摘要
作者系统地研究了我国多种类型母土上发育的菜园土壤的发生发育特征以及与起源土壤的关系，探讨了菜园土壤的养分富集、肥力演变和污染退化特点。研究表明，菜园土壤随着植菜历史的延长，有机质及各养分元素的含量有明显增加的趋势，其中以速效磷强烈富集和有机质大量积累为最典型的特征。土壤中Ｚｎ、Ｃｕ、Ｐｂ的全量含量和有效态含量均有明显增高的趋势。根据我国菜园土壤资源特点和目前的具体情况提出了管理和持续利用中应注意的问题。
The genetic and developmental characteristics of vegetable cultivated soils derived fromseveral types of Parent soils and the relationship between vegetable cultivated soils and parent soilswere studied. The nutrient enrichment, fertility evolution and pollution degradation characteristics ofvegetable cultivated soils were the investigated. Results showed that as the soil ripening degree increased, there was an evident increasing tendency of increase in the content of organic matter andmany nutrient elements. The typical characteristics of these vegetable cultivated soils were magnanimous accumulation of organic matter and intensive enrichment of available phosphorus. There was also an evident increasing tendency of increase in the total and available content of Zn, Pb, Cu andother metal elements. According to the current situation of vegetable cultivated soil resoures in China, some practices for soil management and sustainable utilization were suggested.
