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。
Tamarix gallica cv.DY-1 is an excellent clonal propagation of cuttings from Tamarix gallica L., introduced from Hungary. Through the cutting propagation experiment, pot experiment and field experiment, the salt tolerant ability of Tamarix ramosissima was mastered, and the cutting propagation technology of coastal saline soil in the Yellow River Delta was explored. Prickly ash willow is more tolerant to salt stress and can grow normally in the soil with a salt content of 15 g · kg-1, with a salt tolerant limit of about 24 g · kg -1, which is an excellent tree species for the greening of saline soil Weeping branches tamarisk branches, drought-resistant, barren, fewer pests and diseases, suitable for planting in saline soil in barren Yellow River Delta.
