在盐碱地上建植草坪,不仅能美化环境,保持生态平衡,还可以减少地表蒸发,抑制土壤返盐。但是,在盐碱地上建草坪,需采取一些特殊的措施,才能保证草坪的建植成功及长期使用。 盐碱地的改良 由于盐碱地土壤含盐量高,土壤结构差,对草坪草的生长极为不利,在建植草坪前必须进行土壤改良。改良的方法主要有:排涝除盐法,即通过排除积水、降低地下水位,达到排涝除盐的目的;洗盐法,即利用淡水 In saline-alkali soil to build lawns, not only can beautify the environment, maintain ecological balance, but also reduce surface evaporation, inhibit soil salt return. However, to build turf on saline-alkali soil, some special measures need to be taken to ensure the success and long-term use of the turf. Saline-alkali soil improvement Saline-alkali soil salt content is high, the soil structure is poor, the growth of turfgrass is extremely unfavorable, before planting the lawn must be soil improvement. Improved methods are: drainage water and salt removal method, that is, by excluding water, reduce the water table to achieve drainage and desalination purposes; salt washing method, that is, the use of fresh water
