Method and device for assisting retention, germination and seedling planting of plant seeds and/or propagules in coastal wetland habitat

Abstract

The invention discloses a method for assisting retention, germination and seedling planting of plant seeds and / or propagules in a coastal wetland habitat. The method comprises the following steps: (1)making a scheme for assisting retention, germination and planting of coastal wetland plant seeds and / or propagules according to coastal wetland habitat characteristics and target plant species; and (2) according to the water quantity, the flow speed, the sweep range and the habitat matrix physical and chemical properties and gradient of the water flow which frequently moves in one direction or ina reciprocating manner; and designing a totally-enclosed or semi-enclosed stagnant water tank for retarding water flow and preventing the seeds and / or propagules and / or seedlings from being washed away by the water flow according to the seed retention time or matrix stabilization time required for germination of the seeds and / or propagules of the target plants and / or field planting of the seedlings. According to the method, the problem that target plant seeds or young plants distributed in the coastal wetland are frequently submerged by water flow carrying positions or flushed into water dueto frequent one-way or reciprocating water flow movement existing in the coastal wetland can be effectively prevented. The invention also discloses a water retention tank for assisting the retention,germination and seedling planting of plant seeds and / or propagules in the coastal wetland habitat.

Description

technical field [0001] The invention belongs to the field of ecology, and relates to a method and a device for assisting the retention, germination and seedling colonization of plant seeds and / or propagules in coastal wetland habitats. Background technique [0002] In the coastal wetland habitat, due to the frequent unidirectional or reciprocating water movement, there are often problems in the retention, germination and seedling colonization of seeds and / or propagules of plants (especially target plants) distributed therein (such as Seeds and / or propagules and young plants are often transported by water currents or directly washed into water bodies and submerged), therefore, it is not conducive to the successful establishment of wetland plant populations or communities in such habitats and the normal performance of their ecological functions. Today, as the protection of coastal wetlands in my country is receiving more and more attention, it is extremely necessary to develop...
