摘　　要：为了明确酸枣嫁接灰枣后其根系分布与酸枣根系分布特征的差异,采用壕沟剖面网格取样法,按照不同根径(<0.5 mm、0.5~2.0 mm、2.1~5.0 mm、5.1~10.0 mm、>10.0 mm)统计并分析了垂直方向0~80 cm、水平方向0~100 cm范围内的根系,探索其根系分布深度、广度以及集中分布区。结果表明:地下10~50 cm深度为灰枣根系集中分布区,水平方向集中分布区为30~80 cm;地下0~60 cm深度为酸枣根系集中分布区,水平方向集中分布区为10~70 cm。In order to find out the differences of root distribution characteristics between acid jujube grafted with grey jujube and acid jujube, the trench profile grid sampling method was used to count and analyze the roots in the range of 0-80 cm in the vertical direction and 0-100 cm in the horizontal direction according to different root diameters(< 0.5 mm,0.5-2.0 mm, 2.1-5.0 mm, 5.1-10.0 mm, >10.0 mm), so as to explore the depth, breadth and concentration distribution area of root. The results showed that the root concentration distribution area of grey jujube was 10-50 cm in the vertical direction and 30-80 cm in the horizontal direction. The root concentration distribution area of acid jujube was 0-60 cm in the vertical direction and 10-70 cm in the horizontal direction.
