Abstract：Thisstudyaims toscreeoutsuitablepointsforthecultivationofwhitekonjacinthephotovoltaicshadingareas.With the planting point （D） not affected byphotovoltaic shadingas the control，the effects of1/4 （A），1/2 （B），and 3/4 （C） below the photovoltaicpanelmoduleonthephotosyntheticproperties，growth，yield，andqualityofwhiteonjacwereexplored.Teresults showed thatthelight intensityunder the photovoltaic panels at diffrent meterorologicalconditions followed the trendof D>C>A> B.Atthe uber expansionstageand matuitystage，thenetphotosyntheticrate，transpirationrate，andstomatalconductance werein the order of C>A>B>D ，while the intercellular CO2 concentration followed the trend of D>B>A>C. At the maturity stage， the leafdiscdiameterand plant height atpointCwere significantlyhigher than those atotherpoints.Compared with pointDpoint C showed significant increases of 84.57% ， 20.77% 3.68% ，and 14.84% in the yield， glucomannan， soluble protein， and soluble sugar， respectively，of white konjac.Inconclusion，it is recommended that white konjaccanbe cultivated atthe point 3/4 below photovoltaic panels.
