摘要

采用3种不同包膜控释肥进行马蹄莲盆栽试验

并与普通复合肥进行肥效对比

研究不同肥料在花卉盆栽上的养分淋失情况

探讨控释复合肥对马蹄莲生长发育的影响。结果表明

控释复合肥处理的马蹄莲其株高、生长势、叶绿素都明显优于普通复合肥和对照;在马蹄莲生长过程中

控释复合肥处理的淋滤液pH值始终处于平稳变化的状态;控释复合肥的缓慢释放能更有效地降低氮、磷、钾的淋失率

保持了马蹄莲营养生长的平衡

为马蹄莲的生殖生长提供充足的养分。

Abstract

Pot experiment was conducted to study the effects of three controlled release fertilizers(CRFs)on growth of calla in comparison with common compound fertilizer and to investigate leaching loss rate of nutrients in CRF by measuring nutrients content in leachate.The results indicated that the plant height

growth potential and chlorophyll content in CRF treatments were better than those in common compound fertilizer treatments and control.Changes of pH of leachate were always smooth during the whole growth season of calla because controlled release compound fertilizer could release nutrients slowly

which could reduce the leaching loss rate of N

K effectively

provide sufficient nutrients for the flowering of calla

and thus keep balance of the growth of calla.
