化肥是农业生产的重要紧俏物资,为了不误农时,农民朋友纷纷提早抢购备储化肥。为了减少化肥贮藏损失,这里给农民朋友介绍一下化肥贮藏过程中应注意的几点:一、忌高温。研究表明:磷铵露天放置,在气温16℃的情况下,氮的损失率是:1天为3.4%,5天为10.6%、10天为18%,15天为26%;在气温20℃的情况下,氮的损失率为:1天为8.8%,5天为48%,15天为77%;在气温32℃的情况下,氮的损失率为:1天为18.9%,5天为67.9%,10天为93.6%。由以上的数据可以看出,环境温度越高,氮的损失越大。碳酸氢铵、氨水等氮肥的稳定性差,当
Fertilizer is an important staple of agricultural production, in order not to be wrong, farmer friends have snapped up stockpile of fertilizer. In order to reduce the loss of fertilizer storage, here to farmers friends to introduce fertilizer storage process should pay attention to several points: First, avoid high temperatures. The results showed that when the ammonium phosphate was placed in the open air, the nitrogen loss rate at the temperature of 16 ℃ was 3.4% in 1 day, 10.6% in 5 days, 18% in 10 days and 26% in 15 days. At the temperature of 20 ℃ , The loss rate of nitrogen was 8.8% for 1 day, 48% for 5 days and 77% for 15 days. At the temperature of 32 ° C, the loss rate of nitrogen was 18.9% for 1 day and 5 days for 5 days 67.9% for 10 days and 93.6% for 10 days. As can be seen from the above data, the higher the ambient temperature, the greater the loss of nitrogen. Ammonium bicarbonate, ammonia and other nitrogen stability is poor, when
