以海南省文昌市典型的胶—茶—鸡农林复合模式为研究对象 ,以单作胶园、胶茶间作园为对照 ,采用定量研究与定性分析相结合的方法 ,研究其物质循环规律。结果表明 ,胶—茶—鸡农林复合系统的氮、磷输入、输出量最大 ,系统外物质投入率比另两系统明显减少 ,系统内养分循环量增加 ,因此 ,该系统具有较合理的物质循环结构。

Nutrient cycle of rubber tea chicken eco agricultural model—a typical tro pical agro forestry system in Wenchang municipality of Hainan Province was studied with quantitative experiment and qualitative analysis compared with rubber and rubber tea systems.Results showed that the cycling and outputting nutrient of chicken gardens were the highest and the nutrient cycle was most active.Its ratio of external N and P input decreased than the other two systems and the internal cycling nutrient increased,so,the rubber tea chicken agro forestry system has rational nutrient cycle structure.
