摘要
以太阳辐射、气温为驱动变量,建立了棉花生长发育与形态发生及产量形成的动态模拟模型(CGSM)。模型通过太阳辐射能利用率的变化,逐日模拟出棉田当日生产的净生物量,并分配到各个器官分别生长,从而可得到各所需时间的单位面积总干重、茎枝总重、总叶重、蕾花铃总重和叶面积系数等;根据棉花生长所经历的温度,可模拟株高、主茎叶数、果枝数、果节和蕾铃发生与分布并可在计算机上显示出生长期内任意时刻的彩色棉株图。经检验证明,本模型基本上能较准确地模拟高产棉花的生长发育动态,可在一定的程度上为生产管理决策提供参考。
Based on researches of cotton cultivation and its ecophysiology for several years, a simula- tion model of cotton growth and development and yield composition (CGSM) has been estab- lished under the special Chinese conditions. Solar radiation and mean temperature of each day were used as driving variates in establishing the relation structure in CGSM, based on eco- physiological process, radiation energy use, partition of dry matter, morphogenesis, produc- tion and development of squares and bolls and yield composition. The CGSM model could be used to simulate dynamic process of cotton growth and development and yield composition in different radiation and temperature conditions when water and fertilizer were available. Cotton plant height, numbers of stem leaves, numbers of branches, squaring, flowering, boll setting, boll-opening and their distribution. The total plant weight, weight of root, stem and branch, leaf weight, reproductive organs weight per unit area and leaf area index (LAI) are included. And colour cotton plant map and statistic tables of numbers of squares, flowers, ab- scissions, bolls, and open bolls can be shown on screen.
