Wherein, in step (3), the double-ridge film mulching means to mulch two adjacent ridges at the same time. In addition, when mulching, the biodegradable weeding mulching plastic film should be close to ridge surface, and cultivator-hiller earths up the film surface of two adjacent ridges at the same time. This method can integrate three steps - film mulching, covering film surface with a small amount of soil for not being blown away by wind, and earthing up together to one, which simplifies S. tuberosum planting process and greatly improves the work efficiency.-1/1A <；A <；A <；A A <；A 7 A A A A' 'A A "¾~ A~A' A~<；' 7 <；A A A A A A A A A A A A -A <；A '¾, A' A 1' ~<；A ¾" <；AA A>；' A A A >；'A >；, ¾ ,A <；A A ¾ ,<；A A A 1 A ¾ <；A <；A Fig.1
