Embodiment

[0029] Such as figure 1 and figure 2 Shown is a structural schematic diagram of a saline-alkali land ecological drainage ditch of the present invention, the width of the ditch bottom is designed to be 50cm, the ditch depth is 200cm, and the slope foot is 60°.

[0030] The drainage ditch structure includes a drainage ditch body 1. A base carpet layer 2 is laid on the drainage ditch body 1. A reed layer 3 is planted in the middle of the base blanket layer 2. Artemisia layers 4 are respectively planted on both sides of the reed layer 3. Each Artemisia layer 4 The side far away from the reed layer 3 is planted with a Suaeda layer 5, and each Suaeda layer 5 is planted with a mixed layer 6 away from the side of the Artemisia layer 4, and the mixed layer 6 is composed of reeds, foxtail grass and Suaeda salsa, and the reed layer 3 , Artemisia layer 4, Suaeda salsa layer 5 and mixed layer 6 together constitute the vegetation blanket of saline-alkali land.

Abstract

The invention discloses a saline-alkali land ecological drainage ditch structure and a rapid construction method thereof. Artemisia layer, each Artemisia layer is planted with Suaeda salsa layer on the side far away from the reed layer, and a mixed layer is planted on the side of each Suaeda layer away from the Artemisia layer, the mixed layer is composed of reed, dogtail grass and Suaeda salsa, and the reed layer , Artemisia layer, Suaeda salsa layer and mixed layer together constitute the vegetation blanket of saline-alkali land. The saline-alkali land ecological drainage ditch based on the vegetation distribution law of the present invention can not only realize the rapid reconstruction of the drainage ditch ecosystem, but also overcome the shortcomings of the traditional soil ditch, masonry slope protection drainage ditch and traditional ecological drainage ditch; it has high stability , good water and soil conservation effect; low cost, simple construction, and also has the function of landscape and filtering and purifying farmland surface runoff and underground drainage.

Description

technical field [0001] The invention belongs to the technical field of ecological system construction, and in particular relates to an ecological drainage ditch structure in saline-alkali land, and also relates to a rapid construction method of the drainage ditch structure. Background technique [0002] Among the various measures to improve saline-alkali soil, drainage is a fundamental and key measure. Improving drainage facilities can accelerate the discharge of salt in soil and groundwater leached from salt washing, irrigation and rainfall; and reduce the groundwater table to prevent Saline groundwater migrates to the surface, causing soil salt accumulation and surface salt return. Open ditch drainage is one of the main methods of drainage in saline-alkali land, which can regulate regional hydrological conditions, promote soil desalination, and improve soil texture. However, drainage also accelerates the output of non-point source pollutants such as pesticides and fertili...
