具有“绿色金子”之称的印楝在云南已经初步形成了规模化的种植基地,深加工研究和产品开发达到国内领先水平,从而带动了一种无公害生物农药生产体系在云南的形成。印楝属于楝科楝属常绿乔木,适宜生长在无霜冻的干热河谷地区。1965年,一名德国科学家在苏丹发现,蝗虫灾害毁灭了大量植物,惟有印楝树在蝗虫肆虐后安然无恙,于是开始了对印楝的研究。经过长期研究,科学家发现印楝的树根、树干、树皮、树叶、花、果实、种子,全都是“宝”。从果实中分离提取的印楝素是世界公认的广谱、高效、低毒、易降解、无残留的杀虫剂,能驱杀200多种农业、林业、仓储和卫生害虫,特别是对驱杀鳞翅目、鞘翅目及双翅目害虫有特效。1995年,中国林科院昆虫资源昆虫研究所从国外引进
With the “green gold”, the Neem has initially formed a large-scale planting base in Yunnan. The deep processing research and product development have reached the advanced level in China, which has led to the formation of a pollution-free bio-pesticide production system in Yunnan. Melia belongs to the genus Melia tomentosa evergreen trees, suitable for growth in the frost-free dry and hot valley. In 1965, a German scientist discovered in Sudan that the locust disaster destroyed a large number of plants. Only the neem tree was safe after the locust ravages, so the study on the neem was started. After a long period of research, scientists found that the root, trunk, bark, leaves, flowers, fruits and seeds of the neem tree are all “treasure”. Azadirachtin, extracted from fruits, is recognized worldwide as a broad-spectrum, high-efficiency, low-toxicity, easily degradable, residue-free pesticide that can kill over 200 kinds of agriculture, forestry, storage and hygiene pests, Lepidoptera, Coleoptera and Diptera pests have special effects. In 1995, the Chinese Academy of Forestry Insect Resource Insect Research Institute was introduced from abroad
