摘要
以山东费县为例,对3种不同耕地利用方式(粮田、果园、菜地)下的土壤养分状况进行了分析。结果表明:3种不同利用方式耕地土壤有机质含量均偏低;菜地土壤碱解氮、有效磷、速效钾、有效硫、有效锌、有效铁、有效锰和有效硼含量明显高于粮田和果园,有效铜和有效钼含量受耕地管理措施影响较小;粮田土壤pH值最高,菜地土壤pH值最低,蔬菜地土壤具有明显的酸化趋势。
Setting Feixian County of Shandong Province as an example,the soil nutrient conditions under 3 different utilization modes of cultivated land（farmland,orchard and vegetable field） were analyzed. The results indicated that the contents of organic matter in soil from cultivated land of 3 different utilization modes were some lower; the contents of alkaline hydrolytic nitrogen,available phosphorous,rapidly available potassium,available sulfur,zinc,iron,manganese and boron in soil from vegetable field were obviously higher than those in soil from farmland and orchard; the contents of available copper and molybdenum were less influenced by management of cultivated land. The pH value of soil from farmland was the highest and that of soil from vegetable field was the lowest,so the soil from vegetable field had obvious acidification trend.
