摘　　要：[目的]确定气候变暖条件下北京地区冬小麦安全越冬的适宜播期。[方法]通过不同品种冬小麦的播期试验(9月25日,10月7日,10月17日),研究正常偏暖气候条件下,冬前积温和小麦叶龄的关系,从苗情角度,为气候变化条件下如何确定播期提供建议。[结果]气候变暖后冬小麦出苗所需积温增加,但随着播期推迟逐渐降低。9月底播种可以实现壮苗,10月中旬播种,冬小麦苗情依然能达到安全越冬的基本要求。[结论]北京地区,冬小麦9月底至10月中旬均可播种。[ Objective] The aim was to confirm on the suitable sowing time of winter wheat varieties from Beijing area overwintering safely. [ Method] Different varieties of winter wheat and 3 sowing dates （09 - 25, 10 -07, 10 - 17） were selected to carry out the sowing time test to study the relationship between the accumulated temperature and the leaf age in normal warm year, and to supply some suggestions for confirm on the sowing date. [ Result ] The result showed that the accumulated temperature for sprout increased with the sowing time delaying. The seedlings sowed in the end of September grew strong, sowed in the middle of October also grew in winter. [ Conclusion ] Winter wheat varieties can be sowed during from the end of September to the middle of October in Beijing.
