刺槐是半干旱地区荒山造林的主要树种之一,但由于有性繁殖使刺槐品质严重退化,表现为造林成活率低、生长速度缓慢、材质差等,不符合营造速生丰产林的要求。而刺槐优良无性系具备用途广、抗逆性强、成林快等优点,适合在半干旱地区大面积推广应用。基于此,本研究介绍刺槐优良无性系推广的重要性、品种及其栽培技术,为林业生产提供原料和技术支持。
Robinia pseudoacacia is one of the main tree species afforestation in barren hills in semiarid area. However, due to sexual reproduction, the quality of Robinia pseudoacacia is seriously degraded. The performance of Robinia pseudoacacia is low survival rate, slow growth rate and poor quality, which are not in line with the requirements of fast-growing and high-yielding forests. The acacia locust clones with a wide range of uses, strong resistance, fast forest, etc., suitable for large-scale popularization and application in semi-arid areas. Based on this, this study introduced the importance of promoting the excellent clones of Robinia pseudoacacia, cultivars and their cultivation techniques for forestry production to provide raw materials and technical support.
