耕播机械上实下虚,表面细碎的土壤状态利于苜蓿出苗、出苗整齐;利于苜蓿根系生长和水分渗透,良好的基础条件促进苜蓿的茁壮成长。(1)深松机械。苜蓿收割完毕进行深松作业有利于苜蓿根系生长和水分渗透,传统深松机不能保障工作深度一致现都采用带限深装置的深松机,大平原(Great Plains)深松机工作深度45cm, Plowing machinery on the real virtual, fine crushed soil conditions conducive to alfalfa emergence, emergence and tidy; conducive to alfalfa root growth and water penetration, good basic conditions to promote the robust growth of alfalfa. (1) Deep pine machinery. Alfalfa harvesting completed subsoiling operation is conducive to alfalfa root growth and water penetration, the traditional subsoiling machine can not guarantee the depth of work are consistent with the depth of the device with a limited depth of submerged pine machine, the Great Plains (Subsoiler) Subsoiler working depth 45cm,
