【摘要】 各种作物的光合率由于受塑料大棚的影响,其特性各不相同,包括其日变化现象及其与光照度的关系,且温度也影响着作物的光合率。塑料大棚隔绝了棚内与棚外的气流交换,造成棚内高温高湿的小气候效应。本文主要研究塑料大棚内辣椒叶片的光合特征,通过平行对比观测,对大棚内外不同的光强、温度两项环境因子对辣椒叶片的光合作用产生的影响进行粗浅的探讨。更多还原

【Abstract】 This paper presents the study of photosynthesis characteristics of hot pepper’s leaves in the plastic greenhouse. Because the plastic greenhouse prevents the changes of air current, there is a limit scope climate effects in the plastic greenhouse. By the way of observing photometric intensity and temperature inside and outside of the plastic greenhouse,we can find the photosynthesis of hot pepper’ s leaves is influenced by photometric intensity and temperature.更多还原
