温室、大棚等保护地设施是相对密闭的蔬菜作物栽培场所，保护地内光照、温度、湿度、二氧化碳浓度等与露地栽培有明显差异。在保护地栽培条件下的作物，长期处于高温、高湿环境，特别是室内外气体交换受到限制，比露地栽培光照强度低。二氧化碳浓度在白天由于植物的光合作...
Greenhouses, greenhouses and other protected facilities are relatively confined vegetable crop cultivation sites, protected areas of light, temperature, humidity, carbon dioxide concentration and open-field cultivation were significantly different. Under protected cultivation conditions, crops are exposed to high temperature and high humidity for a long period of time, especially for indoor and outdoor gas exchange, which is lower than that for open field cultivation. Carbon dioxide concentration during the day due to plant photosynthesis ...
