Objectives
To find out the difference of photosynthesis between treatment and non-treatment of Lime-Bordeaux mixture in 3 year old ginseng
Materials and Methods ◦ Materials
1. Plant: 4 year old ginseng cultivated as standard shading type. 2. Lime Bordeaux mixture : 8-8 type
Type Copper sulfate(g) Lime(g) Water(L)
8-8 8 8 1
◦ Methods
1. Application Time and Interval 가. Start Time of Spray : July 1. 나. Interval of Spray : 15 day
다. Chemical Control before spraying Lime Bordeaux mixture 2. Photosynthesis : Potable photosynthesis system (LI-COR, LI-6400) Results
1. Photosynthesis in the plot of spraying Lime-Bordeaux mixture has been decreased until six days compared with the control plot, but after 7 days, photosynthesis of the two plot has no difference.
2. In high temperature condition, photosynthesis in the plot of Lime-Bordeaux mixture was a little higher than that in the control plot.
