A target based tidal flat wetland restoration method comprises: (1) determining a target, (2) constructing an ecological unit by microtopography transformation on the tidal flat wetland required to be restored, (3) applying biochar material and salt-resistant ecological material within the ecological unit, (4) performing waterfront plant configuration within the ecological unit. The restoration method uses the natural tidal ebb and flow to adjust water and salt conditions in the ecological unit (salt content is reduced by more than 80%) and maintaining the target water level (0-2 m), optimized the structure of soil microbial community (the abundance of soil bacteria has been increased by more than 200%), improved the germination rate and survival rate of plants during tidal flat restoration process (the germination rate has reached more than 90%, and the survival rate has been increased to more than 62%), enriched plant species in waterfront zone (≥12 species).

A plant seed harvesting device comprises a multi-layer net unit; the multi-layer net unit comprises collecting net, intermediate layer net and bottom layer net; the collecting net, the intermediate layer net and the bottom layer net are all plate-like structure having a plurality of meshes; the peripheral edge of the plate-like structure is a net frame, area with the meshes is net face; The collecting net, the intermediate layer net and the bottom layer net are arranged closely in the axial direction to form the multi-layer net unit; mesh sizes on the collecting net, the intermediate layer net and the bottom layer net are configured to be successively and gradually decreased; plant seeds can pass through the meshes of the collecting net; air but not plant seeds can pass through the meshes of the bottom layer net.
