【摘要】 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。更多还原

【Abstract】 Several physiological indexes, after anti-transpirants sprayed over winter wheat,were determined under the artificial dry conditions. Results showed that surface multch-ing can decrease soil water evaporation effectively. Wheat leaves sprayed with fulvic acidand calcium chloride can increase leaf water potential,decrease stomatal conductivity andtranspiration rate. The comprehensive technique of surface mulching,antitranspirats andwater-preservation agents can increase winter wheat yield effectively.更多还原
