【摘要】 在水胁迫声发射监测系统建立的基础上,以杨树苗木为对象,研究了杨树苗木茎部声发射信号作为植株需水信息,利用该信息控制电磁阀的开闭来控制灌溉阀门的起停。研究结果表明:应用该系统能够既不影响植株生长,又能达到节水的效果。更多还原

【Abstract】 Water stress in acoustic emission monitoring system established on the basis of a poplar seedlings targeted of poplar seedlings stems. AE signals as plants need water information, use of the information control of the solenoid valve opening and closing valves to control the irrigation cease. The results show: The system can not affect plant growth, while maintaining the water-saving results.更多还原
