Hydraulic power spread wetland plant seed capturing device and method

Abstract

The invention provides a 'hydraulic power spread wetland plant seed capturing device and method', and belongs to the technical field of ecological engineering. The capturing device is characterized bycomprising a buoyancy base and at least one conical net cover; the conical net cover is a conical structure of which the bottom surface is open, and a plurality of meshes are distributed in a conicalsurface of the conical net cover; a structure which can allow water and a plant seed to penetrate in but can stop the plant seed from penetrating out is arranged on each mesh; the bottom surface of the conical net cover is connected with the top surface of the buoyancy base; the capturing device can be fixed at a certain position in water through a fixing component; and buoyance F provided by thebuoyance base meets the following conditions: device G-0.8* water rho g device V</= buoyance F</= device G-0.4* water rho g device V; the device G means the weight of the capturing device, water rhomeans water density, g is a gravity coefficient, and device V means the volume of the capturing device. Compared with an existing device, the device and method have the advantages that the number of the captured seeds is greater by multiple times.

Description

technical field [0001] The invention relates to the technical field of ecological engineering, in particular to a seed capturing device and method for wetland plants. Background technique [0002] Wetland plants generally refer to plants that grow in wetland environments. Wetland plants in a broad sense refer to plants that grow in swamps, wetlands, peatlands, or waters that are less than six meters deep at low tide; wetland plants in a narrow sense are Refers to plants that grow at the junction of water and land, where the soil is wet or there is shallow water. In addition to directly providing humans with industrial raw materials, food, ornamental flowers, medicinal materials, etc., wetland plants also play a key role in the wetland ecosystem. [0003] Hydropropagation is one of the most important dispersal pathways for wetland plants, and it has important ecological significance for wetland plant reproduction and wetland restoration. At present, the water-seeded seeds o...

Problems solved by technology

[0007] Although the above-mentioned existing device considers the fluctuation of water level, a multi-layer net cover is set, which is relatively effective for seed harvesting in the process of water level drop, but when the water level rises, the seeds harvested by the low-level net cover are easily washed away by water; Soaking is easy to damage; the contact surface or collection port is too small, it is not easy to collect seeds; the harvested seeds cannot be distinguished, and it cannot meet the simple and efficient universal requirements for harvesting water propagating plant seeds
