摘要
黄河三角洲地区特殊的土壤条件导致一般苗木因不适应当地的盐碱地条件而不能正常生长,严重制约了造林及城市绿化。对当地耐盐程度高的野生耐盐植物盐地碱蓬[Suaeda salsa(L.)Pall.]进行详细调查和研究,发现了多个适宜重度盐碱地绿化的优势单株,通过单采单种,逐代纯合,选出了2个耐盐程度在2%以上的盐地碱蓬绿化栽培品系。研究了其配套栽培技术,在一定程度上克服了盐碱地依赖客土绿化的弊端,形成具有当地特色的绿化植物种类,丰富了盐碱地区的生物多样性。
General saplings are not adapt to the saline-alkali soil and grow normally under the special soil conditions of the Yellow River Delta. This phenomenon has seriously hampered the afforestation and urban greening. Based on the detailed in-vestigation and researches of the local high salt tolerance of wild halophyte Suaeda salsa （L.﹚ Pall., a number of dominant plants adapting to severe saline were found. Through harvesting and planting alone, and generational purifying, two Suaeda salsa （L.﹚ Pall. greening cultivation strains tolerating salinity level of 2% or more were bred. Supporting cultivation techniques were studied to overcome the reliance on foreign soil greening coastal saline, form greening plant species with local charac-teristics, and enrich the biodiversity of the coastal saline areas.
