本文采用Bowman-Cole法,对1984和1986年吉林省农科院黑土定位试验各小区土样,进行了有机磷分组分析,并测定了土壤全磷和有效磷含量。分析结果表明:施用有机肥,首先使土壤相对活性有机磷和高稳态有机磷增加。然后再转化为其它形态的有机磷或无机磷。土壤有效磷和活性有机磷、相对活性有机磷及中稳态有机磷均呈显著相关。有机肥使石灰性土壤pH下降,磷的有效性提高。
In this paper, the Bowman-Cole method was used to analyze the soil samples of plots of various plots of the black soil of Jilin Academy of Agricultural Sciences in 1984 and 1986 and to analyze the contents of total phosphorus and available phosphorus in the soil. The results showed that: the application of organic fertilizer, the first soil relative activity of organic phosphorus and high steady-state organic phosphorus increased. And then converted into other forms of organic phosphorus or inorganic phosphorus. Soil available phosphorus and active organic phosphorus, relative active organic phosphorus and medium stable organic phosphorus were significantly correlated. Organic fertilizer decreased the pH of calcareous soil and increased the availability of phosphorus.
