植物能通过气孔吸收营养。把含有作物需要的养分,以液体的形态喷在作物的叶片上称为叶面施肥,这种液体就是常称的液肥。施用液肥,见效快,肥料利用率高,并能补充作物以某些必需的微量元素,作为一种土壤施肥的辅助方法,深受农户欢迎。但是,目前市售的液肥良莠混杂。下面介绍一些简易的液肥鉴别方法。看比重液体肥料凡浓度大的,所含的养分就多,比重就大。测比重的简易方法是先称液肥瓶装时的毛重(克),倒出液肥,再称瓶重,毛重减去 Plants can absorb nutrients through the stomata. Spraying the nutrients needed for a crop, spraying it on the leaves of a crop in the form of a liquid, is called foliar fertilization. This liquid is often referred to as liquid fertilizer. Application of liquid fertilizer, quick, high utilization of fertilizers, and can supplement crops with some necessary trace elements, as a secondary method of soil fertilization, welcomed by farmers. However, currently available liquid fertilizers are mixed. Here are some simple liquid fertilizer identification methods. See the proportion of liquid fertilizer Where the concentration of large, contains more nutrients, the proportion of large. The simple method of measuring gravity is to first call the gross weight (g) of bottled liquid fertilizer, poured liquid fertilizer, then weigh the bottle, the gross weight minus
