Abstract:
In order to study the threshold of time for the uncovering insulation of the solar greenhouse in winter，the time of the insulation was taken as the control (CK) based on the experience of the farmers.Based on the sunrise and sunset time，the designed insulation was taken as the treatment (H).The temperature and lighting environment inside and outside the solar greenhouse were recorded.The growth of tomato leaf,and stem fruit were compared.The results showed that H treatment was 1.19 hours longer than CK in sunny，and H treatment was 1.49 hours longer than CK in cloudy.Compared with CK，H treatment made the plant height and stem diameter of cherry tomato higher than CK.H treatment made the net photosynthetic rate，transpiration rate and intercellular carbon dioxide concentration of cherry tomato higher than CK.H treatment made the content of cherry tomato fruit vitamin C，soluble sugar，soluble solids and sugar acid were higher than CK.H treatment had a significant effect on the total number of fruit set，single plant yield and total yield of cherry tomato，and had a significant effect on the yield per unit area.The impact was not significant on single fruit weight.The results of this experiment had certain guiding significance for the management of Ningxia summer greenhouse from the end of October to the beginning of March.
