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
The present invention relates to a kind of preventing and/or the method for inhibiting violet berba lycopi to invade ecological system.
Background technology
Because the high speed development, particularly traffic of modern science and technology is flourishing and convenient day by day, makes the propagation of some biological species high-effect long distance rates become a reality, and has caused present global ecological disaster---biotic intrusion thus.In China, Eupatorium adenophorum Exotic Harmful Plants such as (Eupatorium adenophorum) is occupied the vast region of China, squeeze eciophyte, form dominant population and intensive shrub cover layer, make forest can't carry out natural regeneration, heavy damage the 26S Proteasome Structure and Function of China's ecosystem, brought serious harm for the subregion ecotope.Simultaneously, the branches and leaves of Eupatorium adenophorum have tangible toxicity to people and livestock, and the seed that barbed pappus was eaten or sucked to livestock by mistake can cause pneumonia, reduce the economic worth of livestock or cause it to lose the usage function, even cause death; The people sucks symptom such as the Eupatorium adenophorum seed can cause that also diarrhoea, asthma, nasal cavity erosion are suppurated.After the Eupatorium adenophorum invasion agricultural ecosystem, cause agriculture production cost raising and crop yield and quality to descend.Therefore, the invasion of Eupatorium adenophorum is a big obstacle of regional economy development.
Although both at home and abroad being put to huge effort aspect the invasion of improvement Eupatorium adenophorum, still do not have efficient ways so far at present.In Yunnan of China southwest, Guizhou, Sichuan, Guangxi, Chongqing etc. economize (district, city), though people make a very big effort improvements, Eupatorium adenophorum is invaded again easily once more on the soil after the improvement.So manpower, financial resources and material resources had both been wasted in circulation, and it is little to take effect again, made people lose the confidence of further improvement Eupatorium adenophorum invasion gradually.At present Eupatorium adenophorum China still with every year about 10～60 kilometers speed upcountry expand, it is extremely urgent obviously to seek the new technology that can prevent and/or contain invasion of noxious plant Eupatorium adenophorum and harm effectively in China.
Ecological niche vacancy in the ecosystem and instruction plant breeding, growth are that the plant invasion can two successful important prerequisites rapidly.With regard to a certain regional ecosystem itself, the ecosystem causes the impaired of ecosystem kind composition, space structure and systemic-function owing to being subjected to external interference, the ecological niche vacancy will appear, for Exotic Harmful Plants provides the space that can invade, in case invade successfully, they just squeeze local species by the mode of quick growth and breeding, form dominant population and the intensive excellent group of list, cause the forfeiture of local ecosystem bio-diversity.
In China southwest, the ecosystem-type that Eupatorium adenophorum can be invaded mainly concentrates on following four kinds: first kind is that the forest canopy cover degree is the sparse woods that (comprise 70%) below 70%; Second kind is to serve as the shrubbery and the sparse filling thick grass of main composition with the shrub kind; The third be because forest harvesting, open a mine, repair the roads, the no longer cultivated suitable for afforestation waste mountain waste that causes in agricultural land based on herbaceous plant; With the 4th kind be territory, the road ecosystem of forming with the treelet of weeds, shrub and arbor along the road both sides.At Sichuan Province's Panzhihua City, along both sides of highway at different levels and surrounding area, Eupatorium adenophorum usually forms the excellent group of intensive list in the scope of 1800～2400 meters of height above sea level, is the key area of control.
The Eupatorium adenophorum breeding is very fast, solid 20～1,000,000 of average every strain; Its seed is extremely light, and thousand kernel weight only has 0.04～0.045 gram, and has pappus, long very easily with the wind propagation.Simultaneously, vehicle pass-through and along the air-flow of road more the long-distance communications of Eupatorium adenophorum seed advantage is provided.On the other hand, the fit closely quick growth of the weather of China southwest, the Eupatorium adenophorum seed can germinate then, although beginning poor growth, dry season, general height of seedling was 5～30 centimetres, but after rainy season next year its quick growth period, its height relatively can reach 50～80 centimetres under the drought environment when arriving to next dry season, and under the more moistening condition of environment, highly reach 90～120 centimetres, every strain Eupatorium adenophorum can form the coverage of 30～80 centimetres of diameters, and reached sexual maturity, blossom and bear fruit.Triennial Eupatorium adenophorum promptly reaches the period of great prosperity, and the branch of each plant is tillered up to 100, and area coverage reaches 1 square metre, solidly reaches 50～800,000, and keeps the ever-increasing impetus in 5～8 years afterwards always.
In addition, below the reason of three aspects more help the invasion of Eupatorium adenophorum, and be difficult to after the invasion administer: 1. the autumn and winter are obviously arid because China southwest four seasons temperature difference is little, the annual herb plant that enters in the plant community in dry season begins withered, the dormancy of also usually falling leaves of herbaceos perennial and a lot of trees, but the Eupatorium adenophorum seedling that germinates in rainy season can keep growth always during dry season, thereby has occupied because the ecological niche vacancy that eciophyte is withered or resting stage causes; 2. in the variation of autumn and winter arid season owing to sun altitude, make that the place of insufficient light obtains good illumination originally, this grows for the Eupatorium adenophorum growth of seedlings and has brought opportunity; Eupatorium adenophorum has entered the high-speed rapid growth stage when rainy season, the eciophyte kind began germinating growth, sets up oneself " air superiority ", thereby makes own status of having the advantage in competition.We are referred to as " time difference effect " to this invasion phenomenon that difference on biorhythm causes owing to instruction plant and eciophyte, and Eupatorium adenophorum has utilized the constantly invasion of this time difference, and this makes improvement year after year not become effective; 3. because Eupatorium adenophorum has the special odor that herbivore dislikes, the trample of domestic animal and optionally gnaw eciophyte, objectively also play the effect of quickening the eciophyte atrophy, causing the ecosystem to be degenerated, thereby strengthened the competitive advantage of Eupatorium adenophorum.
It is one of important measures of improvement and containment exotic plant invasion that species substitute, its principle is to utilize the high local species of ecological security to occupy the ecological niche of invasive species, the growth of containment denizen is repelled denizen existence, thereby is reached the purpose of resisting and administering exotic plant invasion.But in China, employed alternative floristics is but nearly all from external introduction at present.A lot of facts have illustrated that so alternative improvement exists the threat of new alien species invasion, and its control efficiency also has been subjected to general doubting, thereby is referred to as " tiger is not driven at the Qianmen as yet away, and wolf has been introduced at the back door again ", is worthless.Recently domestic also constantly the someone advise adopting a kind of crossbreed hybrid giant napier of exotic plant grass family Pennisetum of introduction (Pennisetum purpureum * P.typhoideum) substitute Eupatorium adenophorum.Hybrid giant napier plant as an alternative has following danger and do not allow to ignore: 1. some kinds of exotic plant grass family Pennisetum are classified as invasive species by some countries, then has bigger danger as the crossbreed hybrid giant napier, exist very big potential safety hazard, because being 4～6 meters of a kind of Gao Keda, rhizome, hybrid giant napier can in 60 centimetres soil layer, form deep-rooted exotic plant, in alternative inhibiting violet berba lycopi invasion, also will cause serious harmful effect with renewal, even can bring than the bigger ecocatastrophe of Eupatorium adenophorum harm to the growth of forest; 2. hybrid giant napier is great disaster hidden-trouble in autumn and winter season (dry season), in case its consequence of catching fire is with hardly imaginable.
Summary of the invention
The purpose of this invention is to provide a kind of safe, effective, economic preventing and/or the method for inhibiting violet berba lycopi to invade ecological system.
Content of the present invention comprises: 1. the eciophyte that finds a kind of energy and Eupatorium adenophorum to contend with; 2. find a kind of effectively novel ecosystem management method, promote eciophyte and local other plant that this energy and Eupatorium adenophorum are contended with to bring into play ecological dominance together as early as possible, capture rapidly and for a long time and remove vacant lot or the easy vacant lot of invading of Eupatorium adenophorum that Eupatorium adenophorum occurs, can fundamentally resist the Exotic Harmful Plants Eupatorium adenophorum effectively the invasion of the ecosystem and the harm that causes.This patent finds that the eciophyte that energy and Eupatorium adenophorum are contended with is the star hair chickweed (Stellaria vestita) of Caryophyllaceae (Caryophyllaceae), utilizes star hair chickweed to substitute Eupatorium adenophorum, not only safety but also economy; This patent is also found, by novel ecosystem management method, can make star hair chickweed and local other plant together ramp and capturing for a long time remove the easily vacant lot of invasion of vacant lot that Eupatorium adenophorum occurs or Eupatorium adenophorum, can fundamentally resist of the invasion of Exotic Harmful Plants Eupatorium adenophorum effectively to the ecosystem.
Star hair chickweed is the perennial climing property herbaceous plant of Caryophyllaceae Stellaria (Stellaria L.), and wide geographic area all has distribution on the south China Huanghe valley reaches.Star hair chickweed stem is thin and delicate, and length can reach 1.5 meters or longer, the face of land or tiltedly stretch and depend on the other plant body of crawling.In China southwest, star hair chickweed is a kind of evergreen draft.
Evidence, pinkwort star hair chickweed be a kind of can dry season and Eupatorium adenophorum contends with and with Eupatorium adenophorum growth of seedling and competition for existence in occupy clear superiority kind, by introducing plantation and the in addition management of reasonable configuration and science, star hair chickweed can play a role in the ecosystem-type that Eupatorium adenophorum is invaded easily and invaded fully, thereby stop Eupatorium adenophorum to utilize " time difference effect " intrusion behavior in the seedling ramp in dry season and the advantage that takes up space effectively, administering for the sustainability that substitutes the external harmful species Eupatorium adenophorum invasion of control provides basic guarantee.
Star hair chickweed can with Eupatorium adenophorum competition in preponderate and mainly contain reason aspect following three: 1. star hair chickweed is in more anti-shade of the season of growth (rainy season), branch is elongated, blade is sparse, the color pale green, the fleece rareness, often depend on other plant limb and go up or be tiled in ground, its joint place on the contact face of land easily germinates adventive root; Arrive other plant when beginning withered death when dry season, star hair chickweed is at its base portion and had the joint place of adventive root to begin to grow the internode cripetura, blade is intensive, close by the shoot of canescence pubescence, formation is center, 30～60 centimetres of do not wait circular or oval of radius with the primary roots, can give the face of land with intensive covering; 2. star hair chickweed still can be kept intensive branches and leaves and withered in autumn and winter arids in season; Star hair chickweed concerning livestock because crinosity and palatability is very poor can be avoided gnawing of domestic animal effectively.
The present invention has following advantage: 1. star hair chickweed is as the kind that can contend with and take advantage with Eupatorium adenophorum, under alternative plantation of the present invention and administrative skill condition, can reach under field conditions (factors) in the whole year through the growth in 1～3 year, especially occupy very significantly space advantage in dry season, can prevent the phenomenon that Eupatorium adenophorum utilizes " time difference effect " to capture ecological niche effectively, through management and the support in 1 year, can reach the invasion of complete inhibiting violet berba lycopi and/or invasion more again.The ecosystem management aspect is as long as carrying out to forbid loosing on the basis of existing forest policy herds livestock afterwards, just can reach chronically, inhibiting violet berba lycopi invasion danger sustainably.2. there has been very strong resistivity in vegetation ecological system itself to Eupatorium adenophorum owing to grow preferably, so what occupy very big proportion in the zone of Eupatorium adenophorum invasion is some ecosystem-types such as sparse woods, waste mountain waste suitable for afforestation, shrubbery, territory, the road ecosystem, and the applicable object of the present invention disaster-stricken serious ecosystem-type that just in time is these, so have very strong specific aim.3. star hair chickweed is the local species of China, does not have the hidden danger of any ecological safety aspect, can keep in with other eciophytes, carries out the Eupatorium adenophorum invasion with it and substitutes improvement, helps the recovery of structure and the function and the bio-diversity of the ecosystem.4. although in dry season, the rainfall of the southwest short time of China even heavy showers almost all have generation every year, therefore are coated with the water and soil conservation that is beneficial to when meeting with precipitation dry season on the formed face of land of star hair chickweed in dry season.5. because the thickness of star hair chickweed covering in dry season is generally 5～10 centimetres, can stretch out or stretch out outside the cover layer very soon behind the seed sprouting of trees, so the renewal that the intensive face of land of star hair chickweed covers the forestry seeds can not impact.6. the present invention has been also for the zone that suffers Eupatorium adenophorum invasion easily provides prevention scheme, and particularly the environmental improvement after the engineering such as road construction is built with greening.
The alternative managemental experiment of Eupatorium adenophorum is shown by suitable implantation time, the rational management mode of planting patterns and science, star hair chickweed is planted in the ecosystem of above-mentioned Eupatorium adenophorum invasion, can reach the purpose of long-term sustainable inhibiting violet berba lycopi invasion.
Embodiment
Method among the embodiment is conventional method if no special instructions.Prevent and/or the technology of inhibiting violet berba lycopi to invade ecological system is one and removes Eupatorium adenophorum, introduces the integrated of plantation star hair chickweed and ecosystem management technology.The present invention describes in further detail by following embodiment,
The Eupatorium adenophorum that embodiment 1. star hair chickweeds substitute before administering is removed treatment technology
The ecosystem that experimentizes comprises following 4 kinds: Panzhihua City Renhe District big Black Hills, township of attending to the basic or the fundamental in Sichuan Province's belongs to the forest canopy cover degree the sparse woods that (comprise 70%) below 70%; It is main shrubbery and the sparse filling thick grass of forming that most of mountain region, Panzhihua City Renhe District level land, Sichuan Province town belongs to the shrub kind; Because forest harvesting, open a mine, repair the roads, the no longer cultivated suitable for afforestation waste mountain waste that causes in agricultural land based on herbaceous plant; Territory, the road ecosystem that Sichuan Province's Panzhihua City Renhe District is formed with the treelet of weeds, shrub and arbor along 108 national highways and both sides of highway at different levels.They are named as A, B, C and D type respectively experimental field.
In the above-mentioned ecosystem that Eupatorium adenophorum has had comparative advantage, September in growth busy season of Eupatorium adenophorum to October, with the high-efficiency low-toxicity herbicide glyphosate aqueous solution Eupatorium adenophorum is sprayed, treat the whole withered backs of Eupatorium adenophorum (20～30 days) in time with its removing, the way of removing is manually to pull out and be transported to the safety area to burn or be used as fuel.Because Eupatorium adenophorum is intensive, some eciophytes that grow under it generally can not be subjected to poisoning, so when removing withered Eupatorium adenophorum, as much as possible these eciophytes are all remained.
Also used weed killer herbicide weed eradication cigarette and paraquat to substitute glyphosate respectively in the test, alternative result is: the weed eradication cigarette can all kill Eupatorium adenophorum, but in soil, leave residual hazard, cause after the dispenser that nearly all plant all can't survive in time of 4～6 months, make that the star hair chickweed survival rate of introducing plantation is very low maybe can't survive; Paraquat can only kill leaf and the spray of Eupatorium adenophorum, and can not make Eupatorium adenophorum all dead, does not have due kill activity.
The introducing planting technology of embodiment 2. star hair chickweeds
With the A type experimental field is example, describes being introduced in the ecosystem of star hair chickweed and plants.To in step 1, remove behind the Eupatorium adenophorum the A type experimental field in, select 1600 square metres of introducing planting experiments that are used for star hair chickweed.To select 1600 square metres and be divided into 4, be respectively called after Aa, Ab, Ac and Ad experimental field.Wherein Aa, Ab, Ac experimental field introduce plantation star hair chickweed with the kind method for planting of following three kinds of star hair chickweeds, and Ad does not experimental field introduce plantation star hair chickweed in contrast.
1, the introducing implantation technique of star hair chickweed
The next year of the time that the introducing of star hair chickweed is transplanted after removing Eupatorium adenophorum by the end of June～carry out mid-July.At Aa, experimental field the seeding row spacing by 30 centimetres of 5 cm x, 10 centimetres～10 cm x digs the cave, the degree of depth in cave and diameter are 8～15 centimetres, digging the back fills up the cave with face of land humus soil, open humus soil with little spade in gardens or hand-lifting then, with the star hair chickweed root back earthing that is placed in one, make itself and face of land maintenance smooth.Transplanting success reaches 100%; The transplanting in dry season will be watered immediately after transplanting and be kept ground moistening 20～30 days, and survival rate reaches more than 85%.Star hair chickweed connects promptly has new root to grow and the shoot germination after root transplanted for 1 week, and 1 month begins the growth of climing property, and tendril length reached about 50 centimetres in 3～5 months, and arid season comes just can form diameter and is canescence and intensive face of land covering for about 50 centimetres temporarily.
2, the cuttage and seedling culture of star hair chickweed is introduced planting technology
1) cuttage and seedling culture of star hair chickweed
Because star hair chickweed fruit is very little, the maturing stage is inconsistent, and ripe back shell cracking seed very easily is scattered, and plucks relatively difficulty, so adopt the method for cuttage to grow seedlings.Though cuttage survives easily, but because star hair chickweed branch is thin and delicate, though it is higher to carry out cuttage survival rate separately, survive back early stage growing way a little less than, concentrating grows seedlings helps bringing into play as early as possible after the managing and protecting in early days and transplant of star hair chickweed seedling the effect of inhibiting violet berba lycopi invasion.
Gather its branch in the star hair chickweed growth busy season, and in time its line-spacing by 5～10 centimetres is carried out cuttage in the nursery, that is: the whole branches with star hair chickweed is tiled on the ground, seedbed according to the trend of going, and the internode distance of star hair chickweed is the spacing in the rows of seedling.Complete 0.5～1 centimetre of back earthing, note behind the earthing and the blade of star hair chickweed must be exposed, water with sprayer again.Shading shed will be taken in the top, seedbed, and the intensity of shading is 70～85, and is withered in order to avoid strong direct sunlight causes water balance imbalance in the star hair chickweed body.According to the humidity conditions of soil, keep ground moistening with sprayer or watering can, left and right sides star hair chickweed will produce adventive root at its each joint place in 10 days, and axillalry bud also begins to sprout.When the bud for the treatment of New Development about 1 month grows 5 centimetres of left and right sides, available cutter will be embedded in that the old branch of star hair chickweed cuts off to promote independent separately the growth in internode under the face of land after 2 months.Through above-mentioned processing, new independent plant of each joint bud into of star hair chickweed branch, survival rate is 80%～98%.
2) transplanting after star hair chickweed is grown seedlings
After the growth of star hair chickweed seedling through a season of growth of nursery cuttage, the climing length of stem can reach about 10 centimetres, and blade is more than 10 pairs.Because the leaf of star hair chickweed is to life, so every strain cuttage seeding generally all has two branches.After reaching this standard, after the transplant time of star hair chickweed is being removed Eupatorium adenophorum next year by the end of June～mid-July in, with the root of above-mentioned star hair chickweed seedling slightly with the mode lifting of soil, be transplanted to Ab experimental field in.The method of transplanting is the same with the introducing kind method for planting of star hair chickweed.
3, the direct cuttage technique of star hair chickweed
Ac experimental field in direct cuttage star hair chickweed, to reduce the intermediate link of management.Directly cuttage be chosen in rainwater more during carry out, in order to avoid arid causes survival rate to reduce.Directly cuttage is with 10～25 centimetres line-spacing, and spacing in the rows is as the criterion with the length of internode of star hair chickweed.Concrete grammar is with 1 in the step 2), and by the shade thing of the residual eciophyte of the ecosystem as star hair chickweed.For the ecosystem that does not have other plant after the Eupatorium adenophorum removing substantially, because lacking necessity shades, star hair chickweed cuttage survival rate is lower, between 35%～65%, so should not use direct cuttage technique to carry out the alternative control of star hair chickweed at 35% o'clock if the ecosystem vegetation cover degree after the cleaning is lower than.
Introduce in the technology of planting star hair chickweed at above-mentioned three kinds; star hair chickweed can form suitable protective layer through growing of certain hour after introducing plantation; original eciophyte is taller and bigger usually in the ecosystem; therefore star hair chickweed then can have been contained the invasion once again of Eupatorium adenophorum dry season effectively to they not influences to the intensive covering on the face of land.Directly introduce the star hair chickweed of plantation through 1 (season of growth in the 1 year season of growth, cycle is 1 year) just can reach the purpose that inhibiting violet berba lycopi is invaded, transplant behind the cuttage and seedling culture with directly the needed time of cuttage is 2～3 seasons of growth (2～3 years).
B, C and D type test with the experimental field same introducing of A type plantation star hair chickweed, result of the test unanimity have experimental field been carried out.
Embodiment 3. ecosystem management technology
After transplanting of step 2 culminant star hair chickweed or cuttage, in the time in the 1～February at growth of seedling initial stage, at the more weak characteristics of star hair chickweed primary growth, the density that should keep certain upper strata plant is to guarantee necessary shading, often remove Eupatorium adenophorum again to prevent the too dense harmful effect that star hair chickweed seedling development is caused of Eupatorium adenophorum, when star hair chickweed seedling tendril length reaches 50 centimetres and when beginning branch, can begin to bring into play the advantage of ecological niche of taking up space its dry season, suppress the effect that Eupatorium adenophorum is invaded once again.
In addition, the location that star hair chickweed substitute to be administered is wanted strict all the time and be forbidden and mankind's activity that ecosystem management is irrelevant, particularly herd because the trample of livestock when getting food will to star hair chickweed survive and growth causes harmful effect.The sylvan life grazing animal will firmly be forbidden all the time after substituting improvement enforcement, when star hair chickweed is not brought into play its inhibitory action as yet, except that herding, 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, also all need strictness to forbid.
Alternate test result: in the serial star hair chickweed alternate test such as transplant the directly transplanting of above-mentioned steps, the back of growing seedlings, direct cuttage, herbicide spraying is removed in the above-mentioned ecosystem of Eupatorium adenophorum, by directly transplanting, the back of growing seedlings transplant, direct cuttage star hair chickweed after 1 year, Eupatorium adenophorum seedling incidence is 4～6%, 6～8%, 7～10% (by the proportional meter that accounts for 1 meter * 1 meter investigation sample prescription number respectively, down with), and the Eupatorium adenophorum that does not carry out the contrast sample ground Ad of alternate process is recurred (coming up) rate still up to 75～95%.Management such as herd in conjunction with artificial nursing and strict the taboo, after 1～3 season of growth (year), remove in the ecosystem of Eupatorium adenophorum at herbicide spraying, the incidence equal less than 5% of Eupatorium adenophorum in the alternative above-mentioned ecosystem of administering of above-mentioned star hair chickweed, and the general retarded growth of Eupatorium adenophorum seedling has reached the overall goal that effective control Exotic Harmful Plants is invaded fully.
At experimental field northern 500 meters the close region apart of A type, the Eupatorium adenophorum coverage rate is 2%, does not cause disaster as yet.Select 1600 square metres of introduction and prevention Eupatorium adenophorum invasion tests that are used for star hair chickweed in this zone.In this test, except that there not being Eupatorium adenophorum to remove the treatment step, all the other steps are identical.Find June next year introduce plantation star hair chickweed experimental field in, the coverage rate of star hair chickweed and local other plant reaches 85%～95%, does not see big Eupatorium adenophorum; Do not introducing star hair chickweed experimental field, the coverage rate of Eupatorium adenophorum has reached 8%～12%.
