由中国土壤学会土壤肥力专业委员会主持的全国第二次土壤肥力学术讨论会,于1986年5月5日至11日在昆明市举行,共有80位代表参加.代表中有我国土壤学界的老前辈,有中青年学术骨干,还有一批年轻的研究生.大会共收到论文70多篇,中心是土壤肥力问题,内容涉及土壤肥力实质、概念、指标、演变、特征、管理和调控;在研究对象方面,着重于红壤、盐碱土、茶园土、菜园土以及胶林土壤的肥力问题及培肥措施等多方面.30多位代表在大会上宣读了论文,分组会议上大家各抒己见,畅所欲言,进行了热烈的研讨,大会还按排了野外考察.陈恩凤教授根据多年的研究结果,提出微团聚体是土壤肥力的基础物质,可能也能够作为评价土壤肥力的综合指标.在土壤有机胶体,土壤有机矿质复合体形成机制,土壤微团聚体,土壤酶以及土体构造等方面的分部研究均已取得了实质性的进展,为今后提出高产土壤有关因子的调控最佳模式奠定了基础.有的代表指出,地球上不可再生资源是会枯竭的,而目前对土壤的营养库重视不够.因此从现在起必须重视培肥土壤的无机途径,以无机换有机,建立宏大的营养库,为将来的有机农业打下基础.
The Second Soil Fertility Symposium was hosted by the Soil Fertility Professional Committee of China Soil Science Society and was held in Kunming from May 5 to May 11, 1986. A total of 80 representatives participated in the conference. , There are academic backbone young and middle-aged, there are a group of young graduate students. The conference received a total of more than 70 papers, the center is the issue of soil fertility, soil fertility involves the substance, concept, indicators, evolution, characteristics, management and regulation; , Focusing on the fertility problems of red soil, saline-alkali soil, tea garden soil, vegetable garden soil and plastic forest soil, measures of fertilizing and so on. More than 30 delegates read the papers at the conference and all of them expressed their opinions and held their speeches freely Warm discussion, the conference also arranged the field investigation.Chen Enfeng based on years of research results, proposed micro-aggregates are the basic material of soil fertility, and may also be used as a comprehensive evaluation of soil fertility indicators in soil organic colloids, soil organic mineral Subdivision studies on complex formation mechanisms, soil microaggregates, soil enzymes, and soil structure have all been substantial , Laying the foundation for the future development of the best model for controlling high-yielding soil-related factors. Some representatives pointed out that the non-renewable resources on the earth will be exhausted, but the present insufficient attention to the soil nutrient pool. Therefore, from now on must pay attention to fertilization The inorganic pathways of the soil, with inorganic for organic, the establishment of a large pool of nutrients, lay the foundation for the future of organic agriculture.
