为充分利用水分,挖掘旱地小麦生产潜力,我们于1988—1989年在旱地麦田对深、覆盖、沟种综合栽培体系的研究结果表明,这种深层松土,残茬覆盖、沟种集水的方式较传统方式明显简化了作业程序,将水分的蓄、保、用改为一体,30—60厘米土层含水量较传统的耕作方式提高1.3％,小麦产量增加9.5—13.3％。
In order to make full use of water and tap the potential of wheat production in dryland, the results of a comprehensive study on deep, cover and furrow cultivation in dryland wheat fields in 1988-1989 showed that this deep loosening, stubble cover, furrow catchment Compared with the conventional method, the method simplifies the operation procedure obviously. The water storage and preservation are integrated into one. The water content of 30-60 cm soil layer is increased by 1.3% compared with the traditional tillage method and the wheat yield is increased by 9.5-13.3%.
