Technical Field
The invention relates to the technical field of improving, beautifying and treating water body environment by using aquatic plants and restoring aquatic vegetation by using eutrophic algae-type lakes or water bodies, in particular to a submerged turf planting method for improving the ecology of hard riverways and pond ponds.
Background
The recovery of aquatic vegetation, particularly submerged vegetation, becomes the key for the eutrophication treatment of water bodies such as lakes in China, and in the actual engineering of aquatic vegetation recovery, a large number of aquatic plants are almost completely collected in natural lake water bodies and planted in the area needing to recover the aquatic vegetation by utilizing artificial single plants or single clusters at present. This method has the following disadvantages: 1, the aquatic vegetation of the natural water body is greatly damaged, so that the aquatic vegetation of the natural water body is possibly declined and even died; 2, the labor required in the planting and management process is huge, the efficiency is low, and particularly, the planting is carried out in a submerged state; 3 because the plants are influenced by the processes of collection, transportation, planting and the like, the activity of the aquatic plants is greatly reduced, the survival rate after planting is low, and the effect of improving the water quality of the water body is difficult to play.
Another method often used in current aquatic vegetation restoration work is to directly collect propagules or seeds from aquatic plants that can produce a large amount of seeds, and then to sow the propagules or seeds in the area to be treated for natural growth. Due to the limitation of water quality conditions and the biological characteristics of aquatic plants, the seedling rate of the propagules is very low, and the effect of treating the water environment cannot be achieved.
Disclosure of Invention
In order to solve the problems in the prior art, the invention provides the submerged turf planting method for improving the ecology of the hard riverway and the pond water, which effectively solves the problem that submerged plants are cultured in a small amount of sludge test fields to adapt to the natural condition of insufficient sludge in advance, and nutrient solution is added under the condition to ensure the growth trend of the submerged plants. The technical problem of low survival rate of the submerged plant hard riverway transplantation is solved; and the problems that the efficiency is low, the cost is high and the water quality of a water area is greatly fluctuated in the planting process because the traditional submerged plant is planted singly or planted by a single plant are solved. The finished product of the submerged turf greatly improves the working efficiency and reduces the pollution to water quality in the planting process; and the problem that large-scale machinery is usually applied to the traditional improvement of the ecology of hard riverways and pond ponds, the topography of a water area is changed to a greater extent, and side effects are caused to the ecology in the area is solved. The invention can be applied without changing the regional landform basically, and can achieve the effect of quickly and efficiently changing the ecology of the water area.

step 3, placing the braided fabric turf in a culture field, adding a water plant nutrient solution into the culture field, keeping the depth of the water plant nutrient solution at 5-20cm, and culturing for 7-14 days, wherein the thickness of sludge at the bottom of the culture field is less than 5 cm;
and 4, cleaning and leveling the water area of the turf to be transplanted, transplanting the braided fabric turf into the water area of the turf to be transplanted, and ensuring that the root system of the submerged plant is contacted with the bottom of the water area of the turf to be transplanted.
The submerged plant is sowthistle seedling or potamogeton gracilis or hydrilla verticillata, and the length of potamogeton verticillata, hydrilla verticillata or hydrilla aurantiaca is 8-30cm and part of leaves are reserved.
The area of the mesh plate is 50 x 50cm, and the density of the submerged plants on the mesh plate is 16-20 per plate.
In step 4, the braided fabric turf is fixed by the crushed water bottom stones in the area where the water flow of the water area of the turf to be transplanted is gentle, the water flow turbulent area of the water area of the turf to be transplanted is connected with each fixed braided fabric turf by the string, and the braided fabric turf is inserted into the small wooden stick and fixed at the bottom of the water area of the turf to be transplanted.
Compared with the prior art, the invention has the beneficial effects and advantages that:
1. the method is applied to hard riverways and pond ponds, namely water areas with less sludge at the bottom;
2. the water quality and landscape effect of the water area can be greatly improved after the Chinese herbal medicine skin is applied.
