野生草麻黄对土壤酶活性及活性有机碳的影响
The Effect of Wild Ephedra sinica on Soil Enzyme Activity and Active Organic Carbon
摘要
Abstract
Objective:To study the effect of Ephedra sinica on the soil enzyme activity and active organic carbon,reveal the utilization mechanism of Ephedra sinica to soil nutrient,and to provide theoretical support to artificial cultivation technology.Methods:The effect of Ephedra sinica on the soil enzyme activity and active organic carbon in the soil of corn field and the soil of open land were studied by the comparison of the soil with different densities of wild Ephedra sinica in dryland farming areas of Hebei Province.Results:The soil catalase activity in wild Ephedra sinica field was significantly lower than that in the open land,but higher than that in the corn field.The urease activity and invertase activity in wild Ephedra sinica field was significantly higher than that in the open land.With the density and biomass of wild Ephedrae sinica increasing,the soil catalase activity and urease activity showed a downward trend,the invertase activity showed the trend of first increased and then decreased.The total organic carbon (TOC) content in wild Ephedra sinica soil was significantly higher than that in the open land,but the active organic carbon (AOC)content was lower than that in the open land.With the increasing of the wild Ephedra sinica density and biomass,the TOC content showed the trend of first increased and then decreased,and the AOC content showed the trend of first decreased and then increased.Soil pH value showed extremely significant positive correlation with catalase,while significantly negative correlation with urease,extremely significant positive correlation with AOC,and significantly positive correlation with AOC/TOC.The invertase activity showed significantly positive correlation with TOC,and showed a significantly negative correlation with AOC/TOC.Conclusion:Ephedra sinica through root exudates and debris shedding affect the change of soil TOC components,pH value and enzyme activity,and then promotes the soil nutrient cycling and to adapt to the poor environmental condition.Ephedra sinica high yield cultivation is adapt to the nutrient conversion faster sandy loam.关键词
