| 摘 要： | 本文对春谷品种晋谷10号一生中在株、茎、穗形成过程中的数量观测资料,拟合了相应的数学模型。研究表明:株高、茎高和地上部各茎节间的伸长动态变化规律都符合Logictie生长曲线方程;株重和茎重的增长动态都符合一元四次方程;各茎节间的重量动态变化都遵循一元二次数学方程;穗的伸长动态用普适生长曲线描述更符合实际,穗重增长过程的最佳数学模型是一元四次方程。用数学模型描述作物各器官建成过程中在数量上的动态变化规律,使作物生长发育的基本理论研究步入了动态定量分析阶段,这在作物基础理论研究上是一个新的飞跃,对指导作物生产也有重要的意义。

| Abstract: | Mathematical models were formulated by fitting the data observed during the developmental process of the body, stems and ears of a millet variety, Chin Gu 10. It was found that the dynamic changes in plant height, length of the stems and the elongation of all the stem nodes in the above-ground parts followed the Logictic growth equation. The increase of the plant weight or the stem weight was expressed by a monodic equation of the 4th order. While those of the internodes followed a monodic equation of the 2nd order. Expression of the increase of the ear length by the general growth function is quite similar to the real state. The best model for the ear weight increase is a monodic equation of the 4th order. Modelling the development of the plant organs leads the theoretical research work to a quantitative stage, which will rapidly promote the basic theoretical studies on plant development and crop production. |
