长效碳铵是普通碳铰在生产过程中加入适量铵离子稳定剂，形成共结晶的一种新型肥料。为探索该肥在早稻的施用效果，并与等肥量普通碳铰和尿素比较肥效和经济效益，特设计本试验，旨在为推广该肥提供科学依据，现将试验结果分述于下。一、材料与方法试验田为乌泥田，土壤基础养?
Long-acting ammonium bicarbonate is a common carbon hinge in the production process by adding appropriate amount of ammonium ion stabilizer, a co-crystallization of a new type of fertilizer. In order to explore the application effect of this fertilizer in early rice and to compare fertilizer efficiency with economic benefits with common carbon hinge and urea with the same fat content, this experiment was specially designed to provide a scientific basis for popularizing this fertilizer. Now the experimental results are described below. First, the material and method Experimental field for the Ukrainian muddy soil, the basic soil culture?
