1.注意防潮大部分固体化学肥料都有不同程度的吸湿性(或称回潮)。因此,在潮湿或高温的环境下,有很多肥料会吸湿潮解或结块,有的则引起肥料中氨的挥发或养分流失。潮解是由于贮存环境中空气的水蒸气分区大于肥料表面饱和溶液的水蒸气分压,饱和溶液就从空气中吸水稀释成溶液,稀溶液将肥料溶解,直 1. Attention to moisture Most solid chemical fertilizers have varying degrees of hygroscopicity (or re-moisture). Therefore, in moist or hot environments, many fertilizers hygroscopic deliquesce or clump, while others cause ammonia volatilization or nutrient depletion in the fertilizer. The deliquescence is due to the water vapor partitioning of the air in the storage environment is greater than the partial pressure of water vapor in the saturated solution on the surface of the fertilizer. The saturated solution is diluted with water to dilute the solution into the air. The dilute solution dissolves the fertilizer
