摘要
在花木幼苗的扦插繁殖中,弥雾系统一直采用平板式电子叶传感器,使基面水分的蒸发常常滞后于实际叶面,严重影响了插穗的水分平衡。现用曲面基板代替平板。理论分析和试验结果表明,优选出的适合弥雾扦插的电子叶基面直径为30 mm,电极间距为2～4 cm,可满足不同插穗对水分的需要。
Mist system has been widely used in cutting propagation.Electronic-leaf(EL) is a sensor to control the work of mist system.Traditionally,the structure of the EL is flate. From practice,it is found that the flate EL conducts information often behind the real situa- tion because it collects more water than real curved leaves.In order to simulate the real wa ter situation on the cutting leaves,curved surface structure of electronic leaf is needed.The optimal shapes of the curved surface for the various weather condition are answered from theory and experiments.
