The temporal and spatial distribution of SMP in tomato root zone and the correlation between tomato evaportranspiration and SMP variations were analyzed. The results showed that the variation of SMP among the soil profiles of 0, 15 and 30 cm from drip tape was insignificant, and the horizontal distance of tensiometers to drip tape had little effect on the correlation between tomato ETa and SMP variations. Lateral depths significantly influenced SMP from 20 to 70 cm soil layer and there were obvious effects of tensiometer depth on the correlation between tomato ETa and SMP variations.

对番茄根区土壤基质势时空分布和番茄耗水量与土壤基质势变化的相关性分析表明，水平距毛管0、15和30 cm 3个剖面间土壤基质势差异较小，负压计距毛管的水平距离对耗水量与土壤基质势变化的相关程度影响不大；毛管埋深对20～70 cm土层土壤基质势影响显著，负压计埋置深度对耗水量与土壤基质势变化的相关性影响显著，应依据毛管埋深确定负压计适宜埋置深度。
