Abstract: To screen the optimum parameters for cucumber seedling with ebb and flow irrigation, Chaomeite cultivar was selected as study material, and orthogonal experimental method (L9) was adopted to explore the growth and physiological characteristics of cucumber seedlings, matrix properties, and irrigation index under either top sprinkling irrigation or ebb and flow irrigation. It was shown that ebb and flow irrigation could save water by 11.6%-79.4% as compared to top sprinkling irrigation. Irrigation height was the key role affecting the growth index and photosynthetic rate of cucumber, while soaking time played a key role in the growth of root, and the irrigation frequency was the most important factor affecting EC and water consumption. To summarize, the combination of 2 cm irrigation height, 1 h soaking time, and 2 d per time irrigation frequency seemed reasonable for cucumber under ebb and flow irrigation.

Key words: ebb and flow irrigation, cucumber, orthogonal experiment, growth, water consumption
