Abstract: Agricultural Internet of Things technology is an important means to realize intelligent agricultural production.Based on the agricultural Internet of Things technology and tomato production experience in Zhaoxian county, Shijiazhuang, the environmental control technology of northern solar greenhouse based on temperature management was developed.The daytime environmental management and control modes were temperature and humidity control mode, temperature and humidity control mode,heat preservation and light supplement mode,while the night environmental management and control modes were day-night temperature difference increasing mode and day-night temperature difference decreasing mode.The environmental management and control methods in special weather were briefly described,which provided a reference for realizing intelligent control of tomato production in solar greenhouse in autumn and winter.
