玉米全膜覆盖双垄沟播技术是农业技术推广人员针对干旱地区降雨量少、时空分布不均、春旱、春寒出现频率高的气候特点,按照玉米生产发育规律及特点,在传统地膜覆盖技术基础上,总结摸索出的一项旱作农业栽培技术。全膜双垄沟播技术地面覆盖率达到100%,有效降低了蒸发,通过全膜覆盖双垄面集流,全部降水进
Covering double-ridge maize mulching sowing technology is the extension of agricultural extension technology in arid areas for less rainfall, uneven spatial and temporal distribution, spring drought, spring cold appear high frequency of climate characteristics, according to corn production and development of the law and characteristics of the basis of the traditional plastic film mulching technology On, summed up to explore a dry farming techniques. Full film double ridge furrow sowing technology ground coverage rate reached 100%, effectively reducing the evaporation, through the whole film covered double ridge collection, all precipitation into
