| 摘 要： | 2000年对三湖农场全场3804hm^2耕地的262个土壤样品地测试分析。结果表明：耕层土壤平均有机质含量28.8g/kg、碱解氮118.42mg/kg、速效磷7.02mg/kg、速效钾152.10mg/kg；与1981年相比，有机质、碱解氮分别下降了22.2g/kg和33.6mg/kg，年递减率分别为1.11g/kg和1.68mg/kg。根据测试结果，提出了改良培肥措施。

| Abstract: | soil samples from of 3 804 hm 2 farmland on Sanhu Farm in Hubei were tested. The results were as follows:the mean content of organic matter, alkaline hydrolysis nitrogen,available phosphorus and available potassium in tillage layer were 28 8 g/kg,118 42 mg/kg,7 02mg/kg,152 10 mg/kg respectively in 2000.Compared with the mean content in 1981,organic matter and alkaline hydrolysis nitrogen decreased 22 2 g/kg and 33 6 mg/kg with an annual decrease of 1 11 g/kg and 1 68 mg/kg respectively. Some ways improving soil fertility were suggested based on the results. |
