摘要
在普洱市选择40个思茅松优良无性系容器嫁接苗,以当地实生苗为对照,开展思茅松山地造林试验,观测林木的树高、胸径生长量。调查分析结果表明,不同无性系间在高、径、材积生长上均达到极显著差异水平,表现较好的有37、31、8、3、9、11、19、7、1、30、14、12、13、2、40、33、15号无性系,共17个,这些无性系已定植19年,林木生长量已稳定,可作为思茅松优良无性系,为当地提供优质的思茅松嫁接苗、扦插苗繁殖材料。
The container grafted seedlings of 40 superior clones of Pinus kesiya var.langbianensis were selected in Pu′er City,and the local seedlings were used as the control to carry out the mountain afforestation experiment and observethe growth of tree height and DBH.The results showed that the growth of height,diameter and volume among different clones reached extremely significant level,and the clones with better performance were 37、31、8、3、9、11、19、7、1、30、14、12、13、2、40、33 and 15 clones,which had been planted for 19 years with stable growth status,and could be used as excellent clones of Pinus kesiya var.langbianensis to provide high-quality grafted seedlings and cuttings for the local area.
