Abstract: : According to the analysis to the soil physics and chemistry properties in banana gardens form different parent materials in subtropical, the results showed as following: ① Soil total potassium content of the banana gardens from basalt were decreased by 88.2% than alluvial soil’s, content of organic matter, total nitrogen and total phosphorus were increased by 86.1%, 42.1% and 153.7% than those from alluvial soil. ② Soil alkaline nitrogen N and available potassium of the banana plantation from basalt were increased by 124.5% and 48.0% than those from alluvial soil, available phosphorus reduces 32.1%. ③ The activities of soil urease, acid phosphatase, sucrase and catalase were higher than those from alluvial soil by 20.3%, 121.0%, 122.2% and 11.9%. ④ Soil available potassium and available phosphorus in banana plantation are enriched obviously, available potassium of the banana plantation from basalt and alluvial were increased by 515.5%和255.8% than control’s. Available phosphorus were increased by 1124%和602.9%.
