摘要
在葡萄果实膨大期喷施"FA旱地龙"与"旱露植宝"2种抗蒸腾剂,研究其对葡萄的生理调节作用及节水抗旱效应。结果表明:喷施抗蒸腾剂可以提高光合速率、减低气孔导度、降低叶片蒸腾强度,起到促进葡萄生长和减少水分散失的作用;同时还可以提高葡萄叶绿素含量和叶片含水量,有利于减轻干旱胁迫。喷施抗旱蒸腾剂对葡萄具有增产作用,增产幅度为7.2%。抗旱蒸腾剂的有效期一般在9 d左右。
The research was about the spraying effects of two anti-transpirants named FA Handilong and Hanluzhibao during fruit swelling period to investigate the physiological regulation and anti-drought and water saving effects on grapes.The results showed that anti-transpirants spraying could increase photosynthetic ratio,decreased stomatal conductance,lower transpiration intensity,thus promoting the growth of grapes and decreasing the loss of water in the plants.On the other hand,it could increase chlorophyll content and water content in leaves,which was helpful to allievate drought stress.The use of two agents at the same time could boost production by as much as 7.2% and its effect could last as long 9 days.
