- 摘要:
- 对河北省吴桥县5172份土壤样品的土壤pH值、有机质、碱解氮、有效磷和速效钾含量进行了测定和变异分析。结果表明：吴桥县土壤属碱性，根据全国第2次土壤普查养分分级标准，土壤有机质含量83.58%、碱解氮含量63.15%、速效钾含量59.68%的样点属于4级水平；土壤有效磷含量68.93%的样点属于3级水平。在测定的5个土壤肥力因子中，土壤pH值的变异系数最小，其次是有机质、碱解氮和有效磷，变异系数最大的是土壤速效钾。
- Abstract:
- 5172 soil samples collected from Wuqiao County of Hebei Province were used to determine the soil fertility characteristic (pH，organic content，available nitrogen content，available phosphorus content，rapidly available potassium content) and variation factors.The results showed that the Wuqiao soil was alkaline.According to the classification standard of the second national census of soil，soil organic matter content，available nitrogen content，rapidly available potassium content belonged to level4 standard，which accounted for 83.58%，63.15% and 59.68% of the soil samples.Soil available phosphorus content 68.93% of the soil samples belonged to level3 standard.In five fertility factors，the variation coefficient of soil pH was variable weakly，followed by organic matter content，available nitrogen content and available phosphorus content，and the variation coefficient of rapidly available potassium content was the biggest.
