合理安排作物布局和进行轮作复种,因地制宜地建立合理的耕作制度,是当前提高农作物产量,特别是粮食作物产量的中心问题之一。我省农民在作物布局和轮作复种方面,具有丰富的经验,不少地区都有精耕细作的优良习惯。近年来,许多生产单位由于掌握“充分用地,积极养地,养用结合”的原则,合理地安排耕作制度,从而能不断提高土壤肥力和农作物产量,达到大面积均衡增产。因此,为了大办农业、大办粮食,就必须调查总结不同地区积极用地、养地,不断提高农作物产量的经验,并在原有耕作传统的基础上,进一步研究提出确实有效的适合地区情况的轮 Reasonable arrangements for crop layout and rotation cropping, according to local conditions to establish a reasonable farming system is currently one of the central issues to improve crop yields, especially grain crops. Farmers in our province have rich experience in crop layout and crop rotation, and many areas have fine habits of intensive cultivation. In recent years, many production units have rationally arranged their farming systems by grasping the principle of “full use of land, active raising of land and combination of raising and using of fruits” so as to continuously increase soil fertility and crop yield and achieve large-scale and balanced production. Therefore, in order to run agriculture in large scale, it is necessary to investigate and summarize the experiences of actively using land and raising land in different areas so as to continuously raise the crop yield. Based on the original tradition of farming, we must further study and propose the wheel that is valid and suitable for the situation in the region
