云南石梓,马鞭草科,学名GmeIina aborea。生长迅速,干形通直,抗虫性强,材质较好;在本岛种源缺乏。而海南石梓在生长速度,干形及抗虫能力(抗石梓金花虫及金龟子为害)均比云南石梓差。但其种源在本岛较多。本试验的目的,通过海南石梓嫁接云南石梓,以建立云南石梓种子园,解决云南石梓种源不足问题;同时摸索用海南石梓砧嫁接苗营造云南石梓用材林的可能性。
Yunnan Shi Zi, Verbenaceae, scientific name GmeIina aborea. Rapid growth, dry straight, strong insect resistance, good material; lack of provenance in the island. However, the growth rate, stem shape and pest resistance of Hainan Shizi were worse than those of Shiqi in Yunnan Province. However, its provenance is more on the island. The purpose of this experiment, through grafting Hainan Shi Zi Yunnan Shi Zi, to establish Yunnan Shi Zi seed orchard, to solve the lack of provenance in Yunnan Shi Zi; at the same time to explore the use of Hainan Shi Ziwei grafted seedlings to create the possibility of Yunnan Shi Zi timber.
