| 摘 要： | 植株茎直径的收缩和膨胀与作物体内水分状况密切相关,茎直径变化测量参数能实时、灵敏地反映作物水分亏缺程度。与其它水分诊断方法相比,基于茎直径微变化监测的方法具有简便、稳定、无损、连续监测和自动记录的优点。通过对作物体内水分的动态监测,并与计算机应用相配合,可以用于温室和大田条件下指导适时灌溉。

| Abstract: | The shrinking and swelling in plant tus within plant, the parameters derived from stem diameter was closely related to the crop water stastem diameter measurements were reliable plant water status indicators, which could reflect crop water deficits sensitively, duly and accurately. Compared with other method, this diagnosis method was characterized for its portability, stability, non- destruction to plant tissue continuous monitoring and automatic logging. The results on crop water monitoring via computer system could be used to guide the irrigation timing under the field and greenhouse conditions. |
