中文摘要: 在考虑土壤水分和降水对冬小麦各生长发育阶段影响不同的基础上,构建了冬小麦水分适宜度计算方法,结合冬小麦温度适宜度和日照适宜度计算模型,建立了冬小麦气候适宜度计算模型。利用不同时段的气候适宜度与冬小麦气象产量的关系,采用加权平均构建了冬小麦播种至某一发育阶段的气候适宜指数。利用历史气候适宜指数最大值、平均值、最小值和冬小麦观测试验资料,建立了冬小麦播种至某一发育阶段的气候适宜程度诊断阈值;并利用该阈值,建立了冀、鲁、豫地区冬小麦播种至某一发育阶段的气候适宜、基本适宜和不太适宜诊断指标,对提升农业气象定量评价服务具有十分重要的意义。
Abstract:Considering the different effects of soil moisture and precipitation on winter wheat in different growth stages, the calculation method for winter wheat moisture suitability is established in this paper. Then the paper further constructs a climate suitability model of winter wheat combining the calculation models of winter wheat temperature suitability and sunshine suitability. Using the correlations between climatic suitability under different periods and meteorological yields of winter wheat, climate suitable index of winter wheat from sowing to some time in the growing period is established by weighted average. Making use of historical maximum, minimum and average climate suitable index and the observed test data of winter wheat, the diagnostic threshold of climate suitable grade from winter wheat sowing to a growth stage is set up, and then based on this diagnostic threshold, three diagnostic indicators of climate suitable grade in Hebei, Shandong and Henan Provinces are built. The results are significant for improving the quantitative evaluation of agrometeorological service
