中文摘要	为探索生物可降解地膜在河西干旱灌区的增温保水和增产效应,于2014年3-10月在甘肃省黄羊镇甘肃农业大学试验站进行田间试验,研究不同覆盖材料(普通地膜、生物可降解地膜、秸秆和无覆盖)对玉米产量和水分利用效率(WUE)的影响。试验结果表明,普通地膜覆盖和生物可降解地膜覆盖表层土壤温度较无覆盖分别提高1.2℃和0.9℃,秸秆覆盖较无覆盖降低0.4℃;玉米生育期土壤贮水量由高到低依次为普通地膜覆盖、生物可降解地膜覆盖、秸秆覆盖和无覆盖;与无覆盖相比,普通地膜覆盖、生物可降解地膜覆盖和秸秆覆盖玉米净光合速率分别提高32.68%、28.04%和9.33%,玉米籽粒产量分别提高14.84%、13.70%和8.35%,WUE分别提高25.52%、22.26%和13.75%。综上所述,从增温保水、增产和环保方面长远考虑,生物可降解地膜环保无污染,有利于环境和农业生态系统可持续发展,适合在该地区推广应用。
英文摘要	In order to explore the effect of biodegradable film on warming water retention and grain yields of maize in arid oasis irrigation area,a field experiment was conducted to research the effects of different mulching materials ( common plastic film mulching,biodegradable film mulching,straw film mulching and no mulching) on grain yields and water use efficiency of maize in Gansu university set of Hexi oasis irrigation areas during the period from March to October in 2014. The results showed that soil temperature for common plastic film mulching and biodegradable film mulching were 1. 5℃and 0. 7℃ higher than no mulching ,while the low for straw film mulching was 0. 4℃. The order of soil water storage in the growth period of maize from high to low was common plastic film mulching,biodegradable film mulching,straw film mulching and no mulching. Compared with no mulching,the increases of photosynthetic rate for common plastic film mulching,biodegradable film mulching and straw film mulching were 32. 68%,28. 04% and 9. 33%,respectively,increases of maize gain yield were 14. 84%,13. 70% and 8. 35%,respectively,while increases of WUE of maize were 25. 52%,22. 26% and 13. 75%,respectively. In conclusion,taking a long view of warming water retention,yield and environmental protection,biodegradable film was without badly effect on environment and beneficial to agro - ecosystems sustainable development. It was suit for popularizing and utilizing in the region.
