In order to investigate the adaptability and growth status of different feed mulberry varieties in Yulin area,this article used Li-6400 portable photosynthesis analyzer to measure and compare the photosynthetic characteristics of five feed mulberry varieties,including Fengchi No.1,Fengchi No.2,Wubaosang,Jingsang,and Xuanqijiuer,and conducted correlation analysis on different photosynthetic indicators.The results suggest that there were significant differences in the photosynthetic characteristics of different mulberry varieties,among which the intercellular CO2 mole fraction of Fengchi No.2 was significantly higher than that of other varieties,indicating that Fengchi No.2 had a higher photosynthetic rate;Xuanqijiuer showed a high net photosynthetic rate and low stomatal conductance,indicating its strong adaptability and high light utilization efficiency.The above results can provide reference for the selection of feed mulberry and optimization of planting management.
