| Abstract: In order to study the effect of seaweed fertilizer on the yield and quality of pakchoi, pakchoi cultivar 'Huangmeigui' was taken as the research object, three levels of treatment were set, which applied 5, 10 g and 15 g per 667 m2 of seaweed fertilizer, respectively. Compared with no seaweed fertilizer (control), the plant characters and quality traits of pakchoi under different treatments were analyzed. The results showed that the plant height, leaf number, weight per plant, dry matter weight, yield and vitamin C content were significantly increased by seaweed fertilizer treatments compared with the control. There were no significant differences in stem circumference, plant width, ratio of stem and leaf, root weight and soluble sugar. Among them, the application of seaweed fertilizer with 10 g per 667 m2 was the best treatment, with the contents of soluble sugar and vitamin C of pakchoi increased by 14.3% and 25.2%, respectively, and the yield per 667 m2 increased by 19.5%. |
