对朝阳地区常见的3个品种枣苗2年生嫁接苗进行4个不同土壤控水处理，设置4个土壤水分处理梯度，研究3个枣苗品种在不同水分胁迫条件下，随着胁迫时间延长，其叶水势的变化规律。结果表明,三星大枣相比其他2个枣品种抗旱性更强。对3种枣苗耗水量情况的初步研究得出，3种枣苗耗水量最大值均出现在8月中下旬，其中三星大枣耗水量高于其它2个枣苗品种。%Of jujube seedling, 2 years old were four different soil water control in Chaoyang area of three varieties, set four soil moisture treatments. The changes of leaf water potential of three Jujube Cultivars under different water stress conditions were studied. Only from the analysis of leaf water potential index, the result shomed that the other two varieties of Chinese jujube jujube stronger drought resistance. At the same time on the three kinds of jujube seedling consumption volume conducted a preliminary study, we can conclude three kinds of jujube seedling water consumption is the biggest value appeared at about 8 months late, which Samsung jujube water consumption is higher than the other two jujube seedling varieties it can about and.
