The changes of rhizosphere soil enzymeactivity，soil nutrient content and its effect on Lily bulb yield was investigated to provide reference for overcoming continuous cropping obstacles and organic fertilizer substitution for chemicalfertilizer management in the production process of edibleLily.Different combinations of potassium fertilizer and organicfertilizer were used to determine the effects of different treatments on soil enzymes and soil nutrients in 0～ 20 cm soillayer，plant nutrients and yield of edibleLily.Firstly，the activities of sucrase，alkaline phosphatase and urease in the rhizospheresoil of edible Lily were the highest under the conditions of high potassium fertilizer and high organicfertilizer，and the effectof potassium fertilizer on enzyme activity was stronger than that of organic fertilizer.Especially in the late growth stage ofLily，the effect of fertilizer combination was moreobvious，and the response of soil enzyme activity to organic fertilizer wasmoreactive.At the same time，the response of the content of soil nitrate nitrogen and available potassium to the gradient of potassium fertilizer and organic fertilizer application showed a trend of continuous decline in growth difference, and the difference between the content of available phosphorus and the former two was that the content of available phosphorusdecreased with the increase of potassium fertilizerapplication.Inaddition，potassium fertilizer combined with organicfertilizer increased the bulb yield most significantly under both high fertilizer application.Soil enzymes，nitrate nitrogen，available potassium and bulb yield had significant or extremely significant positive correlation，while available phosphorushad weak correlation.Potassium fertilizer and organic fertilizer treatment can improve individual development level and soilenvironment，store abundant substances and regulate soil nutrient status for Lily growth in the next year.
