碳酸氢铵简称碳铵,是目前最常见和广泛施用的一种氮素化肥。因其价格相对较低,施后见效快而深受农民朋友的欢迎。但是碳铵性质不稳定,易于挥发,因而在施用中应避免以下几种不正确的做法。 1.地表撒施或浅施 有些农民只求方便,常常将碳酸氢铵撒于地表,也有的虽开沟施用,但开沟甚浅,往往不足5cm深,掩埋不严不细,这种做法极不科学。一是浪费肥料,致使80％以上的氮素白白挥发损失掉,利用率极低;二是极易灼伤作物。
Ammonium bicarbonate referred to as ammonium bicarbonate, is the most common and widely used a nitrogen fertilizer. Because of its relatively low price, Shi quick and effective farmers by friends welcome. However, the ammonium bicarbonate is unstable in nature and volatile, so the following incorrect practices should be avoided during application. 1. Surface spreading or shallow application Some peasants only seek convenience, often ammonium bicarbonate sprinkled on the surface, while others ditching application, but the ditching is very shallow, often less than 5cm deep, burial is not strict is not fine, this approach Very unscientific. First, a waste of fertilizers, resulting in more than 80% of the nitrogen loss of volatile white, very low utilization rate; the second is extremely easy to burn crops.
