| 摘 要： | 希蒙德木是一种重要的生态经济型树种,金沙江干热河谷地区适宜种植.研究表明:微生境造林是解决金沙江干热河谷地区希蒙德木造林的有效途径之一,直播造林以雨季末期(秋季)较佳,植苗造林旱季优于雨季;希蒙德木单株、各器官生物量均随年龄增加而增加,2年生时干、枝、叶和根生物量增长最快,植株花生物量4年生时开始大幅度增长;各器官生物量分配随树龄变化而变化. |

| Abstract: | Simmondsia chinensis is a tree species with important ecological and economic value,which fits to be planted in the dry-hot valley of Jinshajiang River.The conclusions were drawn from different experiments as follows: Making micro-habitat was an effective way for planting Simmondsia chinensis successfully in this area.Planting by directive sowing should be carried out by the end of rainy season(in autumn),while sapling planting should be done in the dry season.The biomass of individual plant and the biomass of each organ increased along with the age increment.The maximum increments of biomasses in stem,branch,leaf and root system took place in 2-year-old,but flower biomass increased quickly at the 4th year.Biomass allocation in different organs varied along with the age of the plants. |
| Keywords: | Simmondsia chinensis afforestation method biomass dry-hot valley Jinshajiang River |
