不同种源马尾松优树家系在城步的生长表现
|
摘要
以来自湖南省城步、绥宁、通道、会同、安化、浏阳、南岳、慈利、资兴、临武、江永、衡南、茶陵、郴州等14个种源区的82个优树家系种子和城步试验区附近优良林分混合种子(对照)为试验材料,以容器苗造林于城步,对来自不同种源区的家系在城步的生长表现进行研究。结果表明:幼龄期城步本地马尾松优良林分子代表现较好,仅次于江永种源,而浏阳、通道种源幼龄期和中龄期平均胸径均显著小于城步马尾松优良林分子代的,但随着林龄的增长,资兴、会同、江永、临武种源的树高、胸径、材积的表现均逐渐超过了本地优良林分子代的表现。以11年生材积排名,表现最好的是来自于资兴的家系,排前5名的有4个(含前3名);来自于江永的家系表现较好,仅次于资兴的,排前5名的有1个。以11年生材积生长量为优良家系选择标准,按家系总数15%的入选率,江永家系的入选率最高,达50.0%;资兴的次之,为41.2%;临武的较小,为23.1%。马尾松家系的生长表现在幼龄期和中龄期有一定有差异,早晚表现一致的家系仅占50%。
The experimental materials of 82 superior tree families seeds of Pinus massoniana of 14 provenance area from Hunan Province were taken by follows counties of Chengbu County, Suining County, Tongdao County, Huitong County, Anhua County, Liuyang City, Nanyue County, Cili County, Zixing City, Linwu County, Jiangyong County, Hengnan County, Chaling County, Chenchou City, and the hybrid seeds(control) in superior forest stand of experiment area near Chengbu County. Taking the container seedling afforestation in Chengbu County, the growth performance of all superior tree families of P. massoniana from different provenances in Chengbu County were studied. The results show that good growth in the young stage of local superior tree families of P.massoniana filial generation in Chengbu County, just second only to the provenance in Jiangyong County.The average DBH of young and middle age of P.massoniana of provenance of Liuyang City and Tongdao County are significantly less than local superior tree families of P.massoniana filial generation in Chengbu County. But with the increase of forest age,the height, DBH and volume of P.massoniana of provenance of Zixing County, Huitong County, Jiangyong County and Linwu County are more than the performance of local superior tree families of P.massoniana filial generation in Chengbu County. In the volume ranking of 11-year-old P.massoniana families, the best performers are from families of Zixing County, with 4 families of the top 5(including the top 3).The P.massoniana family performed better of Jiangyong County, which second only to the Zixing County family, with 1 family in the top 5. Taking the volume of 11 year-old P.massoniana as the superior family selection stand, and with the selection rate of 15% of the total number of families, the families of Jiangyong County had the highest selection rate of 50.0%; the families of Zixing City was second with 41.2 %;the families of Linwu County was third with 23.1%. The growth performance of P.massoniana families have obvious difference in young age and middle age, and only 50% of the families show the same performance in early and late age.
