Abstract: In order to screen the suitable parameters of ebb and flow irrigation for tomato seedlings, the L9 (33) orthogonal experimental was designed using tomato variety Ouxiu201. The growth and physiological changes and the irrigation index of tomato were analyzed under the top sprinkling irrigation and ebb and flow irrigation. The results showed that compared with the top sprinkling irrigation, ebb and flow irrigation could save water 34.1%-77.0%. Irrigation height was the most important factor affecting the growth of upper tomato plants and water consumption, while dipping time played a major role in the growth of underground part of tomato plants, and the irrigation frequency was the major role affecting photosynthetic physiology of tomato, under the 3 treatment factors set in the test. In summary, the irrigation height of 2.0 cm, dipping time of 1.5 h, the irrigation frequency of once every 3 days combination can be used as appropriate parameters of the tomato ebb and flow irrigation.

Key words: ebb and flow irrigation, tomato, water consumption
