Embodiment Construction

[0031] Attached below figure 1 And the example details:

[0032] 1. Preparation method

[0033] ①Select seedlings

[0034] From March to August, choose submerged plants that grow vigorously: foxtail algae, micro-toothed vegetable, twisted leaf vegetable, black algae, perforated leaf vegetable, light leaf vegetable, take the top 15-20cm As the seedling 1, leaves below 5 cm from the bottom of the seedling 1 were removed.

[0035] ②Set up the planting pot

[0036] The planting pot 2 is a cuboid plastic container with a length of 50 cm * a width of 30 cm * a height of 8 cm. The bottom of the container is filled with 2-3 cm thick clay 3, and then covered with a fishing net 4 with a 1 cm aperture. The size of the planting pot 2 can be determined according to the Plaque size selection is required.

[0037] ③ planting seedlings

[0038] Insert the selected seedlings through the fishing net 4 of the planting pot into the clay 3, insert a seedling 1 every 3 to 5 cm, and then sprea...

Abstract

The invention discloses a preparation method of a submerged vegetation patch, which relates to the technical field of the ecological environment engineering, and comprises the following steps that: 1, selecting a seedling: the top end of a submerged plant with vigorous growth is selected as a seedling; 2, setting a planting pot: the planting pot is a cubic vessel, clay is arranged on the bottom part of the vessel, and then a layer of fishing net is paved on the clay; 3, planting the seedling: the well-selected seedling passes through the fishing net of the planting pot to be plugged inside the clay; 4, placing the planting pot into a pool: the planting pot with the seedling is placed into a pool; 5, managing the seedling in a later stage: the water depth is gradually increased until the seedling grows to the required height; and 6, putting a patch: the prepared patch is arranged on the bottom part of the water to be restored. The preparation method is simple, the cost is low, and the effect is remarkable; the water quality can be effectively improved, the diversity of the submerged plant can be increased, and the stability of the aquatic ecological system can be strengthened; and the preparation method is suitable for restoration engineering of lake aquatic plant and lake aquatic plant diversity or for the ecological rebuilding engineering of the lake aquatic ecological system.

Description

technical field [0001] The invention relates to the technical field of ecological environment engineering, in particular to a method for preparing submerged vegetation patches. Background technique [0002] At present, due to the widespread problems of substandard discharge of polluted water bodies, forest vegetation destruction, and intensified soil erosion, the nitrogen and phosphorus loads of rivers, lakes and other receiving water bodies have increased, water transparency has decreased, and water eutrophication has become prominent. A series of ecological problems such as the shrinking of the aquatic vegetation area and the sharp decline in biodiversity, and the transformation of the grass type-clear water state of the lake to the algae-turbid water state have become more and more prominent. [0003] Submerged vegetation is one of the important components of the lake aquatic ecosystem, and it has important ecological significance in maintaining the stability of the aquat...
