一、腐殖酸铵的肥效(一)腐殖酸铵(以下简称腐铵)在不同作物上的增产效果:我省各地腐铵在水稻、玉米、小麦、土豆、油菜、烤菸等作物上做了大量的试验,在217个试验中,除水稻11例、小麦1例减产外,一般都有较好的增产效果,其增产的平均值见表1。在蔬菜上的试验也证明,腐铵有一定 First, the fertilizer efficiency of ammonium humate (A) ammonium humate (hereinafter referred to as ammonium) in different crops on the yield effect: all parts of our province in the rice, corn, wheat, potato, rape, flue-cured tobacco and other crops to do In a large number of experiments, in 217 experiments, in addition to 11 rice and 1 wheat reduced yield, generally have a better yield-increasing effect, the average yield increase in Table 1. Experiments on vegetables also prove that there is a certain ammonium
