摘要
本文根据塑料大棚内外空气温、湿度及大棚通风口处风的观测资料,发现了棚内空气温、湿度时空分布的若干特点,尤其是闭膜条件下,大棚的保温效应和保湿效应的相对强弱在正午前有一交替时刻.并找出了棚内外温、湿度差与通风口处通风量之间的基本关系.
Based on the data of air temperature and humidity obtained from inside and outside of plastic greenhouse as well as of wind on the opening of the greenhouse, some properties were found of the time and space distribution of air temperature and humidity, especially, the inequality of the temperature-preserving and humidity-preserving effects in the closed greenhouse except a certain time before noon when both effects are equal. In addition, a general relationship was discovered between the quantity of ventilation on the opening of the greenhouse and the temperature and humidity differences between inside and outside of the greenhouse.
