Method for planting submergent plant in lake

Abstract

The invention relates to a method for planting submergent plant in lake, which in detail relates to a method for planting aquatic weed. It is characterized in that it comprises following steps: selecting aquatic weed variety: selecting aquatic weed of no root, long plant and early germination; preparing seed bed: preparing framed net platform; replanting aquatic weed: planting aquatic weed into seed bed; fixing aquatic weed: managing seed bed: moderating seed bed position; forming new aquatic weed community; moving seed bed to weedless area for continuous growth. The method can plant submergent plant in water with depth of 1.5- 2.0 meter and transparency of lower than 50 cm, the submergent plant can grow perpetually and it is helpful to improvement and stability for aquatic ecologic environment.

Description

technical field [0001] The invention relates to a method for planting submerged plants in a lake, in particular to a method for planting aquatic plants. Background technique [0002] Aquatic plants can be used as bait for aquatic animals such as fish, shrimp, and crabs, as well as attachments of fish eggs and shelters for shrimps and crabs when they moult, and have the function of regulating the ecology of water areas. The current methods of planting aquatic plants can be divided into two types: sowing or transplanting, and the varieties of aquatic plants to be planted can be divided into three types: floating plants, emergent plants and submerged plants. The method of planting floating plants and emergent plants is relatively simple. Generally, colonies can be formed quickly after transplanting or sowing. When planting submerged plants, the water level and water transparency often affect their normal photosynthesis, so planting is more difficult. Big. When planting submer...

AI Technical Summary

Problems solved by technology

Its disadvantages are: 1. It is necessary to lower the water level for sowing or replanting; 2. The water level should not rise too much, otherwise it will be difficult for grass seeds to germinate or cause aquatic plants to rot; 3. This method can only be used in waters where the water level can be artificially regulated ; 4. When the transparency of the water body is less than 30 cm, aquatic plants are not easy to survive

The method of planting submerged plants in lakes is not only labor-intensive, but also the planting of aquatic plants is not easy to succeed. The disadvantages are: 1. The planted submerged plants are easily impacted by wind and waves and float up; 2. The water level in the dry season of the planting area is required to be lower than 1 3. When the water level in the planting area exceeds 1.5 meters, it is difficult to plant and the survival rate is low. After the fence is removed, it is difficult for the planted aquatic plants to survive; 4. When the water transparency is less than 50 cm Aquatic plants are not easy to survive

Due to the existence of the above defects, it is difficult to popularize and apply the existing submerged plant planting methods in lake areas with a water depth exceeding 1.5 meters.
