本文研究了臭椿播种育苗雌、雄分化比例:证明雄性在生长速度、干型以及生态适应幅度方面优于雌性;确认雄性是臭椿中的一个优良类型。为了在生产中推广应用雄性臭椿,进而对插根育苗技术进行了试验,并且探讨了当年生插根苗的根系发育及其产根量,认为建立优良雄性臭椿采根圃,生产种根,培育插根苗的方法是可行的。 In this paper, we studied the ratio of male and female differentiation of sowing seedlings of Ailanthus altissima. It was proved that males were superior to females in terms of growth rate, dry type and ecological adaptability. It was confirmed that male was a good type in Ailanthus altissima. In order to popularize the application of Ailanthus altissima in production, the experiment of inserting seedling was carried out, and the root development and yield of inserted root seedlings were also discussed. It is considered that the establishment of good male Ailanthus altissima root nursery, Root seedling method is feasible.
