Through long-term stationary field and plot experiments, effects of vegetable type and fertilization structure on nutrient loss with runoff were studied. Results show that nitrogen was the main nutrient element lost from vegetable field with runoff, and followed by potassium and phosphorus. NPK leaching was significantly higher in hot pepper field than in pumpkin field, because the former received a higher rate of fertilizer. P and K leaching was obviously higher in Chinese cabbage field than in cabbage field. NPK leaching from vegetable fields was higher in spring and summer than in fall and winter. At the early growth stage of eggplant, N and P leaching was more serious in CK₂ (local custom fertilization treatment) than in any other treatments. K leaching was higher in Treatment NPK (chemical fertilization) than in any other treatments. In the water samples from the first and second runoffs from Chinese cabbage and cabbage fields, N, P, K contents were higher in CK₂ and Treatment NPK than in any other treatments. At the later growth stage of vegetables, NPK leaching was higher in Treatment OM (organic manure) than in any other treatments and remained high. In Treatment CK₁ (No fertilization), nutrient loss still existed and was quite high, too. It is, therefore, recommended that the management of soil nutrient resources should be intensified to make efficient use of them in the production.
