Abstract:
With 3-year-old ginseng as test material，shade shed set up four kinds of treatments (P1M1,arch shed covered with blue films；P1M2,arch shed covered with yellow films；P2M1,trapezoidal shed covered with blue films；P2M2,trapezoidal shed covered with yellow films)，using Li-6400 portable photosynthesis system measured photosynthetic parameters of ginseng leaves at different shade shelters,effect of different shade shelters on gas exchange characteristics of farmland ginseng leaf at flowering was studied，in order to determine the best way to shaded for farmland ginseng.The results showed that farmland ginseng leaf net photosynthetic rate at flowering was the period of high stability，net photosynthetic rate of farmland ginseng was significantly different under different shade shelters，showing P1M1 processing net photosynthetic rate was the highest，followed by P2M1，the lowest was P2M2.Transpiration rate，water use efficiency and apparent leaf mesophyll conductance were the same with net photosynthetic rate.The conclusion showed the best method for farmland ginseng growth was arched awning covered under blue films，which had strong photosynthesis and metabolism，was the best way for cultivation.
