| 摘 要： | 试验采用广东东莞花岗岩发育的坡地赤红壤为样品进行研究表明 :在坡地赤红壤的 4种利用模式中 ,旱地种植花生 ,荔枝可以有效地改善土壤的酸性 ,提高土壤肥力 ;提高土壤Al-P和Fe -P的含量 ,减少O -P的所占的比例 ,提高坡地赤红壤磷酸盐的有效性 ;增加土壤表层的脲酶和蛋白酶的活性 ,可能使土壤的磷酸酶的活性降低

| Abstract: | Four land utilization models in lateritic red soil of slope land in Dongguan city, Guangdong province were studies in this paper. The results showed that peanut and lichi model can effectively increase soil acidity, and heighten soil fertility, which can increase the content of Al-P and Fe-P,decrease the content of O-P,and enhance the phosphate validity of lateritic red soil, which can increase the urease and protease activities in surface soil,while may reduce the soil phosphatase activity. |
