Abstract: 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.
