| 摘 要： | 为了有效地进行非充分灌溉,通过不同方面研究土壤和作物水分亏缺的诊断方法,从而制定科学有效的灌水指标。对目前非充分灌溉的土壤、灌溉、作物等指标的研究现状及存在的问题进行了的阐述,讨论了非充分灌溉决策指标今后研究发展的方向。从目前国内外研究情况来看,应用叶水势、茎直径变化、冠层温度等作物指标来精确诊断作物的水分状况,已逐渐成为非充分灌溉研究领域关注的热点,但其基础理论、监测方法及不同作物的应用效果仍需进一步研究完善。因此,单纯从一种灌溉决策指标出发确定灌溉量是不全面的,如何建立非充分灌溉条件下不同地区、作物的灌溉指标体系将是今后中国重要的研究内容。

| Abstract: | The diagnosis methods of soil and crop moisture deficit are studied for effective deficit irrigation, which could formulate scientific irrigation index. In this paper, the present situation and main problem of index study on soil, irrigation and crop is illustrated, the research directions in deficit irrigation index are also discussed. According to the international study situation, the technique in diagnosis of crop moisture content condition from the changes of leaf water potential, plant stems diameter and canopy surface temperature etc, has gradually been the hotspots in the field of deficit irrigation, but the basic theory, observation method and application on different crops need to be lucubrated and perfected. Therefore, it is not a comprehensive method to confirm the irrigation capacity by using a single irrigation diagnosis index, and how to found the index system of deficit irrigation of different areas and crops will become an important study in the future. |
