specific Embodiment approach 1

[0013] Specific implementation mode one: the protection and restoration method of cattail wetland in this implementation mode is realized according to the following steps:

[0014] 1. Select the cattail community with a life history of more than 3-4 years as the target community;

[0015] 2. Before the cattail seedlings germinate in spring, remove the withered leaves in the target community, turn the roots of the cattail out to the surface and grind them to obtain the pretreated target community;

[0016] 3. Excavate multiple horizontally spaced rectangular patches in the target community after pretreatment, the width of each rectangular patch is no more than 2 meters, the distance between each patch is 2 to 3 meters, and the excavation depth is 30 to 40 cm. Complete the protection and restoration of cattail wetlands.

[0017] Step 3 of this embodiment reserves a rectangular space no more than 2 meters wide because the annual growth and extension of the cattail underground ro...

specific Embodiment approach 2

[0019] Embodiment 2: This embodiment is different from Embodiment 1 in that the cattail community with a life history of 3-4 years is selected as the target community.

[0020] In this embodiment, the cattail community with a life history of 3-4 years is selected as the object of protection and restoration, based on the fact that the cattail community in this life cycle is in the grass-growing period of the community, and has a strong underground rhizome, which is more conducive to creeping growth to the surrounding area. .

specific Embodiment approach 3

[0021] Embodiment 3: This embodiment is different from Embodiment 1 in that the cattail community with a life history of 5-6 years is selected as the target community.

[0022] In this embodiment, a cattail community with a life history of more than 5-6 years is selected. The rhizome of the community has a relatively high density in the soil. Because it is often squeezed and thinned, the expansion space is insufficient, and the reproductive capacity of the rhizome begins to decline, so it needs to be protected in time. and restore.

Abstract

The invention relates to a cattail wetland protection and recovery method and belongs to the field of protection of cattail wetlands. The cattail wetland protection and recovery method aims at delaying the process that cattail communities enter a withered period or solving the problem that the cattail communities which grow consecutively for years begin to degrade. The cattail wetland protection and recovery method comprises the steps that (1) a cattail community with the life history of three to four year or longer is selected to serve as a target community; (2) withered leaves in the community are removed, and the roots of cattail are dug out; (3) a plurality of rectangular patches arranged at intervals in the horizontal direction are dug in the target community, and the protection and recovery of the cattail wetland are completed. According to the cattail wetland protection and recovery method, the mode of digging the abreast rectangular patches is adopted, the death of the old roots in the patches is accelerated, and growing space is provided for newly-grown root systems. By means of the cattail wetland protection and recovery method, the cattail wetland can be effectively prevented from degrading in large area, and the obvious recovery effect is especially achieved on the cattail community which begins to degrade.

Description

technical field [0001] The invention belongs to the protection field of cattail wetlands, and in particular relates to a method for protecting and restoring cattail wetlands that have grown for many years or have begun to degenerate. Background technique [0002] Cattail is a perennial herbaceous plant, which is mostly distributed in shallow water such as lake shores, swamps, ponds, ditches, etc., and generally grows in clusters. The alias of cattail is also known as cattail and cattail. Because of its candle-like spikes, it is also called water candle. The plant height of cattail is generally between 1.4-2.5m, and its leaves are long and narrow, alternate in two rows, 40-70cm long (some as long as 1m), 2-3cm wide, dark green in color, light and soft, The mesophyll tissue is a hollow rectangular cell, which has typical structural characteristics of hygrophytes. Cattail flowers are yellow-green, with slender, cylindrical flower spikes, closely connected male and female infl...
