Testing and Analysis on the Spatial and Temporal Distribution of Light Intensity and CO2 Concentration in Solar Greenhouse

Chunhui Zhang et al.

Summary: Greenhouses, as important parts of facility agriculture, can reduce the restrictions on agricultural production imposed by the natural environment and make rational and efficient use of production resources. We conducted long-term, continuous testing and data processing to obtain the overall distribution, variation pattern, and mathematical model of temperature, humidity, light intensity, and CO2 concentration in a heliostat greenhouse in the cold and arid region of northern China. The study provides scientific data for the cultivation of heliostats in the region.

Microclimate and Plant Transpiration of Tomato (Solanum lycopersicum L.) in a Sunken Solar Greenhouse in North China

Li Yang et al.

Summary: The solar greenhouse is a common protected structure for crop production when ambient temperatures are low. In the North China Plain, a sunken solar greenhouse (SSG) is used in winter to take advantage of higher temperatures. A four-season experiment with tomato crops in a commercial SSG found that the temperature inside the SSG could be more than 20 degrees C higher than outside in winter, leading to favorable tomato growth and yields. The sap flow of the crops was influenced by solar radiation, vapor pressure deficit, and temperature, with decoupling coefficient indicating strong radiative influences in the SSG. Crop coefficients varied throughout the seasons, with higher sap flow in winter compared to summer, suggesting the need for irrigation scheduling considerations.

Experimental study on indoor environmental factors of double film solar greenhouse and traditional Chinese greenhouse in cold region

Yerui Liu et al.

Summary: A novel polystyrene foam modular double film solar greenhouse was designed and constructed to create a suitable thermal and humidity environment for crop growth. The results showed that compared to the ordinary single film greenhouse, the double film solar greenhouse effectively improved indoor air, soil temperature, and CO2 concentration, while reducing indoor air and soil humidity. The environmental factors in the double film greenhouse were more stable, providing a theoretical basis for its construction and indoor environment regulation.

The effects of diurnal temperature rise on tomato fruit quality. Can the management of the greenhouse climate mitigate such effects?

Juan M. Ruiz-Nieves et al.

Summary: The study revealed that high temperatures significantly impact the quality of tomatoes, reducing fruit growth duration and fresh/dry matter accumulation rate, while also decreasing the sugar/acid ratio in fruits. Daily temperature fluctuations can alter concentrations of citric acid, malic acid, ascorbate, and carotenoids in fruits.

Assessing the Impact of Higher Levels of CO2 and Temperature and Their Interactions on Tomato (Solanum lycopersicum L.)

Tejaswini C. Rangaswamy et al.

Summary: The experiment showed that elevated CO2 and temperature levels had positive effects on tomato growth and fruit yield, with the best results observed at 700 ppm CO2. However, when combined with elevated temperature, the positive effects were reduced, especially when CO2 exceeded 700 ppm.
