Experimental Studies About Impacts Of Meteorological Conditions Outside Greenhouse On Conditions Inside Greenhouse

Shouguang Vegetable base located in the North of Shandong Province is one of important vegetable provider in north area of China. But the vegetable production mainly depends on natural sunlight which is largely affected by meteorological conditions. Serial cloudy sky and cold wave in cold half year brings about a greater impact on the quality and yield of vegetable. The study intent is to find the rules about impacts of meteorological conditions outside greenhouse on that inside greenhouse by the experiment and research of meteorological conditions inside greenhouse. On this foundation, the directive forecast and alert of conditions inside greenhouse are put forward. The great results are as follows:(1) The experiment on meteorological conditions in greenhouse was carried out in the north of Shandong province in the winter- spring and autumn-winter seasons 2003 , which observed continuously temperature, intensity of light and relative humidity in the greenhouse, at the same time , meteorological conditions from automatic weather station outside greenhouse are worked.(2) Based on temperature information from experiment in the greenhouse, the characters of temperature are analyzed and the feature of impact of meteorological conditions outside greenhouse on temperature inside greenhouse was probed into. The mostly results are as follows:The rise of the temperature inside greenhouse is quicker than that...
