摘 要:20多年来在云南省昆明、蒙自、建水、个旧等地所开展的马尾松引种试验的结果,营造示范林及推广应用的结果证实:马尾松在云南较大范围内的引种收到了好的效果。其马尾松林单位面积的材积生长量超过了对照云南松林的1 5倍,比同等条件下评选出来的云南松优良种源林提高14 8%~64 5%;马尾松在云南引种区域内,能正常开花结实,且种子的千粒重、饱满度、发芽率、发芽势均好;马尾松木材的气干密度、干缩系数、质量系数、力学性能与云南松相当,有的指标还稍有超过。Pinus massoniana has been introduced to Yunnan in the site of kunming, Mengzi, Jianshui, Gejiu for 20 years, the results of demonstration forest and extending plantation proved that the introduction of Pinus massoniana to a large area of Yunnan was successful. Wood volume of Pinus massoniana is 1.5 times large of contract forest of Pinus yunnanensis, enhancing 14.8%~64.5% than the forest of Pinus yunnanensis which was selected by the same qualification. In the introduction area, the Pinus massoniana bloomed and fruited in the course of nature, and the characters of seeds, such as the weight of one thousand seeds, plump degree, germination rate , germination energy and so on are good. The specific gravity in air dry, drying shrinkage rate, specific gravity rate, mechanical properties are the same or a little better than those of Pinus yunnanensis.
