马尾松(Pinus massoniana Lamb.)是我国亚热带地区主要用材树种之一,具有分布面积广、生长快、经济效益高等优点。它又是典型的外生菌根树种,抗逆性强,适应性广,是我国荒山绿化的先锋树种。研究表明,马尾松苗木菌根感染率不同,对其造林成活率有着明显的不同,且菌根化苗木造林后缓苗期短,生长快,株高、茎粗、新梢高度均大大超过无菌根化苗木。因此,马尾松苗木菌根化是十分必要的。
Pinus massoniana Lamb (Pinus massoniana Lamb.) Is one of the main timber species in the subtropical region of China. It has the advantages of wide distribution area, fast growth and high economic benefits. It is also a typical ectomycorrhizal species, strong resistance, wide adaptability, is the pioneer tree species in China’s barren hills. The results showed that the infection rate of seedling mycorrhizal was different, and the survival rate of afforestation was obviously different. The seedlings of mycorrhizal seedlings had short remission period, fast growth, plant height, stem diameter and shoot height significantly Mycorrhized seedlings. Therefore, Masson pine seedling mycorrhizal is very necessary.
