摘　　要：为了比较含硝化抑制剂的硝氯基肥料与普通硝氯基肥料在保护地叶菜上的使用情况,以小白菜为试验对象,开展了盆栽试验。试验结果表明:与普通硝氯基肥料相比,由于含硝化抑制剂的硝氯基肥料的养分释放速率缓慢,导致其处理的小白菜生物量减少11.02%~13.84%,而收获后的土壤中碱解氮、有效磷和速效钾含量分别平均提高15.7%-54.0%.23.0%-81.9%和2.8%~18.4%;在追求快产快销的保护地叶菜栽培中,应谨慎使用含硝化抑制剂的硝氯基肥料。In order to compare the application of chlorine nitro based fertilizer containing nitrification inhibitor and common chlorine nitro based fertilizer in protected field leaf vegetables,pot experiments were carried out on Chinese cabbage.The results showed that compared with common chlorine nitro based fertilizer,due to the slow nutrient release rate of chlorine nitro based fertilizer containing nitrification inhibitor,the biomass of Chinese cabbage was reduced by 11.02%〜13.84%,and after harvest,the available nitrogen,available phosphorus and available potassium in the soil was increased by 15.7%~54.0%,23.0%~81.9% and 2.8%~18.4%,respectively.Chlorine nitro based fertilizer containing nitrification inhibitor should be carefully used in the cultivation of protected field leafy vegetables with fast production and fast marketing.
