| 为了解不同种植模式和间作大蒜密度对当归质量的影响，寻找能有效缓解当归连作障碍、提高当归内在质量的最佳的间作大蒜种植模式，设置轮作和连作两种种植模式，轮作和连作分别设置当归与大蒜间作密度2∶1（M2）、3∶1（M3）、4∶1(M4) 三个处理及单作对照，并对采收阴干当归根内在质量指标总灰分、酸性不溶性灰分、醇溶性浸出物、挥发油、阿魏酸含量测定分析。结果表明：不同间作大蒜密度下各指标呈先增后减趋势，各含量在M2处理达到最大值；不同种植模式下挥发油和阿魏酸含量轮作大于连作，总灰分和酸性不溶性灰分含量连作大于轮作，醇溶性浸出物不明显；不同种植模式和间作大蒜密度下，挥发油、阿魏酸都在轮作种植模式M2处理含量最高，为0.56%、0.084%，分别比单作提高了0.09%、0.032%；总灰分含量在轮作种植模式M4处理含量最低，为4.08%；酸性不溶性灰分在连作种植模式单作处理含量最低，为0.5%；醇溶性浸出物含量在连作种植模式M2处理含量最高，为65%；但均符合药典含量规定。综合考虑，轮作种植模式M2处理下，当归质量指标最好，是最佳的间作大蒜种植模式，可以有效促进当归生长，提高当归质量，有效减缓当归连作障碍问题。 |

| The study is to identify the effects of different planting patterns and the density of intercropping angelica and garlic on the quality of angelica, and to look for the optimal garlic intercropping pattern in which the problem caused by continuous cropping of angelica can be effectively alleviated and the intrinsic quality of angelica can be improved. Rotation and continuous cropping patterns were provided with three treatment of intercropping density 2∶1(M2), 3∶1(M3), 4∶1(M4) respectively. The monoculture was the control. Analysis was made on the quality index of total ash, acid insoluble ash, alcohol soluble extract, volatile oil and the content of ferulic acid in the root of angelica dried in the shade. The results showed that each index showed a trend of increase first and decrease then in different density of intercropping, and all the content in M2 reached the maximum value. The volatile oil and ferulic acid content in the rotation was greater than those in the continuous cropping, while total ash and acid insoluble ash content in continuous cropping were greater than those in rotation, and there was no difference in alcohol soluble extract. The content of the volatile oil and ferulic acid reached maximum of 0.56% and 0.084% in M2 in the rotation pattern, 0.09% and 0.032% more than those in monoculture respectively. The content of total ash content reached minimum of 4.08% in M4 in the rotation. The content of acid insoluble ash reached minimum of 0.5% in monoculture in the continuous cropping patterns. The content of ethanol soluble extract reached maximum of 65% in M2 in the continuous cropping pattern, which met the requirements of pharmacopoeia. In conclusion, the rotation pattern with M2 was the optimal one, which produced angelica of the best quality index, effectively promoted the growth of angelica, and alleviated the problem of angelica resulted from continuous cropping. |
