It is difficult to extend the conservation tillage in ridge-till areas nowadays, because of lack of no-till planter, which can work on the permanent ridge stably with corn stubble, and have anti-blocking ability and good planting quality. The 2BML-2 ridge-till and no-till planter was been designed on the base of low-bandwidth rotary tillage. Field test of fuel consumption was carried through. The result showed: when the parameters of openers, cover and press disks are invariable, the depth of rotary till is the most important factor, and the width of rotary is the second one, then is the approaching speed; in the range of fitness, with increase of the speed, the quantity of consumption becomes lower; compared to the 2BML-2 planter, the fuel consumption in traditional tillage would increase more than 32%. A fuel consumption model was obtained through the field testing, which can calculate the fuel consumption conveniently according to actual condition and make for selecting appropriate work parameters and designing similar type planter. 
