摘要
在黄土高原北部,采用起垄覆膜(垄上覆膜种植马铃薯,垄沟种植谷子)的垄沟间作田间集雨补灌栽培并结合增施氮、磷、钾化肥,具有显著的增产、增收效果。该技术可大大提高化肥的增产效果和肥料利用率,有明显的集雨增墒效果,同时采用起垄覆膜种植马铃薯与垄沟种植谷子能够合理利用有限的工程集雨,有利于充分利用有限的降水资源,进行节约化农业经营。
A new technic has been studied in north of loess altiplano： Plant potato on the ridge covered by film and millet in the furrow, collect rain water in field and fertilize balanced. The results showed that it can increase the yield remarkable and improve the effect of fertilizer and its coefficient of utilization. Meanwhile, planting in the furrow and covering on the ridge can increase the water content by making the best use of engineer collecting rain water. So this technic can take full advantage of the rain sources and improves the agricultural production.
