Abstract：In order to screen out suitable interplanting patterns for Carya illinoensis young forests,in the study of 5-year-old Carya illinoensis trees,the effects of Carya illinoensis-Salvia miltiorrhiza,Carya illinoensis-Blackberry lily and Carya illinoensis-Platycodon grandiflorum on soil nutrient content and enzyme activity were investigated.The results showed that the influence of Salvia miltiorrhiza,Blackberry lily and Platycodon grandiflorum on soil hydrolyzable nitrogen,effective phosphorus,quick potassium,organic matter and the activity of urease,phosphatase,sucrase,catalase had significant changes.Compared with the uninterplanting control in November,the soil hydrolyzable nitrogen,quick potassium and organic matter content increased after interplanting Salvia miltiorrhiza and Blackberry lily,the change trend of effective phosphorus content was basically the same in different periods,and the content in November was lower than that of the uninterplanting control.The activities of soil urease,phosphatase and catalase increased,the activities of sucrase decreased after interplanting,and the change trend of soil urease and sucrase activities was basically the same in different periods.Overall,it could be seen that interplanting Salvia miltiorrhiza or Blackberry lily in the Carya illinoensis forest could facilitate the improvement of soil nutrient nutrient content and enhance the enzyme activity.
