摘要：
This paper considers the relative merits of various alternative approaches to irrigation scheduling for horticultural crops. In particular, the use of conventional soil moisture monitoring is compared with various approaches based on sensing plant responses to soil moisture deficits. These latter include direct monitoring of plant water status, the morphometric sensing of stem, leaf or fruit dimensions, the sensing of stomatal closure either by porometry or infrared sensing technologies, or the detection of responses such as xylem cavitations. The potential of infrared sensing technologies and strategies for their use are also evaluated.
