前言合理耕作制度是保证不断提高地力及产量的一项综合性农业技术措施,是在一定历史条件下,生产任务与自然条件、生产条件等生产诸因素对立统一的一个平衡体系。它是不断发展的,又是相对稳定的。在“农业学大寨”运动的推动下,广大贫下中农,积极改变生产条件,因地制宜地改革耕作制度,促进了农业生产的迅速发展,积累了丰富的改制经验。省委提 INTRODUCTION The reasonable farming system is a comprehensive agricultural technical measure to ensure continuous improvement of soil fertility and yield. It is a balanced system of opposites under the historical conditions of production tasks, natural conditions and production conditions. It is evolving and relatively stable. Driven by the “Agriculture Studies in Dazhai” movement, the vast majority of poor and middle-income peasants have actively changed their production conditions and reformulated the farming system in line with local conditions, promoted the rapid development of agricultural production and accumulated rich experience in restructuring.
