为了抑制NH_4-N的硝化作用,有些学者建議在土壤根系施用酚类化合物,例如4-(?)-2-硝基酚、2-硝基酚、2-甲基-4-氯酚、2-甲基-4溴酚、2-甲基-4氯-6-硝基酚等均适用直接施入土壤中时,剂量为土重之2-150 ppm,也可以和肥料混合施用,用量为肥料用量之0.5%。酰替苯胺的衍生物或硝基替苯胺类化合物,也可用作硝化作用的抑制剂。用这些化合物直接施入根系周围时,浓度不要超过土重的50 ppm;与氮肥共同施用时,浓度不应超过銨肥重的0.5%;若与氮肥混合
In order to inhibit the nitrification of NH 4 -N, some scholars suggest that the application of phenolic compounds in soil roots such as 4 - (?) - 2-nitrophenol, 2-nitrophenol, 2-methyl- - methyl-4-bromophenol, 2-methyl-4-chloro-6-nitrophenol, etc. Apply directly to the soil, the dose of heavy soil 2-150 ppm, can also be mixed with the fertilizer application, the amount of Fertilizer dosage of 0.5%. Anilide derivatives or nitroanilides can also be used as inhibitors of nitrification. When these compounds are applied directly to the surroundings of the root, the concentration should not exceed 50 ppm of soil weight; when applied together with nitrogen fertilizer, the concentration should not exceed 0.5% of the weight of ammonium fertilizer; if mixed with nitrogen
