【Abstract】 On the basis of the existing problems of the cropping system and the essential agricul- tural feature in Changchun, this treatise puts foward a series of ideas to improve the pre- sent cropping system. These include regulating the distribution of crops in agricultural production, carrying out the system of ploughing the land periodically to create the good soil structure and re- turning the smashed crop stubble to the farmland to raise the fertility of soil as well as less-or non-tillage and full one-time-ferlilizion for achieving the increase of production and income. Doing so may be the way to develop the cropping system from primary situation to modern intensive farming step by step.更多还原
