过量施氮条件下硝化抑制剂对辣椒硝酸盐含量的影响

Effect of Nitrification Inhibitor on Nitrate Content of Pepper Under Excessive Applied Nitrogen Fertilizer Conditions

以辣椒品种"C-19"为试材,采用随机区组设计,测定了5种不同氮肥对辣椒硝酸盐含量和土壤中硝态氮含量的影响。结果表明:使用土地精硝化抑制剂可使辣椒硝酸盐和土壤中硝态氮含量都有所降低,土地精作为一种新型硝化抑制剂可以提高N肥利用率,减少N肥对环境的污染。

Taking pepper varieties of ‘C-19 ’ as material, the effect of 5 different nitrogen fertilizers on pepper nitrate content and nitrate nitrogen content in soil were studied using a randomized block design. The results showed that ‘Iudijing＇ nitrification inhibitors could reduce pepper nitrate and nitrate nitrogen content in soil, as a kind of new nitrifying inhibitor, ‘Tudijing ’ nitrification inhibitors could increase fertilizer utilization ratio and reduce nitrogen fertilizer on environment pollution.
