| 摘 要： | 滴灌条件下对枣树进行生育期长势与产量监测,通过对枣树基径、树高、梢条和叶片在年生长周期及各时期的动态变化进行初步分析,结果表明枣树年生长周期在4月至11月之间,在年生长周期内枣树枝干生理生长在夏季最快,基径、树高、梢粗和梢长的增长量最大;枣树叶片的生理生长在春季最快,叶片厚度、叶绿素含量及叶面积指数增长量也最大;5年生灰枣果实的平均产量为9 316.2kg/hm2,果实中含有较高的还原糖、维生素C和人体必需的微量元素Ca、Mg、Fe。

| Abstract: | The growth and yield of Zizyphus Jujube in growth period under drip irrigation are monitored and the dynamic variation of basal diameter,tree height,shoot and leaf in the annual growth cycle of jujube tree is analyzed.The results show that the annual growth cycle of jujube tree is between April and November,the physiology growth of branches is the fastest in summer in the annual growth cycle of jujube tree,the growth of basal diameter,tree height,shoot diameter and shoot length are the largest.The physiological growth of leaves is the fastest in spring,the growth of leaf thickness,Chl content and LAI are the largest too.The average fruit yield of 5-year jujube tree is 9 316.20 kg/ha,and the contents of revertose,vitamin C and essential trace elements Ca,Mg,Fe in fruit of Zizyphus Jujube are very high. |
