本文论述了巴山松在形态特征上与油松、马尾松的异同,调查分析了黎坪林场天然马尾松林的生长及起源。研究结果表明,按照植物分类的观点,巴山松作为一个独立的种是有依据的。在较好的立地条件下,巴山松能发挥更大的生产潜力。最大高生长一般出现在20—30年,胸径年生长量最高值出现在20年左右,80—90年材积年生长量达到最高峰。
The paper discussed the morphological characteristics of Pinus tabulaeformis and Pinus tabulaeformis and Pinus tabulaeformis and analyzed the growth and origin of natural Pinus massoniana forest in Li ping farm. The results show that according to the classification of plant species, Pinus sylvestris as a separate species is based on. Under better site conditions, Bashan Song can play a greater production potential. The maximum height growth generally occurs in 20-30 years. The maximum annual growth of DBH occurs at about 20 years, and the volume annual growth reaches the peak in 80-90 years.
