大兴安岭沿麓黑土区翻耕农田微立垡覆盖阻风减蚀技术创新与应用OACSTPCD

The foothill of Daxing′anling Mountains is an important production base of agricultural and livestock products in China.For a long time,unreasonable tillage methods such as excessive tillage and single tillage have accelerated the degradation of farmland wind erosion,quality decline,and reduced production capacity.Therefore,reducing soil wind erosion,improving farmland fertility and crop yield are urgent issues that need to be addressed for sustainable agricultural development.In this article,the techniques and application effects of traditional tilling,long-term no-tilling and rational rotation in areas of different ecological types were reviewed,and the content of core techniques of wind resistance and erosion reduction for micro ripper covering were discussed,as well as their effects on soil wind erosion,water retention and crop growth and yield.It was clarified that micro ripper covering is a key technology and approach for wind erosion prevention and control in winter and spring in the black soil region along the foothill of Daxing′anling Mountains,and the application in large areas has been effective,which solves the scientific and technological problems of the gradual degradation of farmland caused by heavy exposed wind erosion and heavy soil and water loss for a long time.It provides significant support for wind erosion prevention and control of plowed farmland along the foothill of Daxing′anling Mountains and its similar ecological types.
