摘要
通过调查山东省马铃薯主产区肥料施用状况,分析不同地区的氮肥偏生产力,为马铃薯高产、高效、优质生产以及合理施肥提供参考。分析结果表明,不同地区马铃薯氮肥偏生产力差异较大,从高到低分别是胶州164.25 kg/kg、安丘146.93 kg/kg、平度129.87 kg/kg、肥城119.50 kg/kg、滕州100.13 kg/kg。根据国家双减目标,针对山东省实际情况,提出多施有机肥、增加追肥次数、减少氮肥施用量等措施,提高氮肥偏生产力。
By investigating the fertilization status in main potato producing areas in Shandong Province,the partial productivity of nitrogen in different areas was analyzed to provide references for high-yielding,high-quality and high-benefit production and reasonable fertilization.The results showed that the partial productivity of nitrogen was different in different areas,which were 164.25,146.93,129.87,119.50 and 100.13 kg/kg for potato in Jiaozhou,Anqiu,Pingdu,Feicheng and Tengzhou,respectively.According to the national double reduction target and the actual situation of Shandong Province,the measures such as more application of organic fertilizer,more times of topdressing fertilizer and less rate of nitrogen fertilizer were put forward to improve the partial productivity of nitrogen fertilizer.
