| Abstract: | Based on the investigation and sampling analysis,the results showed that the tendency of petrification and desertification in soil surface layer was remarkable in Hainan's pineapple orchards.When a comparison was made between the sample soil and the contrast soil,the content of organic matter,total nitrogen,alkaline nitrogen,and quick acting potassium in sample soil obviously showed the tendency of decline.But the content of phosphorus and total potassium didn't show the tendency of decline. |
