间套作作物水分利用效率的研究综述

Overview of Water Utilization Efficiency of Intercropping Crops

作物间套作是当今农业可持续发展的一个重要举措。特别是在干旱、半干旱地区,在水资源有限情况下,通过间套作作物间的竞争和互补作用,提高农田水分利用效率和产量,是间套作水分利用的一个难点。笔者通过文献综述,系统地分析了间套作水分利用的研究成果,间套作作物的水分利用效率的评估方法,以及研究的难点和发展方向等。分析结果可为实现农业用水高效化及农业的可持续发展提供理论依据。

Intercropping is an important measure for the sustainable development of agriculture, especially in arid and semiarid region and under the condition of limited water resources. To improve water use efficiency and yield by means of the competition and complementary between intercropping crops is a difficult point of water use in intercropping. By literature reviews, the authors systematically analyzed the research achievements of water use efficiency of intercropping crops and its evaluation, and then explored the research difficulties and research priorities. The results could be applied to improving agricultural water use efficiency, and providing a theoretical basis for the sustainable development of agriculture.
