| 摘 要： | 比较了不同保水剂使用量下土壤有效贮水量,设置3种土壤水分条件(田间持水量的70%、55%和40%)研究了保水剂对杨树水分利用特征的影响。结果表明,随着保水剂用量的增大,土壤有效贮水量增加;随干旱程度增加,叶片水势和生物量降低。三种土壤水分条件下,随着保水剂用量的增加,灌水量显著减少;同一保水剂用量情况下,中度土壤干旱条件下水分利用效率最大;随着保水剂用量的增加,各干旱条件下水分利用效率相应上升。

| Abstract: | This paper compared available soil water content treated by different super absorbent polymers content,studied the effect of different super absorbent polymers contents on water use characteristics of poplar under three different soil water regimes:adequate soil water,medium drought,and severe drought conditions,which were about 70%,55% and 40% of field capacity.Results showed that available soil water content increased with increased in super absorbent polymers content;with water stress increased,leaf wate... |
