| 摘 要： | 在冬小麦的各个生育期，水分胁迫均显著影响小麦矿质营养的吸收、干物质的累积及光合作用等过程，根据时各试验处理麦株个体、群体的生理、生态分析，确立冬小麦各生育期的节水灌溉指标体系。该体系除土壤含水量外，还包括根系湿润层厚度、细胞液浓度、叶水势、蒸腾强度、气孔导度和叶片N、P、K的浓度等指标。

| Abstract: | During growth stages of winter wheat, soil-water stress evidently affects its mineral nutrition uptake, dry matter accumulation, and photosynthesis process etc. According to analysis of physiology and ecology of individual and colony plant of different experiment treatments, winter wheat water-saving irrigation index system is proposed, and in which, not only soil water content, but also depth of root zone, concentration of cell liquid, leaf water potential, transpiration rate, stoma conductance and concentration of N, P, K are included. |
