Soil physical and chemical properties in Rhodolcia championii stands with different densities(1 667

2 500

4 444

and 10 000 trees/hm2)were determined using conventional methods to utilize soil resources reasonably.Compared with other stands

soil bulk density in the stand of 10 000 trees/hm2 was great and its aeration ability was weak.Contents of soil organic matter

N

P

and K in the stand of 2 500 trees/hm2 were high among the four stands

indicating that its effect on soil improvement was better than the other stands.In the stand of 4 444 trees/hm2

soil organic matter and N contents were relatively high

P content was medium

and K content was high.The result indicated that the stand was favorable for soil nutrient accumulation.In the stand of 1 667 trees/hm2

soil organic matter and N contents were medium

P content was high

and K content was relatively low.As a result

the stand significantly improved soil P condition.Contents of soil organic matter

N

P

and K in the stand of 10 000 trees/hm2 were low

which indicated that the stand was unfavorable for soil nutrient accumulation.
