浙江温州瓯江口新区新围涂地治理对策及改良绿化技术研究

Treatment Measures and Improved Greening Technologies for Reclamated Tideland Region at Oujiangkou New District in Wenzhou, Zhejiang

针对浙江温州瓯江口新区新围涂地土壤含盐量高、质地黏重、通透性差、氮磷含量低、体积质量大等障碍因子,重点阐述了碴石盲沟(填料暗沟)排水的优越性和必要性,以及排水标准、排水规格(埋深、间距)等。同时提出潮滩盐土原土改良绿化的排水洗盐、改土培肥、覆草套种、支撑密植等综合措施。

To eliminate the large obstacles such as high salinity, sticky and heavy soil, poor permeability, low content of nitrogen and phosphorus and large volume mass of the soil of the reclamated tideland region at Oujiangkou new district in Wenzhou, Zhejiang, the advantages and necessity for fragmented-stone-stuffed underground drain ditch, and the drainage standard and specifications （embedding depth and gap） etc. were elaborated particularly. At the same time, comprehensive measures including salt filtration through drainage, soil improvement through fertilization enhancement, supporting and close planting were put forward for soul improvement and greening of tideland saline soil.
