摘要
以佛山澳农菜场为例调查了佛山菜地土壤肥力状况。调查结果发现澳农菜地土壤呈酸性,有机质、有效镁含量处于极度缺乏状态;有效磷、有效钙、有效硫、有效铁、有效铜和有效锰处于丰富状态;而有效氮、有效钾、有效硼和有效锌含量分布不均。建议在蔬菜栽培管理中注重有机质和镁的补充,利用石灰调节土壤酸碱度,采用叶面肥补充微量元素不足。
The soil fertility of vegetable fields of AoNong farm in foshan city were surveyed. Results showed that the soil was acid,the content of organic matter and available magnesium were exceeding lack, while the content of available phosphorus, calcium, sulfur,iron, copper and manganese were rich. However, the distribution of available nitrogen, potassium, boron and zinc were not uniformity. Wesuggested that organic fertilizer and manganese fertilizer should be supply, the soil acidity and alkalinity would be regulated with quicklime, and the lacking of available of boron and zinc would be supply with foliar fertilization during vegetable planting.
