在作物生长过程的电子计算机模拟方面作了一次尝试。建立了计算机模拟所必需的基础软件:将水稻干物质的累积与产量形成分解为几个过程,如 CO_2同化,干物质分配,叶面积扩展,分蘖消长和幼穗分化等,分别制定了数学模型和子程序,并在此基础上建立了水稻群体干物质生产和产量形成的总模型和总程序:进行了水稻群体实验,以确定模型的部分参数。模型的表现在形式上符合实际情况,这说明模型的依据和结构是合理的,但在绝对数量上尚有误差。灵敏度试验提供了关于改变某一参数所产生的影响的信息,这对于指导生产和设计实验有一定的意义。
An attempt was made to computerize the crop growth process. The basic software necessary for computer simulation was established: the accumulation and yield formation of dry matter in rice were decomposed into several processes, such as CO 2 assimilation, dry matter partitioning, leaf area expansion, tillering growth and panicle differentiation, and so on. Mathematical models And subroutines. On the basis of this, a total model and total program of dry matter production and yield formation in rice population were established. Rice population experiments were conducted to determine some parameters of the model. The performance of the model is formally in line with the actual situation, which shows that the basis and structure of the model are reasonable, but there are still some errors in the absolute quantity. Sensitivity testing provides information on the effects of changing a parameter, which is of some significance to guide production and design experiments.
