Problems solved by technology

However, due to the perennial occurrence of algal blooms, the transparency of the lake is extremely low, and it is extremely difficult to plant submerged plants. In addition, the strong wind speed in Dianchi Lake makes it even more difficult to plant submerged plants.

Embodiment 1

[0025] The problem of eutrophication in the outer sea of ​​Dianchi Lake is prominent. Algae blooms occur all year round. The transparency of the water body is extremely low, and the wind and waves are strong in winter and spring. In the spring of 2013, the applicant planted submerged plants in the shallow waters of the lakeside section of the outer sea. The following steps were taken:

[0026] 1. Select submerged water plants such as black algae, hornwort, foxtail algae, and weeds with longer plants, and the plant height is 1.5-2m;

[0027] 2. The preparation of planting monomers, materials include planting clay, thin nylon rope, water-permeable non-woven bags, gravel, etc. Fill the cloth bag with a small amount of gravel, and finally fasten the cloth bag with a thin nylon rope to ensure that the length of the rope is 2-2.5m;

[0028] 3. The water body is planted with bamboo piles, and the water depth for submerged plants is selected to be 1-1.5m; choose bamboo poles with a di...

Abstract

The invention belongs to the technical field of environment engineering and particularly relates to a planting method of plateau shallow lake submerged plants. The method includes: selecting submerged plants more than 1.5m in height; preparing a single planting bodies, building a water planting strip, selecting bamboo poles 5-10cm in diameter to manufacture bamboo poles of the same height of 3-3.5cm, and using the bamboo poles for piling; tying the thin nylon ropes of each single planting body to the thick rope between two piles, slowly placing the single planting body in water for planting, allowing the distance between every two single planting bodies to be 25-40cm, and allowing the plants to float on water after planting; planting management. By the method, vegetation coverage of plateau shallow lakes rich in nutrition, and by large-scale planting, water can be improved, water transparency can be increased, and blue-green algae outbreak can be inhibited.

Description

technical field [0001] The invention belongs to the technical field of environmental engineering, and in particular relates to a method for planting submerged plants in plateau shallow lakes. Background technique [0002] As an important part of wetlands, lakes play an important supporting role in the development of social economy. However, in recent years, due to the rapid development of social economy and the continuous increase of population, many lakes have been seriously eutrophicated, the ecological functions of lakes have been seriously degraded, biodiversity has decreased, and the purification capacity of the system has basically lost, resulting in aggravated pollution severity. , which has seriously affected the sustainable socio-economic development within the basin. Protecting and treating polluted lakes and restoring their ecological functions has become one of the hot issues of social concern. [0003] Aquatic plants are an important part of the freshwater lak...
