Experiment Research on the Ridge-till and No-till Corn Planter

Low-temperature is the key factor for baffling development of conservation tillage in high, cold and easily arid areas of northeast. Combining conservation tillage and ridge tillage is a useful method to solve the problems of low-temperature, spring drought and wind erosion. At present, it is difficult to extend the conservation tillage in ridge-till areas. The main reason is lacking no-till planter, which can work on the permanent ridge stably with corn stubble, and must have anti-blocking ability and good planting quality as well. The 2BML-2 ridge-till and no-till planter was been designed on the base of low-bandwidth rotary tillage. After planting, the shape of the ridge can be almost retained; the rate of cutting stubbles is 100%; the ground temperature values of 50mm and 100mm are 0.7℃ and 0.3℃ higher than that of traditional ridge tillage, respectively, but the soil moisture is 3.9%, 1.3% lower; the output increased 21.3% compared with the tradition ridge tillage. So, the 2BML-2 Planter is good enough to fit the requirement of planting.
