通过盆栽试验，研究了肥料与石膏配施条件下滨海盐土有效磷变化特征，结果表明，（1）不同肥料与石膏配施条件下，滨海盐土有效磷含量以有机无机复混肥（F2）处理较高，而以单施石膏2g／kg（V0B2）处理较低。（2）磷肥施用可显著提高滨海盐土有效磷含量，供试肥料品种间滨海盐土有效磷含量以有机无机复混肥处理（F2）、无机复混肥（F1）处理最高，其次为生物有机无机复混肥（F4）和生物有机肥（B），以空白对照（Fo）最低。（3）随石膏用量增加，土壤有效磷呈显著降低趋势。（4）滨海盐土有效磷含量存在明显动态变化特征，肥料施用后有效磷总体上呈现先增加后降低趋势，最终回复到施肥前水平。（5）从土壤有效磷角度考虑，滨海盐土肥料农业施用以有机无机复混肥（F2）较为适宜。

The variation characteristics of the available phosphorus （P） in coastal saline soil under combined ap- plication of fertilizer and gypsum were studied by pot experiments. The results showed as follows. （ 1 ） The soil available P content of organic - inorganic compound fertilizer （ F2 ） treatment was higher than other treatments, and that of single application of 2g/kg gypsum （F0 B2 ） treatment was lower. （2） Application of phosphate fertil- izer could significantly increase the available P contents in coastal saline soil. The order of soil P contents of the tested fertilizer varieties was organic and inorganic compound fertilizer （F2 ） and, inorganic compound fertilizer （F,）〉 bio -organic and inorganic compound fertilizer （F4） and bio -organic fertilizer （F3 ）〉 blank control （F0）. （3） With the increased use of gypsum, soil available phosphorus contents were remarkably decreasing. （4） The contents of available P in coastal saline soil had obvious dynamic change. With the addition of fertilizer application, the available P contents presented increasing firstly, then decreasing, and finally back to the levels before. （5） From the view of soil available P, the treatment of organic and inorganic compound fertilizer （ F2 ） was appropriate to agricultural application in coastal saline soil.
