Description

The Eupatorium adenophorum growth inhibitor

Technical field

The present invention relates to a kind of weed killer herbicide, relate in particular to a kind of Eupatorium adenophorum growth inhibitor.

Background technology

As everyone knows, Eupatorium adenophorum is listed in first of first batch of exotic invasive species by China.Eupatorium adenophorum (Eupatorium adenophorum Spreng), English name crofton weed, pamakani, Chinese another name destroy grass, liberation grass, lose horse grass, black neck grass etc.Composite family (Compositae) Eupatorium (Eupatorium) perennial herb or fruticuli.In originating in, Mexico to Costa Rica one band of South America, 1865 initial is introduced into ground cultivations such as the U.S., Britain, Australia as ornamental plants, now be distributed widely in the global torrid zone, subtropical zone.Mainly be distributed in more than 30 countries and regions such as the U.S., Australia, New Zealand, South Africa, Spain, India, Philippine, Malaysia, Singapore, Indonesia, Papua New Guinea, Thailand, Burma, Vietnam, China, Nepal, Pakistan and Pacific Islands.Eupatorium adenophorum is imported into counties such as the most southern Cang Yuan in the Chinese Lincang Prefecture, Yunnan Province that borders on it, honest and just horse by Burma on the forties in 20th century, back rapid spread, propagation diffusion through over half a century, now in Yunnan of southwest, provinces and regions such as Guizhou, Sichuan, Guangxi, Chongqing, Hubei, Tibet extensively distribute and harm, and, spread eastwards and northwards with southwester still with the speed of about 60km in every year.Wherein Yunnan Province has 93 counties (city) to distribute, and area reaches more than 250 ten thousand hectares.The harm that Eupatorium adenophorum produces herding shows as and occupies the meadow, causes the serious underproduction of herbage.Natural meadow was just lost by the Eupatorium adenophorum invasion and has herded value in 3 years, often caused domestic animal to eat by mistake and was poisoned to death.(seed and pollen can cause asthma to Eupatorium adenophorum to the toxicity of equus; Seed is inhaled into tracheae and lung can cause necrosis and death) and the food refusal of ox by certainly.At present, state, Liangshan Mountain Eupatorium adenophorum hazard area has reached more than 260,000 hectares, and the annual herbage underproduction is more than 500,000,000 kilograms, and domestic animal is dead more than 3000, more than 2,100 ten thousand yuan of economic losses.Behind Eupatorium adenophorum invasion farmland, forest land, the pasture, with crops, herbage and forest contention fertilizer, water, sunlight and space, the growth of other plant around justacrine gram natural disposition material, the inhibition, to crops and economic plants output, meadow safeguard, the renewal of forest has very big influence, is the formidable enemy of agricultural and forestry production.Eupatorium adenophorum is strong to the absorbability of soil nutrient, greatly loss soil fertility.In addition, Eupatorium adenophorum is also comparatively serious to the destruction of soil arability.The Eupatorium adenophorum vitality is strong, wide adaptability, and allelopathy is strong, easily becomes the sociales in the group, even develops into single dominant group.The water extract of Eupatorium adenophorum leaf, root can suppress the sprouting and the growth of seedling of plurality of cereals crop and vegetable seeds.Eupatorium adenophorum is strong to the absorbability of soil nutrient, can greatly consume soil fertility, and is also more serious to the destruction of soil arability.The resistance of Eupatorium adenophorum is extremely strong, and is little to the selectivity of soil, even also can grow in the thin wasteland of arid ridge, unoccupied place, the top of a wall, crack of stone.The countries and regions that have been distributed with Eupatorium adenophorum reported once all that vitality, competitiveness and the ecological plasticity of this grass intrusion farmland, meadow, grassland, roadside, Eupatorium adenophorum were extremely strong, can overwhelm other therophytes rapidly.Its plant can discharge multiple allelochemical, squeezes the other plant growth, and usually large stretch of the generation forms single excellent population, destroys bio-diversity, destroys garden landscape, influences production of forestry.Eupatorium adenophorum to the harm of forestry be occupy deserted mountain suitable for afforestation, influence afforestation, the natural regeneration of tree growth and cutting blank; Invade economic forest land, influence the growth of tea, mulberry, fruit, management intensity is multiplied, and expends great amount of manpower and funds, and serious threat the development of economic crops.The Eupatorium adenophorum plant contains fragrance and pungent chemical substance and some noxious materials that it be unclear that, and its pollen can cause human anaphylactia.Present prophylactico-therapeutic measures is roughly: the one, manually pull out, and in autumn and winter season, manually excavate the Eupatorium adenophorum complete stool, concentrate to dry and burn.The method is applicable to the high farmland of economic worth, orchard and meadow, grassland.When manually pulling out, notice preventing that soil is loosening, in order to avoid cause water and soil loss.The 2nd, biological control, utilize eucalyptus citriodora, hybrid giant napier etc. as an alternative plant suppress the growth of Eupatorium adenophorum.Or utilize the Herba Lycopi trypetid, revolve the growth that skin longicorn and some fungi are effectively controlled Eupatorium adenophorum.Herba Lycopi's Anastrepha diptera, Tephritidae has the characteristic of single-minded parasitic Eupatorium adenophorum, ovum produces on the Eupatorium adenophorum growing point, promptly eats into young tender part after the hatching and gets food, forms insect gall after larva grows up, hinder the growth and breeding of Eupatorium adenophorum, weaken large tracts of land and propagate harm; Revolve the skin longicorn and get food, cause mechanical damage and cause complete stool death in Eupatorium adenophorum collar portion boring; Herba Lycopi's tail spore bacterium, fragrant eupatorium herb alternaric bacteria, fragrant eupatorium herb suede spore bacterium, tikka fungi etc. can cause the Eupatorium adenophorum leaf spot, cause leaf to be infected, chlorosis, growth retardation.The 3rd, chemical control, before the field-crop plantation, every mu of usefulness 41% glyphosate isopropyl amine salt aqua 360-400 gram is converted water 40-60 kilogram, even spraying; Every mu of usefulness of pine forest 70% Sulfometuron Methyl soluble powder 15-30 gram is converted water 40-60 kilogram, even spraying; Barren hill, highway are along the line etc., and every mu of usefulness 24% picloram aqua 200-350 gram is converted water 40-60 kilogram, even spraying; Eupatorium adenophorum in meadow, the orchard prevents and treats with glyphosate, the careful sulfometuronmethyl of using.During chemical control, select sunny weather, notice that droplet does not float on the crop, plug warning sign at applying area simultaneously, avoid causing people, animal to poison or other accidents.These prophylactico-therapeutic measuress or expense height, or toxic and side effect is big, seriously polluted, lack a kind of nontoxic, pollution-free, effective control medicine that cost is low.
