Abstract: In order to analysis the effect of low temperature and sparse sunlight on the vegetable growth and effective response in solar greenhouse, the three main types of solar greenhouse were selected to research and statistical analysis in Wuqing district of Tianjin city. The results show that the meteorological conditions of high standard solar greenhouse are better than that of the second-generation solar greenhouse, and that of the simple solar greenhouse are the worst. The lowest temperature in solar greenhouses appears 1 to 2 days later than the outside lowest temperature occurs. The process of low-temperature and sparse sunlight within 3 days has no obvious influence on the production of solar greenhouse, but if the process is more than 4 days, necessary manager measures should be taken to reduce the loss. In addition, in second-generation solar greenhouse, it is risky to grow fruits vegetables in winter, producers can consider to planting leaf vegetables to reduce greenhouse structure investment and management cost.

Key words: solar greenhouse, low temperature and sparse sunlight, variance impact, management measures
