Method for governing invasive species flower rice grass using a technique integrated by mow and regulation of level

Abstract

The invention relates to a control method of spartina alterniflora, belonging to the technical field of ecological engineering. Spartina alterniflora is artificially introduced in China in the 1980s, and plays a positive role for damping waves, protecting slopes, promoting deposition and reclaiming lands on Chinese coastline, however, as an alien invasive species recognized internationally, the population characters of powerful breeding and rapid extending ability of the spartina alterniflora bring a series of negative effects to the natural wetlands ecosystem of Chinese coastal tidal land and the regional biodiversity; and control of the spartina alterniflora is already a universal problem. The prior single physical, biological or chemical control method has the disadvantages of low efficiency, high environmental pollution risk, low ecological safety, high cost and unobvious control effect. The invention overcomes the disadvantages of the prior preventing and controlling techniques, and utilizes the comprehensive control method of cradling and water level regulating, eradicates the invasive species and controls the growth and rapid extension of the invasive species through restraining the growth of spartina alterniflora, plays an active restoring role to the ecological system destroyed in large areas, and provides an efficient path for preventing spartina alterniflora from spreading extensively in coastal areas.

Description

technical field [0001] The invention relates to a method for controlling the invasive species of Spartina alterniflora by integrated technology of mowing and water level regulation, which belongs to the technical field of ecological engineering Background technique [0002] Spartina aterniflora (Spartina aterniflora) is a perennial herb belonging to Poaceae and Spartina. It is native to the Atlantic coast of the United States and is a perennial salt marsh plant growing in the intertidal zone. The plants of Spartina alterniflora are thick and tall, with dense growth, and the ground height can generally reach 1.0-2.0m. It has strong and rapid reproductive expansion ability. Spartina alterniflora has a well-developed root system, which can penetrate into the soil up to 1.5m. It has strong functions of resisting wind and waves, protecting beaches and banks, and promoting siltation and land formation. In 1979, Spartina alterniflora was introduced into th...

Problems solved by technology

This method has the following advantages: it is not as time-consuming, laborious and inefficient as a single physical or mechanical method; it is not as easy to cause environmental pollution as chemical control; it does not introduce alien animal natural enemies or pathogenic microorganisms like biological control, There is the possibility of secondary biological invasion and a greater risk of ecological security; there is no problem of alien species crowding out local species
