盆栽试验的结果表明，在非种植条件下，盖草量与土壤水分蒸发量；表土盐分含量与覆草量之间均呈极显著线性负相关。在种植大麦条件下亦遵循上述规律，盖草比不盖草减少水分蒸散量９７．３ｍｍ，效果十分明显，１７次测定各处理５ｃｍ处土壤溶液电导率与水分蒸散量之间均呈极显著线性正相关，水分蒸失越多，盐分浓度越高。覆盖节水抑盐效果明显，盖草比不盖草的大麦生育性状和产量均有所提高 The results of pot experiment showed that there was a significant linear negative correlation between topsoil salinity and topsoil under non-planting conditions, cover grass and soil water evaporation. Under the conditions of growing barley also follow the above rules, cover grass than non-cover grass to reduce the evaporation of water 97.3mm, the effect is very clear, 17 times measured at 5cm soil solution conductivity and water evaporation were extremely significant linear between Positive correlation, the more water loss, the higher the salt concentration. Water-saving and salt-tolerant were obvious, and the growth traits and yield of barley were higher than those of un-covered barley
