化肥的性质大都不够稳定,各生产队、作业组和农户要妥善保管化肥,以防肥分损失,降低使用效果。1.建立通风、阴凉、干燥的库房化肥一般都溶于水,沾水或受潮后容易溶化流失,或者结成硬块,不便于使用。碳酸氢铵极易潮解,造成氮素挥发。当温度超过30℃,环境又潮湿时,10天间碳酸铵的分解率高达93％,是干燥时分解率的27倍。尿素在 Most of the nature of chemical fertilizer is not stable enough, the production team, operating groups and farmers should take proper care of chemical fertilizers to prevent loss of fertilizer points, reducing the use of results. 1. To establish a ventilated, cool, dry warehouse Chemical fertilizers are generally soluble in water, water or damp easily melted loss, or the formation of lumps, not easy to use. Ammonium bicarbonate easily deliquescence, resulting in nitrogen volatilization. When the temperature exceeds 30 ℃, the environment is damp, the 10-day decomposition of ammonium carbonate as high as 93%, 27 times the decomposition rate when dry. Urea in
