1.防止潮湿。化肥大多具有吸湿性,吸湿后结成块,发生化学变化,造成肥效损失。为了防潮,化肥应入库房保管,并放干燥阴凉处。堆放时不宜紧靠墙壁,最好离墙30～50cm。 2.防止分解。有的化肥稳定性差,易分解和挥发。如碳酸氢铵比较干燥,在气温20℃以下,就比较稳定;当温度升高或产品含水量高时,就会分解成氨气、二氧化碳和水,在空气中消失。因 1. To prevent moisture. Most fertilizers have hygroscopicity, moisture block after the formation of chemical changes, resulting in fertilizer loss. In order to prevent moisture, fertilizer should be stored in the warehouse, and put dry and cool place. Stacking should not be close to the wall, the best from the wall 30 ~ 50cm. 2. To prevent decomposition. Some poor chemical stability, easy decomposition and volatilization. Such as ammonium bicarbonate is relatively dry, the temperature below 20 ℃, the more stable; when the temperature rises or the product moisture content is high, it will decompose into ammonia, carbon dioxide and water disappear in the air. because
