1995年以来,中国引进印楝属2个种24个种源。本文概述印楝种植及其产品开发的相关研究,分析引种印楝子代的形态特征、物候、生长规律、传花授粉和种子产量等性状的变异。结果表明,印楝大多数种源在云南省具热带气候特征的干热河谷地区能正常开花结实和生长。开展了引种印楝的区划,提出了优良种源和优良无性系选择的标准,探讨了印楝农药原料林建造的技术措施降低印楝杀虫剂生产成本的对策。
Since 1995, China has introduced 24 species of two species of Neem. This article summarizes the related research on the development of neem plantation and its products, and analyzes the morphological characteristics, phenology, growth pattern, pollination and yield variation of introduced neem progenies. The results showed that most of the provenances of Azadirachta indica were able to flower, grow and grow normally in the dry-hot valley with tropical climatic features in Yunnan Province. The introduction of neem zoning was introduced and the criteria for selecting elite provenances and elite clones were put forward. The countermeasures to reduce the production cost of neem insecticides were discussed.
