通过对实验室培养试验和田间试验结果综合分析 ,表明与硝化抑制剂 ,2 ,5 二氯硝基苯有相似结构的 2 氯 5 氟 硝基苯也具有硝化抑制作用 ,但在不同的土壤上 ,其效果存在明显差异 ,在土壤肥力高的潮土上的效果显著 ,抑制剂的施用与否可使用土壤中NO3 N的含量相差 2— 3倍。玉米以碳铵作N源 ,减少正常N肥用量 2 0 % ,施用 2 氯 5 氟 硝基苯 ,玉米产量较对照增产 12 6% ,达到极显著水平
Through the comprehensive analysis of the results of laboratory culture experiments and field experiments, we found that 2-chloronitrobenzene-nitrobenzene with similar structure as nitrification inhibitor and 2, 5-dichloronitrobenzene also has the effect of inhibiting nitrification, but on different soils , The effect of which is obviously different. The effect on the soil with high soil fertility is remarkable, and the content of NO3 N in the soil that can be used with or without the inhibitor can vary by 2-3 times. Corn with ammonium bicarbonate as a source of N, reducing the amount of normal N fertilizer 20%, the application of 2 chlorine 5 nitrofluorobenzene, corn yield increased 12.6% compared with the control, reaching a significant level
