四川省从20世纪80年代开始开发推广水旱轮作田免耕栽培技术,目前每年实行免耕栽培的水旱轮作田已达50万hm2以上。水、旱轮作田实行免耕栽培是农业生产上的1项重大改进措施,除了可减少成本、降低劳动强度外,更重要的是能增产5%～8%,深受农民欢迎。1免耕栽培增产机制水、旱轮作田
Since the 1980s, Sichuan Province has been developing and popularizing the no-tillage cultivation techniques for hydroponic rotation fields. At present, the fields with no-tillage and transplanting have reached more than 500,000 hm2 annually. The implementation of no-till cultivation by water and dry-field farming is a major improvement measure in agricultural production. In addition to reducing costs and reducing labor intensity, it is even more important to increase yields by 5% to 8%, which is greatly welcomed by peasants. 1 no-tillage cultivation mechanism of production water, dry round to field
