不同基质旱冬瓜扦插繁殖技术研究

A Study of Different Matrix Cutting Propagation Technique of Alnus nepalensis

不同基质旱冬瓜扦插试验中,采用完全随机区组设计,在云南省林业科学院热带林业研究所(普文)扦插旱冬瓜在森林土、河沙和珍珠岩3种基质中,最适宜的为森林土,平均生根率为43.57%,平均生根数为6.06条,平均抽稍长度为4.26 cm,平均最长根长为9.39 cm。

In different matrix of Alnus nepalensis cutting test, use was made of a completely randomized block design. For cutting Alnus nepalensis in three matrix （forest soil, river sand and perlite） in Re- search Institute of Tropical Forestry of Yunnan Academy of Forestry（Puwen） , soil. The average rooting rate was 43.57%, the average number of roots was 6. length was 4.26 cm, and the average root length was 9.39 cm. the most suitable was forest the average branching
