为探明沟垄覆膜种植方式及贮藏温度对连作马铃薯品质的影响,以当地主栽品种"新大坪"为试验材料,研究了平畦不覆膜(CK)、平畦覆膜(T1)、全膜垄播(T2)、全膜沟播(T3)、半膜垄播(T4)、半膜沟播(T5)6种种植方式连作下马铃薯在不同贮藏温度下薯块品质特性的变化规律.3年大田连作试验结果表明,T2和T4薯块干物质、淀粉、还原糖、可溶性蛋白、氨基酸和Vc含量均显著高于其他处理;2014年与2013年相比,5℃贮藏条件下各种植方式薯块干物质、淀粉、还原糖、可溶性蛋白、氨基酸、Vc含量均增加,而有机酸含量降低;各处理在1℃贮藏条件下薯块干物质、淀粉、还原糖、可溶性蛋白、氨基酸和Vc含量均高于5℃,而有机酸含量则较低.连作条件下,垄播种植(T2、T4)有利于马铃薯贮藏品质的提高,且以1℃贮藏温度更有利于保持较高薯块品质.%In order to investigate the effect of different ridge-furrow film planting patterns under continuously cropped on tuber quality of local cultivar potato "Xindaping" during storage ,six treatments including harrowed bedding system without film mulching (CK ) ,harrowed bedding system with film mulching (T1 ) ,completely mulched alternating narrow and wide ridges with ridge planting (T2 ) , completely mulched alternating narrow and wide ridges with furrow planting (T3) ,plastic mulched raised bedding system with bedding planting (T4) and plastic mulched raised bedding system with furrow planting (T5 ) ,were conducted .The results from 3 years field continuous cropping experiment indi-cated that the content of dry matter ,starch ,reducing sugar ,soluble protein ,amino acid and Vc of tuber in T2 and T4 treatments were significantly higher than those in others .Content of dry matter ,starch ,reducing sugar ,soluble protein , amino acid and Vc of tuber in 2014 were higher than those in 2013 ,while organic acid content changed inversely under the 5℃ storage condition .Contents of dry matter ,starch ,reducing sugar ,soluble protein ,amino acid and Vc in tuber under 1℃were higher than those under 5℃ storage condition ,except organic acid .Considering storage quality of tuber , T2 and T4 were recommended in the pattern of continuous cropping ,and high qualities for potato could be maintained under 1℃ storage condition .
