Soil Enzyme Activity,Nutrient Characteristics of Different Kinds of Trees and Their Relationship with SHBI of Woodsgrown Ginseng Red Coating Root Disease
摘要
Abstract
Soil nutrient content and soil enzyme activity of three kinds of trees,Malus prunifolia,acer mono and elm,were detected and analyzed.Based on SHBI of woodsgrown ginseng red coating root dis-ease,multiple linear regression analysis was carried out.The results show that the content of soil avail-able phosphorus and available potassium under acer mono was the highest;available nitrogen content, peroxidase activity and phosphatase activity were the highest supreme under elm;organic matter content and sucrase activity were the highest under Malus prunifolia;soil enzyme and nutrient content under the same tree were higher than those on the tree,and the difference wad significant;there was positive corre-lation between SHBI of ginseng red coating root disease(Y)and organic content(X1),peroxidase activity (X3)and phosphatase activity(X5),and the coefficients of partial correlation were 0.927,0.902 and 0.934,respectively.There was negative correlation between SHBI of ginseng red coating root disease(Y) and available nitrogen(X6),phosphorus(X7)and potassium(X8),and the coefficients of partial correla-tion were -0.897,-0.863 and -0.942,respectively,the optimum fitting equation was Y =-1 .701 +0.075 X1 +4.849X3 +0.033X5 -0.005 X6 -0.010X7 -0.005 X8,R =0.978.The acer mono can re-duce SHBI of ginseng red coating root disease,therefore,it is more suitable for nursing woodsgrown gin-seng.关键词
