摘　　要：绝大部分马铃薯品种比较试验以黄皮马铃薯品种为主,缺少与彩色马铃薯品种的对比研究,而且在重底肥轻追肥的条件下进行,并不能很好地表现出不同马铃薯品种的生长特性和产量上限。为了解决这些问题,试验在浅埋滴灌模式下,根据马铃薯薯皮的颜色,将6个参试马铃薯品种分为2组,分别以乌兰察布市重点推广黄皮品种‘希森6号’(CK_(Y))和红皮品种‘后旗红’(CK_(R))作为对照,调查不同品种的物候期、块茎性状、农艺性状、产量性状及养分积累与运移。在黄皮品种中,‘希森6号’(CK_(Y))的产量最高,‘M13’次之,但‘M13’的商品薯率最高且块茎性状的综合表现良好。因此,建议‘M13’在四子王旗继续试验示范。而对于红皮品种来说,‘雪川红’和‘川引2号’产量均显著高于‘后旗红’(CK_(R)),‘雪川红’的商品薯率最高,‘川引2号’次之,分别为88.17%和85.74%,其中‘雪川红’的块茎性状综合表现良好。因此,建议‘雪川红’在四子王旗继续试验示范。Most of variety comparison tests are focused on yellow-skinned potato varieties and lack color potato varieties.Moreover,the growth characteristics and yield potential are limited under the conditions of heavy base fertilizer and light additional fertilizer applications.In order to solve above problems,the present study divided six tested potato varieties into two groups based on the color of potato skins and used key popular varieties in Ulanqab City,yellow skinned variety'Xisen 6'(CK_(Y))and red-skinned variety'Houqihong'(CK_(R))as controls to investigate the phenophase,tuber traits,agronomic traits,yield traits,and nutrient accumulation and transport of different potato varieties under the shallow burial drip irrigation mode.The highest yield was recorded in'Xisen 6'(CKY),followed by'M13',but'M13'exhibited the best tuber traits and the highest marketable tuber percentage in yellow-skinned varieties.Therefore,it is suggested that'M13'continue to be tested and demonstrated in Siziwang Banner.For the red-skinned varieties,the yield of both'Xuechuanhong'and'Chuanyin 2'was significantly higher than that of'Houqihong'(CK_(R)).The highest marketable tuber percentage was recorded in'Xuechuanhong',followed by'Chuanyin 2',which were 88.17%and 85.74%,respectively.The good tuber traits were observed in'Xuechuanhong'and thus,it is suggested that'Xuechuanhong'continue to be tested and demonstrated in Siziwang Banner.
