초록

This study was conducted to examine the effect of irrigation level on shoot and bulb growth at different growth stages of tulip (Tulipa gesneriana) in sandy loam soil of Imjado, Shinangun, Chonnam. To examine the proper irrigation level, the irrigations of 1, 2, 3, 4, and 5 L･m -2 were treated at sprouting and leaf development stage (March 2013) and at leaf and stem elongation stage (April 2014). And natural precipitation, shoot growth and bulb growth were investigated. At sprouting and leaf development stage in March, leaf length and width of ‘Negrita’ were smaller in 1 L treatment, and bulb growth was worse in 1 and 5 L irrigation. But shoot and bulb growth were good in 2 to 4 L treatments. In ‘Leen van der Mark’, leaf width, circumference and weight of main bulb, and total bulb weight were reduced more in 5 L than the others. Shoot and bulb growth were better in 1～3 L treatments. At leaf and stem elongation stage in April, leaf and bulb growth of ‘Red Shine’ were the best in 2 L treatment. Shoot and bulb growth, such as circumference and weight of main bulb and No. of daughter bulb were reduced more in 5 L treatment than the others. In ‘Kees Nelis’, plant height and leaf length were longer in 2 L, and growth of main bulb was better in 2～3 L treatments. But shoot and bulb growth were worst in 1 and 5 L treatments. Therefore, it was suggested that irrigation of 2 L･m -2 (4 L･m -2 if natural precipitation is included) at the two stages was more effective for water conservation and shoot and bulb growth
