A method for improving the transparency of black and odorous water bodies and promoting the natural growth of submerged plants

The invention discloses a method for promoting natural growth of submerged plants by increasing the transparency of a black and odorous water body. According to the method, particulate matters depositing at a mud-water interface are dispersed to overlying water through mechanical or jetting flushing in a relatively closed water body formed by a mud surface and a solid border, and meanwhile overlying water turbulent flow limited by the solid border is formed; turbulent flow contents are adequately washed away by virtue of the overlying water turbulent flow, and therefore, the particulate matters with different particle sizes are further dispersed into the overlying water; particle size gradient distribution is generated under the action of gravity and a fluid force along the direction of gravity; rough particles deposit to cover bottom mud to form a stable deposition layer, and fine particles, namely suspended particles are transferred out of water through flocculent precipitation; and after a certain period of time, the water body can be crystal clear and can meet light conditions of the submerged plants. The submerged plants need to be timely planted in a water area in which submerged plants do not naturally grow in spring or a relatively deep water area so as to gradually restore self-cleaning capacity of the water body, and the conversion of water ecology is promoted.
