Yunnan Province.
The four seasons temperature difference is little in China southwest, and the autumn and winter are arid season.In the autumn and winter arid season, annual herbaceous plant is withered, perennial plant and the trees dormancy of also usually falling leaves, but Eupatorium adenophorum can continue vigorous growth in dry season, and this is for madness invasion of Eupatorium adenophorum and spread suitable ecotope is provided.In case invasion, Eupatorium adenophorum will grow rapidly, the advantage that takes up space very soon (Eupatorium adenophorum under sparse woods highly usually between 80-150cm), squeeze original plant, become the excellent species of list of undergrowth, make forest ecosystem lose the ability of natural regeneration, and cause the serious forfeiture of ecosystem bio-diversity.In addition, because the special odor that the Eupatorium adenophorum leaf has livestock such as cattle and sheep to dislike, even do not become as yet Eupatorium adenophorum under the situation of advantage species, domestic animals such as ox, sheep, horse optionally gnaw local other native country plants, objectively also played and quickened the effect of native country plant atrophy even disappearance, thereby helped to strengthen the competitive advantage of Eupatorium adenophorum.
In south China, the forest canopy cover degree is one of main ecosystem-type of Eupatorium adenophorum invasion at the open forest land below 70%.CAS Botanical Institute 2003 is in south China Yunnan, Guangxi, when investigating Eupatorium adenophorum invasion situation, ground such as Guizhou find mostly to be the open forest land of 30%-60% in Yunnan, river Qi wood (Alnus ferdinandi-coburgii) and pinus yunnanensis (Pinus yunnanensis) forest canopy cover degree, Yunnan, river Qi wood is the open forest land of 30%-50% with walnut (Juglans regia) forest canopy cover degree, the forest canopy cover degrees such as open forest land that secondary evergreen broad leaved and deciduous broad leaved mixed forest forest canopy cover degree is 50%-70% are almost completely covered by Eupatorium adenophorum at the open forest land below 70%.At these Eupatorium adenophorum areas of coverage, only find the shrub that those are taller and bigger, as Daphne Giraldii Nitsche (Daphne sp.), butterflybush flower (Buddleja officinalis) and Herba Hyperici Patuli (Hypericum patulum), reaching happiness dark and damp herbaceous plant tooth calyx garden balsam (Impatiens dicentra), palm Begonia pedatifida (Begonia pedatifida), leaf of bamboo (Strepolirion volubile), dayflower (Commelinacommunis), lemon balm (Melissa axillaris) etc. has fragmentary distribution.
The solid amount of Eupatorium adenophorum is very big, ten thousand of the solid 20-100 of average every strain; Seed is extremely light, and thousand kernel weight only has the 0.04-0.045 gram, and has pappus, long very easily with the wind propagation.Although be put to huge effort aspect opposing and the invasion of improvement Eupatorium adenophorum both at home and abroad at present, but still do not have so far efficient ways (Yang Rongxi. endanger serious exotic invasive plant---Eupatorium adenophorum. biology circular, 2003,38 (1), 20-21).On the soil after a lot of improvement of south China, Eupatorium adenophorum is invaded once more, has wasted great amount of manpower, financial resources and material resources, but still is difficult to resist and administer the madness invasion of Eupatorium adenophorum.In Yunnan in China west and south, successively there is the report of distribution provinces and regions such as Guizhou, Guangxi, Sichuan, Chongqing, Hubei, Tibet, particularly in Yunnan, Guizhou, Guangxi and Sichuan harm is serious, and at present still with every year about 60 kilometers speed upcountry expand (Yang Rongxi. endanger serious stranger and invades plant---Eupatorium adenophorum. biology is circulated a notice of, 2003,38 (1), 20-21).The new technology that searching can be controlled invasion of noxious plant Eupatorium adenophorum and harm effectively is extremely urgent.
It is one of important measures of control and improvement exotic plant invasion that species substitute, and its principle is to utilize the high species of ecological security to occupy the ecological niche of invasive species, controls and squeezes the growth of denizen, thereby reach the purpose of resisting and administering exotic plant invasion.But the employed alternative floristics of China is nearly all from external introduction at present, a lot of true so alternative threats that exist new alien species invasion that illustrated, and its control efficiency also has been subjected to general doubting, and is worthless improvement method.For example, recently the domestic people of having advises adopting a kind of crossbreed hybrid giant napier of external grass family Pennisetum of introduction (Pennisetum purpureum * P.typhoideum) substitutes Eupatorium adenophorum (Zhang Zhengwen, open snow to the greatest extent. the Guizhou animal and veterinary, 2003,27,4-5), but hybrid giant napier plant as an alternative has following danger and shortcoming is not allowed to ignore: 1. some kinds of the crossbreed hybrid giant napier of exotic plant grass family Pennisetum are classified as invasive species by some countries, come in case spread, hybrid giant napier will be " the rice grass " of China's western region inland region undoubtedly.Even more serious is that hybrid giant napier is great disaster hidden-trouble in the withered grass phase of autumn and winter season (dry season), in case its consequence of catching fire is with hardly imaginable; 2. open forest land is one of main ecosystem-type of Eupatorium adenophorum invasion, but the hybrid giant napier of happiness light is difficult to growth under sparse woods, more can not form the needed alternative advantage of vicar; 3. growth is the intrinsic advantage that Eupatorium adenophorum can mad invasion during the withered grass in dry season autumn and winter, also can be withered during dry season autumn and winter but hybrid giant napier is the same with other plant, thereby during this hybrid giant napier to the growth of Eupatorium adenophorum without any inhibitory action; 4. even hybrid giant napier can be in some comparatively sparse sylvan life growths, but thisly can in the soil layer of 60cm, form deep-rooted exotic plant up to 4-6m, rhizome, when substituting the invasion of control Eupatorium adenophorum, also will cause harmful effect, even can bring than the bigger ecocatastrophe of Eupatorium adenophorum harm to growth and the renewal of forest.
Gynostemma pentaphyllum genus (Gynostemma) is under the jurisdiction of Curcurbitaceae, be the herbaceous perennial vine plant, like dark and damp environment, mainly be distributed in sylvan life at natural world circle, certain illumination condition and moisture are particularly arranged, and open forest land is the most common preferably, its growth characteristics be have that the elongated thin and weak and leaf area of stem is big, growth is fast and be positioned at all the time on the plant that it climbs up by holding on to, not withered dry season autumn and winter in China's southern subtropical, leaf such as can keep at characteristics.
Summary of the invention
The purpose of this invention is to provide a kind of safe and effective improvement Eupatorium adenophorum invasion and control the method that it spreads.
Improvement Eupatorium adenophorum provided by the present invention is invaded and controls the method that it spreads, and is to plant gynostemma plant in the sparse woods ecosystem.
Gynostemma plant commonly used has gynostemma pentaphylla (G.pennaphylla), light leaf gynostemma pentaphyllum (G.laxum), hair gynostemma pentaphylla (G.pubescens), Burma gynostemma pentaphylla (G.burmanicum), big fruit gynostemma pentaphylla (G.burmanicum var.molle), single leaf gynostemma pentaphyllum (G.simplicifolium), heart fruit gynostemma pentaphylla (G.cardiospermum), flower thinning gynostemma pentaphylla (G.laxiflorum) and longstipe gynostemma herb (G.longipes) etc.
There are three all method for planting to introduce gynostemma pentaphylla: 1) cuttage gynostemma pentaphylla rhizome or tendril: the seeding row spacing cuttage gynostemma pentaphylla rhizome or the tendril of pressing 20-60 * 30-80cm; 2) transplant seedling: the gynostemma pentaphylla seedling is transplanted by the seeding row spacing of 30-60cm * 50-80cm; 3) sowing seed: directly sow the gynostemma pentaphylla seed with the seeding row spacing of 20-60cm * 30-80cm.
Introduce the survival rate of gynostemma pentaphylla plant in order to guarantee, implantation time is the annual 3-11 month; Be preferably the annual 4-8 rainy season month.
For the quick ecological dominance of performance gynostemma pentaphylla plant, accounting in the sparse woods ecosystem of shrub layer absolute predominance Eupatorium adenophorum needs remove Eupatorium adenophorum with weed killer herbicide earlier before the plantation gynostemma pentaphylla.And do not account for the shrub layer absolute predominance and the sparse woods district of seedling just occurred Eupatorium adenophorum, can directly introduce gynostemma pentaphylla.
Weed killer herbicide commonly used has weed eradication cigarette, glyphosate or paraquat etc., is preferably glyphosate.
In order to guarantee the removing effect of weed killer herbicide, be the effective time of removing Eupatorium adenophorum in the 3-12 month in Eupatorium adenophorum growth busy season, the removing best results of the annual 4-8 month.
When the seedling tendril length of gynostemma pentaphylla does not reach 50cm and does not have branch, manually remove owing to remaining sprouting the Eupatorium adenophorum of being unearthed and growing rapidly, forbidding that people and livestock trample on, the smooth growth and the advantage that takes up space of being brought into play gynostemma pentaphylla the short period are very important in good time.
In the gynostemma pentaphylla cuttage or in time of the 1-2 month at growth of seedling initial stage after planting, at the more weak characteristics of gynostemma pentaphylla seedling, often remove seedling weeds on every side to prevent the too dense harmful effect that the gynostemma pentaphylla seedling development is caused of weeds, when gynostemma pentaphylla seedling tendril length reaches 50cm and begins branch, can let alone to coexist with other plant.In addition, in stage that gynostemma pentaphylla does not play a role as yet. the irrelevant human activity of other and ecosystem management as felling, dig medicine, cut firewood, dig medicine, cut into a mountain fetch earth stone, go hunting etc., all need strict restriction, particularly herd activity.Because gynostemma pentaphylla is one of herbage of cattle and sheep happiness food, herding not only has the very big pressure of measuring food of being crossed to gynostemma pentaphylla, pulling out when getting food pull and trample on also will to gynostemma pentaphylla survive and growth causes harmful effect.So it is fatal herding the influence that the alternative Eupatorium adenophorum of gynostemma pentaphylla is administered. behind plantation gynostemma pentaphylla plant, sylvan life is herded all the time and will firmly be forbidden.
Eupatorium adenophorum can be mad invasion China be because its seed is extremely light and have pappus, can grow propagation with the wind; And its seedling can be in China dry season autumn and winter, and promptly most of withered grass phase when withered of other original plants still can grow, and the advantage that takes up space rapidly.But its biology and ecological defective are that shade tolerance is limited.The inventor finds when the upper strata vegetation coverage arrives 80% the undergrowth of Eupatorium adenophorum in Yunnan, during the west and south community survey of China such as Guizhou, Guangxi; When the upper strata vegetation coverage reaches 90% when above, original Eupatorium adenophorum atrophy does not find that new Eupatorium adenophorum seedling occurs.
The present invention is directed to biology and the ecological characteristics of Eupatorium adenophorum, from China's endemic species, filter out the vicar of gynostemma pentaphylla, do not have the problem of ecological safety aspect as Eupatorium adenophorum; When gynostemma pentaphylla grows to 50cm and after beginning branch, can resist with Eupatorium adenophorum under field conditions (factors) fully, and the advantage that can take up space rapidly, formation almost is 100% covering on the shrub layer of sylvan life, can reach the purpose of resisting and administering the Eupatorium adenophorum invasion in open forest land permanently, effectively; Used plant gynostemma pentaphylla still is a kind of traditional Chinese medicine, has higher economic value, is an effective way that realizes the fast quick-recovery of Eupatorium adenophorum severely afflicated area economy.
The present invention utilizes the growth vigor of gynostemma pentaphylla to suppress and squeezes breeding and the growth of Eupatorium adenophorum, improves the ability of the sparse woods ecosystem self opposing Eupatorium adenophorum invasion, and effect is obvious, and the ecological security height has application value widely.
Embodiment
Embodiment 1, employing cuttage gynostemma pentaphylla (G.pennaphylla) planting technology control Eupatorium adenophorum
1, the sparse woods treatment technology before species substitute
Accounting in the open forest land of shrub layer absolute predominance Eupatorium adenophorum below 70% in the forest canopy cover degree, the growth busy season (May is to November) Eupatorium adenophorum sprays the Eupatorium adenophorum in the sparse woods with the high-efficiency low-toxicity herbicide glyphosate aqueous solution (41% glyphosate isopropyl amine salt aqua thin up to 60-120 doubly), treats that the whole withered backs of Eupatorium adenophorum (needing 15-20 days) are with its removing.Notice that when herbicide spraying the original plant that some is belonged to the native country all remains as much as possible.
