In order to investigate the effects of plastic mulch on soil temperature and water consumption of winter wheat on dryland, a field experiment was carried out . Results indicated that plastic mulch and manure increased soil temperature obviously at early growth stage and the effect only appeared on soil surface obviously at latter growth stage. Single plastic mulch had better effect in increasing soil temperature and was more previous compared with single manure at early growth stage, while single manure had higher temperature than single plastic mulch at latter growth stage. Plastic mulch and manure improved not only water consumption of wheat significantly through increasing water consumption from jointing to anthesis, but also yield and the WUE. Single plastic mulch had better effects in increasing soil temperat ure, saving water, and increasing yield and the WU E compared with single manure.Mixture of manure and plastic mulch reduced the effect in increasing soil temperat ure by plastic mulch at early growth stage and improved the effects at latter growth stage, reduced water consumption at seedling stage, and improved water consumption of mulch-covered wheat (3. 5 %) weakly, while yield and the WUE were increased sharply by 10. 6 % and 7. 6 %, respectively. By the influences of manure applied on soil temperature and water consumption of mulch-covered wheat, manure can regulate exuberant growth of mulch-covered wheat before winter, but promote mulch-covered wheat’s senescence during maturity stage.
