通过监测传统胶园与全周期种植模式胶园土壤的养分差异，探讨全周期种植方式对胶园土壤养分的影响。结果表明，传统胶园内离树越近的位点，土壤养分含量和微生物量碳越低；除速效磷外，全周期胶园内离树越近的位点，土壤养分含量和微生物量碳越高。总体而言，全周期胶园土壤全氮、无机氮和微生物量碳低于传统胶园，但均没有达到显著差异，而其土壤有机质、速效磷和速效钾含量高于传统胶园，其中速效磷含量达显著差异(P＜0.05)。与传统胶园相比，全周期种植模式主要影响土壤养分和微生物量碳的分布特征，其中土壤速效磷和速效钾含量亦相对较高，其他指标变化较小。

The objective of this study was to reveal the effect of planting pattern of whole production cycle on soil nutrient and micro biomass carbon, by comparing conventional (C) and the whole production cycle intercropping (I) rubber plantation. Results showed that, the closer to rubber trees, the lower content of soil nutrient and micro biomass carbon in C rubber plantation. Except available phosphorus, the closer to rubber trees, the higher content of soil nutrient and micro biomass carbon in I rubber plantation. Totally, soil total N, inorganic N and micro biomass carbon in I rubber plantation were lower than those in C rubber plantation, but there were no significant difference, while soil organic matter, available phosphorus and potassium were higher than those in C rubber plantation. Available phosphorus in I rubber plantation was significant higher than in C rubber plantation (P<0.05). Compared to C rubber plantation, planting pattern of whole production cycle mainly affected the distribution characteristic of soil nutrient and micro biomass carbon in rubber plantation. Higher content of available phosphorus and potassium were also found in I rubber plantation, while other factors changed slightly.
