摘要: 紫胶虫Kerria chinensis Mahd.寄主树是紫胶生产的物质基础,紫胶质量的优劣,除与胶虫的种类或品系有直接关系外,因害主树种类的不同也有明显的差异。为了选择产胶质量好的寄主树种,对我国紫胶生产上常用的:钝叶黄檀Dalbergia obtusifolia Prain、思茅黄檀Dalbergia szemaoensis Prain、南岭黄檀Dalbergia obtusifolia Prain、大叶千斤拔Flemingia macrophylla(Willd)Merr、马鹿花Pueraria wallichii DC.、久树Schleichera oleosa (Lour.)Oken.、宝树Butea monosperma (Lamk,)Taub。Abstract: An analysis has been made on the quality of raw Lac and seed Lac produced by the home Lac insect on 18 species of the host trees respectively after storing for 10 years.The results show that the colour-changing rate of the seed Lac from Butea monosperma,Enterolobium contusiligum and 3 other species of host trees is rather lower than that of the rest.
