石碌含笑光合及固碳特性
|
摘要
本文以石碌含笑二年生嫁接苗为研究对象,采用LI-6400便携式光合仪对其光合参数特征进行测定分析,并对其固碳释氧量进行估算,综合评价其适应性及生态效应。结果表明:石碌含笑的四季净光合速率(Pn)日变化并非呈现单一的双峰。1月、4月、7月的变化曲线为双峰型,10月为单峰型。石碌含笑不同月份Pn日均值由大到小依次为:10月>7月>4月>1月。其生长旺盛期在10月,石碌含笑在大气温度较低和光强较弱的秋季反而有更高的光合速率。石碌含笑的光补偿点低而光饱和点较高,说明能够适应不同的光照环境,在强光环境和弱光环境都有较强的光能利用能力。石碌含笑全年日均净固碳量为10.07 g/(m~2·d),拥有较强固碳能力。石碌含笑对强弱光均有较强的利用能力,在华南地区炎热气候条件下也具有"午休"的适应性自我调节机制,并且拥有较强的碳汇能力,兼具良好的景观效益与优良的生态效益,因此适合在华南地区推广种植。
In this study, two-year-old Michelia shiluensis grafting seedlings were studied. In order to evaluate the adaptation and its ecological effect of M. shiluensis, a LI-6400 portable photosynthetic system was used to measure the photosynthetic characteristics and estimate their carbon sequestration. The results showed that the variations of net photosynthetic rate(Pn) in M. shiluensis did not present a single bimodal in four seasons of a year. The change curve of January, April and July was bimodal, but that in October is unimodal. In different months, Pn changed from the largest to the smallest in the following order: October, July, April and January. M. shiluensis grew fastest in October. There was a higher photosynthetic rate in autumn with lower atmospheric temperature and weaker light intensity. The light compensation point was low and light saturation point was high, indicating that M. shiluensis could be adapted to different lighting environments. The annual average daily net solid carbon content was 10.07 g/(m~2·d), with strong carbon sequestration ability. The results indicate that M. shiluensis can be adapted to both the strong and weak lighting. Under hot weather conditions in South China, it also has the adaptive self-regulation mechanism of "siesta", and had strong carbon sink ability, with good landscape efficiency and excellent ecological benefits, and it is suitable for planting in southern China.
