Abstract:: Aiming at the problems of low nutrient content in the aeolian sandy soil with loss of water and other issues existing in Ningxia Helan Mountain area,the automatic weep flow micro-irrigation belt was used,at every 667 m2 irrigating 177,211,244,277 m3 were carried out under field experimental condition to investigate the effect of 4 gradient treatments on total phosphorus and rapidly-available phosphorus from 0 to 80 cm layer in aeolian soil.The results showed that the contents of total phosphorus and rapidly-available phosphorus mainly distributed in soil with the depth of the 0-40 cm.With the increase of soil depth,the contents of total phosphorus and rapidly-available phosphorus gradually reduced,and a relatively low level in the deep soil.Irrigation caused the change in the distribution of total phosphorus and rapidly-available phosphorus.Phosphorus element could be leached to deep layer from surface layer.The higher irrigation rate from top soil to depth,the more phosphorus has been leached.The irrigation with 244 m3 could achieve the best results compared with the other treatments.
