经过我国科技人员的多年试验研究,小麦地膜覆盖栽培技术已在甘肃、山西、山东、陕西等省示范推广。各地示范表明,小麦地膜覆盖栽培技术(以下简称地膜小麦),具有增温、蓄水保墒作用,使小麦早分蘖、穗分化期延长、分蘖成穗率高、穗粒数增加,从而达到旱地小麦增产的目的。此项技术,能最大限度地接纳、保贮、聚集、利用降水和光热资源,充分挖掘土地、种子、地膜、肥料等生产资料的潜力,大幅度提高旱地产量和收益。资料表明,地膜小麦增产幅度为30%～110%。
After many years of scientific and technological personnel of our pilot study, wheat mulching cultivation techniques have been in Gansu, Shanxi, Shandong, Shaanxi and other provinces demonstration and promotion. Demonstration around the country shows that the wheat film mulching cultivation technology (hereinafter referred to as mulched wheat), with warming, water and soil moisture, so that early tillering wheat, spike differentiation period, tillering rate of the ear, grain number increased to reach dryland wheat The purpose of increasing production. This technology can maximize the acceptance, storage, aggregation, use of precipitation and solar thermal resources, fully tap the potential of land, seeds, mulch, fertilizer and other means of production, greatly improve the yield and benefits of dry land. Data show that wheat film yield increase of 30% to 110%.
