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 developed by PenningdeVries was used to simulate the dynamic growth of corn in paddy field with the experimental results of field and sink moisture. Through two years of experimental verification, it shows that the model is consistent with the simulated and measured values ​​of the growth of single crop of corn in the paddy field, the dry matter dynamics of shoot and leaf and the change of the leaf area in the shoot, while the simulation of the intercropping corn is quite different , Further consideration needs to be given to the interaction between wheat / corn during the intergrowth period. The article also made a statistical analysis of the differences between simulated and measured values.
