Mulberry shoots were planted in the plain sandland and hill terrace in the eastern of Hebei province

and they were mainly intercropped by peanut and maize.Root distribution of mulberry shoots and its influence on soil moisture and nutrient in Qian'an were studied.The results showed that: the weight of the roots in the 20~ 40 cm soil layer were 60%~ 80% of the total amounts

and distributed decreasingly with the depth increasing.The hairy roots(diameter<3 mm)were 30%~40% of the total amounts

concentrating in the 20~ 40 cm soil layer.The roots(diameter>7 mm) were the least and only 15% of the total amounts.The horizontal distribution mainly concentrated in the cluster of 0~ 100 cm from the center of mulberry shoots cluster in the plain sandland.The weight of roots in the 100 cm soil layer from the cluster was 6.25% of the total amounts.The root vertical distribution could reach up to 3.28 m in depth

and some roots embed the deep soil layer where the horizontal distribution range was little

but the horizontal distribution was obvious in the hill terrace.The roots horizontal distribution could reach to 250 cm in width with few roots embed the rock.The roots weight

diameter and section area distribute characteristics of mulberry shoots were different according to site condition and the depth of the soil.The deepsoil moisture could be increased.There were not obvious moisture deficits in the horizontal range near the cluster.The soil nutrient near the cluster could be improved by the mulberry shoot
