Easy planting method for lake submerged plant through water interception

The invention relates to an easy planting method for lake submerged plant through water interception, which proposes that lake mud containing corresponding materials capable of helping submerged plant to propagate and grow, such as roots, stems, seeds and buds are used for quickly and easily plant the lake submerged plant in a planting area without underflow. In the easy planting method, a large planting area of more than 0.25 square kilometers and a small water interception area of 2500 to 10,000 square kilometers are surrounded by floating enclosures with full height or half height so as to prevent blue algae out of the planting areas and wind-driven lake current from damaging the plant in the planting areas; the method of dredging along a strip-shaped area biennially is utilized, the lake mud in the areas for helping the submerged plant to propagate and grow is dredged to obtain the materials capable of helping the submerged plant to propagate and grow, such as roots, stems, seeds, buds and the like, and t
