【摘要】 旱地冬小麦采用地膜穴播栽培,有利于冬前形成壮苗,从出苗至抽穗各生育期明显提前,延长了穗分化时间,使小麦穗粒数比CK增加2.1个。灌浆期光合速率显著高于其他处理,其千粒重比CK增加0.4g,与CK相比增产24.8%,达极显著水平,有效地提高了小麦的增产潜力。

【Abstract】 The experiment results show that, under the film dropping on hill, arid winter wheat is able to form good seeding before winter, each growth period from emergence to heading came before the proper time and ear differentiation became longer,which made the number of grains per ear increase by 2. 1 compared with control. During the grains filling period, the photosynthetic rate was significantly higher than that of other treatments, the 1000-grain weight increased by 0. 4g and yield increased by 24. 8 percent. This is significantly different from control. Therefore,the potential of increasing wheat yield is effectively raised.
