[Objective] The aim was to provide certain theoretical basis for stuides on the high yield and high quality cultivation of Lycium barbarum L.. [Method] Under yield conditons, the accumulation of primary substances and secondary substances of Lycium barbarum L. was studied under different mulching treatments. [Result] Different mulching methods all had a certain effects on the contents of main primary substances and main secondary substances in Lycium barbarum L. fruit. Among them, carbohydrates and flavonoids contents in Lycium barbarum L. were both obviously increased under straw-film mulching; carotenoid content was decreased relatively; hundred leaf weight, 1 000-grain weight and yield of Lycium barbarum L. were increased to a certain extent, but there was no obvious effect on the shape of fruit. Besides, the yield of Lycium barbarum L. had no significant positive correlation with total carbohydrate and polysaccharide, almost had no correlation with flavonoids, and had no significant negative correlation w
