Flower bed construction and flower planting method in heavy saline-alkali land in arid area

Abstract

The invention discloses a method for building flower beds and planting flowers and plants in a heavy saline-alkali land in an arid region and relates to the technical fields of soil transformation methods and green lawn planting. The method for building flower beds and planting flowers and plants in the heavy saline-alkali land in the arid region comprises 18 steps and has various advantages of desalting rapidly, achieving long-acting and durable effect, saving water and cost, completely eliminating weeds, promoting growth of ornamental plants and the like.

Description

technical field [0001] The invention discloses a method for constructing a flower bed and planting flowers on heavy saline-alkali land in an arid area, and relates to the technical fields of soil reforming 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. However, the survival rate of the planted ornamental flowers and trees is low, the ornamental quality is poor, and the growth is slow. [0003] Among the various ...

Problems solved by technology

Most of the measures taken are engineering technical measures such as arranging many and deep open channels, underground channels or shaft drainage and irrigation in farmland. These traditional irrigation and drainage engineering technologies objectively have the following problems: (1) When the groundwater rises every spring and the surface returns to salt , Salt washing and drainage consume too much water resources, generally need a large irrigation quota of 4500-7500m3/hm2, high irrigation water consumption, not conducive to water saving; 12,000 yuan/hm2, and the construction of drainage and irrigation works is cumbersome; (3) Many drainage ditches and a large number of engineering earthworks occupy farmland, making the loss rate of farmland land use as high as 6%-10%; (4) The workload and difficul
