Investigation of Ecological Environment of Mountain Cultivated Panax ginseng and Their Associated Plants / 中国实验方剂学杂志

ABSTRACT

Objective:To investigate the ecological environment and associated plants of mountain cultivated Panax ginseng were investigated in Xifeng county，Kuandian Manchu autonomous county and Huanren Manchu autonomous county of Liaoning province，in order to provided suggestions on the development of the mountain cultivated P. ginseng in these areas and necessary reference materials for the analysis of ecological suitability of mountain cultivated P. ginseng. Method:The field survey was conducted through sample plot survey in the survey pattern ofbased on representative area-sample plot-quadrat，literature review and data collation， were conducted to record indicators， calculate relevant parameters and make summary. Result:The associated plants were investigated based on 42 samples of mountain cultivated ginseng collected. A total of 95 plant species were identified. The correlation analysis was made on the six main species with an occurrence frequency of higher than 33%， and they were all positively correlated. Asarum heterotropoides var. mandshuricum was the strongest，which was followed by Schisandra chinensis， and Tilia tuan was the strongest in the arbor layer. The survey also found many problems in these areas，such as fewer large-scale planting bases， more scattered households，mixed germplasms，irregular planting techniques，simple planting mode and less sources of economic income generation. Conclusion:Xifeng county，Kuandian county and Huanren county of Liaoning province boast a superior ecological environment and abundant resources of mountain cultivated P. ginseng. The survey gets the whole picture of the ecological environment and associated plants of mountain cultivated P. ginseng in representative areas of Liaoning province，so as to provide the basis for the further development of mountain cultivated P. ginseng cultivation industry and the promotion of mountain cultivated Panax ginseng economy.
