Background technology
Weeds have been long wrong the time, long wrong seasonal plant.Mikania micrantha (formal name used at school: Mikania micrantha), be called again Mikania micrantha or Mikania micrantha, originate in South America, be annual vine unique among the composite family (Du Shiya, the shape plant is climbed up by holding on in Hong Kong, Urban Council's publication, 1986: 95 pages); Because the Mikania micrantha growth rate is very fast; capture the nutrient of other plant; so cause other plant to be difficult to the title that existence has " green killer "; also classified as Invasive Alien Species (the Liang Haiju work of the 100 kinds of tool harm power in the whole world by World Conservation Union; Hong Kong nature illustrated handbook series 4 common shrub plants, open-air trend, 35 pages; ISBN 988-98539-4-9), be a kind of quarantine weeds.
Mikania micrantha is perennial herbaceous stem or woody climber, stem is elongated, crawl or climb, multi-branched, by pubescence or near without hair, green during the children, closely cylindrical, old stem is filbert, many rib lines of tool.Stem middle leaf triangular shape is avette to avette, long 4.0～13.0cm, and wide 2.0～9.0cm, base portion is heart-shaped, the nearly halberd shape of idol, tip is point gradually, several bastards of edge tool or shallow wavy crenature, the two sides is without hair, and base goes out 3～7 arteries and veins; Long 2.0～the 8.0cm of petiole; The Ye Jianxiao on top, petiole are also short, and capitulum is most, often lines up the compound corymb shape at the branch end, inflorescence is gradually very thin, and the capitulum at top is spent open first, and is open gradually downwards successively, long 4.5～the 6.0mm of capitulum contains 4 of Xiao Hua, is solid hermaphrodite flower entirely, 4 pieces of phyllarys, long and narrow ellipse, the top is point gradually, the anxious point of part, green, long 2～4.5mm, the involucre base portion has the oval-shaped little bract of a wire (outer bract), long 1～2mm, and flower has fragrance; Corolla white, carinate, long 3～3.5 (4) mm, eaves section mitriform, 5 fissures, the long 1.5～2.0mm of achene, black, by hair, tool 5 ribs, by body of gland, pappus has 32～38 (40) bar seta to form, white, long 2～3.5 (4) mm.Mikania micrantha and have vegetative propagation and produce all strong characteristic of seed bearing sexual propagation ability, each joint of its viticula is except growing the sprouting, can both grow adventive root between joint and the joint, can give birth in one day to increase and reach 24 centimetres, the individual plant Mikania micrantha can cover about 25 square metres of area plants within several months, the title of " one minute one mile (Mile-a-minute weed) " is arranged, and this is its main cause that is difficult to thoroughly root out.Its seed coin black, 1,000 only nearly weighs 1 g, and there is pappus on the top, can be with the wind and overwater propagation, every square metre can be produced about 170,000 seeds.
Mikania micrantha has phototropism, climbs up trees and will twine the complete stool plant, and it is deadly that host plant photosynthesis is damaged, the multifarious serious infringement of primary ecology system biological.In China, Mikania micrantha main harm Natural Secondary Forests, forest plantation, to the nearly all seeds below local 6～8m, especially serious to some less forest harm.Endanger serious arbor species mangrove, blood paulownia, crape myrtle, five-leaved chasts tree, Ficus microcarpa are arranged; Shrub species has lantana, common embelia fruit, spends common embelia fruit in vain, leaf of plum Chinese ilex, Chinese sumac, Common Leafflower Herb, Herba Excoecariae cochinchinensis etc.; Shrub plant has hill gooseberry, four seasons mandarin orange, Huashan alum, Rose Mallow Root, dog bud flower etc.; Arbor species have longan, sapodilla tree, Chinese juniper, China tree, guava, Piao Shu, lichee Mikania micrantha, kamuning, ilexrotunda, yellow camphor tree, camphor tree, Chinese tallow tree.
