农业土壤分类是农业现代化的基础,是土壤科学理论的核心。为了因地制宜改土培肥,针对性的解决生产中关键问题,必先搞好农业土壤分类。我国以农立国五千多年,维持地力不衰而至今,以15亿亩耕地养活10亿人口,这是生态农业的功勋。长期生产实践,丰富了“任地、辨土”经验,这是土壤分类研究的主要源泉。农业土壤基层分类,更是来源于农业生产实践,应根据群众经验,着重反映生产特性,在不同地区突出当地特色,反映土壤区域特点,也即突出影响当地生产的主要因素。由于土壤属
Agricultural soil classification is the basis of agricultural modernization and is the core of soil science theory. In order to adapt soil and improve fertility and solve the key problems in production, we must do a good job in agricultural soil classification. In our country, with the establishment of more than 5,000 years of agriculture and maintaining its fertility, up to now, one billion people have been supported by 1.5 billion mu of cultivated land. This is a feat of ecological agriculture. Long-term production practices have enriched the experience of “any place, distinguish soil”, which is the main source of soil classification research. Grassroots classification of agricultural soil is derived from the practice of agricultural production. It should reflect the characteristics of production according to the masses’ experience, highlight the local characteristics in different areas and reflect the characteristics of the soil area, that is, highlight the main factors that affect the local production. Due to soil genus
