摘要
在土壤－植物－大气连续体系（ＳＰＡＣ）中，以植物茎、果微增长及其含水量变化作为植物需水信息建立的灌溉自动控制系统，可实现植物水分适度亏缺，有效调控其生长发育。实验结果表明，同充分供水的植株或树体相比，节水１５．６％时，玉米长势良好，节水２１．４％时，柑桔果实生长未受影响。
In Soil-Plant-Atmosphere Continuum an automated irrigation control system, based on the microgrowth and water content change of plant Stem and fruit as water-requiring information, can maintain green plants a proper water deficit and adjust their microgrowth effectively. Experiment showed that, compared with the plants well irrigated, corn and orange fruit grew well when the decrease of irrigated water reached 15.6% and 21.4%, respectively.The study supported by Fund qualified Majors to Authorized Ph. D. Degrees at Colleges.
