| 摘 要： | 以2001、2002两年的试验资料为基础，分析了冬麦田不同层次的土壤水分含量与0～50cm土体水分含量的相关关系，结果表明，10∽20cm根系分布密集层与0～50cm土体水分含量之间关系最为密切，两者间的数量关系为：y=7．62478 0．71324x10-20据此方程可以用根密集层的土壤含水量估测0～50cm土体的水分含量，用于指导小麦的节水灌溉。 |
| 关 键 词： | 冬小麦 根系密集层 计划湿润深度 土体含水量 |

| Abstract: | Based on the experiment data of two years, 2001 and 2002, the correlative relation between the water content of different soil layers and the mean water content of 0-50cm depth soil in winter wheat field is analyzed in this paper. The results shows that the water content of 10-20cm depth soil layer with concentrated root has the closest relation with the mean water content of 0-50 cm depth soil, which can be expressed by the equation: y=7.62478+0.71324x10-20. The equation can be used to estimate the mean water content of 0-50cm depth soil through the water content of soil layer with concentrated root, which will guide the water saving irrigation of winter wheat. |
| Keywords: | winter wheat soil layer with concentrated root water content in planned irrigation depth water saving irrigation |
