Technical field
The invention belongs to ecological protection technical field, and in particular to a kind of dual medicament of prevention and control Sphaeroma and apply the medicine
The method of agent prevention and control Sphaeroma.
Background technology
Rhizophora apiculata Blume (Mangroves) with flood control, wave resistance, storm guard, bank protection function, be irreplaceable along seagreen
Barrier；Air carbon and oxygen balance, Cleaning Air and water body environment is being maintained, the aspect such as greening, beautification, Popular Science Education also has uniqueness
Ecology, Social and economic benef@, the United Nations's correlational study shows, the annual per hectare of Rhizophora apiculata Blume can produce 3000～9000 dollars
Great number economic worth.
But due to irrational exploitation in recent years and the reasons such as water pollution, cause marine fouling organism Sphaeroma
(Sphaeroma sp.) breaks out in a large number, and Rhizophora apiculata Blume growth receives severe jamming.Early in 1999, Zheng Dezhang, Liao Baowen et al.
(1999) find that Hainan Dong Zhaigang part Rhizophora apiculata Blume animal Sphaeroma of tarnishing is caused harm, and it is listed in the harmful life of Rhizophora apiculata Blume
One of thing.Svavarsson etc. (2002) has found, due to being encroached on by Drilling Sphaeroma, dead aerial root is many or aerial root is basic
Obsolete Rhizophora apiculata Blume is easily lodged due to lacking root system support, and this phenomenon most likely occurs in intertidal mudflat bottom water channel
Edge one is carried.Current research shows that Sphaeroma is as the place that perches root system and trunk, does not directly ingest and is eaten into
Root system material, but with the particulate matter in its front foot filter drinking water body, its Drilling Rhizophora apiculata Blume pneumathodium and butt, formed close
Collection hole, causes full wafer forest to wither.Such as in the Dong Zhaigang protection zone of Hainan, Rhizophora apiculata Blume is subjected to Sphaeroma and endangers, and fails in flakes successively
Even dead, decline area reaches 300hm2(the 19% of Zhan Dong stockaded village port Rhizophora apiculata Blume), wherein dead area reach 4hm2More than, decline
Mangrove mainly has Bruguiera gymnoihiza (L.) Savigny. (Bruguiera gymnorrhiza), autumn eggplant (Kandelia candel), Avicennia marina
(Avicenniamarina) and extra large Mulberry (Sonneratia caseolaris) etc., wherein most heavy with Rhizophoraceae hazard of plant, such as
In Bruguiera gymnoihiza (L.) Savigny. group, pneumathodium and backbone portion are eaten into and are lost into spongy intensive hole, and averagely per plant, up to 618 holes, causes xylem
Eaten hollow and the death that lodges completely.
At present the whole world is less to the research of Sphaeroma, and existing research is also focused mostly in Sphaeroma biological characteristicses, quick-fried
The aspect such as reason, harmful characteristics, harm mechanism is sent out, research shows diffusion blocking, predator pressure, competitive pressure and physiological tolerance
The distribution of Sphaeroma can be affected, in addition the eutrophication indexes such as seawater salinity, water temperature, dissolved oxygen, suspended solid, nitrogen phosphorus with
And these abiotic environments such as current can also affect distribution and the outburst of Sphaeroma.But how to prevent and treat Sphaeroma up till now not
There are significantly more efficient approaches and methods.Existing prevention and controls mainly include Sources controlling, physical control, chemical prevention and biology
Preventing and treating etc., but the drawbacks of various methods all have certain, not only quickly effectively can be capable of the friendly preventing and treating side of nonpollution environment again

Means are wanted, can solve the water pollution in Rhizophora apiculata Blume region from root, but for having broken out the region of Sphaeroma harm,
Have little effect.
2) physical control：Existing method mainly includes to remove rotten wood, is smeared with lime slurry at present, and base portion mud drum is wrapped up in
Deng.This method is only useful in that tide kinetic energy is less, the relatively low mud bank region of tidal height, and needs human cost higher, wastes time and energy,
Especially the fetch earth method of parcel of original place can also cause large effect to primitive environment, constitute larger threat to benthon.
Chinese patent application CN 104067889A discloses the physical control that a kind of utilization separation principle administers the harm of Rhizophora apiculata Blume Sphaeroma
Method, which carries out plant root isolation processing when ebb tide, becomes multi-lay winding to wrap up from bottom to top plant root using thin film,
Until the aggrieved position top of plant, by top seal after wrapping, using the mud pushed home of original cleaning, by the thin of bottom
Film is tightly covered and is sealed, and is reduced the inlet of the extra large water and air in parcel region, is monthly checked whether the thin film of parcel has
Breakage, is repaired immediately, and monthly checks Sphaeroma amount in thin film, can remove thin film within seven months at the latest.Likewise, the method is needed
Manpower high cost is wanted, is wasted time and energy.
3) chemical prevention：Effectively can kill Sphaeroma medicine commercially not so difficult look for, but apply in Rhizophora apiculata Blume
Live then pollution environment occurs while eliminating the serious consequence of other biological, and spraying time and insecticide-applying way are also had
High requirement, one side Sphaeroma is perched in channel, medicine can an effective received letter of acceptance inherently difficult problem, on the other hand,
Frequently flood tide is also to need the difficult problem for solving to the diluting effect of medicament.
4) Biological control：The Predator of Sphaeroma mainly includes Eriocheir sinensiss, Bostrichthys sinensis etc., furthermore with its parasite
Deng being all the possible approaches of preventing and treating Sphaeroma and pollution-free, but this kind of method slowly effect, the uncertain factor that exists are many, mesh
Front achievement in research is also less, it is difficult to produce rapid effect to the outburst of a large amount of Sphaeromas.
