中文摘要: 依据于物质积累的基本规律,用包括早、中、晚熟和紧凑、平展两类株型的10个玉米杂交种在北京、延庆、泰安、公主岭、石河子5个不同气候类型地区的试验观察数据,模拟出玉米的标准生长函数W=[1+e8.56-13.52μ)<.sup>]-1。据此建立潜在生物量与品种所需积温的关系:Bmax/kg·亩-1=100+1.1∑Tm。用此模式估算了不同熟性品种的潜在产量,讨论了模拟结果在气候变化影响评价中的应用。
Abstract:In year, The observation of 10 sorts of corn hybrids with different maturing dates called early, medium and late corns and with their different leaf angles such as erectophile and planophile have been taken in Beijing, Yanqing County (Beijing area), Taian (Shandong Province) , GongZhuling (Jilin Province) and Shihezi(Xinjiang Aitononous Region), Based on the data obtained from the observations,a normal growing function was derived on the princplie laws of th accumulated dry matterW=[1+e8.56-13.52μ)<.sup>]-1In accordance with the function, the authors built up a model of the potentiol maximum biomass dependent on the accumulated temperature. Bmax/kg·-1=100+1.1∑Tm. The model was applied to estimate the potential corn yield of the hybrids different maturing and the results in assessing the impact of climatic change are discussed.
