地膜小麦是近几年推广的一项增产效果十分显著的新技术,但栽培中若管理不当,生育后期易发生早衰现象,影响其增产效果。所谓地膜小麦生育后期,是指小麦从抽穗、开花、灌浆到成熟这一阶段,也是地膜小麦的经济产量形成期。这一阶段的时间虽然不长,但在产量形成中却起着重要作用。 Mulch is a new technology that has been widely applied in recent years. However, if it is improperly managed in cultivation, premature premature aging is likely to occur in later growth period, which will affect its yield-increasing effect. The so-called plastic film wheat later, refers to the wheat from the heading, flowering, filling to mature this stage, but also the economic yield of wheat film formation period. Although this period of time is not long, it plays an important role in the formation of output.
