五针白皮松生物学特性的研究

A Study on Some Bilogical Characteristics of Pinus squamata

    摘要
  • 摘要: 报道五针白皮松(Pinus squarata X-W-Li)种苗生物学特性,分析了五针白皮松的生长规律.该树种种子品质较差,发芽势弱,针叶出现时间晚于其它松树,4年生前生长缓慢,4年生后生长开始加速,20年生时生长速度超过了云南松(Pinusyunnanensis)等树种.

     

    Abstract: Biological characteristics of seed and seedling on Pinus squarata were reported,and its growth law was analyzed in this paper.The seed quality is worse,germinative energy is weaker,and needling leaves appear later than other species of Pinus.Seedlings grow up slowly before 4 years,and its growth speeds up after 4 years.In 20 years,its growth velocity exceeds P.yunnanensis and so on.
