| 摘 要： | 比较大垄双行覆膜处理和行间覆膜处理环境因子和生理指标,得出大垄双行覆膜处理更有效地改善玉米作物的生长环境,增加土壤温度,抑制棵间蒸发,提高土壤含水量,使地表20cm土层在长期无降水补给时仍能维持较高的含水量,利于玉米生长.在生育期内大垄双行覆膜处理的叶面积指数均高于行间覆膜处理.

| Abstract: | Comparing the environmental factors and physiological index of film-mulching of double-line width ridge treatment with covering film between furrows it can conclude that film-mulching of double-line width ridge treatment effectively improves growing environment of maize,increases soil temperature,inhibits soil evaporation and improves soil water content.It can make the top soil in 20cm maintain relatively high water content with no precipitation supplied in a long term and is advantageous to the growth of maize.The LAI of film-mulching of double-line width ridge treatment is higher than covering film between furrows treatment during the whole growth period. |
