喷施抗旱剂对小麦抗旱增产的研究

Research on the Effectiveness of Drought_resistant Agent to Drought Resistance and Output in Wheat

小麦生育中后期叶面喷施化学调控物质 (抗旱剂 ) ,对蒸腾速率、保水力、干重含水量、外渗电导率和叶绿素含量等均有不同程度的影响 ,明显地改善了小麦的水分状况 ,降低了电解质的外渗率 ,有明显的保绿延缓衰老的作用 。

Spraying chemical controlling matter(drought_resistant agent)on wheat blade in medium_late growth period We found it influenced transpiration rate,water_retaining capacity,containing water content of dry weight,seeping conductive rate,chlorphyll content and so on in different degree,and improved the moisture content stage of wheat,reduced the seeping of electrolyte,have an obvious effect on delaying decrepit and increasing production .
