冀北沙荒地黄柳光合与蒸腾速率日变化特征OA
Diurnal Variation Characteristics of Photosynthesis and Transpiration Rate of Salix gordejevii in Sandy Land of Northern Hebei
[目的]探讨不同坡位黄柳光合与蒸腾的日变化规律,明确不同坡位黄柳光合生产与蒸腾耗水的关系.[方法]以冀北沙荒坡地黄柳沙障为研究对象,采用LI-6400光合测定仪,测定不同坡位黄柳光合、蒸腾及其光合有效辐射、气温、叶面温度的日变化,并以光合、蒸腾速率计算水分利用效率日变化数据.[结果]不同坡位黄柳光合速率(Pn)日变化有差异.下坡黄柳光合日变化为双峰曲线.中坡光合为下降曲线.上坡黄柳光合日变化呈现曲折下降趋势.下坡黄柳光合速率日最大值、日均值分别为…查看全部>>
[Objective] The aim was to reveal the diurnal variation characteristics of photosynthesis and transpiration rate of Salix gordejevii in different slopes, and the relationship between photosynthesis and water consumption for transpiration.[Method] We took the sand barrier by Salix gordejevii in sand slope of northern Hebei as the research object, measured diurnal variation of photosynthesis, transpiration and PAR, atmospheric temperature and leaf surface temp…查看全部>>
