摘要
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。
In order to enable air plant to grow fast, 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/di- lute, 4000 times/dilute and control group. Percentage of individual plant live weight growth and chlorophyll con- tent of leaves were contrasted, the results showed fertilizer（17：8：22）were better than fertilizer（15：5：30）, more- over 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 air plant.
