Abstract:

In order to screen out suitable aperture and cover mode of hail net for dryland tomato in Huguan County, Changzhi City, Shanxi Province, hail suppression nets with apertures of 5 mm×5 mm, 8 mm×8 mm and 10 mm×10 mm were used to compare the effects of different treatments (setting up hail net only at the top, all around, and no hail net on) on temperature, humidity, carbon dioxide concentration, light intensity, soil moisture content, plant height, stem diameter, maximum spreading degree, yield and quality. The results showed that appropriately setting up hail net could affect the microenvironment in the hail net, make the tomato plants stronger, and improve the yield and quality. Among them, the hail net with aperture of 8 mm×8 mm and covering only the top was the best way for tomato growth in dryland.
