Problems solved by technology

These traditional irrigation and drainage engineering technologies have the following objective problems: (1) When the groundwater rises every spring and the surface returns to salt, excessive water resources will be consumed by washing and draining the salt, generally requiring 4500-7500m3/hm The large irrigation quota of 2 leads to high irrigation water consumption, which is not conducive to water saving; (2) The amount of irrigation and drainage projects is large, and the investment in drainage projects is high, generally 0.9-12,000 yuan/hm2 , and the construction of irrigation and drainage projects is cumbersome; (3) Many drainage ditches and a large number of engineering earthworks occupy farmland, which makes the loss of farmland land utilization rate as high as 6%-10%, resulting in waste of cultivated land resources; (4) Maintenance of irrigation and drainage projects The maintenance workload and difficulty are relatively large, especially the maintenance and

Embodiment 1

[0041] Example 1: see figure 1 , figure 2 , image 3 , a method for improving and planting high-quality lawns in heavy saline-alkali land in arid oasis areas, comprising the following steps:

[0042] (1) Excavation of foundation pit: According to the size and shape of the green area, excavate a foundation pit with a depth of 40cm-50cm on the ground;

[0043] (2) Bottom lining film: lay at least one layer of polyethylene plastic film on the bottom of the foundation pit in the step (1);

[0044] (3) Build separation walls around the foundation pit: build concrete retaining brick walls 10cm-20cm above the ground around the foundation pit, and coat at least one layer of waterproof paint on the inner wall of the brick wall;

[0045] (4) Digging drainage ditches and sedimentation pits: set up drainage ditches outside the retaining brick wall, add drainage ditch iron grates above the drainage ditch, and drain water to the sewer; build sedimentation pits near the drainage ditch of...

Abstract

The invention discloses a method for improving seriously saline-alkali land of an oasis area and planting a high-quality lawn, which relates to a soil improving method and the technical field of lawn planting. The method for improving seriously saline-alkali land of the oasis area and planting a high-quality lawn comprises 1 to 18 steps. The method disclosed by the invention has the advantages offast desalination, no salt accumulation in the surface soil, soil fertility improvement, water conservation, high salt absorbing efficiency of plants, and the like.

Description

technical field [0001] The invention discloses a method for improving heavy saline-alkali land in an arid oasis area and a high-quality lawn planting method, and relates to the technical fields of soil improvement methods and green lawn planting. Background technique [0002] In the desert oasis area of ​​Northwest my country, due to factors such as the upward movement of groundwater levels and irrigation methods, there are many salinized lands, forming a large area of ​​heavily saline-alkali land. Especially in recent years, some newly developed industrial parks are often located on heavy saline-alkali wasteland in the suburbs, which makes landscaping work very difficult. In the past, various methods such as alien soil, salt drainage, salt blocking, and biological improvement have been used to improve saline-alkali land to a certain extent. However, most of the planted lawns have low density and coverage, poor lawn formation, high maintenance costs, and the quality of the ...
