| 摘 要： | 以高分子材料聚丙烯酰胺(PAM)、秸秆纤维素为试材,系统分析了土壤改良剂扩蓄增容效果。研究结果显示,土壤中施入聚丙烯酰胺对土壤水分蒸发具有明显的抑制作用,一般在施入土壤3 d内就可表现出明显效果;纯秸秆粉碎料和土壤抑蒸剂按一定比例混合施入土壤,在施入土壤6 d后会具有抑制土壤水分蒸发的明显效果,其效果显著高于2种成分的单独施用。 |

| Abstract: | The polyacrylamide（PAM） and the straw stalk cellulose were used as experimental materials in this study through the systematic analyses on the water saving effects of soil conditioners. The addition of polyacrylamide to the soil had obvious suppressing effect on soil water evaporation, and it showed such effect usually in 3 days. The addition of the mixture of straw stalk powder- fragments and the evaporation suppressor based on specific ratio to the soil showed obvious suppressing effect on soil water evaporation in 6 days of treatment and this effect was significantly higher than the addition of either straw stalk powder-fragments or evaporation suppressor individually. |
