　　在水溶肥进行喷施时，我们应总体上把握“就低不就高”的原则，尤其是在温度较高时，避免因蒸发而造成水溶肥液浓度过高灼伤叶片，叶面喷施的浓度也因肥料品种和作物种类而异。对于不同类型的水溶肥，喷施浓度也应区别对待，通常大量元素的浓度在0.2%-2%之间为宜，微量元素则为 0.01%-0.2%。

　　于功能型水溶性肥料，如市场上常见的含氨基酸水溶肥、含腐植酸水溶肥、含海藻酸水溶肥等产品，一般在施用时会稀释500-1000倍再进行叶面喷施。此外，在施用含生长调节物质的水溶肥时，也应特别注意浓度的控制。如浓度为 0.5-1.0毫升/升的三十烷醇能促进种子萌发，但浓度超过1.0毫升/升时就会对种子发芽产生抑制作用。
