A study was conducted in the Shandong province in North China to investigate the effectsofdifferentplantingpatterns on water potential characteristics of soil-plant-atmosphere continuum (SPAC) and yield of summer maize. Threeplantingpatternswereapplied,i.e.bedplanting(BE),furrowplanting(FU)andflatplanting(FL).Theresultsshowed that although soil moisture content in 0–20 cm soil layer in BE was decreased, soil temperature was increased; as a result, soil water potential in BE was increased. Compared with FL, leaf water potential in BE and FU was enhanced, but water transfer resistance between soil-leaf and leaf-atmosphere was decreased; feasible water supply conditions were thus created for crops colony. Maize yield of BE and FU was significantly(LSD,P < 0.05) higher than that of FL, by 1326.45 and 1243.76 kg/ha, respectively. Theseresultsobtainedinfieldcropconditionssupportthe idea that planting patterns affectsoilwaterpotential,leafwaterpotential,watertransferresistancebetweensoil- leaf and leaf-gas of summer maize in North China
