The relationship between soil microbial biomass and soil organic C and respiration in three different agroforestry models, namely rubber tree + Amomum villosum, rubber tree + Coffea arabica and pure rubber plantation was investigated. The results showed that mean soil microbial biomass under the three models is in the order: rubber tree + Amomum villosum > pure rubber > rubber tree + Coffea arabiea, and their Cmic content is in the range of 380.8~586.3 mg/kg dry soil. Higher microbial biomass in the model of...

The relationship between soil microbial biomass and soil organic C and respiration in three different agroforestry models, namely rubber tree + Amomum villosum, rubber tree + Coffea arabica and pure rubber plantation was investigated. The results showed that mean soil microbial biomass under the three models is in the order: rubber tree + Amomum villosum > pure rubber > rubber tree + Coffea arabiea, and their Cmic content is in the range of 380.8~586.3 mg/kg dry soil. Higher microbial biomass in the model of rubber tree +coffee was found in dry season than that in rainy season, while other two models are quite the opposite. It was also found that there were higher microbial biomass, shorter microbial transformation period and higher turnover rate in the soils of rubber forests intercropping with Amomum villosum and coffee than that in the pure rubber forest soil. Meanwhile, the ecological environment of the forests was greatly improved under the intercropping.

探讨了橡胶与砂仁、橡胶与咖啡间种和纯橡胶林3种栽培模式下的土壤微生物生物量及其与土壤有机碳和土壤微生物呼吸强度的关系。结果表明,在这3种模式下,土壤微生物生物量平均值由高到低的顺序为:橡胶+砂仁林地>纯橡胶林>橡胶+咖啡林地。其Cmic范围是380.8~568.3 mg/kg。橡胶+咖啡林地土壤微生物生物量在旱季高于雨季,而其余两种林地则在雨季较高。橡胶林间种作物后,林地土壤表现出比纯橡胶林地有较高的土壤微生物生物量和较短的土壤微生物的转化周期,年转化代数较多;同时,间种也大大改善了林内生态环境。
