Abstract:

To investigate the effects of different planting positions in solar greenhouses on the greenhouse environment and the growth of tomato seedlings in arid areas, the tomato cultivar Fenguan 503 was used as the experimental material. A seedling cultivation experiment was conducted at different planting positions in a film-covered semi-arched solar greenhouse oriented east-west in length and north-south in width. Environmental factors inside the greenhouse were monitored using sensors, the variation characteristics of the greenhouse environment were analyzed, the physiological and growth traits of tomato seedlings were measured, and the membership function method was employed to comprehensively evaluate seedling performance at different planting positions. The results showed that temperature and humidity were higher in the central area than in the surrounding areas. Illuminance exhibited a spatial pattern of east > west and south > north. Along the longitudinal direction, substrate temperature in the central area was higher than that on the eastern and western sides, whereas along the transverse direction, substrate temperature was higher in the north than in the south. The western area favored seed germination, seedling growth, and organic matter accumulation, the northern area promoted organic matter accumulation and root development, and the eastern area tended to enhance root growth while suppressing aboveground growth. Comprehensive evaluation of growth traits of tomato seedlings based on the membership function method indicated that seedlings in the northern area achieved the highest score (0.845).

Key words: solar greenhouse, tomato seedling, membership function method, planting position, environmental change
