以河北省太行山丘陵区农田土壤测土配方施肥中的养分测定数据为素材,依据全国第2次土壤普查养分分级标准,对该区耕地等级进行了划分,结果显示,该区农田土壤全氮和速效磷含量属中等偏上水平,有机质和速效钾含量属中等水平。并将养分测定结果与河北省第2次土壤普查数据进行了对比,结果显示,除土壤速效钾降低了16.43%外,其他3种养分含量均有大幅度提高,土壤有机质、全氮、速效磷含量分别提高了41.83%、42.17%和197.16%。
According to the data of nutrient determination of farmland soil testing and fertilizer formula in the hilly area of Taihang Mountain in Hebei Province, the grade of cultivated land in this area was divided according to the second national soil nutrient classification standard. The results showed that soil total nitrogen, Available phosphorus content is moderately upper level, organic matter and available potassium content is a medium level. The results of nutrient determination were compared with the data of the second soil survey in Hebei Province. The results showed that in addition to soil available potassium decreased 16.43%, the other three kinds of nutrients were significantly increased, soil organic matter, total nitrogen, available fast Phosphorus content increased by 41.83%, 42.17% and 197.16% respectively.
