马尾松是贵州省飞播造林的主要树种。由于飞播造林具有绿化速度快,成本低,集中成片的特点,目前仍不失为迅速绿化荒山,建立森林后备资源的有力措施之一。飞播马尾松林的林分特点,生长过程有别于天然更新和人工造林形成的林分。为了使大面积的飞播马尾松林正常生长,保证成材,提高生产率,研究其生长特点,制定相应的经营措施是非常必要的。调查研究是在贵州省独山县城关区、惠水县三都区等播区进行的,立地条件分别为下等和中等。
Masson pine is the main species for aerial seeding in Guizhou Province. As the aerial seeding afforestation has the characteristics of fast afforestation, low cost and concentration into pieces, it is still one of the powerful measures to establish the reserve resources of the forest rapidly nowadays. Fly forest Pinus massoniana characteristics, the growth process is different from the natural regeneration and the formation of artificial afforestation. In order to make the large-scale aerial seeding of Pinus massoniana forest grow normally, ensure the production, improve the productivity, study its growth characteristics and formulate the corresponding management measures are very necessary. The investigation and study were carried out in Chengguan District, Dushan County, Guizhou Province and sowing areas in Sandu District, Huishui County. The site conditions were lower and medium.
