碳酸氢铵是目前农业生产应用的主要氮素化肥。我站所在的重光大队每年所用碳酸氢铵约占全部氮素化肥的80%以上。由于碳酸氢铵易挥发出氨气,降低肥效,并产生肥害的特点,在水田施用过程中存在着“三大一低”(肥料的用量大、肥效损失大、熏黄秧苗的面积大,施用的效果低)的毛病。群众反映说:“碳酸氢铵是点气,施用不当白费力,少施不见效,多施烧死苗”。针对碳酸氢铵在水田施用中存在的这些问题,我们 Ammonium bicarbonate is the main nitrogen fertilizer used in agricultural production. The heavy brigade where I station where the annual use of ammonium bicarbonate accounts for more than 80% of all nitrogen fertilizers. Because ammonium bicarbonate volatilizes ammonia, reduces fertilizer efficiency and produces fatal traits, there are “three major and one low” (high dosage of fertilizer, large loss of fertilizer effect, large area of ​​smoked yellow seedling, The effect of administration is low). The masses said: “Ammonium bicarbonate is point gas, improper and inefficient use of less effective, more burned dead seedlings.” We address these issues with ammonium bicarbonate in paddy fields
