摘要
了解作物在地上和地下与水分的相互作用对于研究间作系统的性能是很重要的。该文对近年来国内外对间作系统内水分在作物间的分配与利用的研究成果作了简单的综述,包括水分在间作作物间的分配、间作条件下作物需水量的估算模型和间作条件下的根系吸水模型。指出了此项研究存在的问题,进而对其今后研究方向和发展趋势进行了展望。
A knowledge of plant interactions above and below ground with respect to water is essential to understand the performance of intercroping systems. The progress of water partitioning and use in intercropping systems was summarized, which included the water partitioning in intercrops, the crop water requirement models for intercropping systems, and the root water uptake model in intercropping systems. The problems of studies in this field were also point out. Furthermore, the trend of research and development in the future was prospected.
