Abstract: In order to get the characteristics and regulation of environmental factors and the interaction of inside-outside environmental factors in greenhouse in the winter, the greenhouse intelligent control system was used to record and store the data of indoor co2 concentration, soil temperature, soil moisture, indoor and outdoor temperature, humidity, light. the results showed that the interaction of environmental factors was close; except soil temperature and soil water ,environmental factors had a significant correlation between each other; temperature and light of inside-outside greenhouse had a significant positive correlation between each other, curves were irregular "n" shape, humidity of inside-outside greenhouse and co2 concentration of inside greenhouse had a significant negative correlation with them, curves were irregular "u" shape; soil moisture had a smaller diurnal variation, it had a close interaction with soil temperature; environmental factors of inside-outside greenhouse had a close interaction, the temperature change of inside greenhouse was the results of the combined effect of temperature and light conditions of outside greenhouse, the temperature of outside greenhouse has the greatest effect on the soil temperature change , light of inside greenhouse, had a close interaction with light of outside greenhouse.
