热带不同母质香蕉园土壤理化性状比较研究

A Comparison Study of Soil Physical and Chemical Properties in Banana Gardens from Different Parent Materials in Subtropical

通过对热带不同母质香蕉园土壤理化性状的分析,结果表明:①玄武岩母质发育的香蕉园土壤全钾含量比冲积土的低88.2%,有机质、全氮和全磷含量比冲积土的分别高86.1%,42.1%和153.7%。②玄武岩发育的香蕉园土壤碱解氮和速效钾含量比冲积土的分别高124.5%和48.0%,速效磷减少32.1%。③玄武岩发育形成的土壤脲酶、酸性磷酸酶、蔗糖酶和过氧化氢酶活性比冲积土的分别高20.3%、121.0%、122.2%和11.9%。④热带香蕉园土壤速效磷和速效钾含量出现明显富集现象,玄武岩和冲积土发育形成的香蕉园土壤速效磷分别比对照土壤提高了1124%和602.9%;土壤速效钾含量分别比对照的提高了502.9%和255.8%。

Pass the analysis to the soil physics and chemistry properties in banana gardens form different parent materials in subtropical, The results showed as following： ①Soil 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. ②Soil 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%.
