两种专用肥对空气凤梨生长的影响

为研究空气凤梨快速生长的肥料，选用5个空气凤梨品种和两种专用肥料（15:5:30和17:8:22），设置不同的浓度500倍/稀释、1000倍/稀释、2000倍/稀释、3000倍/稀释、4000倍/稀释及对照，测定空气凤梨的单株增重率和叶片叶绿素含量两个指标。结果表明，肥料15:5:30对5个空气凤梨生长的影响小于17:8:22，肥料15:5:30从稀释浓度500倍到稀释浓度1000倍有利于5个空气凤梨的生长，肥料17:8:22从稀释浓度1000倍到稀释浓度2000倍有利于空气凤梨的生长。

Growth Response of Tillandsia to Two Special Fertilizers

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.
