我们于1981年在云南省思茅松自然分布区域内,收集了六个思茅松种源,按统一的实施方案在五个不同气候类型的栽培点上进行造林对比试验,研究思茅松的地理遗传变异与环境的关系,为思茅松的种子调拨区划提供科学依据。本文分析总结了各栽培点上3年生时的情况,思茅松种源间树高生长的差异是显著的,表现好的种源比生长差的种源提高23.9％～58.2％,比各点云南松对照种源提高0.81—2.2倍。从而看出选择适宜的思茅松种源造林,可望得到一定的增产。
In 1981, in the natural distribution area of Pinus kesiya in Yunnan Province, we collected six provenances of Pinus kesiya var. Angustifolia, carried out comparison experiment on afforestation of five different climatic types according to a unified plan, and studied the geographical genetic variation And the relationship between the environment, to provide the scientific basis for the seed allocation Zhai Mao Song. This paper analyzed and summarized the situation of three-year-old on each cultivation point. The difference of tree height growth among provenances of Pinus kesiya was significant, and the good provenance increased 23.9% -58.2% compared with that of poor growth, Pine control provenance increased 0.81-2.2 times. Thus we can see that the appropriate species of Pinus kesiya Forest Afforestation, is expected to be a certain yield.
