| [photosynthetic rate, transpiration rate, and water use efficiency of cotton canopy in oasis edge of linze]. | the measurement system of li-8100 carbon flux and the modified assimilation chamber were used to study the photosynthetic characteristics of cotton (gossypium hirsutum l.) canopy in the oasis edge region in middle reach of heihe river basin, mid hexi corridor of gansu. at the experimental site, soil respiration and evaporation rates were significantly higher in late june than in early august, and the diurnal variation of canopy photosynthetic rate showed single-peak type. the photosynthetic rate ... | 2010 | 20873616 |
