A method of constructing and constructing a silt intertidal tidal tidal zone in the estuary that is not suitable for forests

Abstract

The invention discloses a method for constructing and building arbor wave-eliminating forest belt on non-forestry river mouth sludge intertidal zone beach, wherein the method belongs to the technical field of agricultural cultivation. The method comprises the following steps of A, manual ditching and fetching soil for manufacturing piers and lifting ground; B, planting arbor container seedlings; C, performing mechanical soil working and planting a mangrove forest; D, planting intersected arbors in a mangrove planting area; and E, performing ditch cleaning and supporting, thereby improving tree growth and beach siltation. The method of the invention has functions of realizing normal growth of arbor trees such as Casuarina equisetifolia on the wetland of the non-forestry river mouth sludge intertidal zone beach, improving survival rate of the protection forest, successively applying creation of wave-eliminating forest belt on the wetland of the non-forestry beach, facilitating restoring and reconstruction of the biological system on the wetland of the non-forestry beach, facilitating resistance for great natural disasters such as typhoon and flooding tide at coastal regions, and performing a positive function on economic development of Chinese sea.

Description

technical field

[0001] The invention belongs to the technical field of agricultural cultivation, and relates to a method for afforestation on tidal flat wetlands, in particular to a method for constructing and constructing a tidal arbor wave-dissipating forest belt in a muddy intertidal zone of an unsuitable forest estuary. Background technique

[0002] The estuary refers to a section of the river that enters the sea and is affected by the tide. It is the water area between the land and the ocean, also known as the tidal section. The intertidal zone is the area between the high tide line and the low tide line, usually also called tidal flats. According to the law of tidal activity, the intertidal zone is divided into the following three areas: (1) high tide zone (upper zone): it is located in the uppermost part of the intertidal zone, the upper boundary is the high tide line of spring tide, and the lower boundary is the high tide line of neap tide. (2) Mid-tide area (middle...

Embodiment Construction

[0025] The present invention will be further described below in conjunction with embodiment.

[0026] The invention provides a method for constructing and constructing an arbor wave-dissipating forest zone in muddy intertidal tidal flats of estuaries that are not suitable for forests, and the constructing and constructing method includes the following steps.

[0027] A. Manually dig trenches and use soil as piers to raise the ground: From January to February every year, artificially dig trenches in the muddy intertidal zone tidal wetland elevation of coastal estuaries that are 10m-60m offshore and are not suitable for forests, or in high and high tide areas with slightly higher terrain 1. Take soil as a pier, reduce salt and lighten it, and then dig a drainage ditch perpendicular to the river bank or coastline, and use the soil dug out of the drainage ditch to pile up the mounds on both sides of the ditch, which can reduce the mound at the same time salinity and groundwater le...
