通过盆栽试验研究小麦氮锌配施效应.结果表明:在土壤供锌较低(0.2 mg/kg)的条件下,氮肥用量由50 mg/kg提高到150 mg/kg时,小麦籽粒锌质量分数增加了140%;在土壤供锌较高(5 mg/kg)的条件下,土壤氮肥用量由50 mg/kg提高到150 mg/kg时,小麦籽粒锌质量分数增加了61%.增施氮肥,可以促进小麦地上部锌向籽粒中转移,从而有利于锌在籽粒中的积累.充足的氮肥施用对小麦籽粒锌累积具有非常重要的作用.
The pot experiment was conducted to study the combined effect of nitrogen and zinc in wheat. The results showed that when the amount of nitrogen fertilizer increased from 50 mg / kg to 150 mg / kg under the condition of low zinc supply (0.2 mg / kg) Increased by 140%. When the soil Zn supply was increased from 50 mg / kg to 150 mg / kg under the conditions of high zinc supply (5 mg / kg), the Zn content in wheat grains increased by 61% , Which could promote the transfer of above-ground zinc of wheat to grain, which is beneficial to the accumulation of zinc in grain.Ample application of nitrogen fertilizer is very important to the accumulation of zinc in wheat grain.
