| Abstract: In order to explore the function of organic-inorganic compound fertilizer on the growth of mustard, the experiment was carried out to test the effects of different fertilizer application amount on its functional leaves, economic characteristics, disease resistance and yield. The results showed that after the application of organic-inorganic compound fertilizer, the plant grew vigorously, the life span of functional leaves was prolonged, the disease resistance and commercial properties were improved, and the yield was increased significantly. Compared with the application of compound fertilizer, the yield was increased by 8.92%～21.75%, and treatment 4 (taking 100 kg organic-inorganic compound fertilizer + a small amount of special fertilizer as basal fertilizer, top dressing for three times) performed best comprehensively. |
