(一)化肥的合理贮存。据科研单位测定,碳酸氢铵露天放置,在16℃情况下氮肥损失率:1天是3.4％,5天是10.6％,10天是18％,15天达26％;在20℃情况下氮肥损失率:1天是8.8％,5天是48％,10天是74％,15天是77％;在32℃情况下氮肥损失率:1天是18.9％,5天是67.9％,10天是93.6％,15天达97.6％。所以,化肥在贮存保管时不能露天堆放,特别是夏、秋高温季节,要注意遮荫降温。包装要严密,散装要压实,加盖封闭,最好在上面铺上一层泥土。 (二)酸性化肥不能与碱性物质混存。硫酸铵、氯化铵、硝酸铵、过磷酸钙等都是酸性肥料,不能与碱性物质如石灰氮、碳酸氢铵、碳酸钾、火碱、波尔多液、纯碱、硫磺、石硫合剂、石灰、草木灰等混存。如铵 (A) the rational storage of fertilizers. According to scientific research units measured, ammonium bicarbonate placed in the open air, nitrogen loss rate at 16 ℃: 1 day is 3.4%, 5 days is 10.6%, 10 days is 18%, 15 days up to 26%; at 20 ℃ nitrogen fertilizer Loss rates: 8.8% for 1 day, 48% for 5 days, 74% for 10 days and 77% for 15 days; loss of nitrogen fertilizer at 32 ° C: 18.9% for 1 day, 67.9% for 5 days, 10 days Is 93.6%, 97.6% on the 15th. Therefore, the fertilizer can not be stored in the open storage, especially in summer and autumn hot season, we should pay attention to shade and cool. Packaging should be tight, bulk to be compacted, stamped closed, it is best to spread a layer of soil above. (B) acidic fertilizers can not be mixed with alkaline substances. Ammonium sulfate, ammonium chloride, ammonium nitrate, superphosphate are all acidic fertilizers, not with alkaline substances such as lime nitrogen, ammonium bicarbonate, potassium carbonate, caustic soda, Bordeaux mixture, soda ash, sulfur, lime sulfur mixture, lime , Ash and other mixed. Such as ammonium
