is widely sought-after in China as a substitute for the more expensive ginseng. Continuous cropping of supports a vibrant health-supplement industry but requires significant inputs of fertilizers which increase production costs and degrade the environment.
Here, three environmentally-friendly natural fertilizers, including biochar, bacterial fertilizer, and vermicompost, were used at different concentrations (undiluted, diluted 10 times, diluted 50 times) to determine their efficacy in seed germination and growth physiology of in continuous cropping.
The results showed that biochar, bacterial fertilizer, and vermicompost with different concentrations of leachate could all increase the germination rate, germination potential and germination index of seeds treated with inter-root soil leachate of continuous ; increase the activity of antioxidant enzymes (superoxide dismutase and peroxidase) in seedlings under the stress of inter-root soil leachate of continuous , reduce the over-accumulation of malondialdehyde (MDA) content, and increase the resistance of seedlings. After transplanting, superoxide dismutase (SOD) activity increased by an average of 16.1%. Peroxidase (POD) levels showed an average increase of 16.4%. Additionally, there was a significant reduction in the MDA content, with an average decrease of 50%, and the content of osmotic-regulating substances (free proline content and soluble protein content) exhibited a significant increase.
In conclusion, biochar, bacterial manure, and vermicompost have the potential to overcome the challenges of extensive fertilizer use in continuous cropping of .
在中国，它作为更昂贵的人参的替代品而广受欢迎。连续种植它支撑起了一个充满活力的健康补充剂产业，但需要大量的肥料投入，这增加了生产成本并破坏了环境。
在此，使用了三种环境友好型天然肥料，包括生物炭、菌肥和蚯蚓堆肥，以不同浓度（未稀释、稀释10倍、稀释50倍）来确定它们在连续种植的[作物名称]种子萌发和生长生理方面的功效。
结果表明，不同浓度渗滤液的生物炭、菌肥和蚯蚓堆肥均能提高连续[种植情况]根系间土壤渗滤液处理的[作物名称]种子的发芽率、发芽势和发芽指数；提高连续[种植情况]根系间土壤渗滤液胁迫下的[作物名称]幼苗中抗氧化酶（超氧化物歧化酶和过氧化物酶）的活性，降低丙二醛（MDA）含量的过度积累，增强[作物名称]幼苗的抗性。移栽后，超氧化物歧化酶（SOD）活性平均提高16.1%。过氧化物酶（POD）水平平均提高16.4%。此外，MDA含量显著降低，平均降低50%，渗透调节物质（游离脯氨酸含量和可溶性蛋白含量）显著增加。
总之，生物炭、菌肥和蚯蚓堆肥有潜力克服[作物名称]连续种植中大量使用化肥的挑战。
