【摘要】 本文在分析陕西黄土高原干旱缺水现状的基础上,提出以秸秆覆盖、深松及膜侧沟播栽培技术为核心,配套的新型农机具为关键的黄土高原旱作农田机械化自然降水高效利用技术体系;介绍了冬小麦与春玉米两种栽培模式的试验方案以及研制的配套机具的主要性能。试验示范结果表明,实施此项自然降水高效利用与保护性耕作相结合的综合机械化技术,具有显著的增产、节水效果。对确保粮食安全、促进农业增产、农民增收、改善生态环境以及农业的可持续发展有重要意义。更多还原

【Abstract】 With the analysis on the water shortage situation in Shanxi Loess Plateau, this paper puts forward a mechanized technology system for highly efficient use of rainfall in dry farmland of Shanxi Loess Plateau which integrates the essential technologies of stalk mulching, deep loosing and furrow drilling along the two sides of film with the development of new pattern and key farm implements. The two cultivating patterns for winter wheat and spring corn and the performance of these farm implements are tested. The test results show that this technology system that combines highly efficient use of rainfall and conservative farming technologies has greatly improved the yield and saved the irrigation water. These technologies have great significance in securing food supply and improving the grain yield, income of farmers, and ecological environment and sustainable development.更多还原
