摘要
通过对抗旱指数(DRI)的分析和改进,首次提出了水分适宜指数(WAI),并以此为指标,在不同的水分条件下对18个不同的玉米品种进行抗旱性研究。结果表明:WAI可以更好的反映不同水分条件下的产量变化,并且倾向于选择高产型品种。可以作为作物适水种植的筛选方法。
Water adaptive index of different moisture（WAI） was put forward firstly in this study by analyzing and improving on Index of drought resisting（DRI）. Drought resistance of eighteen maize varieties was conducted in different soil water conditions by using this index. The results showe that WAI can reflect the variety of grain yield better in different soil water conditions and tend to choose the varieties of high grain yield. WAI could be used as a filtrating method appraising water adaptive plant of crop varieties.
