| 摘 要： | 随着氮肥投入量增加,各个层次土壤中硝酸盐也明显增加,在LF和HF处理中,各个层次土壤中硝酸盐与施肥量成正相关。HF处理土壤中硝酸盐是CK处理的数倍到数十倍。在各个处理中,硝酸盐主要在30~90 cm和150 cm土层中形成累积。随着施肥量的增加,作物硝酸盐含量也随着增加。

| Abstract: | The research shows that the concentration of nitrate in different deeps soil is increased with amount of N input.It is positive relation with amount of N input,The concentration of nitrate in treat HF is more than ten times in treat CK.Nitrate is mostly accumulated in soil deeps 30-90cm and 150cm.Concentration of nitrate in plant is increased in evidence with N input. |
