摘　　要：对隰县和太原两个不同生态区的旱地玉米双相覆盖增产特性及生态生理机制的探索表明，双相覆盖玉米均比当地对照增产，增产率隰县为40．64％，太原为14．48％。双相覆盖玉米在隰县比太原叶面积大，于物质积累多，叶片还原糖含量低，叶绿素含量高，光合速率大，灌浆时间长。旱地五米双相覆盖技术在腿县和太原均可推广应用。The effect of aield increasing ynd mechanism of ecology and physiology of maize with two phase mulch on dry land in Taiyuan and Xixian were discussed. The result showed that the yield of maize with two phase mulch were higher than that of local ck respectively. The rate of yield increasing was 40. 64% in Xixian and 14. 48% in Taiyuan. The maize with two phase mulch in Xixian contrasting with Taiyuan have some characters as follows: larger leaf area,more accumulation of dried substance, less leaf reducting sugar, higer choloroplast content, larger photosynthetic rate and longer grain filling duration. The technology of maize with two phase mulch on dry land is suited to be extended application both in Xixian and Taiyuan.
