Description

A kind of ecological effective technology making mutual spartina natural death

Technical field

The present invention relates to eco-environment technology field, specifically a kind of ecological effective technology for making mutual spartina natural death.

Background technology

Mutual spartina is that Alien Invasive Plants the most serious are endangered in China's Coastal hazards, is subordinate to grass family, spartina belongs to life The perennial herb in intertidal zone.Plant salt tolerant is resistance to be flooded, and wind and wave resistance, seed can be with wind wave propagation.Root Distribution is as deep as 60cm's In the soil of beach, single plant can breed dozens or even hundreds of strain in 1 year.The under ground portion of Spartina alterniflora includes subterranean stem and fibrous root, factually Ground is observed, and the more cross direction profiles of subterranean stem, Root Distribution depth is up to 1~2m.The extension of Spartina alterniflora includes walking vines to prolong and plant Son is propagated.

Due to Spartina alterniflora's stalk it is intensive it is sturdy, underground rhizome is flourishing, rapid subsidence and the siltation of silt can be promoted, because This, early 20th century, many countries were successively introduced to protect beach bank protection, created land with silt.Although Spartina alterniflora is in coastal ecology There are certain ecological functions in system, but its superpower reproductive capacity in tidal beach wetland habitat makes Spartina alterniflora spread unchecked, sternly Neritic organism habitat is destroyed again, influences mudflat aquaculture and exchange of seawater ability, threatens native country Coastal Ecosystem.In order to It repairs and is damaged Wetland Function, protect Studies on Avian Habitat and migrate channel ecological safety.Research invention one kind is eliminated mutual from ecology Spartina is act in a hurry.

Distribution in China present situation：Spartina alterniflora be distributed widely in Fujian, Zhejiang, Shanghai, Jiangsu, Shandong, Tianjin and The area of the coastal area of the provinces such as Liaoning, especially jiangsu coast, Spartina alterniflora has reached 125km², form national area Maximum Spartina alterniflora's manpower salt marsh.Local government spares no high price to utilize a large amount of people to control the unordered extension of mutual spartina Power, material resources use artificial or machine according to the different developmental phases of Spartina alterniflora's history of life, the size of distribution area and area position difference The measure of tool eradicate and using the fiber cloth of impermeable light or the material of other shadings to the distributed areas of Spartina alterniflora into Row covers；Pool water storage is enclosed according to landform construction and carries out long-term water logging or the influence of control tidewater in anaerobic ring in many coastal areas Mutual spartina indeterminate growth is not allowed under border or no tidal action.The also useful method uprooted, removal or the Small Population for killing new life, The root for crushing tool power of regeneration is deep-cut with big machinery to the small patch that ripe population edge-diffusion is formed, then by the rhizome of crushing Segment buries soil surface hereinafter, it is allowed to rot, but still has power of regeneration by the mutual spartina of the propagation of seed, has place dynamic With a large amount of manpowers in mutual spartina productive phase, immature kind of fringe is cut, the propagation of seed is limited, also many coastal areas are logical It crosses Chemical Control and carries out weeding using herbicide, earliest for controlling weeds in field, be currently used for the weeding of control Spartina alterniflora Agent includes glyphosate and imazapyr, the former can rapidly be absorbed by plant, and as assimilation products is conducted to entire plant, fragrance The biosynthesis of race's amino acid is blocked, and is influenced plant cell division and Chlorophyll synthesis, is hindered protein metabolism process, causes Plant is dead；The latter is by preventing the synthesis of branched-chain amino acid from realizing control plant growth.Can the use of pesticide but seriously break It is broken coastal marine ecosystem environment.Seawater is polluted by pesticide.

Up to the present, the method either physics of the above mutual spartina of elimination, biology, manually, pesticide All mutual spartina cannot might as well be made to die absolutely, and these types of method is expensive laborious, as a result prove all to be in use failure, mutual rice Grass or equally Coastal beach grow.
