日光温室内小气候环境各因子间量化关系研究

掌握日光温室内小气候环境各因子之间的定量关系，对于有效调控温室内小气候的平衡，促进蔬菜健壮生长有着积极的意义。以历年日光温室内小气候监测数据为基础，研究不同季节温室内温度、湿度、接受到的太阳辐射等各因子之间的量化关系。结果表明，日光温室内日最高气温、日最小相对湿度、接受到的日最大太阳辐射三者之间均有较高的相关性，在冬季相关性最好，秋季次之，春季相关性较差。在秋季和春季，要使温室内日最高气温达到20℃，则温室内接受到的日最大太阳辐射需要在100 W/m²以上，而在冬季则需要在250 W/m²以上；接受到的日最大太阳辐射在250 W/m²以下时，温室内日最高气温在10℃以下的几率为9%。在冬季，温室内日最高气温在20℃以下，同时日最小相对湿度在90%以上所占比例为20%，在秋季和春季，温室内接受到的日最大太阳辐射分别在420 W/m²和500 W/m²以上时，温室内日最小空气相对湿度就有可能下降到40%以下。

The Quantification Relations Study Between Various Microclimate Environment Factors in Sunlight Greenhouse

To understand the quantitative relations between various microclimate environment factors in the sunlight greenhouse has positive significance to effectively regulate the balance of microclimate in greenhouse and promote the vegetables＇ vigorous and healthy growth. Based on the microclimate monitoring data in the sunlight greenhouse over the years, the author studied the quantification relations between the temperature and humidity, solar radiation accepted in the greenhouse for different seasons. The results showed that there was high relevance between the maximum temperature, the smallest relative humidity and the accepted solar radiation, the best relevance was in winter, followed by that in autumn and relevance in spring was the worst. In autumn and spring, if the daily maximum temperature was required as 20℃ in the greenhouse, the daily accepted solar radiation should reach 100 W/m2 above, but in the winter, it needs to be 250 W/m2 above. When the maximum daily accepted solar radiation was below 250 W/m2, the probability of the daily maximum temperature below 10℃ was 9% in the greenhouse. In winter, the daily maximum temperature below 20℃ while the daily relative humidity over 90% accounted for the proportion of 20% in the greenhouse. In autumn and spring, when the maximum daily accepted solar radiation was 420 W/m2 and 500 W/m2 above respectively,the daily minimum air relative humidity might drop to below 40% in the greenhouse.
