Abstract:
Base on the data of temperature and relative humidity inside of the middle of the four arch plastid greenhouse of non-heating at 1.5m in height during the period of December 1999 to August 2002. The quantitative relation equations are developed for average temperature,maximum temperature,minimum temperature,average relative humidity of the whole day between the inside and outside weather elements under different weather conditions(sunny,cloudy,overcast) in different seasons by means of the step-regression method. The technical reference would be provided to choose vegetable variety,plant standardized vegetables and free-pollution vegetable production and prevent disease and insect in the microclimate field.
