The invention also provides a river channel treatment method in the ecological restoration system engineering, which comprises the following steps:
the method comprises the following steps that firstly, the water quality of a river channel is detected by using a water quality detector, the nitrogen and phosphorus contents in the river channel water are mainly measured when the water quality is detected, and the heavy metal contents in the river channel water can be detected; and simultaneously, measuring the water depth of the river channel by using a water depth measuring instrument.
And step two, selecting corresponding submerged plant 5 varieties according to the water quality and the water depth of the river channel and culturing in a submerged plant seedling raising device. The submerged plant 5 can be any one of hydrilla verticillata, eel grass, watermifoil, goldfish algae, potamogeton petiolatus, stonewort and daetzia, and all the submerged plants can absorb nitrogen and phosphorus in the river. When the submerged plant 5 is selected, if the content of cadmium in the river is higher, the golden fish algae or the large arrowhead algae can be planted; if the content of mercury in the river is higher, eel grass or hydrilla verticillata can be planted; if the content of arsenic in the river is higher, the arrowroot algae or hydrilla verticillata can be planted; if the copper content in the river is higher, the watery bladder can be planted with spicate armyworm watery tail algae or Malaysia japonica; if the content of lead in the river is higher, spike-shaped myriophyllum or hydrilla verticillata can be planted; if the chromium content in the river is higher, the golden fish algae or the micro-dentate eyeweed can be planted; if the zinc content in the river is higher, the watercourse can be planted with spike-shaped watercourse or hydrilla verticillata; if the content of cadmium in the river is higher, the watery diet can be planted with spicate armeniaca or potamogeton pectinatus.

Since the submerged plant 5 is planted in the plant planting frame 2 and the root hairs of the submerged plant 5 are distributed in each through hole of the root hair penetrating plate 26, the root of the submerged plant 5 is pulled out from the sludge 4 under the action of the root hair penetrating plate 26 in the pulling-out process of the submerged plant planting device, so that the whole submerged plant 5 can be pulled out with the root hairs. Since the sludge 4 at the bottom of the river channel is soft, the pulling-out process of the submerged plants 5 does not need to consume too much physical strength. When part of the root hairs of the submerged plant is deeply penetrated into the silt 4, the part of the root hairs can be cut off by the wedges on the transverse ribs 261 and the longitudinal ribs 262, so that the submerged plant 5 can be harvested conveniently. In addition, when the benthophyte planting device was taken out in following the river course, 1 trapezoidal (narrow on one's side under being the wide) structural design of base can avoid taking out the animal larva, ovum or the microorganism of river course bottom in the lump, has avoided leading to the fact the destruction to the ecology of river course inside when reaping benthophyte.

The submerged plant is fixed in a mode without matrix, so that the influence of the matrix on the water quality in the river channel is avoided, and the problem of increased bottom mud in the river channel caused by the matrix remaining in the river channel is also avoided. The submerged plant planting device can be fished out from the river channel and can be reused, so that the river channel treatment cost is saved. The invention has the advantages of simple construction mode and less time consumption, can effectively absorb nitrogen, phosphorus and heavy metal contained in the river water body, improves the water quality, improves the transparency of the water body, and simultaneously submerged plants can release oxygen in the growth process to increase the dissolved oxygen in the water body.
