我国自七十年代开始对刺槐进行遗传改良,现已选出了一批优良无性系品种。但由于刺槐嫁接、硬枝扦插、插根育苗等无性繁殖技术操作麻烦、繁殖系数低,使这些优良品种难以迅速推广应用。为此,1985年以来,我们对刺槐细根段育苗技术进行了深入研究,找到了省工、省时、繁殖系数高、适宜不同立地条件区的刺槐快速繁殖法。 China since the seventies began genetic improvement of black locust, has now been selected a number of excellent clonal varieties. However, cloning, hardwood cuttings, seedling nursery and other asexual propagation techniques are cumbersome and the breeding coefficient is low, making it difficult for these excellent varieties to be popularized and popularized. To this end, since 1985, we have carried out in-depth research on fine root seedling nursery technology of locust and found the rapid propagation method of locust which is suitable for different locality conditions in terms of labor-saving, time-saving, high propagation coefficient.
