老参地问题是制约参业发展的重大难题 ,笔者在总结前人关于老参地研究成果和经验的基础上 ,采取了测土施肥、有益微生物菌剂处理、酸碱度调整等土壤处理方法 ,成功地实现了老参地的短期再利用 ,建立了周期为 1～ 3年的人参和西洋参的短期轮作体系。在处理后的老参地上种植西洋参 ,其长势、产量、病虫害及烧须情况、总皂苷含量等 ,与对照地新林土栽参无显著差异 (P >0 0 5 )。并开展了中试规模的推广 ,试验结果显示 ,老参地短期轮作制是改造老参地的有效措施之一 ,该轮作技术方法应用简便、实用 ,可操作性强 ,轮作效果好。
The problem of old ginseng is a major problem restricting the development of the industry. On the basis of summarizing the predecessors’ research achievements and experiences of old ginseng, the author has taken soil treatment methods such as soil fertilization, beneficial microbial agent treatment, pH adjustment and so on. Short-term reutilization of old ginseng land was realized, and a short-term rotation system of ginseng and American ginseng with a period of 1 to 3 years was established. There was no significant difference (P> 0.05) in the growth of American ginseng grown on the treated old ginseng with its growth, yield, pest and disease, the content of total saponin and so on. The test results show that the short-term rotation system of old ginseng is one of the effective measures to transform old ginseng land. The technical method of this rotation is simple, practical and practical, and the rotation effect is good.
