摘要:
以三年生人参为试材，采用盆栽试验改变霍格兰营养液氮素形态和浓度的方法，研究了施入不同浓度的铵态氮和硝态氮对人参根生理指标的影响，以期为人参在栽培生长过程中氮肥的使用提供参考依据。结果表明：施入外源氮随氮素浓度的升高人参根中可溶性糖含量逐渐降低，铵态氮处理较硝态氮处理降低效果更显著。人参根中淀粉、游离氨基酸含量随氮素浓度的升高逐渐升高，在25 mmol·L-1铵态氮处理时人参根中淀粉、游离氨基酸含量最高，显著高于25 mmol·L-1硝态氮处理，铵态氮处理增加较硝态氮更为明显。添加硝态氮对人参根中可溶性蛋白质含量随施氮浓度的升高逐渐升高，添加铵态氮对人参根中可溶性蛋白质含量随施氮浓度的升高呈先升高后降低的趋势，在15 mmol·L-1含量最高，添加25 mmol·L-1铵态氮人参根中可溶性蛋白质显著低于对照。人参根中总蛋白质含量随氮素浓度的升高呈先升高后降低的趋势，在15 mmol·L-1铵态氮处理时含量最高，5、15 mmol·L-1铵态氮处理人参根中总蛋白质含量显著高于同浓度的硝态氮处理。
Abstract:
Taking three-year-old Panax ginseng plants as the test materials,a pot experiment was conducted to study the effects of different concentrations of ammonium nitrogen and nitrate nitrogen on the physiological indicators of Panax ginseng roots by altering the nitrogen form and concentration in Hoagland nutrient solution,in order to provide reference for the use of nitrogen fertilizers during the cultivation and growth of Panax ginseng.The results showed that the soluble sugar content in Panax ginseng root decreased gradually with the increase of nitrogen concentration，and the reduction effect of ammonium nitrogen treatment was more significant than that of nitrate nitrogen treatment.The contents of starch and free amino acid in Panax ginseng root increased gradually with the increase of nitrogen concentration，and the contents of starch and free amino acid were the highest in 25 mmol·L-1 ammonium nitrogen treatment，which was significantly higher than that in 25 mmol·L-1 nitrate nitrogen treatment，and the increase of ammonium nitrogen treatment was more obvious than that in nitrate nitrogen treatment.The content of soluble protein in Panax ginseng root increased gradually with the increase of nitrogen application concentration，and the content of soluble protein in Panax ginseng root increased first and then decreased with the increase of nitrogen application concentration，and the content of soluble protein in Panax ginseng root with the addition of ammonium nitrogen increased the highest at 15 mmol·L-1，and the soluble protein in Panax ginseng root with the addition of 25 mmol·L-1 ammonium nitrogen was significantly lower than that in the control.The total protein content in Panax ginseng root increased first and then decreased with the increase of nitrogen concentration，and the highest content was found at 15 mmol·L-1 ammonium nitrogen treatment.The total protein content in Panax ginseng root at 5,15 mmol·L-1 ammonium nitrogen treatments were significantly higher than that at the same concentration of nitrate nitrogen treatment.
