中文摘要:
      采用盆栽试验，比较深施、浅施、侧施、全施和不施(对照)等保水剂应用方法在充分供水和水分亏缺两种供水条件下，马铃薯（Solanum tuberosum L）生长、产量和水分利用效率(WUE)效应。结果表明,除浅施处理外其它方式施用保水剂处理都能促进马铃薯株高,水分胁迫下能促进马铃薯根系发育。在充分供水和水分胁迫下，深施保水剂使马铃薯产量较对照提高9.4%和16.6%,WUE提高12.82%和54.73%,侧施保水剂使马铃薯产量较对照提高39.4%和21.5%,WUE提高58.79%和59.46%；在水分胁迫下，全施保水剂使马铃薯产量和WUE较对照分别提高15.4%，56.76%。
英文摘要:
      Pot experiment was made to simulate different using methods of Super Absorbent Polymer(SAP), including deep using SAP, shallow using SAP, side part using SAP, all part using SAP and no using SAP(control), to understand the effect on growth and water use efficiency (WUE) of potato （Solanum tuberosum L.） under high and low water condition. The results showed that all SAP treatments enhanced potato plant height, and also accelerated root development under low water condition. Under high and low water conditions, the yields of potato to deep using SAP treatment were 9.4% and 16.6% higher than that of control, and WUE raised 12.82% and 54.73% respectively, and the yields of potato with side part using SAP treatment were 39.4% and 21.5% higher than that of control, and its WUE raised 58.79% and 59.46% respectively. Under low water condition, the yields and WUE of potato with all part using SAP treatment increased 15.4% and 56.76% respectively than that of control.
