Abstract: In order to reveal the mode of papaya-stylosanthes on soil nutrients, sampling and nutrient analysis of soil nutrients in different planting patterns were carried out. The results showed that intercropping and cover stylosanthes could increase the content of soil organic matter and available nitrogen, cover could increase the content of soil available P and K. In papaya-stylosanthes mode, available P and K content decreased, the number of soil microorganism and organisms increased.
