Diurnal variation of photosynthesis of Phyllostachys aurea grown inside and outside greenhouse and its influential factors in summer
摘要
Abstract
In this paper,we explored the diumal variation of photosynthesis of Phyllostachys aurea grown inside greenhouse,and clarified the difference of light intensity,temperature,humidity,CO2 concentration and other factors both inside and outside greenhouse,in order to provide reasonable cultivation methods and theoretical basis for facility cultivation of Phyllostachys aurea.The study was carried out in July,and the curve of the photosynthesis rate of Phyllostachys aurea was shown as a two-peak pattern on the conditions of both cooling measures and no cooling measures inside greenhouse,however,the characteristics of the curve of the photosynthesis rate of Phyllostachys aurea was not obvious in the open air.Average daily Pn inside greenhouse with cooling measure＞Pn inside greenhouse without cooling measure＞Pn in the open-air.Average daily,HR inside greenhouse＞HR in the open-air,PAR inside greenhouse＜PAR in the open-air,CO2 concentration inside greenhouse＜CO2 concentration in the open-air.Therefore,the cooling and moistening measures should be taken to improve photosynthetic efficiency of Phyllostachys aurea inside the greenhouse.Besides,high-temperature and high light intensity are the main reasons for its phenomenon of “midday nap” in summer.关键词
