收集新疆落叶松 ( Larix sibirica)全分布区 1 5个种源 ,在该树种主要生态营林区—布尔津林场 ,开展 2次年度重复的育苗、造林试验。结果表明 :( 1 )种源间当年苗抽梢率、越冬保苗率、造林成活率及生长量存在显著差异 ;( 2 )种源间各项技术指标随地理因子呈现不连续变异 ,总的趋势为经度、海拔的影响大于纬度。综合考虑认为 :该营林区选择布尔津、和丰、哈巴河等林场的种源育苗、造林较为适宜。
Fifteen provenances were collected from the Larix sibirica distribution area in Xinjiang. Two annual seedling and afforestation experiments were conducted in the Buerjin Forest Farm, the main ecological management area of the tree species. The results showed that: (1) There were significant differences in seedling shoot rate, winter seedling protection rate, afforestation survival rate and growth rate between provenances; (2) The technical indicators of different provenances showed discontinuous variation with geographical factors, the general trend For longitude, altitude is greater than latitude. Taking into account that: the forest area to choose Burqin, Hefeng, Habahe and other forest provenance breeding, afforestation more appropriate.
