Abstract: According to the eco-meteorological data observed for many years in Chinese solar greenhouses,the disaster index and grades of low temperature and sparse sunlight for cucumber and tomato in the greenhouse were summarized.The weather disaster early warning system integrated with remote monitoring technology was established for low temperature and sparse sunlight in the greenhouse,and preliminarily validated and applied in greenhouse vegetable production in Hebei Province.The results showed that this system could provide dynamically early prediction for warning the range and intensity of low temperature and sparse sunlight occurring in the greenhouse.At the same time,automatically created MS word document format for information service could proved wide applicable perspective in disaster diagnosis and forecast.

Key words: Chinese solar greenhouse, Chinese solar greenhouse, Low temperature and sparse sunlight, Greenhouse control, Remote diagnosis, Monitoring and warning
