两种经济林下黄芪仿野生种植

以核桃林和油橄榄林两种经济林下复合种植的黄芪为试材，研究不同品种经济林下种植的黄芪有效成分含量差异性和复合种植黄芪前后土壤肥力及其变化情况。结果表明，两种经济林下种植黄芪后土壤肥力呈增长趋势，不会对经济林产量造成影响；两种经济林下种植的黄芪有效成分含量存在差异，落叶经济林核桃林下种植的黄芪品质优于常绿经济林油橄榄林，且均达到中国药典规定的质量要求；黄芪种植对土壤要求不高，适宜的土壤肥力能保证黄芪较高的品质，黄芪种植对有机质、钾需求较高，对磷需求较低。经济林下复合种植黄芪模式具有可行性，且落叶经济林核桃林下种植的黄芪品质优于常绿经济林油橄榄林。以期为经济林下黄芪种植提供理论依据。

Simulated Wild Planting of Astragalus membranaceus under Two Economic Forests

Using Astragalus membranaceus planted under two economic forests of walnut forest and olive forest as test materials, this study investigated the differences in effective components contents of Astragalus membranaceus planted under different varieties of economic forests, as well as the changes in soil fertility before and after the compound planting. The results showed that the soil fertility increased after planting of Astragalus membranaceus under the two economic forests, which would not affect the soil fertility and the economic forest; the effective components contents of Astragalus membranaceus were different, the quality planted under deciduous economic forests(walnut forests) was better than that of evergreen economic forests (olive forests), and both met the quality requirements specified in Chinese Pharmacopoeia. The planting requirements for soil were not high, and suitable soil fertility could ensure higher quality of Astragalus membranaceus, while the planting had higher requirements for organic matter and potassium,but lower requirements for phosphorus.The model of compound planting of Astragalus mem branaceus under economic forests was feasible, and the quality planted under deciduous economic forests was better than that of evergreen economic forests, to provide theoretical basis for the cultivation of Astragalus membranaceus under economic forests.
