水稻生长和产量形成的数值模拟研究

NUMERICAL SIMULATION OF THE GROWTH AND YIELD FORMATION OF RICE

本文提出了水稻的“底物利用函数”H(t),以模拟控制作物体内底物分配的酶系统的功能。根据碳平衡关系和米切利斯-门腾规律,建立了从动力学观点出发的、定量描述水稻营养生长和产量形成与天气条件的关系的数值模拟模式。

In this paper, a substrate utilization function is designed to simu-late the functioning of the enzyme system which manipulates the par-titioning of substrate in rice bodies. According to the carbon balancerule and the Michaelis-Menten law, a group of numerical simulationmodels, which can be used to quantitatively describe the relationshipbetween weather factors and the vegetative growth and yield formationof rice crop, are set up.
