Abstract： To investigate theappropriate application rate of organic fertilizer for specialty small watermelons， this experiment used the specialty smallorange-fleshed watermelon variety‘Jingcai No.3’as the material. Four treatments were set up： three concentrations of vermicompost—T1 （2 t/667 m2），T2 （4 t/667 m2），T3 （6 t/667 m）and the conventional farmer practice of vermicompost application T4（8 t/667 m2）.Plant height， stemdiameter，yield，and fruit quality were measured.The resultsshowed that the T2and T3 treatments performed relativelywell in terms of plant growth and fruit quality indicators.Based ona comprehensive evaluation of all experimental dataand field performance，itwas recommended that afterreducing the basal fertilizerrateinhigh-fertilitysoils，if thegoalwas tomaximize yield，theoptimalorganic fertilizerapplication rate was 4 t/667 m²，reaching the greatest height（ 2.08% higher than the control） and achieving a relatively highyield（ 5.49% higher than the control）.If the goalwas to optimize fruit quality，an application rate of 6 t/667 m² was recommended， with beter fruit quality，and central sugar content increased by 3.22% （2 compard to the control.Further field trials and demonstrations should be conductedto facilitate the application and promotion of these findings based on market demand and the needs of growers.
