Embodiment 1

[0024] figure 1 It is a structural schematic diagram of the present invention, figure 2 yes figure 1 A top view of the middle slope, combined with figure 1 , figure 2 As shown, a geocell type ecological ditch, the cross section of the ditch is trapezoidal, the side slope of the ditch is covered with a layer of cross-plastic wire mesh 1, and the cross-plastic wire mesh is covered with a mesh cell 2. The plastic barbed wire 1 is mainly used to fix the slope soil layer of the ditch, and the mesh cell 2 has the function of fixing and is used for planting plants at the same time. Slope protection plants 3 are planted in the mesh cell 2, and hygrophytes 4 are planted at the bottom of the ditch. In practice, the slope protection plants 3 are selected from one or more of tall fescue, bermudagrass, alopecia, and wild carrot, and are used to reinforce the side slope of the ditch. The wet plants 4 are selected from one or more of watercress, clover, arrowroot, and canna, and are u...

Abstract

The invention relates to a geo-cell type ecological ditch. The cross section of the ditch is ladder-shaped; a layer of plastic plated wire mesh (1) is respectively covered on the side slopes of the ditch; reticular cells (2) are covered on the plastic plated wire meshes (1); slope protection plants (3) are planted in the reticular cells (2); and hygrophytes (4) are planted at the bottom of the ditch. The ecological ditch provided by the invention is used for decreasing the water and soil loss, controlling the agricultural non-point source pollution, keeping the ecological diversity of the farmlands and the habitats of the animals and plants, beautifying the peripheral landscape environment, providing a growth platform for the plants and purifying the water quality and has the advantages of being convenient in construction, rapid in installation and simple and convenient in maintenance.

Description

technical field [0001] The invention belongs to the field of farmland drainage and irrigation systems, and relates to a farmland ecological interception channel, in particular to a geocell type ecological ditch, which is used to reduce soil erosion, control agricultural non-point source pollution, and maintain farmland ecological diversity and animal and plant habitats . Background technique [0002] Farmland irrigation and drainage ditches are an important part of the farmland ecosystem. They can not only absorb nutrients such as nitrogen and phosphorus output from farmland runoff, but also serve as extremely important habitats and refuges for small animals. Ecological ditch is a new type of ecological engineering technology, mainly composed of engineering measures and plant systems. Aiming at the current phenomenon of single inflow and drainage function of small rural ditches, significant damage to ditches structure, and accelerated hardening trend, the ecological ditch...
