摘要 通过对藤本植物爬山虎(Parthenocissus tricuspidata)和廊坊杨(Populus langfangensis W.)分别进行保水剂处理和盆栽控水,研究它们的生理、生态学特性。结果表明:廊坊杨加入保水剂后,随水分胁迫的加剧,其叶水势降低的比较缓慢,原生质膜透性被破坏的也较缓慢,叶水势和土壤含水量关系用指数方程拟合较好;爬山虎的叶水势与电导率成周期性降低趋势,叶水势与含水量用4d移动平均趋势线拟合较好;2种苗木都用小颗粒20g处理的使用效果最好。 An experiment was conducted to study the eco-physiological characteristics of Populus langfangensis and Parthenocissus tricuspidata potted seedlings treated with super absorbent polymers under water stress. Results showed that the leaf water potential (LWP) of Populus langfangensis seedlings treated with super absorbent polymers decreased slowly with water stress lasting, and the relative electrical conductivity (REC) also declined slowly. The relationship between LWP and soil water content (SWC) could be well simulated with exponential equation. The LWP and REC of Parthenocissus tricuspidata seedlings showed a decreasing tendency with a periodicity, and the relationship between LWP and SWC could be simulated by a mean trend line of a four-day change. The effect of super absorbent polymers with small size granule (20 g) is the best.
