| 摘 要： | 研究了不同秸秆覆盖量下盐渍化土壤蒸发量、不同生育期各土层的含水率及含盐量的动态变化规律.结果表明:秸秆覆盖后,盐渍化土壤蒸发量比对照低,随着秸秆覆盖量的增加,蒸发量逐渐减少,当秸秆覆盖量为0.75 kg/m2(C2)时,日蒸发量减少幅度平缓,趋于稳定.与对照相比,秸秆覆盖量为1.05 kg/m2(C1),0.75 kg...

| Abstract: | The variable law of saline soil evaporation,water content and salt content was studied in the straw mulching condition.The results showed: after straw mulching,the saline soil evaporation is lower than control experiment,with increasing of straw mulching content,soil evaporation is decreased,when straw mulching content is 0.75 kg/m2,the decrease range of day evaporation is changed mildly.Compared with the control experiment,when the straw mulching content is 1.05 kg/m2(C4),0.75 kg/m2(C3),0.45 kg/m2(C2),0.15... |
