Eelgrass donor plant collection and transplanting method

Abstract

The invention discloses an eelgrass donor plant collection and transplanting method. The eelgrass donor plant collection and transplanting method includes the steps that a collection area is selected,and the area of collection quadrats, the composition number of transplanting units and the transplanting density of the transplanting units are determined; a sea grass bed internal area where eelgrass grows vigorously is selected as the collection area; the area of the collection quadrats is the 20*20 cm<2>-60*60 cm<2>, and interval of the collection quadrats is 0.5-1 m; the composition number ofthe transplanting units is 1 strain / PU-3 strain / PU; the transplanting density is 6 PU / m<2>-12 PU / m<2>. By adopting the eelgrass donor plant collection and transplanting method, not only can it be ensured that collection of eelgrass donor plants cannot cause any bad influence on natural sea grass beds, but also the application amount of the eelgrass donor plants is significantly reduced, and the problems can be solved that by adopting current eelgrass donor plant collection and transplanting methods, the natural sea beds are greatly damaged, and the supply of the eelgrass donor plants is insufficient.

Description

technical field [0001] The invention relates to the technical field of marine resource restoration, in particular to a method for collecting and transplanting eelgrass donor plants. Background technique [0002] Seagrass is the only type of angiosperm on the earth that can live completely in seawater. The seagrass bed constructed is one of the three typical coastal ecosystems and has extremely important ecological functions. It can not only provide food for many marine organisms and a variety of Habitat also plays a vital role in capturing sediment, stabilizing sediment, preventing wind and embankment, purifying water, cycling nutrients, and sequestering carbon, and is often used as a biological indicator of water quality and ecosystem health. [0003] However, almost all seagrass beds worldwide are in constant decline due to changes in the natural environment and human activities. Seagrass plant transplantation is considered to be the most effective method to reduce and co...

AI Technical Summary

Problems solved by technology

[0006] In view of this, the present invention provides a method for collecting and transplanting eelgrass donor plants, which can not only ensure that the collection of eelgrass donor plants will not cause any adverse effects on the natural seabed, but also can significantly reduce the amount of eelgrass donor plants. The amount of donor plants used can overcome the problems of large damage to the natural seabed and insufficient supply of eelgrass donor plants in the existing methods of collecting and transplanting eelgrass donor plants
