Abstract: The plastic film-covered wheat cultivation should take an appropriate supporting techniques．First，this set of the supporting techniques should be laid in areas that are easily subject to low temperature damage．Second，the extension in irrigation regions could play a wmer-saving and water conservational rule，but the suitable date of seeding should be delayed 7～lOd．The plastic film covered wheat has an obvious yield increase．Third，the plastic film-covered wheat cultivation in the semi-arid guilly region must be allocated with water-rassemble irrigation and field water-assemble planting techniques．Fourth，Chemical herbside and fertilizer appliance，as well as machinery work must be paid attention to．Fifth，the plastic film-covered wheat cultivation must be combined with effective control of the “white film pollution”．
