| 摘 要： | 为掌握扬州市设施蔬菜园区施肥现状及问题，2013 年在扬州市范围内调查设施蔬菜园区规模、作物品种、施肥现状及运筹，并采集具有代表性园区的土壤样品。结果显示：全市设施蔬菜园区经营方式以企业、企业+合作社方式为主，蔬菜种植以青菜、西瓜、番茄、青椒等常规种类较多。调查的15 个代表性设施蔬菜园区，均以复合肥、有机肥相结合施肥方式，其中复合肥45%型施用较多。与周围大田相比，设施蔬菜园区土壤养分差异较大，其中土壤有效磷、速效钾含量平均为66.1、127.6 mg/kg，分别高于周围大田约300%、30.8%。在调查基础上，初步掌握了设施蔬菜园区的施肥结构、土壤状况，为蔬菜科学施肥提供了数据支撑。

| |
| Abstract: | In order to understand the fertilization status of protected vegetable cultivation in Yangzhou, a survey was conducted on the scale, vegetable species and fertilization status in protected vegetable cultivation of Yangzhou in 2013, and soil samples were collected in typical vegetable zones. The results showed that corporation and corporation cooperative were the general models in the vegetable zones, and green vegetable, watermelon, tomato and pepper were common species. Furthermore, fertilization in fifteen vegetable zones showed that the combined application of compound fertilizer and organic fertilizer was conducted, and the application of compound fertilizer accounted for a larger part. Compared to the soil in field, nutrients in soil of the protected vegetable cultivation zones were higher, especially available P with an average of 66.1 mg/kg and available K with an average of 127.6 mg/kg, which were 300% and 30.8% higher than that of soil in field, respectively. Based on the investigation, soil status and fertilization structures were understood in the protected vegetable cultivation, and the strategies were suggested for proper fertilization in vegetable zones in Yangzhou. |
