据悉，我国小麦地膜覆盖栽培已取得了重大突破，从而改变了过去覆膜越冬、苗期防寒、拔节前揭膜的方法。现在可以用机械进行覆膜穴播或在覆膜的边线条播（精量播种），在小麦整个生育期能起到防寒、增温和保墒的作用。山西、内蒙古、甘肃、宁夏和新疆等省区已试验、示范成功。 It is reported that China has made major breakthroughs in plastic film mulching cultivation, thus changing the past overwintering film, cold-resistant seedlings, before Jiemian expose method. It is now possible to mechanically drill holes in the film or at the edges of the film for sowing (precision sowing), to provide protection against cold, heat and moisture throughout the growing period of wheat. Shanxi, Inner Mongolia, Gansu, Ningxia and Xinjiang provinces have tested and demonstrated success.
