Description
Technical field
The invention belongs to ecological protection technical fields, 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
Mangrove (Mangroves) has the function of flood control, wave resistance, storm guard, bank protection, is irreplaceable along seagreen
Barrier；Also there is uniqueness maintaining air carbon and oxygen balance, Cleaning Air and water body environment, greening, beautification, Popular Science Education etc.
Ecology, social and economic benefit, the United Nations's correlative study shows that the annual per hectare of mangrove can generate 3000~9000 dollars
Great number economic value.
But due to utilization unreasonable in recent years and water pollution etc., lead to marine fouling organism Sphaeroma
(Sphaeroma sp.) is largely broken out, and mangrove growth receives severe jamming.Early in 1999, Zheng Dezhang, Liao Baowen et al.
(1999) it finds that Hainan parts Dong Zhaigang mangrove animal Sphaeroma of tarnishing is caused harm, and it is included in the harmful life of mangrove
One of object.Svavarsson etc. (2002) has found, due to being encroached on by Drilling Sphaeroma, dead aerial root is more or aerial root is basic
The mangrove of agensis is easy lodging due to lacking root system support, and this phenomenon most likely occurs in intertidal mudflat lower part water channel
One band of edge.It is current research shows that Sphaeroma is that root system and trunk are not ingested directly to be eaten into as the place inhabited
Root system substance, but the particulate matter in drinking water body, Drilling mangrove pneumathodium and butt are filtered with its front foot, it is formed close
Collect hole, causes full wafer forest withered.If mangrove endangers by Sphaeroma in the protection zones Dong Zhaigang of Hainan, decline in flakes successively
Even dead, decline area reaches 300hm2(the 19% of the stockaded villages Zhan Dong port mangrove), wherein dead area reaches 4hm2More than, decline
Mangrove mainly has Bruguiera conjugata (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
Pneumathodium and backbone portion are lost by moth into spongy intensive hole in Bruguiera conjugata group, and average every plant, up to 618 holes, leads to xylem
It is eaten hollow and the death that lodges completely.
The whole world is less to the research of Sphaeroma at present, and existing research also focuses mostly in Sphaeroma biological characteristics, quick-fried
Reason, harmful characteristics, harm mechanism etc. are sent out, research shows that diffusion blocking, predator pressure, competitive pressure and physiological tolerance
Can influence the distribution of Sphaeroma, in addition the eutrophication indexes such as seawater salinity, water temperature, dissolved oxygen, suspended solid, nitrogen phosphorus with
And these abiotic environments such as flow can also influence the distribution and outburst of Sphaeroma.But how to prevent Sphaeroma at present not
There are significantly more efficient approaches and methods.Existing control method includes mainly source control, physical control, chemical prevention and biology
Prevention etc., but there are certain drawbacks in various methods, not only quickly and effectively but also can be capable of the prevention side of nonpollution environment close friend
Method yet there are no report, specific as follows：
1) source controls：In Hainan, Dong Zhaigang mainly cleans up the duckery in mangrove, closes upstream and periphery and supports
Pig farm, culture pond and dining room etc., control water pollution from source.The measure is effective weight solved and prevent Sphaeroma outburst
Means are wanted, the water pollution in mangrove region can be solved from the root cause, but for having broken out the region of Sphaeroma harm,
It has little effect.
2) physical control：Current existing method includes mainly removing rotten wood, being smeared with lime slurry, and base portion is wrapped up in mud drum
Deng.It is smaller that this method is only useful in tide kinetic energy, the lower mud bank region of tidal height, and needs human cost higher, time-consuming and laborious,
Especially the fetch earth method of package of original place can also cause large effect to primitive environment, and larger threat is constituted to benthon.
Chinese patent application CN 104067889A disclose a kind of physical control for administering the harm of mangrove Sphaeroma with separation principle
Method is carried out plant root isolation processing when ebb tide, is wrapped up plant root at multi-lay winding from bottom to top using film,
Until the aggrieved position top of plant, by top seal after wrapping, using the mud pushed home cleared up originally, by the thin of lower part
Tightly covering seals film, reduces the inlet of the extra large water and air in package region, monthly checks whether the film of package has
Breakage is repaired immediately, and monthly checks Sphaeroma amount in film, can remove film within seven months at the latest.Likewise, this method needs
Want manpower of high cost, it is time-consuming and laborious.
3) chemical prevention：Can effectively kill Sphaeroma drug it is not so difficult on the market look for, but apply in mangrove
It is live then will appear pollution environment while eliminating the serious consequence of other biological, and also have for spraying time and insecticide-applying way
High requirement, one side Sphaeroma are inhabited in channel, drug can effective received letter of acceptance inherently problem, on the other hand,
Frequent flood tide is also the problem for needing to solve to the diluting effect of medicament.
4) biological control：The predator of Sphaeroma includes mainly crab, Bostrichthys sinensis etc., furthermore with its parasite
The possible approaches of Sphaeroma are prevented Deng being, and pollution-free, but this kind of method slowly effect, existing uncertain factor are more, mesh
Preceding achievement in research is also less, it is difficult to generate rapid effect to the outburst of a large amount of Sphaeromas.
To sum up, it is necessary to seek a kind of technology quickly, effectively preventing Sphaeroma.
