摘要
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。
The results of research at Zhenyuan experiment station during 1994￣1998 showed that the perennial mulching cultivation technique of dryland winter wheat with bunching sowing had a remarkable yield increasing effect. Key point of the technique is to solve water shortage during winter wheat growing period by collecting water from peak rainfall in summer fallow season and storing it in the soil bank. Moreover, it was combined with technique of winter wheat film mulching during the whole growing process. At the same time, the main cultivation measure of the technique was also studied in detail.
