STUDY ON THE VARIATION OF THERMAL ENVIRONMENT AND PHOTOSYNTHESIS CHARACTERISTICS OF STRAWBERRY IN A SOLAR GREENHOUSE
The sunken solar greenhouse is suitable for the development of vertical planting, which results in higher yield. In order to investigate the effect of temperature on photosynthesis of plants, an experimental study was conducted on the temperature and photosynthesis of strawberry plants at different heights in the sunken solar greenhouse. The study showed that when the indoor temperature was higher than 25.5℃, the photosynthesis of plants was inhibited; the transpiration rate decreased by 3.89 and photosynthesis rate decreased by 3.95 when the air temperature increased from 25.5℃ to 33.3℃ and then decreased to 25.4℃ at a height of 1.8m from the indoor floor; there were temperature differences in the vertical direction between the indoor temperatures of the sunken heliostat. The maximum temperatures at 0 m, 0.6 m, 1.0 m, 1.4 m, and 1.8 m height were 20.6°C, 24.1°C, 25.4°C, 25.4°C, 33, and 3°C, respectively, and different temperatures would have different photosynthetic characteristics of plants. This study can provide basic support for greenhouse regulation.
