【Objective】The study aimed to clarify the application of biochemical fulvic acid potassium product on the survival rate and growth of various trees transplanted in the process of landscaping. 【Method】In this study, two experimental treatments(i.e. decomposed organic fertilizer + biochemical fulvic acid potassium water soluble fertilizer, decomposed organic fertilizer + compound fertilizer) were set up to determine the changes of physical and chemical properties before and after soil treatment, and the survival rate, plant height and ground diameter of four different cultivated plants in one year, and the effects of adding biochemical fulvic acid potassium on cultivated plants were investigated. 【Result】The results showed that the soil organic matter, total nitrogen, alkali-hydrolyzable nitrogen, soil available phosphorus, soil available potassium, the pH value in the soil treated with decomposed organic fertilizer + biochemical fulvic acid potassium soluble fertilizer, decomposed organic fertilizer + compound fertilizer increased significantly, and the soil bulk density decreased obviously. The survival rate, plant height and ground diameter of the four different cultivated plants were significantly improved after the treatment with decomposed organic fertilizer + biochemical fulvic acid potassium water soluble fertilizer, decomposed organic fertilizer + compound fertilizer(P<0.05). 【Conclusion】The application of biochemical fulvic acid potassium on cultivated plants and effectively improve soil fertility, increase the utilization of nitrogen, phosphorus and potassium, improve the growth of plants, and promote the landscaping plants.
