中文摘要	在西北半干旱雨养条件下,采取3种地膜覆盖方式,研究了冬小麦地膜覆盖的水分效应.结果表明:覆膜可显著提高土壤表层（020 cm）墒情,越冬前至返青期覆膜处理的土壤表层含水量较露地处理（CK）高2.8%6.4%,但拔节后覆膜处理的土层表墒与露地处理相近,而20 cm以下深层墒情则表现为覆膜处理逐渐低于露地处理;拔节至成熟期露地处理20200 cm土壤平均含水量高于覆膜处理2.0%.3种覆膜方式比较,0200 cm土体全生育期平均含水量以甘谷模式最高,甘肃模式最低,覆膜处理间的差异远小于覆膜与露地处理间的差异.虽然覆膜的高产建立在高耗水基础上,但通过休闲期水分补充,地膜茬0200 cm土体水分在冬小麦播前可完全恢复到露地水平.
英文摘要	The effects of plastic film mulching with three methods on soil moisture content in winter wheat field were investigated under semi-arid rained conditions in the Northwest of China.The results showed that the plastic film mulching could significantly increase the moisture content of soil surface layer（020 cm）,the soil moisture under the treatment of mulching on soil surface layer from the initial stage of wintering to the turning-green stage was 2.8 %6.4 % higher than that of the open field.However,after jointing stage,the moisture of soil surface layer was similar among mulching and the open field treatments,the deep soil（below 20 cm）moisture of mulching was gradually lower than that of open field.From jointing to mature stage,the average moisture of open field in 20200 cm soil layer was 2.0 % higher than that of the mulching.Compared with the average soil moisture of whole growth period in 0200 cm under three mulching treatments,Gangu pattern was the highest,Gansu pattern was the lowest,the differences between mulching treatments were significantly smaller than those between mulching treatments and open field contrast.In spite of the high grain yield of film mulching was based on high water consumption,the soil moisture of film mulching stubble field in 0200 cm could be fully restored to the level of the open field before autumn seeding by water compensation of fallow period.
