| Abstract: |
| In order to find out the nutrient status,nutrient limiting factors and its deficiency-degree of the dry red soil in Hainan banana garden,the method of systematic study on soil nutrition is employed to analyze the nutrient status of dry red soil in Hainan banana garden.The results show that:(1)The order of adsorption fixed ability by dry red soil on various nutrients is:B>P>Cu>Zn>S>K;(2)The dry red soil in banana garden of the country of Ledong,Hainan Province lacks N,P,K,Cu and Mo,but does not lack Fe,Mn,Ca or Mg. |
| Key words: limiting factor,dry red soil,systematic approach,banana garden |
