[目的]研究模拟模型技术在冬麦北移中的应用。[方法]在搜集河北省北部9个代表县多年气象资料和布置多点田间试验的基础上,结合小麦的抗寒生理特性,建立其抗寒性模型。[结果]运行模型预测小麦越冬状况,对其结果进行验证,决策出河北省冬麦北移安全北界为北纬41°以南的坝下地区。[结论]为研究小麦生长发育的动态变化规律以及环境、栽培技术对其发育的影响提供了有效工具。
[Objective] The research aimed to study the application of simulation model in the northward shift of winter wheat. [Method] On the basis of collecting the meteorological data of 9 representative counties in northern Hebei Province for many years and arranging multi-point field experiments, combining with the cold resistance physiological characteristics of wheat, the cold resistance model was established. [Result] The operation model predicted the overwintering condition of wheat and verified the result, and decided that the northern part of winter wheat north of Hebei Province should be located in the area below the dam south of 41 ° north latitude. [Conclusion] The study provided an effective tool for studying the dynamic changes of wheat growth and development as well as the impact of environment and cultivation techniques on its development.
