摘要
西北旱农地区,干旱少雨、水蚀、风蚀严重。旱地耕作必须针对这些特点,选用相应的耕作方法。长期沿用的传统翻耕法不完全适应旱地情况。随着现代农业的发展,应因地制宜地研究、推广抗旱耕播新技术、覆盖耕作法、沟垅耕作法,并配合种植制度逐步建立科学的轮耕制。
Droughts and less rainfall,water and wind erosion are serious in the rainfed agriculturalarea in Northwestern China.Rainfed land tillages must aim at these characteritics to selectthe corresponding tillage methods.The long-term used traditional plowing method is notcompletely suitable to the rainfed land conditons,with the development of modern agricul-ture,new techniques of drought resistant tillages and sowings including stubble multching,ridge and furrow should be studied and extended in accordance with local conditions.Inmatching with planting system,scientific rotation system will be gradually established.
