据调查,目前全国紫胶寄主树约有300余种,应用于紫胶生产的优良树种不过10余种。我省紫胶产区常用寄主树仅有南岭黄檀、牛肋巴和秧青等几个树种,远远不能适应发展紫胶生产的需要。为挖掘紫胶寄主新种源,1970年,我们首次试用野生黄(木巳)放养夏代紫胶虫,获得成功。经过多年放胶实践证明,黄(木巳)不仅适宜夏代紫胶生产,而且能够高产、稳产,并具有生长迅速、萌发力强、耐虫力高、胶质好、胶被厚而连片的优良性状。现介绍如下: According to the survey, at present, there are about 300 species of lacrosse host trees in the country, but more than 10 species are used in the excellent species of shellac production. The common host tree of Lac in Zhejiang Province is only Nanling Dalbergia, Niu Leba and young seedlings such as several tree species, far from being able to adapt to the needs of the development of shellac production. In order to explore new germplasm source for lac host, in 1970, we first tried wild yellow larvae for success. After years of practice, it has been proved that Huang (Matsuba) is not only suitable for the production of shellac in Xia Dynasty but also capable of high yield and stable yield with rapid growth, strong germination, high tolerance to insects, good glial, thick and contiguous glue Good traits. Now introduced as follows:
