本文提出的“水稻钟”模型是一种适合于计算机应用的动态模拟模型。它由水稻生育期模型和叶龄模型组成。生育期模型用来模拟逐日温度和日长对水稻发育的影响,它具有较高的精度和良好的解释能力,其参数可反应不同类型水稻品种的基本营养性、感温性和感光性。叶龄模型则用来模拟逐日温度对叶龄发育的影响,它可以预测不同叶位的出现日。由于叶龄和分蘖、茎、根、穗等形态学器官存在着较好的同伸关系,因此叶龄模型亦可用来模拟器官形成的时间。生育期模型和叶龄模型还可以相衔接,用来估计任意地点和年份的总叶龄。最后作者利用长江流域14个点(1985)和8个点(1986)的试验资料对上述模型进行了检验与评价.
The “rice bell” model proposed in this paper is a dynamic simulation model suitable for computer applications. It consists of rice growth model and leaf age model. The growth period model is used to simulate the effects of daily temperature and daily growth on rice development. It has high precision and good explanatory power, and its parameters can reflect the basic nutrition, temperature sensitivity and photosensitivity of different types of rice varieties. The leaf age model is then used to simulate the effect of daily temperature on leaf age development, which can predict the appearance of different leaf positions. Leaf ages are also used to simulate the time of organ formation, because of the well-defined relationship between leaf age and tillers, stems, roots, ear and other morphological organs. The growth model and leaf age model can also be linked to estimate the total leaf age at any location and year. Finally, the author tests and evaluates the above models by using the experimental data of 14 points (1985) and 8 points (1986) of the Yangtze River Basin.
