摘要: 本文以黄淮海平原气象数据、土壤理化数据和作物数据为基础,应用WOFOST作物生长模型,估算了黄淮海平原冬小麦、夏玉米的光温生产潜力与气候生产潜力,分析了冬小麦、夏玉米生产潜力年变化率的时空变化规律。结果表明,黄淮海平原近44a冬小麦和夏玉米的光温生产潜力分别为6433.5~10592.67kg·hm-2、7786.17~11185.5kg·hm-2,均值分别为9022.18kg·hm-2、9321.46kg·hm-2,可作为补灌区平均最高产量的上限参考值;气候生产潜力分别为1559.17~6724kg·hm-2、6088.33~9053.17kg·hm-2,〖JP2〗均值分别为4083.24kg·hm.-2、7528.21kg·hm-2,分别占光温生产潜力的45.3%、80.8%,可作为雨养冬小麦与夏玉米平均最高产量的上限参考值。总的来说,冬小麦光温潜力、气候潜力呈现上升趋势,44a分别增加了541.64kg·hm-2、1061.15kg·hm-2;夏玉米光温潜力、气候潜力均呈现下降趋势,分别减少了840.22kg·hm-2、320.59kg·hm-2。〖JP〗本文揭示了黄淮海平原冬小麦与夏玉米的增产潜力及其空间差异,可为改善管理水平、提高作物产量提供数据支持。

Abstract: The WOFOST crop growth model was applied to estimate the potential photo temperature productivity and photo temperate precipitation productivity of winter wheat and summer maize,based on a database containing weather,soil,crop varieties information from Huang Huai hai plain.The production potential of the annual the rate of change of the temporal and spatial variation was analyzed.The results showed that the range of phototemperature productivity of winter wheat and summer maize were 6433.5~10592.67kg·ha-1,7786.17~11185.5kg·ha-1,and the mean was 4083.24kg·ha-1,7528.21kg·ha-1,which can be used as reference value of average maximum yield in irrigated fields.The range of photo temperate precipitation productivity of winter wheat and summer maize were 1559.17~6724kg·ha-1,6088.33~9053.17kg·ha-1,and the mean is 4083.24kg·ha-1,7528.21kg·ha-1,accounting for a photo temperature productivity of 45.3% and 80.8%,respectively,which can be used as the reference value of average maximum yield in rained fieldIn general,for winter wheat,the phototemperature productivity and phototemperatureprecipitation productivity had increased 541.64kg·ha-1,1061.15kg·ha-1,during the past 44 years,while for summer maize,reduced 840.22kg·ha-1,320.59kg·ha-1.Because of the vast plain,the changes of potential productivity were different.By revealing the potential yield and its space difference,this paper could provide support for management improvement and yield increase.
