However, in order to achieve anti-seepage and water retention, the channel adds soil modifiers to the soil after sodium treatment, which poses a potential threat to the soil, and the use of geotextiles and soil modifiers is not economical.

Abstract

The invention relates to a soil-property ecological ditch constructing method. The method comprises the steps of ditch digging: a compact clay layer is laid on the side wall of the ditch and / or the bottom of the ditch, a pebble layer is built at the bottom of the ditch, shrub twigs are cultured and planted, the shrub twigs are transplanted to the ditch, moss plants are transplanted to the ditch, aquatic plants are transplanted to the ditch, shading caring is conducted, and water is introduced. By means of the method, the loss of water in a ditch system can be reduced, the ditch construction cost is reduced, the plant survival rate is improved, a field landscape effect is achieved, the practicability is high, the constructed ecological ditch can effectively accumulate water sources to helpthe irrigation of the field and the growing of shrubs, moss plants and aquatic plants, the root systems of the moss plants can be fixed by compact clay, sludge at the bottom of water can be fixed, a natural ecological environment is repaired, and the ecological purifying effect is significant.

Description

technical field [0001] The invention belongs to the field of agricultural environment, and in particular relates to a method for constructing a soil ecological ditch. Background technique [0002] In the construction of modern irrigation districts, the construction of irrigation channel system and drainage channel system is very important. For the purpose of anti-seepage, the ditch system generally adopts a hard bottom. Although it can achieve the purpose of reducing the loss of water delivery in the canal, it loses the ecological function and landscape effect of the ditch water system. Hard-bottomed ditches are usually made of concrete, masonry, soil and other materials, which are reconstructed or newly built on the basis of the original soil ditches in the field. Hard-bottomed ditches have the advantages of durability, low permeability, and high irrigation rate, which can reduce the spread of weeds and seeds on field ridges; earthy. In addition, traditional drainage dit...
