In order to screen out the Camellia forest management models to promote yield, soil fertility at different depths layer were explored in the young Camellia forest interplanting with Vigna sesquipedalis, Glycine max ( Linn.) Merr., Vigna radiata ( Linn.) Wilczek, Arachis hypogaea Linn., Cassia rotundifolia Pers and Chamaecrista nictitans, and the grey relationgal analysis was used to analyze the effects of interplanting models on soil physical and chemical properties. The results showed that the young Camellia forest interplanting with leguminous plants can reduce soil bulk density at different depths layer, improve soil total porosity, drainage capacity and maximum moisture capacity, content of organic matter, total N, total K, total P, available N, available K and available P in different depths layer were improved in different level, and available N content increased by 12. 18%~32. 96%, available K content increased by 6. 85%~56. 58%, available P content increased by 1. 95%~78. 12%. Among them, Camellia+Cassia rotundifolia Pers is the best model to improve soil physical properties and soil nutrient effect, and followed by the model of Camellia+Vigna sesquipedalis or Chamaecrista nictitans.
