Analysis and Improvement of Tobacco Planting Soil in Qinba Mountain Area(Shiyan) |
| |
| Abstract: | Objective] In order to investigate nutrients in tobacco growing soils in Shiyan,and proposed relative improvement measures.Meth-od] 1448 soil samples were collected and analyzed from 4 tobacco growing county of Shiyan City.Result] The average soil pH value was 6.50, the average contents of organic matter was 19.10 g/kg, available N was 114.10 mg/kg, available P was 30.00 mg/kg, available K was 155.40 mg/kg,available Zn was 0.97 mg/kg,available Cl was 6.50 mg/kg ,available B was 0.17 mg/kg,available S was 26.70 mg/kg,availa-ble Ca was 2725.00 mg/kg ,available Mg was 212.70 mg/kg,available Cu was 1.18 mg/kg,available Mn was 28.38 mg/kg,available Fe was 30.18 mg/kg.Conclusion] The pH value,contents of organic,available N,available Zn,available B and available Mg content were appropriate in tobacco-growing soil of Shiyan.The content of available P,available S,available Ca,available Cu,available Mn and available Fe were higher.The supply of available K was obviously deficient in some tobacco-growing areas.The soil fertility characteristics had greater differences among differ-ent tobacco-growing county. |
