摘　　要：在 4年试验秋芝麻产量与夏芝麻高产水平基本一致的基础上 ,用江汉平原腹地—荆州地区的长期气象资料 ,对秋芝麻和夏芝麻各生育阶段的温、光、水条件进行适应性分析 ,结果表明 :秋芝麻各生育阶段对温、光、水条件的要求与江汉平原的气候资料吻合度总体上比夏芝麻高 ,尤其是降水状况对秋芝麻较为有利。而温、光条件对秋芝麻稍有不利之处 ,可以用适当的栽培措施弥补。在夏芝麻主产区—江汉平原适度发展秋芝麻 。A experiment was conducted in four years, the results showed that the yield of autumn-sesame (AS) was almost the same to the high-yield level of summer-sesame (SS). To analyse the temperature, illumination and water conditions of per growing-period of AS and SS with the long-term climatic data of Jingzhou area, which was the hinterland of Jianghan Plain, showed that AS's demanded conditions of temperature, illumination and water per growing-period was closer to the nature climatic resource to Jianghan Plain than SS's on the whole, especially water condition. A little harmful climatic condition to AS could be remedied with suitable cultivated methods. To develop AS in moderate degree in Jinghan Plain where was the main productive area of SS was on the reliable climatic and ecological base.
