摘　　要：利用LI-6400便携式光合测定系统分析测定了辽宁阜新原种猪场6种绿化树种的生理生态指标,进而对其固碳释氧能力进行评价。结果表明:不同月份,6种绿化树种的净光合速率日变化曲线明显不同,主要为双峰型,第一个峰值多出现在上午7:00-9:00左右,第二个峰值在14:00-16:00之间,中午时均出现明显的光合午休现象。银中杨和小叶杨净光合速率分别在6、7月份达到最高值,呈单峰曲线变化;南果梨和苹果梨在8月份明显降低,随后升高,呈双峰曲线变化;白丁香和紫丁香在6月份有明显降低,也呈双峰曲线变化。6、7、8三个月份6种绿化树种的固碳释氧能力较强,9月份次之,5月份最弱。苹果梨的固碳释氧能力最高,其次是白丁香、南果梨、小叶杨和银中杨,而紫丁香的固碳释氧能力最差。苹果梨、白丁香及小叶杨是合适的绿化植物,适宜于广泛推广,大面积种植。图5,参23。The physiological indices of six greening tree species on a large-scale Pig Farm of Fuxin city were measured by the LI-6400 portable photosynthesis system,and their carbon-fixation and oxygen-release potentials were evaluated.The results indicated that the daily curves of the net photosynthetic rates of the six tree species were mainly a double-peak type,with the first peak appearing between 7：00-9：00,the second one between 14：00-16：00,and an apparent photosynthetic siesta phenomenon at noon.The net photosynthetic rates of Populus alba berolinensis and Populus simonii Car seasonally varied as single-peak curve and arrived at the peak in June and July,respectively.And that of Pyrus ussuriensis Miaxim.fand Pyrus ussuriensis Maxim.varied as a double-peak curve,with a valley August.The net photosynthetic rates of Passer montanus saturatus Stejneger and Syringa oblata Lindl also seasonally varied as a double-peaks curve,with a significant reduction in June.The potentials of the six tree species on fixing carbon and releasing oxygen were high in the months of June,July and August,weaker in September,and weakest in May.The order of their potentials on fixing carbon and releasing oxygen was Pyrus ussuriensis Miaxim.f Passer montanus saturatus Stejneger Pyrus ussuriensis Maxim. Populus simonii Carr. Populus alba berolinensis Syringa oblata Lindl.Pyrus ussuriensis Miaxim.f.,Passer montanus saturatus Stejneger and Populus simonii Carr.were suitable greening tree species for widely planting on the large-scale pig farm.
