Abstract: In order to explore the difference in lighting performance between the new solar greenhouse and the mainstream greenhouse in Heilongjiang Area, the solar energy interception and light intensity of the new solar greenhouse（W1） and the mainstream greenhouse（W2） in different areas and vertical heights in winter were studied by comparative analysis method.The results showed that the solar energy interception of W1 greenhouse was higher than that of W2 greenhouse during the same time period, and the increase rate was about 14%-25%. The external light radiation area of W1 greenhouse was lower than that of W2 greenhouse, which was about 6.88% lower than that of W2 greenhouse.The light intensity of W1 greenhouse reached up to 34 752 lx, while the light intensity of W2 greenhouse was 28 021 lx, and the light intensity of W1 greenhouse was 1.24 times that of W2 greenhouse. The average light intensity of W1 greenhouse was 20 376 lx, which is 1.29 times that of W2 greenhouse light intensity average of 15 845 lx. The light intensity contrast in different time periods was that, the W1 was greater than W2, and the light intensity of W1 greenhouse was increased by 24%-34% in different time periods compared with W2 greenhouse, so the light environment was better than that of W2 greenhouse.In terms of vertical height, the greenhouse light intensity first rises and then decreases, except for the near ground height, the other heights of W1 greenhouse light are higher than W2 greenhouse, indicating that for crops with a height of 0.5 m, the W1 greenhouse light environment is better than that of W2 greenhouse.W1 greenhouse solar interception amount is large, light radiation area is small, light energy utilization rate is high, and the light radiation in different spaces in the greenhouse is more uniform and consistent, and there are few shading or weak light areas produced in winter. Therefore, the lighting performance of W1 greenhouse is better than that of W2 greenhouse.
