摘　　要：分别研究了不同基肥量和追肥量对有机生态型无土栽培韭菜生长和产量的影响。结果表明,基肥试验总产量和总产值均以基肥量16kg·m-3的处理最高,但纯收入最高的是8kg·m-3处理,且韭菜假茎粗和叶宽与基肥量为12、16kg·m-3的处理差异不显著;追肥试验总产量和总产值均以追肥量7kg·m-3的处理最高,但纯收入以4kg·m-3的处理最高,且韭菜的假茎粗与追肥量为7、10kg·m-3的处理差异不显著,叶宽甚至优于这两个处理。因此,最佳基肥量为每立方米基质施有机生态型无土栽培专用肥8kg,最佳追肥量为每次每立方米基质施有机生态型无土栽培专用肥4kg。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.
