摘要
根据油菜生理生态学原理,建立了油菜群体干物质积累和叶面积指数的动态模型,用中油杂2号在武汉地区种植时的试验和当年气象资料对其进行检验,其模拟值和实测值之间的相关系数分别为0.9936(r0.01=0.834)和0.9863(r0.01=0.708),达到极显著水平。
The simulation models were built based on the principles of eco - physiology and the changing laws of dry matter accumulation and leaf area index for winter oilseed rape. They were calibrated by weather data and experiment data of Zhongyouza 2 in Wuhan area, and their correlation coefficients between the simulated and the observed values were 0.9936 （r0.01 = 0.834） and 0.9863 （ r0.01=0.708 ） respectively, both reached significant level.
