Six treatments were designed according to horizontal distance and vertical depth from sensor to dripper, different upper and lower water content limits were set for differ-ent growth stages, and indexes including tomato growth, root, photosynthetic param-eter, quality, WUE and yield were systematical y analyzed. The result showed that it is suitable to bury soil moisture sensor in sand field with a vertical depth and a horizontal distance both of 10 cm from the dripper.展开更多
