Abstract: In order to support good growth for airplant, two distinct forms special fertilizer（15:5:30, 17:8:22）were used in different concentrations such as 500 times/dilute, 1000 times/dilute, 2000 times/dilute, 3000 times/dilute, 4000 times/dilute and control group. Percentage of individual plant liveweight growth and chlorophyll content of leaves were contrasted, the results showed fertilizer（17:8:22）were better than fertilizer（15:5:30）, moreover concentrations from 500 times/dilute to 1000 times/dilute of fertilizer（15:5:30）and from 1000 times/dilute to 2000 times/dilute of fertilizer（17:8:22）were good for testing varieties of airplant.
