１９９４～１９９８年度，在镇原试区进行的旱地冬小麦周年覆膜穴播栽培技术研究结果表明：旱地冬小麦周年覆膜穴播栽培技术具有显著的增产效果。这项技术突出的特点是：把解决旱地冬小麦生长期缺水问题的重点放在降雨高峰期，将天然降雨蓄、盖、聚在土壤中，并与冬小麦全生育期地膜覆盖穴播有机的结合起来。同时系统的研究了主效栽培措施。 From 1994 to 1998, the results of the study on the point-seeding cultivation of winter wheat in dryland in the trial area showed that the dry-land winter wheat planting with point-seeding and film-planting had significant yield increase effect. The salient features of this technology are as follows: Focusing on the issue of water shortage in winter wheat growing season in drylands, it rains, captures and accumulates natural rainfall in the soil at the peak rainfall season, and organically combines with the film-mulching airship during the whole growth period of winter wheat . At the same time systematic study of the main effects of cultivation measures.
