A pot experiment was conducted to study the effects of hermetia illucens sandworm with the addition ratio of 10%，20%，30% and 40% on the growth，quality of Amaranthus mangostanus L .，Gynura cusimbua and Spinacia oleracea L. and the soil nutrient contents，so as to provide references for the utilization of Hermetia illucens sandworm.The results showed that there were significant differences in plant height，biomass and chlorophyll content of Amaranthus mangostanus L.，Gynura cusimbua and Spinacia oleracea L.after applying Hermetia illucens sandworm compared with the control. The average chlorophyll content of the three vegetables were 1.1，1.1 and 1.2 times of that of the control treatment.The plant height were 9.8，3.0 and 2.9 times，and the fresh weight were 63.2，14.8 and 61.5 times，respectively.The quality of the three vegetables was also improved after the application of Hermetia illucens sandworm.The contents of vitamin C，soluble sugar and sosuble protein were 3.1，1.9 and 1.4 times higher than those of the control，respectively.The best application amount of Hermetia illucens sandworm was 20%.If the application rate is too high，it will inhibit the growth and lead to the decline of vegetable yield and quality.The content of soil organic matter increased by up to 22.0%，the content of total nitrogen，total phosphorus，total potassium and available phosphorus were 2.6，1.9，1.2 and 23.7 times as much as that of the control.Therefore，Hermetia illucens sandworm can be used as a kind of organic fertilizer with better fertilizer efficiency in vegetable cultivation.However，soil acidification and salt accumulation after long-term application should be paid attention.
