%X The moisture migration regularity and the new irrigation method in the sandy soil of river ancient channel were studied.The results indicate that the soil water evaporation capacity in 7 days with different treatments of irrigating water quota is not significantly different.The trial in 7-(year) pear trees soil indicates that the sufficient irrigation and the(reduction) of the frequency of irrigation can save water and raise the yield.The soil(moisture) can not make a breakthrough of the(pear) tree's major root system scope as the (irrigating) water quota is 1200m~3/hm~2 and the soil moisture does not (suffice) the peer when the irrigating water(quota) is 600m~3/hm~2 and the peer trees are irrigated 6 times in the growing(period) of the trees.The irrigating water quota of 900m~3/hm~2 and the 4 times irrigation in the growing period of the trees is the suitable method.
