本文依据Monsi群体切片法,研究了青花菜早熟种“绿球”的群体生产结构、群体内光分布特性以及叶片受光姿态诸问题。结果得出:青花菜群体的消光系数K在0.6～0.7之间,多为水平叶排列结构。并对各器官生长的动态关系进行了解析,得到了整个生育期干物营养向各器官的分配规律。 Based on the method of Monsi population slicing, this paper studied the population production structure, light distribution characteristics of the population and the light-receiving attitude of the leaves of early green broccoli variety “Green Globe”. The results showed that the extinction coefficient K of broccoli population was between 0.6 and 0.7, mostly horizontal leaf arrangement structure. The dynamic relationship between the growth of various organs was analyzed, and the distribution of dry matter nutrition to various organs during the whole growth period was obtained.
