At present, Chinas sugar cane production is relatively developed countries and regions lagging behind cultivation techniques, extensive planting of sugar cane production, poor management, a low conversion rate of fertilization is not scientific, the utilization of fertilizer, pest control is not in place, ability to withstand natural disasters, mechanized production the application of a small proportion of the labor force to pay more, these problems seriously hampered the cane promote the development of modern agriculture. The traditional planting rely on manual or semi-manual mechanical process of plowing, sowing, casing, bare species sown in the field. Today, the use of the thousands of years of sowing methods, faced with a new problem: is not conducive to large-scale mechanized operations, is not conducive to the meticulous management. Therefore, this article as a starting point, focus on sugarcane planting mac
