There are serious soil sickness in ginseng cultivation. Crop rotation is an effective agricultural management to improve soil sustainability and reduce soil sickness. To explore an appropriate ginseng rotation system, (alfalfa) and (perilla) were planted on ginseng cultivation soil for 1 year to evaluate the improvement effect of both. Through chemical analysis and high-throughput sequencing technology, we found that after alfalfa and perilla cultivation for one-year, various nutrients and enzyme activities in ginseng cultivation soil were significantly improved. In addition, perilla significantly increased the diversity and richness of soil fungal communities. Cultivation of alfalfa and perilla significantly changed the composition of soil bacterial and fungal communities and significantly reduced the abundance of the potentially pathogenic fungi . Further pot experiments also showed that the improved soil could significantly increase root activity of ginseng plant after two plants were planted. It should be noted that, unlike alfalfa, perilla decreased soil electrical conductivity, increased soil organic matter, soil urease, and may significantly improve the diversity and richness of soil fungal community. Moreover, in the pot experiment, the root fresh weight of ginseng cultured in perilla treated soil increased significantly. This study highlights that perilla may have better soil improvement effect than alfalfa and it has the potential to be used in the soil improvement of ginseng cultivation.
人参种植中存在严重的土壤病害问题。轮作是提高土壤可持续性和减少土壤病害的一种有效农业管理措施。为了探索合适的人参轮作体系，将紫花苜蓿和紫苏种植在人参种植土壤上1年，以评估二者的改良效果。通过化学分析和高通量测序技术，我们发现紫花苜蓿和紫苏种植1年后，人参种植土壤中的各种养分和酶活性显著提高。此外，紫苏显著增加了土壤真菌群落的多样性和丰富度。紫花苜蓿和紫苏的种植显著改变了土壤细菌和真菌群落的组成，并显著降低了潜在致病真菌的丰度。进一步的盆栽试验还表明，种植这两种植物后，改良后的土壤能显著提高人参植株的根系活力。需要注意的是，与紫花苜蓿不同，紫苏降低了土壤电导率，增加了土壤有机质、土壤脲酶，并且可能显著提高土壤真菌群落的多样性和丰富度。此外，在盆栽试验中，在紫苏处理过的土壤中培养的人参根鲜重显著增加。本研究强调，紫苏可能比紫花苜蓿具有更好的土壤改良效果，并且有潜力用于人参种植的土壤改良。
