specific Embodiment approach 1

[0013] Specific implementation mode one: the method for quickly recovering degraded Suaeda salsa wetland in this implementation mode is carried out according to the following steps:

[0014] 1. Select the degraded Suaeda salsa wetland as the area to be restored in Northeast China;

[0015] 2. From March to April, use a rotary tiller to shallowly plow the degraded area to be restored. The depth of shallow plowing should not exceed 5cm, and the original topography should be maintained;

[0016] 3. There is no need for artificial watering after shallow plowing. When the spring and summer rains come, they will germinate and reproduce by themselves.

specific Embodiment approach 2

[0017] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the degraded Suaeda salsa wetland described in step 1 is a partially degraded Suaeda salsa wetland. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0018] Specific embodiment 3: This embodiment differs from specific embodiment 1 or 2 in that: the depth of shallow turning in step 2 is 1-4 cm. Others are the same as in the first or second embodiment.

Abstract

The invention discloses a method for rapidly recovering a degenerative alkaline wetland, and relates to a method for recovering a degenerative alkaline wetland. The method aims at solving the problem that an existing method for recovering the degenerative alkaline wetland is high in recovery cost and not high in applicability. The method comprises the steps that 1, the degenerative alkaline wetland is selected in Northeast China region as the region to be recovered; 2, in March and April, a rotary cultivator is utilized for carrying out shallow ploughing on the degenerative region to be recovered, the shallow ploughing depth is not larger than 5 cm, and the original landform is kept; and 3, manual watering is not needed after shallow ploughing, and sprouting and growing are automatically achieved after rain comes in spring and summer. According to the method, sowing is not needed, and the seed purchasing and sowing recovery cost can be greatly reduced. The method is easy, convenient to practically operate and good in popularization performance and application prospect. In the same year, the coverage degree of the alkaline wetland can reach 50%-80%, and the recovery speed is improved by 2 years or longer compared with natural recovery. The method is used for recovering the degenerative alkaline wetland.

Description

technical field [0001] The invention relates to a restoration method of degraded saline-alkali wetland. Background technique [0002] Suaeda salsa (L.) is an annual succulent true halophyte herb, belonging to Chenopodiaceae (Chenopodiaceae) Suaeda, commonly known as Salsa, Suaeda salsa, Salt Artemisia, Tiger Tail, Monk Head, Pig Tail, Artemisia salina, etc., the plant height is generally 50-80cm, and they are mainly distributed in saline-alkali wastelands such as seashores, lakesides, and deserts. Suaeda salsa has physiological characteristics such as saline-alkali tolerance, low temperature tolerance, barren tolerance, and humidity-loving nature, and is an indicator species for changes in saline-alkali wetlands. When saline-alkali wetlands are degraded, the Suaeda salsa wetlands tend to show shorter plant heights, lower coverage, alkali spots, and even bare land without grass. Suaeda salsa mainly relies on seeds for propagation. At present, the artificial planting technol...
