中文摘要	通过室内培养方法，研究外源磷不同用量及腐植酸施用方式对灰漠土有效磷含量的影响。结果表明:随外源磷用量增加，土壤有效磷含量先增大后减小，土壤固磷率先增后减再增大，有效磷含量在土壤中有一个极大值平衡点;腐植酸及外源磷施用方式对土壤有效磷含量影响较大，单施腐植酸或单施外源磷均可增加土壤有效磷含量，且效果显著;腐植酸与外源磷的合理搭配施用，使土壤有效磷含量大于单施外源磷和单施腐植酸的方式;在腐植酸与外源磷施用过程中，先施外源磷再施腐植酸，土壤有效磷含量增加速度最快、土壤有效磷含量最高，差异达到显著水平
英文摘要	The effect of outer-source phosphorus usage and the application ways of humic acid on the content of available phosphorus in gray desert soil were studied in a laboratory．The results show that the content of soil available phosphorus was increased at first and then decreased with the increase of outer-source phosphorus usage，and the soil phosphorus fixation rate was increased at first，and then decreased，but increased again with the increase of outer-source phosphorus usage．There was a maximum balance point of available phosphorus in soil．The effect of application ways of outer-source phosphorus and humic acid on soil available phosphorus content was significant． Soil available phosphorus content could be significantly increased by applying humic acid or outer-source phosphorus．The effect of rational application of combining humic acid and outer-source phosphorus on soil available phosphorus content was more significant than that by applying outer-source phosphorus or humic acid only．Soil available phosphorus content could be increased most effectively by applying outer-source phosphorus at first and then humic acid．
