基于土壤微生物群落结构的参地土壤改良研究进展

Progress of Soil Improvement in Ginseng Soil Based on Soil Microbial Community Structure

改良参地土壤是缓解参地资源紧缺、促进人参种植业健康持续发展的有效途径。综述土壤微生物群落结构改变与连作障碍关系,参地土壤化学消毒、农业改良和微生物防治对土壤微生物的影响。结果显示:微生物制剂可以通过调整土壤微生物群落结构、拮抗病原菌、激活养分等有效防治人参病害及改良参地土壤;开发高效、具有广谱抑菌活性的微生物混合菌剂,辅以化学消毒、农业改良等土壤改良技术是改良参地土壤及防治人参病害的关键。

Improving ginseng soil is an effective way to alleviate the shortage of ginseng soil resources and promote the healthy and sustainable development of ginseng planting industry.The relationship between changes in soil microbial community structure and continuous cropping obstacles,the effects of chemical disinfection,agricultural improvement and microbial control of ginseng soil on soil microorganisms were reviewed.The results showed that microbial preparations could effectively control disease and improve ginseng soil by adjusting soil microbial community structure,antagonizing pathogenic bacteria and activating nutrients.The key to improve ginseng soil and control ginseng disease is to develop a mixture of highly efficient and broad-spectrum microbial bacteriostatic agents,and to supplement it with soil improvement techniques such as chemical disinfection and agricultural improvement.
