摘　　要：本研究是在田间试验条件下,探讨培土、盖稻草、覆膜、种植深度等不同模式对马铃薯生长及块茎产量、品质的影响。结果表明:不同种植深度对马铃薯出苗率影响差异显著;不同处理对马铃薯商品薯产量影响差异显著,其中以栽植深度为15cm盖稻草的T4处理商品薯产量最高,其次是栽植深度为10cm覆膜的T6和栽植深度为5cm盖稻草且培土的T1常规处理;不同处理对马铃薯块茎的淀粉含量、干物质含量等品质的影响差异不显著。A field experiment is carried out to evaluate the effects of different cultivation modes , including hilling, rice straw mulch, plastic membrane mulch and planting depth, on the growth, tubers yield and quality of potato under drip fertigation system. The results show that different planting depth affects potato seedling emergence significantly. Under these experiment conditions, there are significant differences on commercial potato production among various treatments, with the T4 being the highest in commercial potato produition, the T6 and T1 being the better too. The content of starch and dry matter had no difference among the seven treatments.
