研究结果表明，韭菜单株年生长叶片３１～５２个，每年新叶发生高峰在５～７月份，全年发生新叶间隔的天数平均为８．１天，叶龄全年平均为３８～４１天；叶片生长一年有两次高峰，第１次在５月份，第２次在８月份；叶片生长至最长所需的天数，年平均为１７～１９天。韭菜全年有两次分蘖高峰，第１次在６～７月份，第２次在１０月份，以第１次为主。韭菜叶片数和分蘖数的多少受品种特性、植株生长年限等因素影响。在５～３０℃韭菜的新叶发生数、叶片日生长量与温度呈正相关。新叶发生的间隔天数、叶龄与温度呈负相关
The results showed that the annual number of leaves in Chinese chives increased from 31 to 52, and the annual peak of new leaves occurred in May to July. The average annual number of new leaf intervals was 8.1 days and the annual average leaf age was 38 ~ 41 Day; leaf growth twice a year peak, the first in May, the second in August; leaf growth to the maximum number of days required, with an average of 17 to 19 days. Leek twice a year peak tillering, the first in June to July, the second in October, the first time dominated. The number of leek leaves and tiller number by the characteristics of varieties, plant growth years and other factors. The number of new leaves in chive at 5 ~ 30 ℃, the leaf daily growth and temperature were positively correlated. The number of days between new leaves, leaf age and temperature were negatively correlated
