摘要
在籽藕生长期,以浓度为100mg/L、150mg/L和200mg/L的S3307水溶液喷施籽藕叶面,可明显提高籽藕叶片叶绿素含量、光合速率(Pn)、气孔导度(Gs)、蒸腾速率(Tr)、细胞间CO2浓度(Ci)及产量,其中以150mg/L的S3307增产效果最好。
In the growing season of lotus root,the leaves of lotus root with aqueous solution of S3307 had been sprayed as the concentration of 100mg/L, 150mg/L, 200mg/L. It markedly improved the contents ofchlorophyll, photosynthetic rate(Pn), stomatal conductance(Gs), transpiration rate(Tr ) and intercellular CO2 (Ci) ,it has the best effects of increase production by spraying S3307 as 150mg/L.
