Abstract： Cantaloupe must ensure sufficient water supplyduring their growth processinordertodevelop normaly.However，inactualproduction，excessive watersupplyoftenleads todeepleakage，whichnotonlywastesresouresbutalso polutes groundwater.Tounderstandtheeffectsofapplying biological-organicfertilizer（BOF）onalleviating nutrietloss caused by irigation in soils withdiffrent textures，soluble BOFwasapplied to poted cantaloupe soils with textures of loam（S1），sand（S2），andclay（S3）uringiigation.Thedrymattermassandnirogen，posphorus，ndpotassumontentof plantsandfruitsafter maturitywere measured，aswellas tephysicochemical propertiesandnitrogen，phosphorus， andpotassiumontentofsoil，rogen，posporus，ndpotasiumcotentinleachate，ndthetentofderttr gen forms.The results showed that compared with no appicationof biofertilizer（CK），BOF treatment significantlyreduced the soil pH，total nitrogen， NO3- -N，total phosphorus，and total potassiumcontent of S1，S2，and S3; significantlyreduced soil conductivity，soil available potassum，soil available phosphorus，soil total nitrogen，soil NO3- -N，and cantaloupe fruit potassium content in S1 and S2; significantly increased the soil NH4+ -Ncontent ofS1，S2andS3;significantly increased the soil conductivity， soil available phosphorus， soil total nitrogen， soil NH4+ -N， soil NO3- -N， cantaloupe plant nitrogen，phosphorus，andpotassumcontent，cantaloupe fruititrogenandphosphoruscontent，ndcantaloupe totalnitro gen，phosphorus，and potassium contentin S3.Therefore，theapplicationofBOFcannotonly improve soilpHand soil conductivity， alleviate irrigation induced leakage of total nitrogen， NO3- -N，total phosphorus，and total potassiumin the soil; and itcanalsoplayaroleinimproving thedrymatter massofswee melon，soilnutrientcontent，andreducing soil nutrient leaching.
