摘　　要：１５Ｎ在萧山轻咸砂土中，０～３０ｃｍ土层中横向移动可达４５ｃｍ，３０～５０ｃｍ土层中横向移动可达３０ｃｍ；金华黄筋泥土中１５Ｎ的横向移动为１５ｃｍ。３０～５０ｃｍ土层移动可达３０ｃｍ。两种土壤的纵向移动均达８０ｃｍ。证明１５Ｎ在棉田中的纵向移动范围大于横向移动范围。而横向移动范围与土质有关。The horizontal moving range of 15 N was 45cm and 30cm in 0～30cm and 30～50cm soil layer of saline sandy soil in Xiaoshan,respectively.The horizontal moving range of 15 N was 15cm and 30cm in 0～30cm and 30～50cm soil layer of the quaternary red earth in Jinhua,respectively.The vertical moving distance was 80cm for the two soils.These results showed that the moving scope of 15 N in the cotton field was larger in the vertical direction than in the horizontal direction and the horizontal moving range was related to the soil texture.
