玉米垄作覆膜栽培技术是旱作农业的一项突破性的创新技术,该项技术集覆盖抑蒸、膜面集雨、垄沟种植技术为一体,最大限度地保蓄自然降水,使地面蒸发降到最低,实现了集雨、保墒、增产。近年来贵州省平坝县夏季旱情较为严重,为探索玉米抗旱栽培技术措施,特实施玉米垄作覆膜沟灌技术试验,通过试验探索出处理B即“直播+垄作+全田覆膜”栽培模式产量最高,经济效益最好。
Cultivation technology of maize ridge is a breakthrough innovative technology in dry farming. This technology covers the techniques of evapotranspiration, membrane surface rain collection and furrow planting, maximizes the preservation of natural precipitation and makes the ground evaporate To the minimum, to achieve a rain, soil moisture, increase production. In recent years, Pingba County, Guizhou Province, the summer drought is more serious. In order to explore the technical measures for drought-resistant cultivation of maize, special experiments were carried out to test the effect of maize ridge irrigation and furrow irrigation. The highest yield model, the best economic benefits.
