摘要
在柴达木盆地因次生盐渍化而形成的弃耕地上建立稳产、高产的人工草地后,产草量、盖度和可食牧草比例有了明显的提高,降低了土壤含盐量,改善了人工草地样地的微气候,减少了地面的水分蒸发,抑制盐分上移。
Establishment of artificial pasture on arable land abandoned due to secondary salinification in the Chaidamu Basin resulted in stable and high producing pasture. Pasture yield, vegetation coverage, and the proportion of edible forage showed obvious improvements. Also, the soil salt content reduced, the microclimate of the artificial pasture was improved, evaporation from the soil surface reduced, and the upward movement of salt was inhibited.
