海河流域１４种农作物平均含磷量为０．１２７±０．０５３％，变化范围０．０２３－０．２１４％，不同器官中最高可达０；４１９％，最低汉为０．０１９％。对土壤库中磷输出量最大者为谷子，磷可达９９．７５８±５６．９３１ｋｚ·ｈａ￣（－１）·ａ￣（－１），其次是玉米和棉花；磷输入量以白薯为最大，为１２．５５７±５．０２０ｋｇ·ｈａ￣（－１）·ａ￣（－１）（但包括可食部分块根的输出部分在内）．然后是谷子和花生，其余作物均较低，＜２ｋｇ·ｈａ￣（－１）·ａ￣（－１）。具高输出量的作物的部位有玉米、谷子、花生、棉花等果实，谷子、花生、白薯等茎叶；就输入量而言，除白薯为高输入和谷子为低输入类型外，其余均属很低输入型，上述特点揭示了海河流域因作物的收获而大量损失土壤库中的磷，如种植谷子、玉米、棉花等分别以９９．７５８、３２．６６１和２６．５９１ｋｇ·ｈａ￣（－１）·ａ￣（－１）的速率损失有效态磷。并对不同子流域作物磷的输出（入）量差异以及针对上述问题应采取的对策作了探讨。
The average phosphorus content of 14 kinds of crops in the Haihe River Basin was 0.127 ± 0.053%, ranging from 0.023% to 0.214%. The highest content of phosphorus in different organs was 0%, 419%, and the lowest Han was 0.019%. The maximum phosphorus output in the soil bank was millet with phosphorus up to 99.758 ± 56.931kz · ha -1 (-1) · a -1, followed by corn and cotton, and phosphorus input was the largest with sweet potato , 12.557 ± 5.020 kg · ha -1 (-1) a -1 (but including the output of the edible part roots). Then millet and peanut, the remaining crops are low, <2kg · ha ~ (-1) · a ~ (-1). The crops with high output were corn, millet, peanut, cotton and other fruits, millet, peanut, sweet potato and other stems and leaves. In terms of input, sweet potatoes were high-input and low-input of millet, Low input type, the above characteristics reveal that the Haihe River Basin due to crop harvest and a lot of soil phosphorus loss, such as planting millet, corn, cotton, respectively 99.758,32.661 and 26.591kg · ha ~ (- 1) · a ~ (-1) at the rate of loss of available phosphorus. The differences in output (input) of crop phosphorus in different sub-basins and the countermeasures that should be taken to address these problems were discussed.
