通过对4龄芒果园间作体系前期水土流失研究表明

热带地区坡地芒果园水土流失严重

在试验条件下

果园不同间作生态系统中

芒果柱花草间作模式的径流量和泥沙流失量分别为13747.9m3/hm2

6881.0kg/hm2;芒果木薯间作模式的径流量和泥沙流失量分别为11199.3m3/hm2

5105.6kg/hm2

单作芒果的径流量和泥沙流失量分别为10590.5m3/hm2

4440.3kg/hm2

芒果蕃薯-花生间作模式的径流量和泥沙流失量分别为8701.5m3/hm2

3741.3kg/hm2。养分物质损失量大小顺序为有机质>速效钾>全氮>水解氮>速效磷。养分流失呈现明显的季节性变化。
