对福建省 781个柑橘园和 315个龙眼园的土壤进行分析 .结果表明 ,这 2种果园多数的土壤有机质质量分数处于良好水平 ;土壤有机质质量分数与有效性养分质量分数关系密切 ;土壤有效性养分质量分数随有机质质量分数的增加而增加 ;柑橘园与龙眼园土壤的有机质质量分数分别为 15- 35和 10 - 30 g· kg-1,其土壤有效性养分质量分数较为适宜 .因此 ,上述 2种果园的土壤有机质质量分数可作为较为适宜范围 .
Soil samples of 781 citrus orchards and 315 longan orchards in Fujian Province were analyzed.The results showed that most of the two kinds of orchards had good soil organic matter (OM) content, soil organic matter (OM) and nutrient availability The mass fraction of nutrients increased with the increase of organic matter mass fraction, and the organic matter mass fractions of citrus orchard and longan orchard were 15-35 and 10-30 g · kg-1, respectively, Soil organic matter mass fraction of two orchards can be used as a more suitable range.
