| Abstract: |
| 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. |
