River-linked lake shallow water vallisneria seedling lotus leaf and mud wrapped planting method

Abstract

The invention discloses a river-linked lake shallow water vallisneria seedling lotus leaf and mud wrapped planting method. The river-linked lake shallow water vallisneria seedling lotus leaf and mud wrapped planting method comprises selecting planting areas with a water depth of 0.5-0.8 m and water transparency of 40 cm and with the bottom mud applicable to providing sufficient nutrition for vallisneria; wrapping a bundle containing 3-4 vallisneria seedlings into wet natural lake bottom mud at a height of 15-20 cm, with a bottom diameter of 10-15 cm and in a cylindrical shape; then integrallywrapping the wrapping mud with free lotus leaves but exposing the seedlings, tightening the lotus leaves at the exposed seedlings with straw, and shearing off superfluous lotus leaves higher than thewrapping mud; arranging the wrapping mud with the vallisneria seedlings on water at an interval of around 5 m so that the vallisneria can fall down to the water bottom and grow up naturally. The river-linked lake shallow water vallisneria seedling lotus leaf and mud wrapped planting method solves the problem of vallisneria artificially planting difficulty in shallow water and can help rapidly restore lake ecological functions.

Description

technical field [0001] The invention relates to an aquatic vegetation ecological restoration technology, in particular to a method for planting seedlings of Vallisnerianatans (Lour.) Hara wrapped in soil with lotus leaves in shallow water areas of Tongjiang shallow lakes in spring. Background technique [0002] Together with the rivers, the river-connecting lakes in the Jianghuai Basin constitute a unique river-lake compound wetland with a wide distribution and a large area. The submerged vegetation in these Tongjiang lakes has been well developed in history and bred rich biodiversity, which plays an important role in maintaining the stability and ecological security of the Tongjiang lake wetland ecosystem. With the development of the economy, the utilization intensity of wetland resources has gradually increased, and the ecological process of lake wetlands has been seriously disturbed. In recent years, due to the rapid development of the aquaculture industry, especially th...

Problems solved by technology

For the colonization of submerged plants, especially bitter grass, the current method is time-consuming and laborious, especially in wetlands with a water depth of less than 1m, it is difficult to directly colonize submerged plants manually
