| 摘 要： | 为了掌握土壤肥力状况,采用定位取样测试、ARC/INF软件数据分析等方法,对河北滨海11县区的土壤养分状况分析评价,结果表明:土壤有机质、全氮含量平均为15.86g·kg-1、0.76g·kg-1,除乐亭县外均达缺乏水平;速效钾含量平均76.50mg·kg-1,唐山及沧州滨海区域速效钾含量丰富,平均高于150g·kg-1;沿海11县区有效磷平均含量为20.79mg·kg-1,达到中等水平。从总体养分地域分布看,唐山滨海区高于秦皇岛滨海区,冀东沿海区县高于沧州沿海区县。

| Abstract: | Agricultural land nutrients were analyzed by the methods of locate sampling and ARC soft processing in the coastal areas of Hebei,the results showed that the average contents of organicmatter and total nitrogen were 15.86 g·kg-1,0.76 g·kg-1,all of areas were low level except leting county. The average contents of available potassium was 76.50 mg·kg-1, and it reached 76.50 mg·kg-1 in coastal areas of Tangshan and Cangzhou. The average contents of available phosphorus was 20.79 mg·kg-1, to achieve moderate level. In the overall distribution, soil nutrients in coastal areas of tangshan was highest. |
