Embodiment 1

[0021] In late March 2004, reed rhizomes were collected at the lakeside of Taihu Lake in Wuxi, Jiangsu Province, put into buckets, filled with water to immerse the rhizomes, brought back indoors on the same day, placed in artificial climate chambers, and adjusted the temperature to 4°C. In addition, a piece of waterside environment 1 of 2 square meters below the perennial water level 100cm is surrounded by the water barrier 2 ( figure 1 a), drain with a water pump. The reed rhizomes were taken out from the artificial climate chamber in early April, and then cut into sections 4 of the reed rhizomes, each section with a dormant bud. Generally, a reed rhizome can obtain 4 to 7 sections. Plant reed rhizome subsection 4 according to the equidistant interval of about 40cm, make dormant bud be positioned at about 1cm below the ground surface ( figure 1 b). By the beginning of May, the germination rate of rhizome 4 of Phragmites reed reached 98%. Treat that reed seedling 5 grows t...

Embodiment 2

[0023] In late March 2004, reed rhizomes were collected from the shore of Taihu Lake in Wuxi, Jiangsu Province, put into a bucket, filled with water to immerse the rhizomes, brought back indoors on the same day, and placed in an artificial climate chamber with the temperature adjusted to 2°C. In addition, a piece of waterside environment 1 of 3 square meters below the perennial water level of 20cm is surrounded by water barriers 2 and drained with a water pump. The reed rhizomes were taken out from the artificial climate chamber in early April, and then cut into sections 4 of the reed rhizomes, each section with a dormant bud. Generally, a reed rhizome can obtain 4 to 7 sections. Plant reed rhizome section 4 according to the equidistant interval of about 50cm, make dormant bud be positioned at about 1cm below the ground surface. By the first ten days of May, the germination rate of reed rhizome 4 reached 95%. When the reed seedlings grow to a certain height (greater than 20c...

Embodiment 3

[0025] In late March 2004, reed rhizomes were collected at the lakeside of Taihu Lake in Wuxi, Jiangsu Province, put into buckets, filled with water to immerse the rhizomes, brought back indoors on the same day, placed in artificial climate chambers, and adjusted the temperature to 6°C. The reed rhizomes were taken out from the artificial climate chamber in early April, and then cut into sections 4 of the reed rhizomes, each section with a dormant bud. Generally, a reed rhizome can obtain 4 to 7 sections. On a waterside environment 1 of 4 square meters where there is no accumulated water on the surface all year round, there is no need to build water barriers 2 . Plant reed rhizome section 4 according to the equidistant interval of about 60cm, make dormant bud be positioned at about 1cm below the ground surface. After this, no manual work is performed. By the first ten days of May, the germination rate of reed rhizome 4 reached 100%. When observing at the end of October, it ...

Abstract

A method for constructing a reed nunja at the side of water body in order to clean water and suppress the eutrophication of water body includes such steps as low temp activating of reed rhizome, cutting short to become segments with one dormant bud for each segment, planting them on the bed isolated with water body at the intervals of 40-60 cm in the season at 15-25 deg.C, flooding the bed after the segments of reed rhizome are survival, and natural reproduction.

Description

technical field [0001] The present invention relates to a method for constructing reed wetlands near water, which is a method for cultivating reeds and ecologically constructing reed wetlands in lakeshores, riverbanks, coasts and other waterside environments according to the ecological habits and needs of reed plants, so as to realize the purification of water quality , The method of suppressing eutrophication of water body. It belongs to the technical field of environmental protection. Background technique [0002] The pollution of lakes in our country is serious, more than 80% of the lakes are polluted, and many lakes have not reached the Class III water quality standard. More than 65% of the lakes in my country have reached eutrophication, and the lakes in transition from mesotrophic to eutrophic account for 20% of the total lakes. Algal blooms have occurred in many lakes, and red tides have occurred frequently in bays, and their area, intensity, and algal toxin content...
