摘　　要：旱地玉米采用免耕覆盖技术后，全生育期０～２０ｃｍ土壤温度降低３．１５～２．３４℃；玉米孕穗期延长４～６天；覆盖秸秆造成的“低温效应”对提高作物抗旱能力和形成高产结构是有利的。Compared with conventional tillage, under no-tillage with stalks mulching average soil temperature at 0～20 cm depth decreased 3. 15～2. 34℃ during corn growing period. Booting period prolonged 4～6 days, it is convient to strong drought resistance of crops and promote grain yield

关 键 词：旱地 玉米 免耕 土壤温度
