| 摘 要： | 研究了江苏省沿海地区覆盖与种植对轻度盐渍化土的水分、盐分、温度、养分等生态环境以及覆盖对大麦生长发育和产量的影响。结果表明：春旱季节，覆盖可以减少土壤水分蒸发，抑制盐分表聚，降低土壤溶液浓度和土表温度，增加土壤有效养分，种大麦后由于植株的蒸腾作用，使土壤水分降低，但土壤盐分和溶液浓度仍低于裸地。盆栽试验结果还显示，覆盖种麦有效地促进了大麦生长发育，显著地提高了大麦产量。

| Abstract: | The effects of covering and planting on soil eco-environment,such as water,salt,nutrition and temperature,andon barley growth and yield were studied in the coastal area ofJiangsu. The results showed that in the dry spring,the mulchcould reduce soil water evaporation,restrain soil saltaccumulation.lower soil solution concentration and too soiltemperature,and increase soil available nutrition. The crop plant-ing could reduce soil water due to barley transpiration,but soilsalt and solution concetration were still lower than those withoutcrop. The pot-culture experiment results also showed that themulch effectively promoted barley growth and significantly raisedbarley yield. |
