Embodiment Construction

[0019] Referring to the aforementioned method, the inventor planted 2500m of Clariscus pinnata in the tidal flats of the estuary of the Beilun River in Guangxi in 2013. 2 , the specific planting conditions are as follows:

[0020] 1. Soil preparation in the planting area. Artificial dredging is adopted to raise the tidal flat elevation by 20cm to 60cm, forming fine sandy tidal flats for the planting area of ​​bristle-like bristles, and the tidal flat elevation is approximately equal to the local average sea surface line. The tidal flat was relatively flat after artificial land preparation, but soon the tide caused the internal tidal flat to be slightly lower and the drainage was poor, so an artificial tidal trench system was built. The construction method is as follows: According to the observation of the tidal flow velocity and direction in the planting area, a main tidal ditch is set up, with a width of 2m to 4m and a depth of 70cm to 100cm; another 4 branch tidal ditches a...

Abstract

The invention discloses a method of applying scirpus subulatus in a tidal wetland to carry out ecological restoration. The method mainly comprises the steps of (1) comprehensively selecting a grass-friendly beach; (2) constructing a tidal creek system; (3) selecting field planting time; (4) optimizing provenance and collecting seedlings with soil; (5) carefully transporting the seedlings; (6) specifying a field planting method; (7) sufficiently applying base fertilizer and topdressing; and (8) enhancing initial management and protection. The practice demonstrates that survival and growth of the scirpus subulatus transplanted in the tidal wetland can be significantly promoted by using the method to plant the scirpus subulatus in the tidal wetland, effective restoration and sustainable development of coastal wetland ecosystems can be promoted, and certain economic benefits can also be obtained.

Description

technical field [0001] The invention belongs to the technical field of tidal wetland ecological restoration, and in particular relates to a method for carrying out ecological restoration in tidal wetland by using Claris pinnata. Background technique [0002] Scirpus subulatus Vahl is a plant of the Cyperaceae family that grows on both sides of coastal rivers, ditches beside fish ponds, drains and mangrove forest margins. It is widely distributed in Zhejiang and Fujian in my country. , Guangdong, Guangxi, Hainan, Hong Kong and China Taiwan and other places. The plants of Claris pinnata are upright, with lush growth and elegant and clean color. It is an excellent waterscape plant for ponds and river banks, and also an excellent aquatic plant for ecological restoration of coastal saline-alkali land and wetlands; benthos and swimming animals Abundant, it attracts waterfowl to feed or build nests in it; it has strong pollution resistance and can be used as a purifying plant; the ...
