近年来,通过技术培训,农民科学种田的水平越来越高,许多种植大户、专业合作社也趋向于自己混配肥料。但在混合过程中也遇到了一些难题:几种肥料能溶解了混配在一起冲施吗?如何混配才不会影响肥效、不会发生化学反应呢?因此,只有了解常见氮、磷、钾单质化肥的物理性状,尤其是吸湿性、结决陛和粒度等常识,才能合理正确施用混配肥料。肥料混后吸湿性和结块性越小越好吸湿性是指化肥吸收空气中水分的能力;结块性与单质肥料颗粒表面的吸湿性有关,吸湿性大的肥料易结块。
In recent years, through technical training, farmers have become more and more scientific and farming. Many large-scale farming households and professional cooperatives tend to mix their own fertilizers. But in the process of mixing also encountered some problems: how many kinds of fertilizers can dissolve mixed with Chong Shi? How to mix will not affect fertilizer efficiency, does not occur chemical reaction? Therefore, only to understand the common nitrogen, phosphorus, Potassium fertilizer elemental physical properties, especially hygroscopicity, determination and particle size and other common sense, in order to properly and properly mixed with fertilizer. Fertilizer mixed moisture and agglomeration of the smaller the better The hygroscopicity refers to the ability of chemical fertilizer to absorb moisture in the air; agglomeration and single-factor fertilizer particles on the surface of the hygroscopicity, large moisture-prone fertilizer caking.
