水分亏缺 water stress
[植] water deficit
- 单施氮、磷肥或氮磷混施在严重水分亏缺时能明显提高春小麦幼苗叶片POD、CAT的活性。
Nitrogen, and phosphorus nutrition can improve the activities of POD and CAT of SWS under severe water stress. - 结果表明:随着水分亏缺程度的加强,春小麦幼苗叶片POD、CAT及ACO活性均表现出“先升后降”的趋势。
The results showed that: under light water stress, the activities of POD, CAT and ACO of SWS increased, and then decreased under severe water stress. - 对半干旱区小麦气候水分亏缺特征进行了系统的研究,建立了小麦气候水分亏缺模型和指标。
The characteristics of climatic water deficit for spring and winter wheats in the region were systematically researched and the climatic water deficit models and indices were established.
