通过盆栽试验研究了芋头植株的干物质积累动态和氮、磷、钾的吸收特性。结果表明芋头植株体内氮、磷、钾的吸收量与干物质积累均呈S型曲线。苗期芋头对氮、磷、钾的吸收均很少,吸收盛期出现在出苗后的60～110天。芋头对氮、钾的吸收强度均呈单峰曲线,最高峰分别出现在出苗后的98天和104天。对磷的吸收强度呈双峰曲线,高峰期分别出现在出苗后的86天和98天。
The pot experiment was conducted to study the dynamic changes of dry matter accumulation and the absorption characteristics of nitrogen, phosphorus and potassium in taro plants. The results showed that taro plants in the body of nitrogen, phosphorus and potassium absorption and dry matter accumulation showed S-curve. Taro seedling nitrogen, phosphorus, potassium absorption are few, absorption peak appears in the emergence of 60 to 110 days. Taro nitrogen and potassium absorption intensity showed a single peak curve, the highest peak appeared in the emergence of 98 days and 104 days. The absorption intensity of phosphorus showed a bimodal curve, the peak appeared in the post-emergence of 86 days and 98 days.
