摘要
采用正交试验研究不同配比的磷钾肥对北沙参中欧前胡素、异欧前胡素和补骨脂素的含量及产量的影响。结果显示:一定范围内配合施用磷钾肥北沙参根干重、小区产量增加,且磷肥对产量影响大于钾肥,当肥料施用量为P2O5360 kg·hm-2,K2O 270 kg·hm-2和P2O5360 kg·hm-2,K2O 180 kg·hm-2时北沙参根干重达到最优值,小区产量最大。磷钾肥对北沙参中欧前胡素、异欧前胡素含量的影响表现为随磷、钾肥的增施而升高,且磷肥影响较大,当施用P2O5360 kg·hm-2,K2O270 kg·hm-2时异欧前胡素含量最高,欧前胡素量和补骨脂素含量均较高;施用P2O5360 kg·hm-2,K2O 180 kg·hm-2时欧前胡素量最大,异欧前胡素量也较大。因此,当磷钾肥的施用量分别为P2O5360 kg·hm-2,K2O 180 kg·hm-2时,成本低,优质高产,适于推广至农业生产实践中。
By a orthogonal experiment,the influence of different ratio of phosphorus and potassium fertilizers on imperatorin,isoimperatorin and psoralen contents and yield of Glehnia littoralis were studied. The results showed that root dry weight and the yield of G. littoralis increased when reasonably applied phosphorus fertilizer combined with potassium fertilizer within a certain range. And the influence of phosphorus fertilizer was greater than that of potassium fertilizer. The optimal value of root dry weight and yield achieved at both P2O5360 kg · hm^- 2,K2 O 270 kg· hm^- 2and P2O5360 kg · hm^- 2,K2 O 180 kg· hm^- 2. The effects of different phosphorus and potassium treatments on the content of imperatorin,isoimperatorin and psoralen in G. littoralis were determined,which shows that the content increased with the moderate increase of phosphorus and potassium. And the effects of phosphorus fertilizer were more significantly. The isoimperatorin content achieved the largest value at P2O5360 kg · hm^- 2,K2 O 270 kg· hm^- 2,also a larger content of imperatorin and psoralen. The imperatorin content is the largest when applied P2O5360 kg · hm^- 2,K2 O 180 kg· hm^- 2,and the isoimperatorin content was higher as well. So that the treatment of P2O5360 kg · hm^- 2,K2 O 180 kg · hm^- 2are suitable for promote to the agricultural production,which could improve the quality and yield of G. littoralis.
