不同林型下川续断仿野生种植

Imitation of Wild Dipsacus asperoides Planting in Different Forest Types

以针叶林华山松和阔叶林核桃下仿野生种植的川续断为试材,研究了不同林型下种植的川续断有效成分含量差异性和复合川续断前后林地土壤肥力及其变化情况,以期为川续断林下仿野生种植提供参考依据。结果表明:林下仿野生种植川续断后,2种林型土壤肥力均呈增长趋势,不会对林地造成土壤肥力衰退现象;不同林型种植的川续断有效成分含量存在差异,阔叶树种核桃林下种植的川续断品质优于针叶树种华山松林,且均达到中国药典规定的质量要求;土壤肥力状况对川续断品质存在影响,适宜的土壤肥力状况能提高川续断品质,且川续断对全N、全K的吸收有偏好。因此,该研究认为阔叶树种核桃林下仿野生种植川续断品质要优于针叶树种华山松林,林下复合种植川续断具有可行性,建议林下复合种植时开展平衡施肥措施,以稳定川续断的品质。

The variation of the active constituents of the Dipsacus asperoides planted under different forest types and the soil fertility of the forest land before and after the continuous rotation were studied with the experiment of the wild planting of the wild pine plantation in the coniferous forest and the broad-leaved forest,in order to provide a theoretical basis for the imitation of wild planting under the forest.The results showed that the soil fertility of the two forest types showed an increasing trend after the forest-like wild planting,and there was no soil fertility decline in the forest land.The content of active components in the different forest types was different,and the quality of the Dipsacus asperoides planted under the broad-leaved tree species walnuts was better than that of the coniferous tree Huashan pine forest,and both meet the quality requirements stipulated by the Chinese Pharmacopoeia;the soil fertility status had an impact on the quality of the continuation of the stagnation,and the suitable soil fertility condition could improve the quality of the continuation of the stagnation.The continuation had a preference for the absorption of all N and all K.Therefore,the study concluded that the quality of the wild-type planting of broad-leaved tree species under the walnut plantation was better than that of the coniferous tree species,Huashan pine forest,and it was feasible to plant the composite plant under the forest.It was recommended to carry out balanced fertilization measures during the compound planting under the forest to stabilize the quality of the continuation.
