针对我国南方大部分地区营建松树纯林,造成生态环境不良的状况,选择多种阔叶树,如红椎、大叶栎、稠木、荷木、火力楠、台湾相思、绢毛相思、马尖相思、黑荆树、紫荆木等,与松树实行异龄混交,采用截干苗、早栽、适当的混交比例等造林技术,混交林面积达0.7万hm2。混交的阔叶树种,成活率90%以上,林分生物产量比松纯林提高10%。大面积的异龄松阔混交林,改善了林区的生态环境。
For the construction of pure pine forest in most parts of southern China, resulting in poor ecological environment, choose a variety of broad-leaved trees, such as red vertebrate, big leaf oak, thick wood, Dutch wood, fire Nan, Taiwan Acacia, Amoeba acacia, , Black wattle, Bauhinia wood, and the implementation of heterosis mixed with pine, truncated stems, early planting, the appropriate proportion of mixed techniques of afforestation technology, mixed forest area of 7,000 hm2. Mixed broad-leaved species, the survival rate of 90% or more, stand biomass increased by 10% than pure pine forest. A large area of mixed pine coniferous forest, improve the ecological environment in the forest.
