Shallow sea grass bed restoration method

Abstract

The invention discloses a shallow sea grass bed restoration method. Traditional sea grass bed recovery methods include a habitat restoration method, a seed method and a rhizome transplanting method. The methods have shortages of long cycle and low survival rate. The shallow sea grass bed restoration method includes the measures of locating a restoration site, cleaning and tidying the restoration site, pretreating the restoration site, distributing protective nets on the restoration site, selecting a grass source land, selecting types of sea grass, selecting restoration time, collecting grass,planting sea grass, maintenance management, monitoring and the like. By the method, restoration survival rate of shallow sea grass reaches 85%, and the restoration cycle is 90-180 days. Therefore, the method is effective in restoring shallow sea grass, and has high level of restoration speed and breadth of shallow sea grass.

Description

technical field [0001] The invention relates to a method for restoring shallow sea seagrass beds, and belongs to the technical field of marine plant production. Background technique [0002] Seagrass beds in shallow seas are feeding grounds, habitats, nursery grounds or shelters for many precious marine organisms such as dugongs, green turtles, and seahorses. The functional value of ecological services is comparable to that of typical marine ecosystems such as coral reefs and mangroves. In addition, seagrass beds also play an important ecological role in promoting silt consolidation, improving nearshore water quality, and maintaining the balance of the global carbon cycle. However, this ecosystem is one of the most fragile on Earth, with 18% of the globally recorded seagrass covering an area of ​​approximately 33,000 km2 lost due to direct or indirect human impact in the past two decades. loss, and the rate of global seagrass decline is accelerating! The accelerated degra...

Problems solved by technology

Although the seed method has little negative impact on the grasslands, the germination rate of seagrass seeds generally does not exceed 10%, and seagrass seeds are not easy to collect and are easily lost after sowing. rarely used

The advantage of the rhizome transplant method is that the damage to the grass source is less, but it is difficult to fix when planting, so the survival rate is generally low
