摘要
本文针对当前耕作制度中存在的一些问题,结合长春市农业的基本特征和现状,提出了一系列改革现行耕作制度的设想。内容包括:调整农业生产的作物布局,实行轮翻制,创造良好的土壤结构,利用根茬粉碎还田,来提高土壤肥力,实行减免中耕,一次性投肥,以提高劳动效率,达到既增产又增收,为现行耕作制度逐步向现代化集约耕作制度发展指出了方向。
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.
