In this dissertation, 4 models of integrated water conservation and planting patterns were studied in field experiments, and their mechanisms of yield improvement and WUE enhancement were discussed by testing soil and crop characters.

本文重点研究了旱地高效用水技术中四种保水与种植一体化模式,通过大量田间试验,和相关土壤过程与作物生长、生产指标的测定,分析了四种保水与种植一体化模式的增产与提高农田水分生产效率(WUE)的机制。

In a ward,irrigation under mulch could improve soil water content and WUE,and drip irrigation under mulch was a suitable water-saving and water conservation pattern for Weibei apple orchard,which could not only save water,but also maintain higher soil water content.

总之,覆膜能提高土壤含水率和水分利用效率,膜下滴灌在节水的条件下,还保持了最高的土壤含水率和土壤储水量,适合在渭北黄土高原果园节水灌溉中应用。

In recent years, with the rapid development of information technology and extensive application, with the development and reform of water conservation, the work of the Water Affair Automation also been fruitful, and gradually become an important support water activities.

近年来,随着信息技术的迅猛发展和广泛应用,伴随着水利事业的发展和改革,基层管理站的水务工作的办公自动化也需要进一步推广深化。

The index system of regional water conservation is set up to reveal relationships between elements in this system and subsystem.

建立了区域节水指标体系，以反映各子系统内各要素以及子系统间的相互关系。

Water conservation volume been affected by aspect and slope factors.
