三种草坪草净光合速率和蒸腾速率的日变化特点研究OACSCD
A study on the diurnal variation characteristics of net photosynthesis rate and transpiration rate of three species of turfgrasses
研究了在晴天的条件下,假俭草、细叶结缕草和地毯草净光合速率和蒸腾速率的日变化特点。结果表明:(1)假俭草和细叶结缕草的净光合速率的日变化曲线均为双峰型,而地毯草为三峰型,3种草出现峰值的时间不同,均有明显的"午睡"现象,日平均净光合速率的大小顺序为假俭草>地毯草>细叶结缕草;(2)假俭草和细叶结缕草的蒸腾速率的日变化曲线均为双峰型,而地毯草为单峰型,3种草出现峰值的时间有所差别,"午睡"现象均不明显,日平均蒸腾速率的大小顺序为细叶结缕…查看全部>>
The diurnal variation characteristics of net photosynthesis rate and transpiration rate of Eremochloa ophiuroides, Zoysia tenuifolia and Axonopus compressus in the sunny day were studied. The results showed that the net photosynthesis rate diurnal variation curves of Eremochloa ophiuroides and Zoysia tenuifolia were double-peaked, while the curve of Axono-pus compressus was three-peaked. The peak values of three species of turfgrasses appeared in different t…查看全部>>
