Abstract: Based on the former study of Zinc nutrition in Soybean, a primary study on the Zinc physiology was carried out. The results showed; Within the low Zn concentration range of 0 -0.3ppm,Zinc appeared helpful to plant height,numbers of nods, branchs,green leaves and pods,roots volume and nodule number.The photosynthesis intensity of leaves from Zn deficient plant was 21.9% lower than that of normal leaves.The respiration intensity of normal leaves was 95.9% higher than that of Zn deficient leaves. The chlorophyll content, carbonic anhydrase and activity of nitrate reductasc (NR) had a positive relation with Zn concentration. The order of the NR activity from high to low was. root, leaf-stalk, upper stem, middle stein, and lower stem
