Method for planting herbaceous plant in furrow-shaped out-soil in saline and alkaline land

Abstract

The invention relates to a method for planting herbaceous plants in furrow-shaped out-soil in a saline and alkaline land. The method comprises the following steps: digging multiple furrows in parallel in the saline and alkaline land, and sequentially filling a pebble bed and an aeolian sand layer into each furrow; on the aeolian sand layer, placing two or more rows of support stone in parallel in a direction extending along with the furrows, and forming a planting area between every two adjacent rows of the support stone; mixing the aeolian sand with herbaceous plant seeds, and uniformly throwing the seeds into the planting areas; by taking the support stone as a support, covering the planting areas with plant fiber gridding cloth, wherein meshes through which plant seedlings penetrate are densely formed in the plant fiber gridding cloth; and placing a drip irrigation pipe above the plant fiber gridding cloth, and irrigating the planting areas at regular time. By adopting the method provided by the invention, technical difficulties in planting grass in the furrow-shaped out-soil in the saline and alkaline land can be solved, salt dust leaching and soil wind erosion can be prevented and treated, effective evaporation of a surface layer can be reduced, a soil environment can be improved, the seedling survival rate can be increased, and popularization values can be made.

Description

technical field [0001] The invention relates to the technical field of saline-alkali soil control and ecological construction, and in particular to a method for planting herbaceous plants with ditch-shaped guest soil on saline-alkali land. Background technique [0002] There are large areas of severe saline-alkaline desert salt crust, or severe saline-alkali sandy land in China. In recent years, due to the demand for resource development, ecological construction should be carried out in saline-alkali wasteland to restore local vegetation and rebuild ecological green space. However, the original salt crust is hard, with a salt content of more than 60%, so it is impossible to directly plant plants, and it is necessary to rely on foreign soil planting to improve the soil. Due to the environment of drought, strong wind and high salt dust, the herbaceous plants suitable for planting are mainly concentrated on halophytes such as Suaeda salsa and Salicornia. [0003] However, bec...

Problems solved by technology

However, due to the extreme wind and sand in the saline-alkaline wasteland, the plastic film is easily blown away or swept away by the strong wind; and the plastic film cannot be degraded, which easily causes secondary pollution to the environment

In addition, strong solar radiation, strong winds, and desert environments with huge temperature differences between day and night can easily make plastic films weather and become brittle, and often lose their effect within half a year.
