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。近年来随着我国农业生产中施用磷肥的大量增加,对 The factors affecting the fertilizer efficiency, the most important of which is the soil conditions. The effect of applying phosphate fertilizer depends on the amount of available phosphorus in the soil and on the soil properties that interact with the phosphate fertilizer, such as causing the dissolution of poorly soluble phosphates or immobilizing the phosphate. In recent years, with the large increase in the use of phosphate fertilizer in agricultural production in our country,
