Saline-alkali soil greening method and system

Abstract

The invention relates to the technical field of landscaping engineering, in particular to a saline-alkali soil greening method and system, and aims to overcome the defects that in the prior art, laying of a saline-alkali discharging isolation layer is difficult to apply to large-area saline-alkali soil greening engineering, and the later-period maintenance cost is high. According to the technical scheme, the saline-alkali soil greening method comprises the following steps of acquiring topographic information of a to-be-greened area, and drawing a saline-alkali soil topographic map; partitioning the to-be-greened area and carrying out planting planning on greening vegetation in different terrain areas; according to the plant requirements corresponding to the planting plan, trimming the land, and adding different soil texture improving materials into the soil; erecting a greening irrigation system; planting plants, and starting the greening irrigation system for irrigation; and arranging a soil sampling and monitoring system in the to-be-greened area for monitoring and recording salt content and alkali content data of the soil. The method has the effects that the plant structure in saline-alkali soil greening is optimized, and the later-period maintenance cost of saline-alkali soil greening is reduced.

Description

technical field [0001] The application relates to the technical field of landscaping engineering, in particular to a saline-alkali land greening method and a greening system. Background technique [0002] Saline-alkali land refers to land plots that have a large amount of soil salt accumulation due to differences in geological structure formation conditions, which have a direct impact on planting plants. According to incomplete statistics from UNESCO and FAO, the area of ​​saline-alkali land in the world is 950 million hectares, of which 99.13 million hectares are in my country, and there is a tendency to continue to expand. It is estimated that by 2050, more than 50% of the cultivated land will be saline-alkali The improvement and management of alkalization and saline-alkali land is urgent. The saline-alkali land occupies an important proportion in the composition of our country's precious land resources, and has great potential for development and utilization. It can produ...
