【摘要】 多花垂枝柽柳(Tamarix gallica cv.DY-1)是从匈牙利引进的红花多枝柽柳(Tamarix gallica L.)中选择自然变异的单株经扦插繁殖而成的优良无性系。通过扦插繁殖试验、盆栽试验以及大田栽培试验,掌握了多花垂枝柽柳的耐盐能力,探索出在黄河三角洲滨海盐渍土的扦插育苗技术。多花垂枝柽柳耐盐能力强,可在含盐量15 g·kg-1的土壤中正常生长,耐盐极限在24 g·kg-1左右,是重度盐渍土绿化的优良树种;多花垂枝柽柳分枝力强,耐旱、耐瘠薄,病虫害少,适宜在黄河三角洲贫瘠的盐渍土上种植。更多还原

【Abstract】 The natural variability plant was selected from Tamarix gallica L. introduced from Hungary,then we obtained superior clones-Tamarix gallica cv. DY- 1 by cutting propagation. Through cutting propagation experiment、pot experiment and field cultivation experiment,we mastered the Tamarix gallica cv. DY- 1 salt resistance ability and explored on the cuttage propagation techniques of coastal saline soil in the yellow river delta. Tamarix gallica cv. DY- 1 is a kind of plant with strong salt tolerance and can grow normally soil salt content 15 g·kg- 1,salt tolerance limit 24 g·kg- 1around. Tamarix gallica cv. DY- 1 is an excellent species for afforestation of severe saline soil. Tamarix gallica cv. DY- 1 has excellent characteristics of strong branches,drought resistance,barren tolerance and resistant to insect pests and is suitable for planting planting in the yellow river delta barren saline soil.更多还原
