摘要
通过盆栽试验,研究了石灰性褐土条件下,喷施钼肥、锌肥、锰肥对不同类型蔬菜硝酸盐含量和产量的影响。结果表明,供试的根菜类、叶菜类、茎菜类蔬菜,喷施钼肥、锰肥和锌肥都能显著降低硝酸盐含量,而且对其产量也产生了一定的影响。通过喷施微量元素可以降低因施氮产生的硝酸盐含量增加的不良后果。
This paper studies the effects of micronutrient on nitrate content and yield of various vegetables under the condition of calcareous cinnamon soil with pot experiment. The results show that spraying every kind of micronutrient fertilizers could decrease nitrate content significantly and influence the yield to some extent Through spraying microelements, nitrate content can be decreased, and adverse consequences can be weaken by spraying nitrogen fertilizer.
