摘  要:
[目的]为江夏区土壤培肥改良和农业生产提供科学依据。[方法]于2008年在江夏区采集土样,分析并比较自1981年以来江夏区土壤pH值、有机质、碱解氮、速效磷、速效钾含量的变化情况。[结果]1981~2008年江夏区农田土壤养分含量及理化特性发生了很大变化。2008年土壤有机质、碱解氮、速效磷、速效钾含量分别为23.41 g/kg、106.40 mg/kg、15.00 mg/kg、117.90mg/kg,分别比1981年增加7.68%、7.58%、102.70%、13.15%。2008年96.70%的土壤为中性土,pH值为6.5~7.5。[结论]土壤肥力变化的主要原因是耕作制度、施肥习惯的改变和大片荒山荒地开发为工业用地等因素所致。

摘  要:
[Objective] The aim was to provide scientific basis for improvement of soil fertility and agricultural production in Jiangxia area,Wuhan city,Hubei province.[Method] The soil samples covered Jiangxia area were collected in 2008.The change situation of the content of organic matter,alkaline hydrolyzable N,available P,available K and pH value in Jiangxia area from 1981 were studied.[Result] In 1981—2008,the nutrient content and physicochemical characters of the soil in Jiangxia area had great change.In 2008,the average contents of organic matter,alkaline hydrolyzable N,available P and available K in soil were 23.41 g/kg,106.40 mg/kg,15.00 mg/kg,and 117.90 mg/kg,increasing by 7.68%,7.58%,102.70%,13.15% than that in 1981 resp.In 2008,96.7% samples were natural soil and the pH value ranging from 6.5 to 7.5.[Conclusion] The reason of soil fertility changes was the changes of farming system and fertilization modes,as well as the industrialization of barren hills and wasteland.
