Abstract: 【Objective】 To explore the influence of low energy consumption assembled deep winter production solar greenhouse on indoor soil environment, in the hope of providing data support for the subsequent cultivation and environmental control of the new greenhouse. 【Methods】 In the study, the low energy consumption assembly deep winter production solar greenhouse (new greenhouse) was selected as the test greenhouse, and the ordinary brick wall structure solar greenhouse as the control greenhouse. The difference between the main soil environment of the test greenhouse and the control greenhouse was analyzed, and the method of soil stratification research was used to determine the leading factor. 【Results】 The results showed that the surface soil temperature of the new solar greenhouse increased by 30.1% and-50 to -60 cm by 20.85%, at the night, the soil temperature of the new solar greenhouse was significantly higher than that of the brick wall structure; The water content of different soil depths was compared with the traditional greenhouses, and all were significantly lower; At-10 cm soil depth, the new greenhouse soil water content was reduced by 11%; At a-20 cm soil depth, the new greenhouse soil moisture content was 13.29%; At the-30 cm soil depth, the new greenhouse soil water content was reduced by 2.68%; At a-40 cm soil depth, the new greenhouse soil water content was reduced by 6.63%; At a-50 cm soil depth, the new greenhouse soil water content was reduced by 8.07%; At the-60 cm soil depth, the soil moisture content of the new greenhouse was reduced by 10.74%. Compared with the traditional greenhouse, the total nitrogen content of the deep soil increased by 21.26%, the total soil carbon content increased by 12.07%, and the soil inorganic nitrogen content increased by 19.95%. 【Conclusion】 The new solar greenhouse has higher soil temperature and lower soil humidity during the winter night. At the same time, the new solar greenhouse can control the migration of nitrogen and other elements compared with the traditional solar greenhouse, which can not only better maintain the soil fertility of the cultivated layer, but also reduce the damage and pollution of deep soil and groundwater to a certain extent, and promote the green development of facility agriculture.
