| 摘 要： | 影响磷肥肥效的因素,其中最为重要的是土壤条件。施用磷肥效果的大小,既取决于土壤中可给态磷的含量,也决定于与磷肥相互作用的土壤性质,如引起难溶性磷酸盐的溶解,或可给态磷酸盐的固定等特点。

| Abstract: | The potential of phosphorus supply is higher in soil of plain region than those oecurring on hilly land in Liaonillg Provillce.The rate of response of crop yield to phosphatic fertilizer showed no definit correlation with the content of total phosphorus and organic phosphorus,but was highly correlated with the content of available phosphorus.The order of eontent of available phosphorus in neutral and weak acid soil is as follows:Meadow soil>Alluvial soil>Brown earth.As for tlle calcareous soils,the order is:Saline soil>Calcareous meadow soil>Cinnamon soil. |
