Abstract：【Objective】This studyaimed toevaluate the efectsof potassum fulvate-humateorganic fertilizerongoji berries（Lycium barbarum cv.‘Ningqi1’）.【Methods】The experimentincluded thre treatments foliar sprayof potasium fulvate-humateferilizer，potassumfulvatefertilizer，andwater.Theimpactsonoot traits，leafcharacteristics，respirationrate， fruit-bearing branch lengthand diameter，yield，and fruit quality were measured.【Results】The results showed thatthe po tasiumfulvate-humate treatmentsignificantlyoutperformed the potassium fulvateand control treatments insecondary root number，rootactivity，chlorophyllcontent，and photosyntheticrate.Plants treated with potasium fulvatehumateexhibited darkergrenleaveswithhigherglosiness，similartothosetreatedwithpotassiumfulvatebutsignificantlybetterthantecontrol. The highest yield （2514kg/hm2 ） was achieved with potassium fulvate-humate， significantly surpassing potassium fulvate （2388kg/hm2 ）and the control （2082kg/hm2 ），representing increases of 432kg/hm2 and 306kg/hm2 ，respectively. Economically，potassium fulvate-humate increased net income by 3100kg/hm2 and 4900kg/hm2 compared to potassium fulvate andthecontrol.【Conclusion】Foliarapplicationofpotassum fulvate-umateorganicfertilizerimproves thenutritionalstatus， yield，and quality of goji berries，thereby enhancing cultivation profitability.
