摘　　要：以当地主栽马铃薯品种＂新大坪＂为试验材料,研究平畦不覆膜（CK）、平畦覆膜（T1）、全膜双垄垄播（T2）、全膜双垄沟播（T3）、半膜沟垄垄播（T4）、半膜沟垄沟播（T5）6种栽培模式连作种植,对马铃薯产量及土壤理化性质的影响。结果表明,与CK相比,处理T2、T3、T4和T5显著提高连作马铃薯根区地温;在连作马铃薯全生育期内,各处理土壤电导率总体呈下降趋势,pH呈上升趋势;与CK相比,沟垄覆膜处理土壤电导率提高,pH降低,但差异不显著;除T5外,其他沟垄覆膜处理均能提高连作马铃薯出苗率,T4最高且与CK间差异达到显著水平;沟垄覆膜处理明显提高连作马铃薯产量,增产幅度为1.5%~29.8%,其中T2处理产量最高且与CK间差异显著。In order to study the effects of different film mulching and ridge-furrow planting in continuous cultivation on soil physical and chemical properties and yield of potato,a local dominant variety＂XDP＂was planted under six kinds of cultivation patterns,including flat plot without mulch（CK）,alternating mulched with plastic film and bare plots with no ridges（T1）,completely mulched alternating narrow and wide ridges with ridge planting（T2）,completely mulched alternating narrow and wide ridges with furrow planting（T3）,alternating mulched ridges and bare plots with no ridges and with ridge planting（T4）and alternating mulched ridges and bare plots with no ridges and with furrow planting（T5）.The results indicated that the soil temperature of T2,T3,T4 and T5in root zone of potato were promoted compared with CK in continuous cultivation.During the whole growth period of potato,the soil conductivity of all treatments had an upward trend;however,the soil pH of each treatment had a downtrend.Compared with CK,film mulching and ridge-furrow planting patterns promoted the conductivity of soil and reduced the pH of soil,but the differences among treatments were not significant.Film mulching and ridge-furrow planting could promote the rate of emergence of potato in continuouscultivation with the exception of T5,and T4 was the highest and was significantly different with CK.Film mulching and ridge-furrow planting could promote the yield of potato tuber with 1.5%-29.8%,and the yield of T2 was the highest and was significantly with CK.
