查询词典 par-three

The CO2 uptake rate of plants is affected by the plant species and environmental conditions such as photosynthetically active radiation, temperature, water and nutrient contents. PAR is the most immediate environmental control on photosynthesis while air temperature affects both photorespiration and dark respiration. In the natural condition, PAR and temperature play an important role in net CO2 uptake. The effects of PAR and air temperature on the CO2 uptake of Pterocarpus macrocarpus grown in a natural habitat were studied in the present work. Due to many uncontrollable factors, a simple rectangular hyperbola could not represent the measured data. The data were divided into groups of 2℃ intervals; CO2 uptake in each group may then be related to PAR by a rectangular hyperbola function. Using the obtained functions, the effect of PAR was removed from the original data.

用涡度相关法对亚热带红壤丘陵区人工针叶林的二氧化碳、水、热通量进行了观测，重点分析了23m、39m两层高度的观测结果，同时把观测期分为春季和冬季两个不同时间段作了对比：结果表明，不管冬季还是春季，39m高度所测的总通量值和夜间通量值都要小于23m的观测值，这种通量差别表明：23m高度的观测结果更接近当地生态系统与大气之间的通量交换值，在此种生态类型条件下用涡度相关法测碳通量时，在23m、39m两层高度之间仍然存在大气平流现象；该试验区植被在冬季仍然可以进行光合作用，而且光合作用所吸收的CO2大于呼吸作用所排放的CO2，因此该种生态系统在冬季仍表现为碳汇；春季的碳通量值为冬季的2倍以上。

The geometry of canopy and interception of photosynthetically active radiation were measured.

通过实测和理论计算，结果表明：高原地区冬小麦叶片比平原地区的更趋于直立，具有比平原地区低的消光系数，能够容纳较大的绿叶面积和有效穗数；当冠层对PAR的截获率趋于饱和时，高原地区麦田可容纳的最大绿叶面积可达8.6，是平原地区的1.4倍左右；开花到成熟期间的叶日积大约可达平原地区的2倍，绿叶面积持续时间长；整个生长季期间，高原地区的PAR总量是平原地区的1.7倍，单位绿叶面积所截获的PAR是平原地区的1.3倍，又由于其叶片的趋于直立，故从上到下叶片受光比平原地区更均匀和充分，群体光合潜力高，对PAR的利用率更高。
