Problems solved by technology

These methods can suppress algae and moss to a certain extent, but they are time-consuming and labor-intensive, require a large amount of maintenance work, and have high costs. They also pose risks to the growth of aquatic plants such as bitter grass, and at the same time, they will damage the water ecosystem.

Embodiment 1

[0025] Example 1 Effect test of radish snails on algae attached to the surface of Erythrina

[0026] The experiment on the influence of radish snails on algae adhered to the surface of Erythrina chinensis lasted for 25 days. The radish snails used in the experiment were collected from East Taihu Lake. Considering that the in-situ food types of the radish snails may be different, in order to avoid interference with the experiment, the collected radish snails were placed in a plastic box without aquatic plants to cultivate about one. During the cultivation period, the snails feed on the organic matter in the sediment. The attached algae collection plate is a 3cm×3cm plastic plate with a smooth surface. The experimental containers are transparent cylindrical plexiglass cylinders with a height of 50 cm and an inner diameter of 15 cm.

[0027] In the experiment, a blank control group without snails and 5 groups with snails were set. The experimental groups of snails were set at 2...

Embodiment 2

[0044] Example 2 Applied to the control of surface attachments and moss on the surface of bitter grass in Xiaoshi River, Huzhou, Zhejiang

[0045] Xiaoshi River in Huzhou, Zhejiang, with a water area of ​​108,190m 2 , the water depth is 4.7 kilometers. Before the radish snails were put in to build a stable ecosystem, there were many surface attachments and mosses on the surface of the water body of Xiaoshi River. The water body landscape effect was not good, and the water body transparency was low (only 0.2-0.3 meters). According to the method that radish snails graze bitter grass and attach algae and moss, which can effectively reduce the amount of attached algae and moss, the density of radish snails is 162.3-270.5kg / 10,000m 2 , the specification is body length 1-2cm. After 45 days of dosing, the area of ​​moss no longer increases, the surface attachments of bitter grass are significantly reduced, the transparency of the water body reaches 1.5-2 meters, and the transparenc...

Abstract

The invention belongs to the field of water body ecological restoration, and particularly relates to a method for controlling eel grass surface attachments and moss by utilizing Radix Montfort. The method includes the following step of throwing the Radix Montfort in a water body where eel grass grows. The method does not use chemical medicament and plant medicament which have a negative impact onthe ecology of the water body and does not adopt expensive engineering measures, but the method adopts an ecological control method according to unique ecological habits of the Radix Montfort and ecological principles, which have not any adverse effects on environment and are of great significance for maintaining the stability of submerged vegetation in a eutrophication water body.

Description

technical field [0001] The invention belongs to the field of ecological restoration of water bodies, and in particular relates to a method for controlling surface attachments and moss of bitter grass by using radish snails. Background technique [0002] Radish snails belong to the genus Radix Snails belonging to the subclass Pneumoniae subclass Pulmonidae. It has a table spiral shell, the shell is thin and slightly transparent, the shell surface is dark grayish brown or light brown, with thin growth lines, 4 spiral layers, no husband. The head is flat and wide, with a snout at the front end and a split leaf shape extending left and right. Radish snails have strong adaptability and live widely in water bodies in various environments. The impact of pollution on feeding functional groups, which is conducive to accurate river ecological assessment), has great potential in monitoring and evaluation. [0003] Submerged vegetation is the key factor that determines the clear wate...
