中文摘要	对阜康地区灰漠土进行的磷吸附和解吸附实验表明，单施化肥，土壤对磷的吸附会随着施加量的增加而增加。NPK配合秸杆、猪粪施用均可以显著降低土壤对磷的吸附。加秸杆的处理在加入磷30mg/l时就达到了吸附平衡。有机无机复合肥对解磷的效果最好。直接施加过多的秸杆会显著降低磷的解吸。
英文摘要	Phosphorus is an essential nutrient element for the growth of crops. The fixation of phosphorus in gray desert soil is seriously affected by the high content of CaCO3, salinization and alkalization. Therefore, the effectiveness of phosphorus is very low although the soil is rich in phosphorus. In this paper, the experiments of adsorption and desorption of phosphorus in gray desert soil fertilized by the different ways are carried out. The results show that the adsorption of phosphorus in the soil increases with the increase of the spreading quantity of chemical fertilizer, and it can be obviously reduced when the NPK compound straw and dung are spread. An adsorption budget can be achieved when the soil is fertilized by straw added by a quantity of phosphorous for 30mug/l. The effect of desorption is best when the soil is fertilized by the organic-inorganic compound fertilizer. The desorption of phosphorus can be obviously reduced if too much straw is spread.
