| 摘 要： | 通过大田试验覆膜种植夏玉米研究水分利用效率，采用人工打孔取土以及烘干法测定土壤含水量，结果表明：覆膜种植能有效提高作物水分利用效率，夏玉米覆膜种植总需水量较露地减少34．14mm，水分利用效率比露地提高33．31％．作物系数KC值在灌浆期达到最大，其值为1．184．

| Abstract: | A field experiment was conducted in view of crop （summer maize） water use efficiency（WUE） with mulch in this thesis,set out water moisture with the way of manpower-stiletto and soil drier, got and crop （WUE） corresponding crop coefficient （K,） of corresponding plant environment , and got mulch could be good for improving crop WUE：Compared with planting bare-land, the general water requirement of summer maize planting mulch was 34.14mm lower, crop WUE higher than bareland 33.31% ,and the Kc got the top in milky ripening which was1. 184. |
