Description
Technical field
The present invention relates to plant species willow catkins flying in the air inhibitor and uses thereof, particularly a kind of willow willow catkins flying in the air pollution inhibitor and the application in control willow willow catkins flying in the air pollute thereof.
Background technology
Willow is the general name of Salicaceae Populus (Populus) plant, and willow is the general name of Salicaceae Salix (Salix) plant, and distributed pole is wide in the world.
China is the centre of origin of willow and willow, and the willow that originates in China has 53 kinds, and willow has 257 kinds, all accounts for half of world willow and willow kind.Annidation is wide because willow and willow have, resistance and vitality is strong, fast growth, breeding easily, plurality of advantages such as tree big, the tree-like grace of height and the area that shades be big, effective, the key seeds of become that urban afforestation, field safeguarding forest are built, turned the four sides green, road and riverbank being afforested.
Since the establishment of the nation, particularly the 60 to 70's a large amount of willows of in the northern city of China, having planted, according to Beijing afforestation census data statistics, only eight districts of the city, Beijing ten thousand strains surplus ten thousand strains surplus the willow 350, the willow 150 of planting.These willows have been brought into play irreplaceable effect to the city trees and shrubs view that improves Chinese northern urban ecological environment and the distinct characteristic of formation.
But because historical reasons, about 50% willow and 80% above willow are female plant in the willow of being planted, these willows and willow many places are in the mature stage at present, annual spring, continue nearly willow catkins flying in the air that danced in the air all over the sky in month and cause serious biological pollution, urban ecological environment construction and city good for habitation's construction are brought certain negative effect to The Surroundings in Cities.
The harm of willow willow catkins flying in the air mainly shows following two aspects:
The first, influence environmental quality, cause certain harm to people are healthy.The willow willow catkins flying in the air that dance in the air all over the sky often fly into pedestrian's eyes, nostril, make people feel very uncomfortable, particularly to those irritated easily crowds, the contact willow catkins flying in the air can cause allergic, symptoms such as little erythema, decortication, redness and itch occur, can stimulate respiratory diseases such as producing asthma, chronic bronchitis when serious; Willow catkins flying in the air are portability and spreading disease germs also, causes nose, eye etc. to locate to produce inflammation.
The second, public safety, traffic safety and communal facility are had certain harm.Willow catkins flying in the air often stop up the radiator fin, and that automobile is easily boiled is flame-out; Willow catkins flying in the air also can block the pedestrian, thereby the vehicle driving sight line influences traffic safety; Willow catkins flying in the air belong to combustible material, and naked lights such as contact cigarette end very easily cause fire to take place; Willow catkins flying in the air also can influence the accuracy of some high precision apparatus measures.A large amount of willow catkins flying in the air that willow produces cause serious biological pollution to urban environment, and urban ecological environment is improved and the construction of city good for habitation brings bigger negative effect.Every year, spring, the willow willow catkins flying in the air all can cause the strong interest of various circles of society period, and citizen administer the pollution problem of willow willow catkins flying in the air as early as possible to adopting an effective measure cry is also more and more higher.Also become simultaneously the difficult problem of puzzlement urban landscaping authorities, make great efforts to inquire into and seek the best solution that the willow willow catkins flying in the air are administered for a long time always.Therefore, press for a kind of easy and simple to handle, suitable large-scale application, and can effectively prevent or reduce the method and the product of the harm of willow willow catkins flying in the air.
Control that China adopts at present and the method that alleviates the willow willow catkins flying in the air mainly contain:
1. eliminate the willow female plant of willow catkins flying in the air, seeds are upgraded in felling, adopt willow staminiferous plant or other trees kind to substitute;
2. remove hat by a willow high position, adopt the willow staminiferous plant to carry out grafting, former willow female plant is become staminiferous plant (of the same race or not of the same race);
3. spray willow female inflorescence thinning agent, cause the inflorescence formation phase to come off, remove the female fringe of willow.But all there is very big technical limitation in these three kinds of methods in application at present, have limited the large scale application of three kinds of methods.
The limitation of above-mentioned three kinds of technology mainly shows:
First method: because of willow female plant quantity existing in the city very big, and the mature stage and the ecological benefits that are in plant growing are brought into play the most remarkable period, all felling is eliminated these willow female plants and can greatly be destroyed original ecotope in city and greenery patches view, trees after the replacing are difficult to form the greening of original trees and the effect of shading in a short time, thereby bring the loss that to estimate for the urban afforestation cause, the serious ecological benefits that reduce urban afforestation, add these willow female plants of replacing and need drop into huge manpower and financial resources, make that interior all superseded willow female plants of short time are also unrealistic.
Second method: willow high position grafting technology need be cut down the tree crown of original female plant willow, and on its major branch the tender male branch of grafting children, become female tree and be Xiong Shu, need possess the grafting professional operation of higher technical merit, have certain production safety hidden danger simultaneously.Greening and the landscape effect of this method initial stage to trees destroys bigger, need behind the willow high position grafting after 3～4 years, could recover original greening and landscape effect, the grafting later stage needs higher maintenance cost simultaneously, needs constantly to remove the sprout tillers of former willow female plant, and prunes again and recover the tree type.The landscape effect of higher grafting cost and willow high position grafting meeting heavy damage willow makes it lose tall and big tall and straight tree performance, and the high position grafting technology can't be applied to willow, has greatly limited applying of high position grafting technology.
The third method: willow female inflorescence thinning agent can make the willow female inflorescence form absciss layer in advance at base portion, female inflorescence is not being come off before the willow catkins flying in the air ahead of time, but this medicament only is about 70% to the effect that removes of willow female inflorescence, and require tighter to spraying time and pesticide application technology, need when willow female inflorescence length to 4～6cm dispenser just can reach and remove effect preferably, dispenser too early can reduce control efficiency greatly, and dispenser is crossed and lately can be caused serious poisoning again, influences the normal growth of willow; This medicament can produce poisoning to other broad leaved plant (comprising ground cover plant, shrub etc.) early that germinates under willow and the willow simultaneously, and the negative effect of medicament is very outstanding.Medicament can form serious drift in spray process, air ambient is formed secondary pollution.The higher control cost and the limitation of above-mentioned technology have greatly limited the large scale application of this medicament.
Because of there is bigger technical limitation in above-mentioned three kinds of methods, causing can't large-scale promotion application in the practice.
