中文摘要:水稻生长和产量形成与外界环境条件之间有着密切关系。本文通过作物光合作用、呼吸作用两个生理过程,把水稻生长与环境条件有机地联系起来,对水稻生长过程进行定量的数学描述。本文探讨了水稻生长过程中干物质的分配规律,建立了水稻器官干物质积累过程、光合作用、呼吸作用、叶面积动态变化等模式。尽管还不够完善,但用它计算模拟水稻生长与产量形成的结果是较为满意的。
 
NUMERICAL MODELLING OF RICE GROWTH AND YIELD FORMATION
Abstract:The growth of rice and its yield formation are closely relatied to the environmental factors. An attempt is made to link the growth of rice organically with its environmental factors through the physiological processes of photosynthesis and respiration so that the growth process may be described quantitatively. The model incorporates the accumulation of dry matter, the dynamic variations, of photosynthesis, respiration and leaf area. Satisfactory results are obtained in the simulation though room for improvement remains.
