精量灌溉中的植物水分精密诊断技术
The precision diagnosis technique of plant water for precise irrigation
【摘要】 针对目前我国水资源短缺的现状,提出基于植物水分诊断检测技术的闭环反馈控制节水灌溉系统.该系统的关键技术是研究可同时精确测量叶片厚度和温度的双参数融合式传感器,厚度测量的传感器原理实验已经完成.
【Abstract】 Aiming at the present condition that water resources run short in our country, this paper puts forward the closed\|loop feedback control system about efficient irrigation based on the detecting technique of plant water content diagnosis. The key technique of the system is to study the double parameter fusion sensor that can precisely measure thickness and temperature of plant leaf simultaneously, the theoretical experiment of the sensor about thickness measurement has been completed.
