Submerged-plant module making method

Abstract

The invention discloses a submerged-plant module making method. The method mainly includes the steps of 1), selecting submerged-plant propagules; 2), planting the propagules into nursery seedling plates; 3), placing the nursery seedling plates in a water pool for germination; 4), taking out germinated submerged-plant seedlings and planting the same in cultivation trays; 5), placing the cultivation trays into the water pool for domesticated growth. The method is low in cost, simple in operation and obvious in effect; species diversity of submerged-plant communities can be improved, and submerged plants can be planted in the water bottom effectively; the method is applicable to a lake aquatic vegetation restoration project, an aquatic plant community diversity improvement project, or a lake water ecosystem reconstruction project and the like.

Description

technical field [0001] The invention relates to the technical field of lake aquatic vegetation restoration engineering, the technical field of aquatic plant community diversity improvement engineering, or the technical field of lake water ecosystem reconstruction engineering, and especially relates to the technical field of submerged plant placement. Background technique [0002] At present, due to the serious situation of agricultural non-point source pollution, the destruction of forest vegetation, and the intensification of soil erosion and other problems in China, the nutrient content in water bodies continues to increase, the internal load of lakes continues to increase, and the problem of eutrophication is prominent. The eutrophication of the lake water causes the rapid growth of phytoplankton, reduces the transparency of the water body, causes weak light stress to submerged plants, reduces the distribution area of ​​submerged plants, reduces the biodiversity of submerg...

Problems solved by technology

For example, the invention patent with the publication number (CN103918424A) titled "A Planting Method for Submerged Plants in Plateau Shallow Lakes" introduced a method of wrapping the roots, clay and gravel of submerged plants with non-woven bags, and then fixing them by piling with bamboo poles. The planting method of submerged plants, which can effectively fix submerged plants, but the steps of wrapping with non-woven fabrics and fixing with bamboo poles are complicated and not conducive to subsequent management

The invention patent with the publication number (CN101015268A) titled "A Method for Planting Submerged Plants in Lakes" introduced a method for planting rootless submerged plants in a frame-type netted seedbed, although this method can effectively fix Submerged plants, but the frame-type mesh seedbed is complicated to make, and rootless submerged plants take root slowly in an environment without sediment, and the growth of clones is extremely slow

The invention patent with the publication number (CN1860854A) is titled "Quick Colonization Method of Lake Submerged Plants", which introduces a method of manually kneading clay in the outer layer of the soil to form a root system-soil sphere, adjusting the depth of the lake in the construction area and planting in the lake bottom mud The method of spheres, although this method can effectively colonize submerged plants and quickly build groups, but the steps of adjusting the water depth of the lake in the construction area and kneading each sphere are complicated and cumbersome, and the water in the construction area is discharged into other water bodies. Eco-efficiency to be assessed
