采用荒漠土壤,以盆栽的方式,探讨了钠复合肥在梭梭、白刺和红砂等荒漠植物生长和抗旱性中的作用。正常浇水11～12周后停止浇水20～22天,与不施肥相比,施用钠复合肥使梭梭同化枝的面积、鲜重、干重和含水量分别显著增加了79%,148%,100%,25%,根的鲜重和干重分别显著增加了63%,45%；使白刺叶的面积、鲜重、干重和含水量分别显著增加了209%,318%,218%,34%,根的鲜重、干重和含水量分别显著增加了217%,138%,43%；使红砂叶的面积、鲜重、干重和含水量分别显著增加了763%,800%,667%,34%,根的鲜重和干重分别显著增加了719%,628%。施用钠复合肥显著增强了干旱胁迫下3种植物的渗透调节能力和活性氧清除能力,从而提高了这些植物的抗旱性并促进了其生长。

The roles of sodium compound fertilizer (SF) in the growth and drought resistance of desert plants Halaxylon ammodendron, Nitraria tangutorum and Reaumuria soongorica were investigated by using pots with desert soils. When water was withheld for 20～22 days after the plants growing under su?cient water supply condition for 11～12 weeks, a comparison with no fertilizer treatment showed that the addition of SF significantly increased the photosynthesizing branch area, fresh weight, dry weight and water content by 79%, 148%, 100%, 25%, respectively, and increased root fresh weight and dry weight by 63% and 45% for H. ammodendron. SF significantly increased leaf area, fresh weight, dry weight and water content by 209%, 318%, 218%, 34%, respectively, and increased root fresh weight, dry weight and water content by 217%, 138%, 43%, respectively, for N. tangutorum. SF significantly increased R. soongorica leaf area, fresh weight, dry weight and water content by 763%, 800%, 667%, 34%, respectively, and increased root fresh weight and dry weight by 719%and 628%for R. soongorica. SF could improve the growth and drought resistance of these plants by enhancing their osmotic adjustment and reactive oxygen species-scavenging capability.
