Description
Technical field
The invention belongs to technical field of pesticide preparations, be specially medicament of a kind of quick control malignant aquatic weed and algae and uses thereof.
Background technology
" wawter bloom " (water blooms) is a kind of natural, ecological phenomenon in the fresh water, caused by algae such as blue-green algae, green alga, diatoms." wawter bloom " phenomenon is just on the books on Ancient Times in China history, and when " wawter bloom " took place, it is blue or green that water generally is, and in their very fast disappearances of occurring in nature, do not bring harm to aquatic products animal and human class.After the eutrophication, " wawter bloom " is frequent to be occurred in the fresh water, and area spreads year by year, and the duration prolongs year by year.Taihu Lake, Dian Chi, Chaohu, Hongchehu Lake have " wawter bloom ", even the river that flows, as maximum tributary, the Changjiang river---" wawter bloom " also appears in the section of river, Hankow, downstream, Han River.The maximum harm that " wawter bloom " causes in the fresh water is: the drinking water source is on the hazard, the algae toxin influences human beings'health by food chain, the secondary metabolite MCRST of blue-green algae " wawter bloom " can damage liver, has short cancer effect, directly threatens human beings'health and existence.In addition, the filter of waterworks is by algae " wawter bloom " filling, and " wawter bloom " that swim on the water surface influences view, and unpleasant stink is arranged.When the algae raised growth, these algae can discharge toxin---water bloom, and fish are had toxic action.After the algae mortality, in corrupt, the process that is decomposed, also want dissolved oxygens a large amount of in the consume water, make the serious stench of water body.The main cause that causes the wawter bloom phenomenon still is that the waters is used chemical fertilizer, resident living sewage and industrial wastewater along the line in a large number and entered rivers and lakes in a large number, causes nitrogen in the rivers and lakes, phosphorus, potassium equal size to rise.The freshwater resources of China are just very shortage originally, and the algal tufa of wreaking havoc (wawter bloom) breaks out, and this shortage phenomenon is made the matter worse.How controlling breaking out of algal tufa effectively, allow people enjoy safe freshwater resources and healthy ecotope, is great demand both domestic and external.
In addition, in recent years along with the malignant aquatic weed ecological invasion, in many developing countries, the calamity of malignant aquatic weed has been not only an ecological problem, and becomes serious economic problems.Some countries in Africa and South Asia, the course line that blocks up after weter hyacinth breaks out, obstruction water channel, threat fishery even invasion power station or the like directly cause serious economic loss.In China, only salvage one every year and just spend more than one hundred million units, yet this still can not stop spreading of weter hyacinth and loss that it causes.The ethologist is verified, the invasion of weter hyacinth causes omnibearing, three-dimensional destruction will for the aquatic ecosystem: on the water surface, the layer upon layer of plant of weter hyacinth can exceed the water surface more than 1.5 meters, their block sunlight enter water body, oxygen in a large amount of consume water causes illumination under water and oxygen to lack; And under the water surface, when the rotten plant of dead back enrichment pollutant sinks under water, simultaneously a large amount of pollutants are brought into the bottom, make the end give birth to the ecosystem and suffer extinction.
In the bitter Shanghai that enjoys the weter hyacinth invasion, the numeral of appearance of the city environmental sanitation administrative department shows, ton weter hyacinth surplus Shanghai City had salvaged 260,000 altogether in 2006, cost be set out 3889 person-times and 1092 ship/time ship.Yet everything can not stop in July, 2007 weter hyacinth to stage a comeback former years in advance.Machinery is salvaged and is seemed simple and fast, is but generally acknowledged it is the most expensive improvement method.In Shanghai, about 100 yuans of the cost of one ton of weter hyacinth of every salvaging does not also count shipping charges and landfill expense here, and of paramount importancely is, the speed that machinery is salvaged is unable to catch up with the speed of weter hyacinth growth at all.Every year all will be manually salvaged weter hyacinth on ground such as China Guangdong, Yunnan, Zhejiang, Fujian, and only Wenzhou, Zhejiang and Putian, Fujian artificial salvage expenses in 1999 just is respectively 1,000 ten thousand and 5,000,000 yuan.How many artificial weter hyacinth total costs of salvaging in the whole nation has, and present do not have accurately statistics, but surpass 100,000,000 yuan at least, but also must persevere year after year.
Because the weter hyacinth overgrowing, the Dian Chi has become smelly pool, and the desirable water tourism circuit that builds up the 1970s and 1980s is forced to cancellation; Dian Chi Cao Hai also has 16 kinds of higher plants the sixties, and to only remaining 3 kinds of the nineties in 20th century, the edible seaweed flower waits because of living space forfeiture death; In some areas, weter hyacinth even " involving " social security also, dense plant in blocks provides the natural field of concealing for criminal.Weter hyacinth is not only wreaked havoc China, is also endangering many countries in North America, Asia, Oceania and Africa, allows world's headache for it, becomes the typical case's " representative " for the war of people and biology.The numeral of World Conservation Union shows that in the poorest Africa, the world, seven annual " costs " of paying for the control weter hyacinth of country are 20,000,000 to 50,000,000 dollars.And the effect of weter hyacinth? because the fast development of feed industry since the eighties in 20th century, by basic " discard ", other purposes arouse doubts laden with anxiety especially, are difficult to conviction as the main application of feed for it.The insider points out no matter still calculate from social perspective from economical, ecological, loses more than gain.
