specific Embodiment approach 1

[0012] Specific implementation mode one: a kind of method of using reed rhizome transplanting to rebuild and restore degraded wetland reed vegetation in this embodiment is carried out according to the following steps:

[0013] 1. Excavation and preservation of reed rhizomes: after the thawing depth of the surface soil reaches 15cm from the end of March to the first ten days of April in spring, in the natural growth place of reed communities, the reed rhizomes are excavated by interval patch method. Parameters in the excavation process: the patch interval is 30m~50m, the patch size specification is n×3n; where n=1~3, the unit is m, and the excavation depth is based on the excavation to the horizontal rhizome, and then the excavation The reed rhizomes are piled up, sprayed with water and covered with straw mats or straw to maintain humidity, and the reed rhizomes are preserved for transplanting;

[0014] In this step, before digging the reed rhizome patch, first cut off the dead...

specific Embodiment approach 2

[0024] Embodiment 2: This embodiment is different from Embodiment 1 in that: the storage time of reed rhizomes in step 1 is no more than 5 days. Other steps and parameters are the same as those in the first embodiment.

specific Embodiment approach 3

[0025] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that in Step 1, the plaque interval is 40 m. Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

A method for reconstructing and recovering degraded wetland Phragmites australias vegetation by Phragmites australias rootstock transplanting is provided. The invention belongs to wetland vegetation recovery and reconstruction methods, and particularly relates to a method for reconstructing and recovering degraded wetland Phragmites australias vegetation by Phragmites australias rootstock transplanting. The objective of the invention is to solve the problem that the conventional methods for recovering degraded wetlands by using Phragmites australias rootstocks is large in engineering quantity, is long in time, is slow in recovery speed, and is low in the survival rate of seedlings. The method includes: 1, Phragmites australias rootstock digging and storage; 2, turning and preparation of a transplanting land; 3, rootstock transplanting; 4, water supplying after planting, and weed clearing and management. The method is low in cost; in transplanting, a small hole vertical cutting type transplanting manner is adopted, furrow digging and ridge establishment can be avoided, and the engineering quantity is less; management mainly includes plowing and weeding before transplanting, and short-term water supplying and retaining after transplanting, and the working load is less; the method can save time, effort, and money, is fast in recovery speed, and is high in the survival rate of the Phragmites australias, and the survival rate can reach 90%.

Description

technical field [0001] The invention belongs to methods for restoring and rebuilding wetland vegetation, in particular to a method for rebuilding and restoring reed vegetation in degraded wetlands by transplanting reed rhizomes. Background technique [0002] Phragmites australis is a perennial herbaceous plant of the genus Phragmites australis, which is a perennial aquatic or wet tall grass. It has a wide range of adaptability to water, from moist soil to perennial water, from a few centimeters to more than 1 meter in water depth. Reed community. Reed wetlands are widely distributed and are important wetland landscapes in swamps, riversides, lakesides and other watery areas, and are also a typical type of marsh wetlands in northern my country. There are large areas of concentrated distribution of reed wetlands in North China, Northeast my country, Inner Mongolia and Xinjiang. Reed wetlands play an important role in purifying water pollution, regulating microclimate, provid...
