| 摘 要： | 介绍了水稻干物质模型的研究进展和Chapman-Richards模型的数学结构以及该模型在描述林木生长和不同生物种群生长过程中的应用，并根据国家“863”节水农业专项子课题现场试验资料，用Chapman-Richards模型模拟了水稻干物质积累过程。结果表明。用Chapman-Richards生长方程来模拟控灌水稻干物质积累过程中，Logistic模型拟合效果最好。并根据模型参数对水稻生长过程进行了分析。

| Abstract: | The advance of study on rice dry matter accumulation models, the mathematic structure of Chapman-Richards model, and its application in describing the growth proeess of forest and various biologic populations, were introduced in this paper.Based on the field experimental data, the Chapman-Richards model was used to simulate the rice dry matter accumulation process. The result indicated that the Logistic me, tel had the best simulation result anong the four test models Finally, the rice growth process was analyzed by using the model parame ters. |
