橡胶间种砂仁、咖啡对土壤肥力的影响杨曾奖，郑海水，尹光天，周再知，陈土王，陈康泰关键词橡胶，砂仁，咖啡，胶园间种，土壤肥力地处雷州半岛东海岸的南华农场，在胶园立体种植多层次栽培模式上进行了探索。１９７５年以来，由于逐步发展壳砂仁、咖啡等经济作物，至目...
An investigation on soil status was carried out in three different agroforestrymodels
namely,Rubber tree +Amomum villosum,Rubber tree +Coffee tree and pure
rubberplantation.From the investigation of soil water,soil fertility,soil aeration and soil
tempera-ture,it showed that no significant influence on soil fertility was found in the rubber
planta-tion intercropping with coffee tree,while intercropping with Amomum villosum,whic is
favor-able to increase soil fertility.Taking pure rubber plantation as a control,in the soil
layerwithin 0～40 cm,the mean soil organic matter content increased by 2.28 g/kg,total
nitro-gen increased by 0.15g/kg,available phosphorus increased by 2.0mg/kg and
availablepotassium increased by 20.8mg/kg in the rubber plantation intercropping with
Amomum vil-losum.The soil structure and water and soil conservation properties have also
been improvedand 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 3.8cmol(+)/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
temperaturewhich provides favorable condition for retention of the soil organic matters.The
same resultwas obtained by means of quantification for comprehensive evaluation of different
fertilityfactors of soil.
