| 摘 要： | 在大白菜生长发育过程中，幼苗叶鲜重的变化可分为前期的增长和后期的衰亡两个阶段。就群体而言，幼苗叶鲜重增长和衰亡的快慢对产量有着显著的影响。这表现在其最大值和衰亡速度方面，幼苗叶鲜重过大或过小、衰亡过快或过慢均不利于高产，其最大重量值在１５３８ｋｇ／６６６．７ｍ２，平均衰亡速度６５ｋｇ／６６６．７ｍ２·ｄ时产量最高。

| Abstract: | The growth of juvanile leaf of Chinese cabbage can be divided into twostages: weight increasing process and weight declining stage.The yield of.Chinese cabbage is remarkable related to the maximum weight and the average decreasing rate ofyoumiao leaf.The results show that the yield of Chinese cabbage is highest when themaximum weight is around 1538kg/667m2 and the average decreasing rate is 65kg/667m2/day. |
