随着农业机械化的迅速发展,农田基本建设采用机械化施工的范围越来越广。我省已在西山二十八县相继建立了大型农机站,机械修梯田已逐步开展。在黄土丘陵沟壑区机修梯田中,为适应水利化和机械化的要求,田面宽度、地埂高度则需相应增加,采用一般人工培埂的方法,往往达不到质量要求,甚至在培埂过程中,边培边塌,造成劳力的浪费。在目前尚无专用筑埂机械情况下,怎样用推土机修筑梯田埂是机械化修筑梯田中
With the rapid development of agricultural mechanization, the scope of mechanized construction of farmland infrastructures is becoming wider and wider. Our province has set up a large-scale farm machinery station in Xishan 28 counties one after another, and the mechanical repair of the terraces has been gradually carried out. In the loess hilly and gully area of machine-made terraced fields, in order to meet the requirements of water conservancy and mechanization, the width of field surface and ground heights need to be increased accordingly. Generally, the methods of artificial cultivation often fail to meet the quality requirements. Even in cultivation, , Pei Pei collapsed, resulting in a waste of labor. In the absence of special construction machinery at present, how to use bulldozers to build terraced fields is mechanized construction of terraced fields
