Title: Fertility Evaluation and Spatial Distribution Characteristics of Soil Nutrients of Rubber Plantations in Hainan Wushi Farm
Abstract: To provide a decision basis for rational fermentation and nutrient management of soil in rubber plantations in rubber plantation in Hainan Wushi Farm,taking the soil nutrients as the research object,the fertility evaluation and spatial characteristics of soil nutrients were studied by using many methods such as fuzzy mathematics,Delphi method,analytic hierarchy process,comprehensive index method and cumulative curve methods etc.Results:the soil fertility levels of rubber plantations in Wushi Farm could be divided into five grades,the second and third grades accounted for 79%and the soil fertility level was above the average grade.However,the spatial distribution of each grade rubber plantation was more dispersed basically,and had distribution in every production team;the soil acidity of rubber plantation was very strong and soil organic matter,total nitrogen,available phosphorus,available potassium and the concentrations of exchangeable calcium and magnesium were at a lower level in general
