| 摘 要： | 本文通过对可能影响冬麦生育过程的若干因子的分析，筛选出４个主要气候因子，作为辽宁省种植冬麦的农业气候指标。这４个农业气候指标是：越冬前活动积温为４２０～５４０℃，越冬前降水１２０～１７０ｍｍ，抽穗到成熟期降水 １１０～ １５０ｍｍ，越冬期可耐一 ８００ ℃负积温及一２４～一２６℃的极端最低气温。由此，以农业气候相似论为依据，可以实现以沈阳为中心的辽宁省部分地区冬麦北移种植的构想。

| Abstract: | By analyzing many effect factors during winter wheat growth stages, four main climatic factors were selected, and agricultural climatic indices were established. The four climatic factors are: active accumulated temperature in 420 ~ 540 'C, precipitation in 120 ~ 170mm before wintering, precipitation in 110~ 150mm from heading to ripening stage, and resistant -800 'C accumulated temperature. So based on agricultural climatic theory of similitude, we can effect the plan of planting winter wheat in Liaoning's part area in the center of Shenyang. |
