Masson pine is one of the main afforestation and timber species in our district, with the most extensive distribution area and the largest stock volume, and is the main source of craters, sleepers, papermaking materials, turpentine and civil timber in some areas. Due to its wide adaptability, Strong propagation, afforestation easy, rapid growth, faster, at the same time in most of my hilly areas can be under the kind of natural regeneration, so popular with the masses.But because of different environmental conditions, and long-term natural and artificial However, the result of natural selection is mainly a result of many different varieties and types, and their growth speed, morphological characteristics, genetic traits, and economic traits are mixed with each other.
