试验表明，在降雨不足300mm的特干旱农业区，实施田间起垄挖沟、垄上铺膜、微型集流，提高天然降水利用率，具有贫水富集、水分叠加、抗旱增产的效果。具有特色的膜坑撮种、垄沟平种、垄膜侧种3种种植方式，增产幅度分别达到10％、50％、60％，并且改变了当地多年不种玉米的历史。 The experiment shows that in the special arid agricultural area with rainfall less than 300 mm, field ridge furrows, ridge furrows, microcirculation and microcirculation can be used to increase the utilization rate of natural precipitation, which has the effects of enrichment of water, superposition of water and drought relief and yield increase. There are three kinds of cultivation methods, such as planting of pits, horizontal planting of furrows and lateral planting of ridge film, with the increase rate reaching 10%, 50% and 60% respectively, and changing the history of non-species of corn for many years.
