１９９７～１９９８ 年在山西临汾就地膜穴播小麦集水有限补灌技术进行了研究。结果表明，地膜穴播条件下，不同时期、不同补灌量的小麦产量存在显著差异。拔节、扬花期每公顷各补灌３００ ｍ ３＞ 拔节期每公顷补灌３００ ｍ ３＞ 拔节和扬花期每公顷各补灌１５０ ｍ ３＞ 扬花期每公顷补灌 ３００ ｍ ３＞ 拔节期每公顷补灌１５０ ｍ ３＞ 扬花期补灌１５０ ｍ ３＞ ＣＫ（未补灌）。表明地膜穴播小麦和露地条播小麦相同，水分补给是其提高单产的重要突破口。
From 1997 to 1998, we studied the limited irrigation technology of film mulching wheat in catchment at Linfen, Shanxi Province. The results showed that there were significant differences in the yield of wheat under different conditions of plastic film mulching. Jointing and flowering stage 300 m 3 of supplementary irrigation per hectare> 300 m 3 of supplementary irrigation per hectare at jointing stage> 150 m 3 of supplementary irrigation per hectare at jointing and flowering stage> 300 m 3 of supplementary irrigation per hectare during flowering stage> Replenishment irrigation 150 m 3> Flowering irrigation 150 m 3> CK (without filling). It shows that the mulching of mulched wheat is the same as that of open-field mulching wheat, and the moisture supply is an important breakthrough point for raising yield.
