| 摘 要： | 为了有效解决设施蔬菜土壤次生盐渍化问题,实现设施蔬菜生产的健康可持续发展,以南京市江宁区设施蔬菜生产基地为调研对象,通过调查分析后发现设施内土壤pH值显著低于露地,且EC值和NO_3~--N含量显著高于露地,表明设施土壤盐渍化及酸化严重。然后有针对性地提出了相应的解决措施,如选择耐盐品种、改进浇水方法、合理施肥等。

| Abstract: | Abstract: In order to effectively solve the secondary salinization problem of greenhouse vegetable soil and realize the healthy and sustainable development of vegetable production, taking Jiangning district, Nanjing city greenhouse vegetable production base for research object, the investigation and analysis were conducted. The results showed that the pH value in greenhouse soil was significantly lower than that in open fi eld. The EC value and the content of NO3 --N were both higher in greenhouse soil than that in open fi eld, indicating that greenhouse soil suffered serious secondary salinization and acidifi cation. Then some corresponding solution measures were put forward, such as selecting salt tolerant cultivars, improving the method of water and applying fertilization reasonably. |
