| 摘 要： | 抗旱系数在品种的抗旱筛选中有较为广泛的应用。在抗旱系数的基础上加入水分利用效率因子,得到了作物节水耐旱系数(WSDT)。由于考虑了作物耗水量和水分利用效率,WSDT能够表征作物的受旱程度,体现作物对土壤水分的利用能力。利用2007~2008年桓台863计划项目区冬小麦试验资料,对4个小麦品种的抗旱性能进行了评价,并与抗旱系数评价结果进行了比较,WSDT结果更合理,可以在作物抗旱品种筛选中应用。

| Abstract: | Drought resistance coefficient is widely applied on selection of drought tolerant crops.Based on drought resistance coefficient,WUE factor is added and Water-saving and drought tolerance coefficient(WSDT) is produced.Because crop water consumption and WUE are considered,WSDT would be able to characterize drought degree of crops and reflect capability of utilizing soil water.WSDT of four winter wheat varieties were evaluated using experimental data got in 863 project region from 2007 to 2008.The result was c... |
