全膜沟种技术是在田间起大小垄,用地膜覆盖全田,在垄沟播种作物的种植技术。该技术突出全膜和沟种两个关键环节,是一项最大限度抑制无效蒸发,充分利用自然降水,增温、保墒的抗旱节水技术。针对干旱灾害频繁发生、干旱程度逐渐加重、干旱范围逐渐扩大的实际,凌源市农业技术推广中心于2008年开始试验、示范、推广玉米全膜沟种技术,该技术将覆盖抑蒸、膜面集雨、垄沟种植有机地融为一体,比常规半膜栽培技术增温、增光、提墒、保墒的
All-film trench technology is the size of the ridge in the field, covering the whole field with plastic film, sown in the furrow planting techniques. The technology highlights the whole film and furrow two key links, is to maximize the inhibition of ineffective evaporation, full use of natural precipitation, warming, moisture conservation drought water-saving technology. In response to the frequent occurrence of drought disasters, the degree of drought gradually increased, the scope of drought gradually expanded, Lingyuan City Agricultural Technology Promotion Center in 2008 began to experiment, demonstration and promotion of maize all membrane technology, the technology will cover evapotranspiration, membrane surface Rainfall, furrow planting organically integrated than the conventional half-film cultivation techniques warming, light, soil moisture, soil moisture
