以新疆常见的抗旱树种梭梭、柽柳、沙拐枣和经济树种枸杞、李树、杨树为研究材料,用英国PP system公司产CIRAS-1光合作用仪,以不同的光强测定以上6种树种的光合作用速率,以观测数据为基础,对6种树种的固碳能力分抗旱树种和经济树种两组进行了分析比较。结果表明,两组树种的固碳能力由高到低分别为柽柳>梭梭>沙拐枣和杨树>枸杞>李树。同时结合水分和土壤条件,对树种的筛选提出建议。
The common tree species of Haloxylon ammodendron, Tamarix chinensis, Calligonum pekinesis, and economic tree species Lycium barbarum, Populus trichocarpa and Poplar were selected as the research materials. The CIRAS-1 photosynthesis apparatus produced by the British PP system company was used to measure the above six kinds of light intensity Based on the observed data, the photosynthetic rate of tree species was analyzed and compared between the two species of drought-resistant tree species and economic tree species. The results showed that the highest carbon sequestration of the two tree species was Tamarix chinensis> Haloxylon ammodendron> Calligonum mongolica> Populus> Lycium> Lycium barbarum. At the same time, combining water and soil conditions, we put forward suggestions for the screening of tree species.
