Description
Technical Field
The invention relates to the technical field of submerged plant planting, in particular to a torrent type river submerged plant solid planting device and a solid planting method.
Background
The submerged plant is one of main producers of the water ecological system, has the nitrogen and phosphorus absorption capacity and is also the basis for maintaining the diversity of aquatic organisms, so that the recovery and reconstruction of submerged plant communities and the construction of an underwater forest system are important links for preventing and treating water eutrophication. The root, stem and leaf parts of the submerged plant can respectively absorb the nutritive substances such as nitrogen and phosphorus in the sediment and the water body, and the allelochemicals secreted by the submerged plant have obvious inhibiting effect on algae. The dissolved oxygen concentration can be effectively improved by releasing oxygen through photosynthesis, biological and non-biological suspended substances in the water body can be promoted to precipitate, and the resuspension of sediment sediments in the water body is inhibited, so that the transparency of the water body is effectively improved. In addition, the submerged plant has the function of a biological carrier, the submerged plant can not only provide food for a food chain with complex water body as a primary producer, but also provide survival and spawning habitat for other aquatic animals, and meanwhile, the root, stem and leaf of the submerged plant can be used as a carrier of microorganism, so that a biomembrane is convenient to form, the content of the microorganism in the water environment is increased, and the self-purification capacity of the water body is finally improved, therefore, the growth of the submerged plant is very important for constructing a healthy water ecosystem.
At present, submerged plants are increasingly applied to ecological restoration treatment of riverway water environment, however, in some torrent rivers, because the flow velocity of water flow is high, the seedling roots of the currently common submerged plants for throwing or transplanting seeds are difficult to stably prick roots and are washed away by the water flow, so that the survival rate is low, the survival rate of the submerged plants needs to be improved by repeated planting, and the planting cost is greatly improved. In addition, in some river channels affected by tide, the water level rises and falls rapidly, the instantaneous flow rate is large, and the submerged plants are difficult to root and stabilize by the traditional throwing method. In addition, even if the submerged plant is thrown to make the root prick, the biomass is small at the initial stage of root prick, and the submerged plant is easily prey on herbivorous fishes. Therefore, there is a need to invent a device and a method for fixing and planting submerged plants in torrent type rivers, which can help the submerged plants to take root, prevent prey in the early growth stage and ensure the survival rate.
