收集新疆落叶松天然分布区 14个种源种子 ,在富蕴林区播种育苗和造林 ,对各种源多个性状进行测定分析。研究结果表明 :( 1)种源间生长物候和适应性无明显差异 ,选择最佳造林种源以生长性状为主。 ( 2 ) 2～ 5龄苗各年度间高生长量秩次相关紧密 ,种源间生长差异的遗传稳定性较好。 ( 3)主分量综合分析 ,该营林生态区重点发展奇台种源的新疆落叶松 ,辅以选择布尔津、阿尔泰、哈巴河和青河种源苗造林
A total of 14 provenances were collected from the natural distribution area of Larix principis-rupprechtii. Seedlings and afforestation were planted in Fuyun forest area, and the traits of various sources were determined and analyzed. The results showed that: (1) There was no significant difference in the phenological and adaptability of the growth between provenances, and the best selection of afforestation provenances was growth traits. (2) The rank of high growth in 2 ~ 5 years old seedlings was closely related to each other, and the genetic stability of the differences in growth among provenances was good. (3) According to the comprehensive analysis of the main components, the Liruensis eco-district focuses on the development of Xinjiang larch in Qidai provenance, supplemented by afforestation of provenances such as Burqin, Altay, Habahe and Qinghai
