无刺槐(Robiaia Pseudoacacia Var inermis Dc)是刺槐的一个变种。其树冠园整美观,枝叶浓绿,荫覆量大,忌水抗旱,耐寒,是西北广大城市绿化的优良树种之一。刺槐主要靠种子繁殖,优良种系采用嫁接和埋根法,但无刺槐,异花授粉力强,天然杂交率高,种子的种性不易保持,嫁接和埋根的成本又高,速度也慢,达不到快速繁殖目的, Robinia pseudoacacia var inermis Dc is a variant of Robinia pseudoacacia. The Crown Park, the whole beautiful, foliage dark green, a large amount of shade, avoid water drought, cold, is one of the fine trees in the vast northwest city greening. Robinia pseudoacacia mainly relies on seed propagation, and excellent germplasm adopts grafting and burying root method, but without Robinia pseudoacacia, cross-pollination, natural hybridization rate is high, seed species is not easy to maintain, grafting and burying costs are high and slow , Reach the purpose of rapid breeding,
