Title: Photosynthetic Characteristics of Six Green Plants at Spring Time in Pig Farm Area
Abstract: In order to study the photosynthetic characteristics of Xiao yang tree,Populus alba,Apple pear,An fruit pear,Passer montanus saturatus Stejneger,Syringa oblata Lindl and provide theoretical support for their scientific planting,the diurnal variation of net photosynthetic rate,transpiration rate,stomata conductance and intercellular carbon dioxide concentration were measured by Li-6400 portable photosynthesis instrument.The results showed that the diurnal courses of photosynthesis in Xiao yang tree,Populus alba,Apple pear and An fruit pear were double peaks,but the others were single peak.The order of photosynthesis rate was Apple pearAn fruit pearPasser montanus saturatus StejnegerPopulus albaXiao yang miaoSyringa oblata Lindl.And the sequence of transpiration rate was Apple pearAn fruit pearPasser montanus saturatus StejnegerPopulus albaXiao yang treeSyringa oblata Lindl.The transpiration rate of Xiao yang tree,Apple pear,An fruit pear and Syringa oblata Lindl were double peaked,Passer montanus saturatus Stejneger and Populus alba were single peaked.The intercellular carbon dioxide concentration of the six green plants was changed greatly.
