在人为干旱胁迫条件下对冬小麦喷施蒸腾抑制剂后的几项生理指标进行了测定,结果表明:地面覆盖能有效地减少水分蒸发;叶面喷施黄腐酸和二氯化钙能提高小麦叶水势,降低气孔导度和蒸腾强度。覆盖+蒸腾抑制剂+保水剂的综合措施能显著提高作物产量。
Under physiological drought stress conditions, some physiological indexes of transpiration inhibitors of winter wheat were measured. The results showed that: the ground cover can effectively reduce the evaporation of water; foliar application of fulvic acid and calcium chloride can improve wheat Leaf water potential, reduce stomatal conductance and transpiration intensity. The combination of cover + transpiration inhibitor + SAP can significantly increase crop yields.
