Abstract: The meteorological conditions during the period of industrial tomato seedling cultivation in Xinjiang were studied to provide the meteorological basis for industrial tomato （Lycopersicon esculentum Mill.） seedling cultivation in greenhouse. Microclimate observatory stations in the shed of industrial tomato seedling in Hejing, Yanqi and Bohu of Bazhou in Xinjiang province were installed, and the leaf age and the physiological and ecological indexes of industrial tomato seedling was observed to summarize the light, temperature and water requirements from sowing to transplanting. The results showed that the tomato seedling shed standard were reached when the industrial tomato had grown 5 true leaves, achieved 45 to 52 days seedling age, and reached 12 cm to 15 cm of plant height. It took 8 to 10 days for tomato to grow from sowing to emergence. Time for one leaf to grow was 2 to 15 days. The greenhouse temperature was between 3.8 to 38.8 ℃ with the average temperature being 14.7 ℃ during the entire tomato growth period. The greenhouse temperature was between 5.8 to 36.6 ℃ with the average temperature of 11.8 to 22.9 ℃ during the first to fifth true leave growth period. The accumulated temperature of the whole seedling stage was 805.8 to 955.9 ℃.
