| 摘 要： | 建立了一个冬小麦光温生产潜力数值模式,该模式可以模拟瞬时光合作用并充分考虑了冬小麦叶片空间分布特征。研究结果表明,北京地区冬小麦光温生产潜力与抽穗前１０天至成熟期辐射量相关性最大,年际之间存在４年和９～１０年的变化周期。黄淮海地区冬小麦光温生产潜力变幅在９０００～１０９５０ｋｇ／ｈｍ２之间,其中河北石家庄地区和山东胶东半岛为两个高值区,超过１０５００ｋｇ／ｈｍ２。模拟结果与当前黄淮海地区冬小麦高产实践结论具有较好的一致性,可为该地区作物高产提供一定的理论指导

| Abstract: | A photo temperature numerical model related to winter wheat producti vity was established, which included development stage,photosynthesis,respirati on,partitio ning of carbohydrate and consenescence of winter wheat.The simulation result of the winter wheat photo temperature productivity in Huang Huai Hai Region by using the model indicated that:(a)The productivity changed from 9 000kg/ha to 1 0 950kg/ha in the region,and the highest value was found in Shijiazhuang Area of Hebei Province and Jiaodong Area of Shandong Province. (b)The winter wheat phot o temperature producti vity was interrelated well with the solar radiation accumulated from 10 days be fore heading to maturity. (c)Analysis of the photo temperature productivity by using the power spectrum found that the change of the productivity in Beijing Area has 4 year and 9-10 year cycles. |
