在西澳大利亚州西南部的农业区中，约60%的土地上都有双重或质地对比的土壤。一年生的小麦、大麦、燕麦和羽扇豆作物在这些土壤上占主导地位，与一年生牧场轮流种植。气候的特点是凉爽，潮湿的冬天和炎热，干燥的夏天。作物生产仅限于冬季和春季，并受到冬季多雨月份内涝和春季灌浆期缺水的限制。在过去的8年里，联邦科学与工业研究组织旱地作物和旱地作物方案和西澳大利亚农业部的一个合作小组一直在对双重土壤上的作物生产进行研究。这项研究集中在3个地点，在这些地点，双重土壤上限制作物生产的过程得到了强调。这期特刊是为了总结这项研究，并从区域和国家的角度加以介绍。此外，还借此机会比较和对比了西澳大利亚州和整个澳大利亚的经验，并提出了双重土壤作物生产的管理方案。
Duplex or texture-contrast soils occur over about 60% of the agricultural areas of south-west Western Australia. Annual crops of wheat, barley, oats, and lupins predominate on these soils, grown in rotation with annual pastures. The climate is characterised by cool, wet winters and hot, dry summers. Crop production is restricted to the winter and spring and is limited by waterlogging in the wet winter months and by water shortage during grain filling in spring. Research on crop production on duplex soils has been undertaken for the past 8 years by a collaborative team from the CSIRO Dryland Crops andyoils Program and the Western Australian Department of Agriculture. This research has been focussed on 3 sites at which processes limiting crop production on duplex soils have been highlighted. This special issue was initiated to summarise that research and to put it in its regional and national perspective. Additionally, opportunity was taken to compare and contrast experiences both within Western Australia and throughout Australia, and to draw out management options for crop production on duplex soils.
