摘要
为了科学合理的保护管理云南古茶树种质资源的多样性及有限的面积,该文对古茶树进行了重新的界定,共包括大厂茶、大理茶、厚轴茶、秃房茶和茶5种,以及普洱茶和白毛茶2变种。拟合的胸径与年轮数之间的S型函数表明,当树龄为100 a时,胸径约为18cm;由胸径按树木干型的削度换算结果表明,100a古茶树的地径为22.50cm。因此,胸径大于或等于18.00cm,或者地径大于或等于22.50m的茶树为古茶树。另外,建议将古茶树按林地权属性质分为严格保护型、部分(非生产性)利用型和生产利用型3类保护利用类型,并开展相应的保护管理措施。以上内容的论述,既可为云南省古茶树(园)资源的合理保护和科学管理提供依据,又可满足人们对古茶树利用的需求。
In order to protect and manage the diversity and limited areas of Yunnan ancient tea tree germplasm resources scientifically and reasonably,ancient tea tree was redefined in this paper.Ancient tea trees refer to Camellia tachangensis F.C.Zhang,C.taliensis(W.W.Smith)Melchior,C.crassicolumna Chang,C.gymnogyna Chang,C.sinensis(L.)O.Kuntze,C.sinensis var.assamica(Masters)Kitamura and C.sinensis var.pubilimba Chang.The fitted S type function between the DBH and the number showed that when the age of tree was100a,the diameter at breast height(DBH)was about18cm;The scaling results of stem diameter at breast height according to the tree dry type suggested that the basal diameter of the100a ancient tea tree was22.50cm.So,the DBH of the ancient tea tree was larger than or equal to18cm,or the basal diameter was greater than or equal to22.50cm.In addition,it was suggested that the ancient tea tree should be divided into three types:strict protection type,partial(nonproductive)utilization type and productive utilization type according to the nature of forest land ownership.And the corresponding protection measures and management measures should be carried out.The above contents discussed could provide the basis for the reasonable protection and scientific management of ancient tea tree resources in Yunnan Province,and meet the needs of the utilization of ancient tea trees.
