慈溪地区日光温室气温变化规律

为了探讨冬春季日光温室内气温的变化规律，合理调控日光温室气温，提高作物产量与品质，利用浙江省慈溪市气象局设施农业基地的标准塑料日光温室内外气温对比观测试验数据，对不同天气类型下温室内外气温变化规律进行分析。结果表明：（1）慈溪地区日光温室室内日平均气温均高于室外，温室内外气温总体变化趋势一致，温室内外气温差的日变化主要受太阳辐射影响；（2）室内气温不同天气类型日变化均呈“单峰”型，白天气温变化速度总体表现为：晴天＞多云＞阴天＞雨天，夜间各天气类型气温变化均较平稳；（3）不同天气类型下室内外气温的关系显著，两者相关性表现为：雨天>阴天>多云>晴天。

Change Laws of Air Temperature in Solar Greenhouse in Cixi

To investigate the variation of the temperature in winter and spring inside sunlight greenhouse in Cixi, and to appropriately adjust the solar greenhouse temperature as well as to increase the crop yield and quality, the author analyzed the solar greenhouse inside and outside temperature with different weather types based on the collected data of single standard plastic solar greenhouse in agriculture base of bureau of meteorology in Cixi, Zhejiang. The results showed that: (1) Cixi solar greenhouse indoor average daily temperature was higher than that of the outdoor, the overall trend of greenhouse inside and outside temperatures was same, the daily changes of greenhouse internal and external air temperature were affected by the solar radiation; (2) Type of indoor temperature diurnal variation of different weather types showed an unimodal daytime temperatures change speed, the overall air temperature change followed sunny>clouds>cloudy>rainy, and the nigh temperature change was stable at different weather types; (3) The relationship between indoor and outdoor air temperature was notable, and the correlation was as rainy day>cloudy>cloudy>sunny.The results showed that: (1) Cixi solar greenhouse indoor average daily temperature is higher than that of the outdoor, the overall trend of greenhouse inside and outside temperatures is same, the daily changes of greenhouse internal and external air temperature were affected by the solar radiation ; (2) type of indoor temperature diurnal variation of different weather types showed a unimodal daytime temperatures change speed, the overall air temperature change followed sunny> Clouds> cloudy> rainy, and the nigh temperature change is stable at different weather types; (3) The relationship between indoor and outdoor air temperature is notable, and the correlation is as rainy day>cloudy>cloudy >sunny.
