Abstract：In order to clarify the practical application effect of black soldier fly sandworm composting in vegetable pro-duction,the effects of four different composting with 0,3％,6％and 9％black soldier fly sandworm on the growth,yield,quality of pakchoi,soil fertility and soil water-soluble salt content were studied by open field cultivation with no fertiliza-tion treatment as CK.The results showed that except for the survival rate and SPAD,all the other agronomic traits of com-posting treatment were higher than those of CK.With the increase of the proportion of black soldier fly sandworm in the composting,the leaf expansion,number of leaves and yield of pakchoi showed an upward trend,and the mass of single plant of pakchoi decreased first and then increased,the pH of the soil decreased,and the water-soluble salt content of the soil at 0-20 cm depth increased.Compared with CK,the yield of C6 treatment increased significantly by 107.63％,while the quality did not decrease significantly.There was no significant difference in soil pH and water-soluble salt content.The content of organic matter increased by 5.95％,and the content of available nitrogen,available phosphorus and avail-able potassium increased significantly by 21.72％,116.83％and 605.38％,respectively.In summary,the black soldier fly sandworm composting(black soldier fly sandworm∶sheep manure∶tomato straw mass ratio of 2∶10∶22)applied by the C6 treatment had the best effect.
