A planting method and application of Suaeda salsa in coastal flats

Abstract

The invention belongs to the technical field of plant planting, and discloses a planting method and application of Suaeda salsa in coastal flats, step 1, planting areas, selecting suitable planting areas in the mid-tidal zone and high-tide zone of the intertidal zone, and constructing a wave-stopping belt; Step 2, sowing, the selection of temperature, seeding rate, and sowing time; Step 3, post-sowing management, covering the net, draining water and preventing flooding. Step 1 specifically includes: selecting an area suitable for planting in the mid-tidal area and high-tide area of ​​the intertidal zone; building a wave-resisting belt in the direction of the tidal water, building a dam in the offshore direction of the planting area, or planting reeds and tall straw in the direction of the tidal water in the planting area , Bamboo pole. The invention plants the Suaeda salsa in the suitable environment of the tidal flat, increases the growth area of ​​the Suaeda salsa, restores the habitat of the Suaeda salsa in the tidal flat, and provides support for the stability of the biological diversity of the tidal flat.

Description

technical field [0001] The invention belongs to the technical field of plant planting, and in particular relates to a planting method and application of Suaeda salsa in coastal flat salt land. Background technique [0002] At present, Suaeda salsa is a suitable plant for coastal tidal flats and a pioneer plant in saline-alkali tidal flats, which plays an important ecological role in tidal flat improvement and biodiversity. Coastal flats are divided into intertidal zone, subtidal zone and supratidal zone according to the law of tidal activity. The intertidal zone is divided into the following three areas according to the degree of flooding and the length of the duration: (1) high tide zone (upper zone): it is located in the uppermost part of the intertidal zone, the upper boundary is the spring tide high tide line, and the lower boundary is the neap tide high tide Wire. (2) Mid-tide area (middle area): It accounts for most of the intertidal zone, with the upper boundary bei...

Problems solved by technology

The large-scale reduction of Suaeda salsa will inevitably have a negative impact on the survival of some rare birds

[0004] Through the above analysis, the existing problems and defects of the prior art are: (1) the existing Suaeda salsa planting technology in salt land is implemented under the current situation that can effectively regulate water management. Suaeda salsa is mainly cultivated for food, and it is often cultivated in greenhouse facilities

(2) In the practice of restoration of coastal wetland biodiversity, some units or regions have carried out the restoration of plant community habitats with Suaeda salsa as the main body, but the restoration areas are mainly in the tidal flat zone, and occasionally In the high tide area of ​​the intertidal zone, Suaeda salsa in the middle tidal zone of the intertidal zone relies on natural colonization to successfully form a stable community.

The main reason is that the seeds of Suaeda salsa are small and light, the seedlings are not firmly rooted, and it is easy to lose from the planting area after high-intensity seawater erosion

(3) The middle and high tide areas in the intertidal zone are often flooded for a long time. If the beach surface is not exposed to water during the time of sowing and emergence, it is difficult for Suaeda salsa to emerge and survive

[0005] The difficulty in solving the above problems and defects is: (1) How to effectively avoid long-term flooding in the planting area and ensure that the time period for the seedling emergence of Suaeda salsa is enough to expose to water
