| 摘 要： | 在施等量有机肥的前提下,随着施氮量的增加,辣椒营养生长旺盛,株高株幅增加;辣椒产量在一定范围的施氮量内逐步增加,超过一定施氮量反而下降;随着施氮量的增加,辣椒果实和叶片的硝酸盐含量均随之上升,其中以叶片中积累量最高,其次是果皮,果肉中硝酸盐的含量最低;各处理对辣椒亚硝酸盐的积累没有影响。

| Abstract: | Field experiments were carried out to study the effect of nitrogen amount on yield and nitrate accumulation in peppers. The results showed that the pepper yield increased as the application amounts of nitrogen fertilizer increased in determinate range. But too much nitrogen fertilizer begot flowers and young fruits dropping and reduced the yields. In contrast, nitrate content in leaves and fruits of pepper increased continuously with the increase of nitrogen application. The increased rate was highest in leaves, middle in pericarp and lowest in pulp. The results also showed that supplying nitrogen fertilizer did not affect the nitrite content in peppers. |
