Problems solved by technology

[0003]There are some common problems in the water-fluctuation zone of the reservoir: ① Perennial flooding, water wave erosion and surface runoff take away a large amount of nutrients such as nitrogen, and the water-fluctuation zone The soil is severely drought, the soil is poor, the vegetation is difficult to survive and gradually shrinks, and the vegetation in most areas of the water-fluctuating zone has disappeared; ②Soil erosion is serious, and geological disasters such as landslides, collapses, and mud-rock flows often occur
The existing technology has defects such as poor growth of plants in the hydrofluctuation zone, poor flood resistance, poor biomass, difficult management and maintenance, and poor sustainability.

Embodiment 1

[0031] A method for restoring vegetation in a wetland drawdown zone based on Majiazi, comprising the following steps:

[0032] S1. Excavate planting holes: excavate planting holes within 1m from the revetment of the water-fluctuating zone, place a double-layer network structure woven by straw on the inner wall of the planting hole in advance, and fill the double-layer network structure with original planting of safflower seedlings earth;

[0033] S2, planting of sargassum: the seedling height is 25~40cm the sargassum seedlings are transplanted in the planting hole, the planting density of samurai is horizontal 30cm * vertical 30cm, gradually backfill the soil after fixing the seedlings, evenly arrange the nutrient soil on the surface, Then sow the plant seeds on the nutrient soil; water the fixed root water to complete the planting of the vetch;

[0034]S3. Cultivation of flood-tolerant herbaceous plants: When it is in the dry season and the soil humidity is 60-70%, spread th...

Embodiment 2

[0036] A method for restoring vegetation in a wetland drawdown zone based on Majiazi, comprising the following steps:

[0037] S1. Digging planting holes: excavate planting holes within 2.5m from the revetment of the water-fluctuation zone, and place a double-layer network structure woven by straw on the inner wall of the planting hole in advance. The layers are connected to each other. The mesh structure is filled with the original planting soil of the Majiazi seedlings;

[0038] S2, planting of sargassum: the seedling height is the 30~50cm of sargassum seedlings transplanted in the planting hole, the planting density of samurai is horizontal 40cm * vertical 60cm, gradually backfill soil after fixing the seedlings, evenly arrange nutrient soil on the surface, Then sow the plant seeds on the nutrient soil; water the fixed root water to complete the planting of the vetch;

[0039] S3. Planting of flood-tolerant herb plants: When it is in the dry season and the soil humidity is...

Embodiment 3

[0042] A method for restoring vegetation in a wetland drawdown zone based on Majiazi, comprising the following steps:

[0043] S1. Excavate planting holes: excavate planting holes within 1.5m from the revetment of the water-fluctuating zone, place a double-layer network structure woven by straw on the inner wall of the planting hole in advance, and fill the double-layer network structure with native seedlings planting soil;

[0044] S2, planting of sargassum: the seedling height is 25~50cm the sargassum seedlings transplanted in the planting hole, the planting density of samurai is horizontal 40cm * vertical 50cm, gradually backfill the soil after fixing the seedlings, evenly arrange the nutrient soil on the surface, Then sow the plant seeds on the nutrient soil; water the fixed root water to complete the planting of the vetch;

Abstract

The invention relates to the technical field of ecological management, and provides a wetland hydro-fluctuation belt vegetation recovery method based on paliurus ramosissimus, which comprises the following steps: S1, digging planting holes from a revetment of a hydro-fluctuation belt to a height of 1-2.5 m below the revetment, and placing a double-layer net-shaped structure woven by straws on the inner wall of each planting hole in advance, filling the double-layer net-shaped structure with paliurus ramosissimus seedling native planting soil; S2, transplanting paliurus ramosissimus seedlings into the planting holes; and S3, in the dry season and when the soil humidity is 60-90%, planting flood-resistant herbaceous plant seeds under the paliurus ramosissimus, and the sowing area accounts for 50-80% of the area of the hydro-fluctuation belt. The vegetation planted in the water-level-fluctuating zone of the reservoir has good drought resistance and barren resistance, can adapt to water level changes, and is good in growth vigor, high in water logging resistance, extensive in management and protection and high in sustainability; and the method is simple and good in restoration effect, and has important social effect and application value for restoration and treatment of the ecological environment.

Description

technical field [0001] The invention relates to the technical field of ecological management, in particular to a method for restoring vegetation in a wetland water-fluctuation zone based on vegetative seeds. Background technique [0002] Although economic technology, ecological environment, industrial development and historical background are different between China and foreign countries, the concentration points of vegetation restoration in water-fluctuating zones are generally the same. Domestic and foreign research on vegetation restoration in the water-fluctuation zone mainly focuses on the succession of vegetation in the water-fluctuation zone, the composition of vegetation in the water-fluctuation zone, the selection of suitable plants in the water-fluctuation zone, the research on the limiting factors of vegetation restoration in the water-fluctuation zone, and the research on the vegetation in the water-fluctuation zone. Vegetation restoration model research, etc. I...
