大叶速生槐种根育苗技术研究

摘要

[目的]提高大叶速生槐种根的繁殖系数和苗木的质量.[方法]对不同直径不同长度的大叶速生槐种根的繁殖方法进行研究.[结果]直径5 mm以上的种苗种根采用直接栽种的方法,直径3～5 mm的种根采用先育苗再移栽的方法,育苗主要采用沙坑密植、营养袋育苗和塑管育苗等方法.[结论]此法不仅提高了大叶速生槐种根的繁殖系数,而且提高了苗木的质量.%(ObjectiveJTo increase the propagation coefficient and seedling quality of Robiaia pseudoacacia L.. [ Method] Various methodsrnwere employed to germinate roots of different diameter and different length. [ Result ] Roots with diameter larger than 5 mm were planted direct-rnly , and roots with diameter of 3 -5 mm were germinated first and then transplanted to the field. [Conclusion] Propagation coefficient and seed-rnling quality were both increased with these methods.
