玉米全覆膜双垄沟播技术创新与应用

Innovation and Application of Techniques of Maize Whole Plastic-film Mulching on Double Ridges and Planting

王爷府镇位于内蒙古赤峰市喀喇沁旗西南部,地处内蒙古高原与华北平原交界处,黄土丘陵地居多,年降水量350～400mm,属于典型的干旱、半干旱区。天然降水是该地区农业生产的主要水源,干旱缺水已成为制约农业生产发展的主要因素。玉米全膜双垄沟播技术能够提高降水利用效率,具有明显的增温、保墒、增产的效果,2011年王爷府镇共计推广应用733.3hm2,平均产量853.0kg/667m2,较常规半覆膜产量680.5kg/667m2,增产173.5kg/667m2,增收244.0元/667m2。目前,王爷府镇主要推广应用的是玉米全覆膜双垄沟播技术。

WangYeFu town is located in country of KaLaQin, city of ChiFeng ,Inner Mongolia southwest, is located in the Inner Mongolia plateau and the junction of the north China plain, loess hilly land in the majority, the annual precipitation 350--400 mm, belongs to the typical drought half arid area. Natural precipitation in the region is the main source of agricultural production, drought, water shortage has become restrict the development of agricultural production area of the main factors. Techniques of maize whole plastic-film mulching on double ridges and planting can improve rainfall use efficiency, significant temperature, moisture, increasing production effect, 2011 WangYeFu town of popularization and application of 11000 mu, an average of 853.0 kg per mu yield, the conventional half coated per mu yield of 680.5 kg, 173.5 kg, mu mu increase income 244.0 yuan. At present, WangYeFu town main application is techniques of maize whole plastic-film mulching on double ridges and planting.
