临夏州1994年引进了甘肃省农科院粮作所研究的“小麦全生育期地膜覆盖栽培技术”(简称地膜小麦)经1994～1995年的试验、示范、推广,地膜小麦平均667m2产360.3kg,比同等条件露地小麦增产82.1kg,增产29.51%,证明该项技术适应性广,具有明显的增产、节水、节种、省工、早熟、抗逆性 Linxia introduced in 1994 Gansu Academy of Agricultural Sciences Institute of grain research “wheat during the whole growth period mulching cultivation techniques” (referred to as plastic film wheat) by 1994 to 1995 test, demonstration, promotion, wheat film yield average 667m2 360.3kg , Yielding 82.1kg more yield than the same conditions of open field wheat, an increase of 29.51%, proving that the technology adaptability is broad, with obvious yield, water saving, saving, labor, precocity, stress resistance
