We all know that the quality of soil nutrients will directly affect the production status of plants and crops, and soil nutrients will affect the local soil fertility. The soil nutrient speed meter can quickly and accurately determine the status of soil nutrients. Camellia is one of the important traditional industries in Lishui City. There are large areas of Camellia oleifera forest land in Qingtian, Suichang, Jinyun, Songyang and other counties. During the growth and development of Camellia oleifera, soil fertility is an important factor. The variation of the main mineral elements in the soil is of great significance in guiding the application of fertilizers and tea management. Through the analysis and research on soil nutrient status of Camellia oleifera forest in some areas of Lishui, the laws of soil fertility development of Camellia oleifera forest under various operating conditions were discussed, which provided a reference for soil health evaluation of Camellia oleifera forest, fertilization of Camellia oleifera forest land, and comprehensive benefit of low-yield forest. At present, the management of Camellia oleifera forest in Lishui is generally adopted a relatively modest management model. The disturbance and impact on soil is smaller than that of intensive bamboo forests such as bamboo shoots, and soil nutrient variability is relatively small. The pH value of Camellia oleifera forest reached the level of weak variability, organic matter, alkali-hydrolyzed nitrogen, available phosphorus, and available potassium reached moderate variability level, and the degree of variation was expressed as available phosphorus> organic matter> alkaline hydrolysis nitrogen> available potassium. In the soil profile of Camellia oleifera, the contents of various nutrients have obvious levels, the content of surface nutrients is highest, and it shows a downward trend. This is in association with the accumulation of litter in soil surface plants and provides a large amount of organic nutrients to the soil. The root layer of oil tea (5-30 cm) is absorbed by the roots and the soil nutrients are consumed, resulting in a change in soil nutrient content in the profile. However, the soil pH did not change significantly in the profile. Different nurturing measures have a certain influence on soil nutrient content in Camellia oleifera forest. In terms of soil organic matter, available nitrogen, available phosphorus, and available potassium, Yufu forestland> Yushan forest land> uncultivated forest land, which indicates that artificial remediation can improve soil nutrient status and effectively increase soil nutrient content. The effect of improving the soil nutrient content in the recultivation of the alfalfa is significantly higher than that of the Laoshan tending. However, there was no significant effect on the pH value of the soils in Fufu and Lushan.
