对2种生长模式的人参5种有效成分和6种土壤酶活性进行测定,运用典型相关分析方法对数据进行了分析,以期阐明它们之间的关系。结果表明,土壤酶活性与人参有效成分密切相关,相同酶在腐殖土中的活性显著高于农田土。农田土生长模式下,土壤中的蔗糖酶活性和磷酸酶活性过高,会抑制人参总皂苷、水溶性总蛋白和总氨基酸的积累;腐殖土生长模式下,土壤蔗糖酶活性、脲酶活性和磷酸酶活性过高,会抑制人参总皂苷和总挥发油的积累。结合人参生长特征等因子进行综合分析,土壤酶活性可作为评价土壤质量的指标,合适的土壤酶活性,能够加速土壤各类物质的循环与转化,增加人参有效成分的积累。
Five kinds of active ingredients and six kinds of soil enzyme activities of two kinds of growth patterns were determined, and the data were analyzed by canonical correlation analysis to clarify the relationship between them. The results showed that soil enzyme activity was closely related to the active components of ginseng, and the activity of the same enzyme in humus soil was significantly higher than that of farmland soil. In the soil-grown soil model, the sucrase activity and phosphatase activity in the soil were too high, which inhibited the accumulation of total ginsenoside, water-soluble total protein and total amino acids. Under the growth of humus soil, the soil invertase activity, urease activity and Phosphatase activity is too high, will inhibit the accumulation of ginseng total saponins and total volatile oil. According to the comprehensive analysis of the growth characteristics of ginseng and other factors, soil enzyme activity can be used as an index to evaluate soil quality. Appropriate soil enzyme activity can accelerate the circulation and transformation of various soil materials and increase the accumulation of active ingredients in ginseng.
