Example Embodiment

[0019] Specific implementation mode one: the method for quickly restoring the degraded reed wetland in this implementation mode is carried out according to the following steps:

[0020] 1. Select the degraded reed wetland in the reed wetland as the restoration area;

[0021] 2. Clear the litter on the surface of the restoration area to obtain the pretreated reed wetland restoration area;

[0022] 3. From March to April, excavate the surface soil of the reed wetland restoration area after pretreatment, and use bulldozers to move the surface soil of the reed wetland restoration area after pretreatment along the horizontal direction, and pile up the pushed soil into different piles. A continuous trapezoidal platform-shaped mound; the depth of the excavation is 30-40cm;

[0023] 4. The height of the accumulated trapezoidal table-shaped soil mound is 25-50cm.

Example Embodiment

[0024] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the depth of excavation described in step three is 35cm. Others are the same as in the first embodiment.

Example Embodiment

[0025] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the excavated and moved area in Step 3 is the same as the degraded area of ​​the reed wetland. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a method for rapidly restoring degenerated reed wet lands, relates to a restoring method of the degenerated reed wet lands, and aims to solve the problems that a degenerated wet land reed restoring method is single, high in investment cost, slow in restoring and not easy to popularize. The method includes the steps: firstly, selecting degenerated reed wet lands in reed wet lands as a resorting area; secondly, removing dry branches and fallen leaves on the earth surface of the resorting area to obtain a pretreated reed wet land resorting area; thirdly, digging surface soil of the pretreated reed wet land resorting area in March or April, moving the surface soil by the aid of a bulldozer along the horizontal direction, and stacking the pushed up soil into discontinuous trapezoidal soil piles. By the method, the degenerated wet lands in the resorting area can be resorted by 85% or more in year, germinating time of spring reeds in the resorting area are at least advanced for 10-15 days, the height of the reeds is improved by 30-40cm year on year, and biomass is improved by 30% or more. The method is used for resorting degenerated reed wet lands.

Description

technical field [0001] The invention relates to a restoration method of degraded reed wetland. Background technique [0002] Phragmites reed is a perennial herb of the Poaceae Phragmites genus, with thick and creeping rhizomes, and has two propagation methods: seed propagation and branch propagation. The plants of Phragmites reed are tall, with a stalk height of up to 3m, a diameter of up to 4cm, and more than 20 nodes; the leaves are flat, up to 45cm in length, and up to 3.5cm in width; they mostly grow in the edge areas of rivers, lakes, ponds and ditches, and are widely distributed in the wetlands of northern my country. [0003] Reed wetlands have important ecological functions in terms of windbreak and sand fixation, maintenance of biodiversity, climate regulation, water purification, and soil improvement. Due to the impact of climate change and irrational use, many reed wetlands are facing area shrinkage and functional decline. situation. [0004] For reed wetlands, ...
