When fertilizing amount exceeded 0.59g N/pot, nitrate content of urea treatment exceeded national band third criterion. Combined with vegetable yield, it could be concluded that fertilizing tolerated dose of slow-release nitrogen fertilizers and urea was the optimal fertilizing amount.4.
在第一茬菠菜处理中,施用缓释氮肥的蔬菜硝酸盐含量都没有超过1440mg/kg(国家三级标准),施用尿素处理的硝酸盐含量在施肥量超过0.59g/盆时,超过国家三级标准,结合产量得出,缓释氮肥和尿素处理的安全施肥量即为最佳施肥量。
