在地膜覆盖栽培和膜上覆土栽培条件下，进行了不同栽培模式对播种深度土壤温度、马铃薯生育期、产量和主要经济性状影响的试验。结果表明，播种深度和膜上覆土对马铃薯播种深度土壤温度和出苗期等早期生育进程影响较大，但膨大期、成熟期等后期生育进程基本趋向一致。播种深度10cm、膜上覆土3cm，有利于克服后期高温延长生育期和促进种薯膨大，折合单位产量达39183.75kg/hm2，大薯率达63%，经济效益较好。

In the different cultivation conditions of the plastic film covering and earthing on plastic film, the parameters were obtained including the soil temperature of sowing depth, the growth period, yield, and other main economic traits of potato. The results indicated that the early development process such as the soil temperature of sowing depth and seeding period were main influenced by the sowing depth and earthing on plastic film. The study showed that the sowing depth 10cm and soil covering 3cm were benefi-cial to overcome the latter high temperature,to prolong the growth period and promote the potato expand-ing. And in the condition, the best economic benefits were obtained such as the yield 39 183.75kg/hm2 and the big potato rate 63%.
