Abstract In this paper，the effect of different doses of base fertilizer and top dressing fertilizer on the growth and yield of Chinese chive of Eco-organic type soilless culture（EOTSC）was studied.The results showed that the treatment of 16 kg·m-3 base fertilizer can have the highest total yield and total production value，while 8 kg·m-3 of base fertilizer dose can get the highest net income，and there were no remarkable differences between pseudostem width and leave width with the treatments of 12 and 16 kg·m-3 base fertilizer.In the experiment，treatment with 7 kg·m-3 of top dressing fertilizer can get the highest total yield and total production value，but the treatment of 4 kg·m-3 can get the highest net income，and there were no significant differences in pseudostem width with the treatments of 7 and 10 kg·m-3.The leave width was even better than that in the above 2 treatments.Therefore，in EOTSC the best base fertilizer dose is 8 kg·m-3 and the best top dressing fertilizer dose is 4 kg·m-3 per time.
