玉米机械宽窄行交替休闲保护性耕作田间试验

Field Testing of Corn Mechanized Conservation Tillage with Wide-narrow Row Alternative Fallow

玉米机械宽窄行交替休闲保护性耕作打破以往均匀垄常规耕作模式,将原60cm均匀垄距改成40cm窄行苗带和80cm宽行空白带。田间试验证明,宽窄行交替休闲保护性耕作模式种植的玉米产量、根系分布、群体透光率和土壤理化性状等都有所改变和提高。

Corn mechanized conservation tillage with wide-narrow row alternative fallow is different from conventional tillage mode with uniform ridge.Ridge distance is changed from average 60 cm to narrow seed line of 40 cm and wide gap of 80 cm.Field testing proved that new tillage mode had advantages in many respects,such as,corn yield,distribution of root,transmittance of colony,physical and chemical properties of soil.
