Abstract: The planting effect of eggplant vegetables in the original idle solar greenhouse was used as the experimental material, and the data monitoring and analysis of temperature, humidity, light condition, vegetable yield and benefit in the greenhouse throughout the year were used to study the effect of no heating the solar greenhouse in winter on the planting of eggplant vegetables in the alpine region of Xinjiang, in order to provide reference for the overwinter cultivation of solanum vegetables in high latitude area of Xinjiang.The results showed that the limit low temperature in the greenhouse was about 10.2 ℃,the lowest temperature in the soil greenhouse was 13 ℃,and the highest light intensity was 17.9 klx.While the harvest period of jacket vegetables could be extended from the late October of the same year to the late June of the next year, the yield of eggplant was 40-45 kg·m^-2,the yield of pepper was 30-35 kg·m^-2,the yield of tomato was 45-50 kg·m^-2,and the profit was 40 000-50 000 RMB per 667 m~2.Compared with the early spring and late autumn, it showed a huge advantage.Therefore, energy saving overwinter cultivation of eggplant fruits and vegetables in solar greenhouse could be carried out in the alpine area of 44°18′55″-44°53′00″N.
