Non Destructive

The fast non-destructive inspection of plant tubers or roots is a big problem in the plant accurate cultivation. With the characteristic of non-invasion, low cost, no radiation and visualization, the electrical resistance tomography technology is applied to the research of agriculture field; therefore it can be used in the tuber growth status monitoring, new varieties nurturing and fine cultivation of plants. The main research contents include: establish the sensitive model and simulate by using COMSOL software; the affects brought by different positions and sizes of one tuber are studied in detail and the research of effects of tuber number on electrical properties is carried out. The research has crucial guidance for the further study of the TERT technology.

The Relationship

The non-invasion electrical process tomography of plant tuber or root is a new research field in the accurate cultivation of plants. Tuber Electrical Resistance Tomography (TERT) is aimed to extend the application of the technology into agriculture, which can help improving and breeding new varieties of the crops. This paper mainly studies excitation & measurement strategy. Especially the influences on distribution of sensitive field brought by the width and numbers of the array electrodes in the soil environment are analyzed. Besides, the relationship between the electrical conductivity and the measured boundary voltages is also discussed.
