| Abstract: | Aiming at the non-closed loop control problem of the plant water-saving irrigation, according to the direct accurate corresponding relation between the geometry size parameter and its water content of the plant leaf, it is all right to regard this kind of parameter as accurate feedback control variables when the measure precision reaches the grade of microns quantity by using system analysis theory and method. The paper puts forward to a non-destructive high-accuracy detection technique of the plant water content by utilizing physiology of the plant itself to adjust and control the mechanism based on the physics method, and it can realize the intelligent irrigation system that has accuracy closed-loop control and can realize the real water-saving irrigation of the most high-efficient optimization, and develops a micro-displacement sensor with simple structure, high measure precision, well ability to resist environment interfere, and high depend ability. It is significant to abundant water-saving irrigation theory and technology and to form the new products of agriculture. |
