氮肥与磷肥质量检验的方法

作物的生长都必须依靠土地中必要的肥料和营养完成发育周期,合理地使用氮肥和磷肥,可以促进作物的生长发育,增加产量,能够改善土壤和农作物品质。近年来大多数土地中的含氮、磷素不均衡,损耗流失比较严重,不易在土壤中积累,而现代集约型农业又对土壤中的氮肥和磷肥有着过多的损耗。因此,为了生产出能够促进作物生长的好肥料,对氮肥与磷肥质量的检验是非常有必要的。本文针对氮肥和磷肥质量物理检验的方法进行了分析探讨。

Quality Inspection Method of Nitrogen and Phosphate Fertilizer

The growth of the crops depend on the necessary fertilizer and nutrition to complete its development cycle, and reasonable use of nitrogen and phosphate fertilizer can promote growth and development of crops, increase production, and improve the quality of soil and crops. In recent years, the content of nitrogen and phosphorus is not balanced, the loss is serious, and it is not easy to accumulate nitrogen and phosphate in the soil, while the modern intensive agriculture brings lots of losses of nitrogen and phosphate in the soil.Therefore, in order to produce the high quality fertilizer that can promote growth of crops, the quality inspection of nitrogen and phosphate is necessary. The physical inspection method of nitrogen and phosphate quality is analyzed in this paper.
