In order to screen the optimum cell pattern and nutrient solution concentration for cucumber
plug seedling growth under ebb and flow irrigation，this experiment took Cucumber（Cucumis sativus cv．
‘Zhongnong No.18’）as material，and adopted 2 patterns of cell（ regular and abnormal） and 3 nutrient solution
concentrations（×1，×0.5 and ×0.25）to conduct plug seedling growth under ebb and flow irrigation and to test
seedling mineral elements absorption，accumulation，and apparent morphological indicators，etc．The results
showed that along with the gradual increasing of nutrient solution concentration，the amount of mineral elements
absorption and accumulation were gradually increased，that of N，P，K were increased by 102.6%-125.1%．
The chlorophyll synthesis of leaf and seedling plant height，stem diameter，leaf area and fresh and dry weight
of stem and leaves were all increased with the nutrient solution concentration increasing．The effect of normal
plug seedling was better than that of the abnormal one．Thus，the seedling health index was taken as the major
reference index，and an optimal combination，i.e. regular cell pattern plus Hoagland nutrient solution at ×1
concentration level，was obtained．
