采用分光光度法测定西瓜地土壤中的有效磷，结果表明：其操作简单、快捷、取样方便，线性关系良好，1号、4号、7号、8号瓜棚中西瓜长势、外观品质均较其他棚欠缺，与其土壤中有效磷含量有一定关系，试验结果可作为当地瓜农施用磷肥和氮肥的依据。

Determination of phosphorus by spectrophotometry in watermelon soils was measured.The results showed that spectrophotometry had some advantages including simple, fast, convenient sampling and a good linear relationship. Watermelon in the 1st, the 4 th, the 7 th and the 8 th greenhouse were lack of quality,for example growingand appearance.Its phosphorus content in soil had a certain relationship.With the results,it could be used as a local application basis of phosphate and nitrogen.
