摘要
采用改进的离体连续快速称重法对无芒雀麦、紫花苜蓿、冰草整株以及叶片蒸腾速率、蒸腾量进行测定。结果表明,冰草的枝蒸腾速率和叶片蒸腾速率均最高,其次为紫花苜蓿,无芒雀麦最低;在7~9月中,3种牧草在8月份整株和叶片的平均日蒸腾量均最高,9月次之,7月最低。
The transpiration rate and transpiration quantity of whole plants and leaves of Bromus innermis, Medicago sativa and Agropyron cristatum are measured by using improved quick and continuous weighting after being cut off method (QCWC). The results show that transpiration rate of branch and leaves of Agropyron cristatum is highest in 3 forages, Medicago sativa is second Bromus innermis is lowest. During July to September, the average daily transpiration quantity of whole plants and leaves of 3 forages is highest in August, September is second and July is lowest.
