广东不同产地香蕉园土壤养分吸附特性研究

Evaluation on characteristic of adsorbing of banana plantation soil nutrient from different producting in Guangdong province

应用土壤养分状况系统研究法,对广东省雷州半岛和粤西地区典型蕉园土壤进行土壤养分吸附特性研究。结果表明,雷州半岛砖红壤对磷、钾、硼和锌的平均吸附率分别为69.2%、24.3%、52.9%和26.7%,粤西地区蕉园土壤对磷、钾、硼和锌的平均吸附率则分别为43.9%、17.0%、39.8%和22.5%,整体上广东蕉园土壤对硫的吸附能力均很低。可见,蕉园土壤对磷、硼的吸附能力较强,对钾和锌的吸附较弱。但不同产区蕉园土壤对养分的吸附固定能力不同,雷州半岛蕉园砖红壤对磷、钾、硼和锌的吸附能力要强于粤西蕉园土壤。

The soil nutrient systematic study method was employed in this paper to study the characteristics of soil nutrient adsorption in Leizhou peninsula and western Guangdong areas in Guangdong banana plantation.Results showed：In Leizhou peninsula areas,the latosol adsorption rate to phosphorus,potassium,boron and zinc was 69.2%,24.3%,52.9% and 26.7% respectively.But in the western Guangdong areas,the soils adsorption rate to phosphorus,potassium,boron and zinc was 43.9%,17.0%,39.8% and 22.5% respectively.In general,all soils had low adsorption rate to S.The soils of banana plantation were high adsorption rate to P and B but low to K and Zn.However,the soil varied sharply in adsorbing capacity to nutrient in different producting area,the adsorbing capacity of latosol soils were significantly stonger than that in western Guangdong areas soils.
