科尔沁沙地班克松和小干松种源试验

Provenance Tests of Pinus banksiana and Pinus contorta on Keerqin Sand Land

班克松(Pinus banksiana)和小干松(Pinus contorta)从1990年引种到辽宁省彰武县章古台沙地15年,具有较强的抗旱性和一定的速生性,长势良好。为此,1999年在辽宁省彰武县章古台开展了种源试验,通过对班克松13个种源、小干松5个种源6年的对比试验,选择出班克松最佳种源为43号、47号、49号、52号,小干松37号和38号种源相对较好。

The trees Pinus banksiana of and Pinus contorta introduced to Zhanggutai in Zhangwu Liaoning Province in 1990 were resistant to drought with nice performance. In the comparison of provenance trial took on 13 provenance of Pinus banksiana and 5 of Pinus contort in 1999. Seed sources No. 43, 47, 49 and 52 of Pinus banksiana were the best of 13 sources tested, and Seed sources 37 and 38 were relatively well among the 5 sources tested. It was recommended to introduce the two species from best seed sources and improve it survive proportion to enrich local sand tree species sources.
