华山松种子区区划及贵州用种调拔区

Division of Seed Zones and Guizhou's Zone of Seed Allotment in Pinus Armandi Franch

我省华山松种源研究多点试验结果,将华山松分布区划分为3个种子区和4个种子亚区。贵州属云贵高原种子区的北部亚区,其生产用种的调拨,除本省威宁、赫章种子外,可调用本亚区内云南东川、会泽,四川会理、会东的种子;云贵高原南部亚区(云南保山、腾冲、梁河、昌宁)是贵州华山松生产用种优良供种区,比本省威宁种子有更大的增产潜力。但决不能调用秦巴山地生产的种子,以免造成损失。

In this text natural range of pinus Aramandi is divided into three seed zone and four seed subzone.Guizhou belongs to thenorthern subzone of the seed zone of Yunnan-Guizhou plateau.Besides the seed collection in weilin and Hezhang of ourprovince,Wecan allot the seed in this subzone of Dongchuan,Huize in Yunnan and Huili,Huidong in Sichuan.The southernsubzone of Yunnan—Guizhou Plateau (Yunnan Tengchong,Baoshan,Lianghe,Changning etc.) is a superior seed zone ofthe seed collection of Guizhou.It has great increase production potentialities than that in weilin of our province.Guizhou ab-sorlutely cant allot the seed in the seed zone of Qinling—Bashan Mountain.
