四角风车子(Combretum quadruangulare kurz)隶属使君子科风车子属。该属除澳洲外,所有热带地区均有分布,尤以非洲分布较多。我国有12种,主要分布在云南、广东和广西等省(区)。该属多为灌木状,枝条又少,不能作紫胶虫寄主树利用。本试验所引用的四角风车子属乔木树种,分枝萌发习性较好。四角风车子在泰国东部呵叻高原分布较多,用作繁殖优良紫胶虫,增产效果明显,少数地区也作为原胶生产利用,此种在我国尚未有记载。为了探索提高原胶质量,1980年我们从泰国引种,在云南省景东县进行栽培与放胶试验。
Combretum quadruangulare kurz under the subordinate genus Branch windmill car. The genus in addition to Australia, all tropical regions are distributed, especially in Africa more distribution. There are 12 species in our country, mainly in Yunnan, Guangdong and Guangxi provinces (districts). The genus is mostly shrubs, branches and less, can not be used as shellac host tree. The four corners of the test quoted the windmill tree arbor species, branch germination habits better. Corner windmill in Thailand Nakhon Ratchasima Plateau more distribution, used for breeding excellent lac bug, yield-producing effect is obvious, a few areas are also used as the production of raw gum, such in our country has not been documented. In order to explore and improve the quality of the original gum, we introduced it from Thailand in 1980 and conducted cultivation and plasticizing tests in Jingdong County, Yunnan Province.
