River channel planting device and method for submerged plants

Abstract

The invention discloses a river channel planting device and method for submerged plants. A culture device comprises a supporting frame and a culture body, the supporting frame comprises a bottom plate, and two ends of the bottom plate are separately connected with a left support and a right support; the culture body comprises a breeding layer and a nutrient supply layer, and the breeding layer comprises a first sponge layer, a second sponge layer and a circle of grille fence; a lifting device comprises a left mounting seat and a right mounting seat, the left mounting seat is provided with a first screw rod, and the second mounting seat is provided with a second screw rod; the lifting device is further provided with limit pins; the lower ends of the left and right mounting seats are separately provided with one fixing pin; and a PLC, cameras and light sensors are also arranged. According to the river channel planting device and method for the submerged plants provided by the invention,the lifting device and the culture device are arranged, the lifting device can automatically adjust a depth of the culture device in a river channel according to growth conditions of the submerged plants, so that the submerged plants can better grow, the culture device can even be lowered to the bottom of a river bed finally, and therefore submerged plant ecology in the river channel gradually recovers.

Description

technical field [0001] The invention relates to the technical field of planting submerged plants in urban rivers, in particular to a device and method for planting submerged plants in rivers. Background technique [0002] In urban rivers, there are two main reasons why submerged plants cannot survive. One is that the two sides of urban rivers are generally vertical stone revetments, not slow-falling revetments, and the water depth is relatively deep. photosynthesis. The second is that even if the river water is relatively shallow, most of the urban river bottoms are hard bottom or construction waste, etc., and submerged plants cannot attach to it. At present, some landscape units try to plant submerged plants with soil attached to the geotextiles, but due to the smooth surface of the geotextiles, the soil is easy to diverge and lose, and the submerged plants cannot complete normal growth. Moreover, the ammonia nitrogen in some urban rivers is relatively high, greater than ...

Problems solved by technology

[0002] In urban rivers, there are two main reasons why submerged plants cannot survive. One is that the two sides of urban rivers are generally vertical stone revetments, not slow-falling revetments, and the water depth is relatively deep. photosynthesis

Second, even if the river water is relatively shallow, most of the urban river bottom is hard bottom or construction waste, etc., and submerged plants cannot attach to it.

At present, some landscape units try to plant submerged plants with soil attached to the geotextile, but due to the smooth surface of the geotextile, the soil is easy to diverge and lose, and the submerged plants cannot complete normal growth.

In addition, the ammonia nitrogen in some urban rivers is relatively high, greater than 4-5mg / l, which will cause the rot and death of submerged plants
