海南植胶区部分胶园土壤有效钼含量及其影响因素分析
Analysis on content of soil-available molybdenum and its influencing factors in some plantations in Hainan rubber planting areas
摘要
Abstract
The distribution of soil梐vailable molybdenum(Mo) and its influences in some rubber plantations in Hainan were researched in order to provide references for the rubber industry development. [Method]The content of soil梐vailable molybdenum in some rubber plantations in Hainan were studied by relevant soil sampling, investigations, and laboratory tests. [Result]The contents of soil梐vailable molybdenum ranged from 0.01 to 0.76 mg/kg, and the average was 0.033 mg/kg. The low-level-Mo rubber plantations accounted for 64.55% of the total investigated plantations, rubber plantation with medium條evel accounted for only 3.79%, and high條evel桵o rubber plantations only account for 0.2%. The correlation coefficient between soil pH and available Mo was 0.062 with the associated probability of 0.166; the correlation coefficient between soil organic matter and available Mo was 0.043 with the associated probability of 0.331. [Conclusion] The soil-available Mo in rubber plantations lacked severely; the soil organic matter and pH values did not have significant effects on the available molybdenum contents in the rubber plantations. The available molybdenum contents in rubber plantations soil formed with different parent materials differed; the Mo content was the highest in soils formed with balsalt parent material, while the Mo content was the lowest in soils formed with sand shale parent material.关键词
