In the paper,9 different substrate formula for Aleurites montana container seedlings were compared in State-owned Nurs-ery of Jianyang,Nanping during the years of 2019 and 2020,in order to examine the effects of different substrate formula on the pho-tosynthesis efficiency of Aleurites montana seedlings.The results showed that in P5 substrate treatment(50％peat+25％yellow soil+25％hull),net photosynthetic rate,transpiration rate,and water utilization efficiency of Aleurites montana seedlings reached the highest.In P3 treatment(30％peat+50％yellow soil+20％hull),the stomatal conductance of seedlings was the highest and significantly higher than CK.P4 treatment(60％peat+20％yellow soil+20％hull)witnessed the peaks in intercellular carbon dioxide concentration and Fv/Fm.According to the comprehensive characteristics,the two kinds of substrate formula of 50％peat+25％yellow soil+25％hull and 60％peat+20％yellow soil+20％hull were the most beneficial to improving the photosyn-thetic capacity of Aleurites montana container seedlings.This studycan provide relevant data and theoretical reference for the culti-vation technology optimization in the application of Aleurites montana container seedling production.
