摘    要:在田间小区试验条件下,研究不同氮肥用量,不同磷肥用量对菠菜中硝酸盐累积量的影响。结果表明:菠菜中硝酸盐累积量随氮肥用量的增加而增大,氮磷配施能使菠菜中硝酸盐的累积量降低,其最佳氮磷配比施用量为138kg/hm^2和46.2kg/hm^2。

关 键 词:氮肥  磷肥  菠菜  硝酸盐累积量

Abstract:The infulence of different nitrogen and phosphorus fertilizer appliction quantity on nitrate cumulant in spinach was studied on condition of field experiment.The results show that the nitrate cumulant of spinach increased according to the increasing of nitrogen fertilized application.The method of the application of nitrogen mingled phosphorus fertilizer can reduced nitrate cumulant in spinach.The best fertilizer application proportion of nitrogen fertilizer and phosphorus fertilizer is 138 kg/hm~2 and 46.2 kg/hm~2.
Keywords:nitrogen fertilizer  phosphorus fertilizer  spinach  nitrate cumulant
