摘  要:
本文通过有机肥磷素分级,对有机肥的水溶性磷与易溶性磷进行实验研究,目的是为研究有机肥的面源污染潜力提供理论依据。试验结果表明:有机肥全磷含量普遍较高,易于溶解流失的水溶磷及易溶磷含量分别占全磷的20%和40%左右,具有很高的含量。溶解态磷中,无机磷占80%左右。因此有机肥的过量施用对农业面源污染具有很大的影响。

摘  要:
The experimental study were conducted on water-soluble and diffluent phosphorous in organic fertilizer through phosphorous classification of organic fertilizer so as to provide theoretical basis for studying the non-point source pollution potential of organic fertilizer.The results showed that the total phosphorous content in organic fertilizer was higher generally,the contents of water-soluble and diffluent phosphorous which were easy to dissolve and lose were very high and were about 20% and 40% of total phosphorous.The inorganic phosphorous was about 80% of dissolved phosphorous.So,the excessive application of organic fertilizer had very big influence on agricultural non-point source pollution.
