摘要
科学施肥不仅可以合理地确定施肥量和肥料中营养元素比例,提高肥料利用率,还可以保护生态,协调养分,防治病虫和分配有限资源。为探寻芦荟在成都平原地区的高产优质栽培技术,依据平衡施肥原理,研究了不同施肥条件下2种芦荟株高和冠幅生长的情况,结果表明:芦荟的最佳施肥配比为PK+N(1∶3)。
Scientific fertilization could not only rationally determine fertilization rate and nutrient ratio ,but also increase fertilizer efficiency ,with protecting ecology,coordinating nutrient,controlling pest and allocating limited resources.In order to explore the high yield and quality cultivation techniques of aloe in Chengdu plain, according to the principle of balanced fertilization, this test studied the conditions of plant height and crown width of two aloes under different fertilizer level The results showed that the optimum ratio of fertilization was PK＋N （ 1：3 ）.
