摘要
运用ＰｅｎｎｉｎｇｄｅＶｒｉｅｓ研制的作物生长模型结合田间与水槽水分实验结果，建立了稻田玉米生长动态模拟模型。通过两年的实验验证，表明模型对稻田单作玉米的生育期、地上部茎叶干物质的动态及叶面积的变化的模拟与实测值较为一致，而对套作玉米的模拟则差异较大，需进一步考虑套作共生期内的麦／玉米之间的相互作用。文中还对模拟与实测值之间的差异进行了统计分析。
The crop growth model MACROS series developed by Penning de Vries was adapted and modified through two years field experiment and soil water controlled plot in 1995￣1996 to construct the CORNMOD. This paper describes the model structure modification and dataset adaption and give the comparison between the simulated and measured results and statistics. The modified model presented the quite reasonable agreement with the actural result for the single cropping corn while the relaycropping corn was found with large deviation value of R and V compared to the measured ones. As for the soil moisture content, simulated and measued dynamics were found to agree quite well in two years during the whole season except for heading stage to maturity of corn in 1995 .
