Abstract: An investigation on soil status was carried out in three different agroforestry models namely,Rubber tree+Amomum villosum,Rubber tree+Coffee tree and pure rubber plantation.From the investigation of soil water,soil fertility,soil aeration and soil temperature,it showed that no significant influence on soil fertility was found in the rubber plantation intercropping with coffee tree,while intercropping with Amomum villosum,whic is favorable to increase soil fertility.Taking pure rubber plantation as a control,in the soil layer within 0～40 cm,the mean soil organic matter content increased by 2.28 g/kg,total nitrogen increased by 0.15g/kg,available phosphorus increased by 2.0mg/kg and available potassium increased by 20.8mg/kg in the rubber plantation intercropping with Amomum villosum.The soil structure and water and soil conservation properties have also been improved and increased.In the 0～10 cm soil layer,absolute capacity of the soil waterstable aggregateof 2～5mm soil grain increased by 18.8%,soil cation exchange capacity increased by 3.8 cmol(+)/kg and the absolute capacity of soil moisture in dry season increased by 70.0g/kg.The rubber plantation intercropping with Amomum villosum has lower soil temperature which provides favorable condition for retention of the soil organic matters.The same result was obtained by means of quantification for comprehensive evaluation of different fertility factors of soil.
