摘要

[Objectives] This study was conducted to analyze the current status of soil quality in Chongqing and provide scientific data for the rejuvenation of flowering cherry in the botanical park of the city. [Methods] With the flowering cherry soil in Chongqing Botanical Park as the research object, the typical soil in this area was investigated and improved. [Results] After applying soil conditioners, the pH value of the surface soil decreased from 7.32 to 6.34, and the pH value of the bottom soil decreased from 7.52 to 6.77;and the surface soil organic matter increased from 35.2 to 54.1 g/kg, and the bottom soil organic matter increased from 15.7 to 26.3 g/kg. [Conclusions] The soil has strong buffering capacity, and it is difficult to achieve rapid adjustment of soil pH and organic matter in actual work. Soil improvement needs to be carried out step by step. After targeted improvement, further maintenance is required in the later stage.
