Abstract: In order to explore the optimal planting time for tomato, and propose the technical measures for tomato yield. The experiments of 12 planting dates were performed from February 27, 2017 to January 27, 2018 to observe environmental factors,growth period and corresponding production of tomato in each growth period.Then,we further analyzed the correlation between environmental factors and yield at different growth stage. The results showed that:the whole growth period of tomato planted on April 27,2017 and May 27,2017 was the shortest,105 d and it was shortened by 41.67% compared with the whole growth period of tomato planted on September 27,2017. The mean maximum temperature, mean minimum temperature, mean temperature and daytime mean temperature, mean temperature at night,mean temperature difference, mean soil temperature, mean light intensity and mean relative humidity are key environmental factors for the growth period of tomato. The mean minimum temperature and mean temperature were significantly and negatively correlated with tomato yield from planting dates to blossoming dates, with correlation coefficients of -0.76, respectively. Mean temperature difference, mean light intensity, mean maximum temperature and mean temperature,respectively,were significantly and positively correlated with tomato yield from harvesting dates to uprooting dates, with correlation coefficients of 0.90, 0.81, 0.75 and 0.71, respectively.So temperature is a key environmental factor affecting tomato yield. According to the comparison of the yields of each treatment, the highest production in spring appeared in the planting dates of January 27, 2018,which was 127 437.45 kg/ha, followed by December 27,2017 and February 27, 2017 which were 117 674.25,115 912.95 kg/ha respectively. The planting dates of autumn sorghum was the highest on August 27, 2017 which was 62 007.90 kg/ha, followed by September 27,2017,which was 54 532.95 kg/ha. This indicates that the best planting dates of spring tomato in Ningxia greenhouse is from late December of the first year to early February of the second year, which environmental factors are conducive to the formation of tomato yield. The best planting dates of autumn tomato is from late August to early September. During this growth period, the yield of tomato can be increased by reducing the temperature during the planting dates-blossoming dates and increasing the temperature and light intensity during from harvesting dates to uprooting dates.
