摘要
为探索连栋塑料大棚内气候因子的变化特征,对温室内垂直方向和水平方向的气温和相对湿度进行了连续的观测,结果表明,不同天气条件下温室内平均气温和平均相对湿度具有明显的变化特征。番茄叶片净光合速率的梯度分布特征是上部最大,中下部则迅速下降。
In order to clarify how the physical properties of climatic factors change in the malti-span plastic greenhouse,a study was undertaken,the temperature and humidity of different height and horizontal was long- term measured.The result showed that the average temperature and humidity had obvious features in any weather condition.The value of photosynthesis rate of tomato is the greatest at the top of hedge,with quickly decreasing at middle and lower part.
