摘要
１９９６年～１９９８年在山西省农科院旱地农业研究中心中试基地，对不同覆膜条件下小麦的耗水特征进行了研究。试验结果表明：旱地小麦采用地膜覆盖能够有效地减少土壤水份蒸发，使植株蒸腾速率增强，地膜穴播和膜侧条播蒸腾速率较对照分别增加０．４８ｍｍｏｌ／（ｍ２·ｓ）和０．７６ｍｍｏｌ／（ｍ２·ｓ），水分利用效率提高了６７．１％和２２．３％，小麦增产幅度为２４．７％和５．３％，具有显著的增产和节水效应。
The
characteristics of water consumption of winter wheat under plastic covering was studied at test
field in Dryland Farming Research Centre of Shanxi Academy of Agricultural Sciences during
1996-1998. The results showed that it could decrease soil evaporation and increase plant
transpiration rate of winter wheat in dryland by plastic covering. The transpiration rate under
filmmulching and bunchseedinf, drilling beside plastic film increased 0.48 and 0.76mmol/(m2s)
than control,while the yiled increased 24.7% and 5.3%, The WUE of wheat raised 67.1% and 22.
3%. they have significant yield increasing and watersaving effects on winter wheat.
