摘要:

为使巴东烟区制定烟叶生产农艺措施更具科学性,在不同植烟区域采集了不同海拔和土壤类型的300个土壤混合样品,进行pH、碱解氮、速效磷、速效钾和有机质的常规方法分析。结果表明:巴东县植烟土壤分为3个区域:第1个区域是海拔1200 m以下,该区域的养分特点是pH适中偏酸,碱解氮含量适中,有机质的含量偏高,应该保持“控氮、稳磷、增钾”的施肥措施,并提高烟叶的吸收率和肥料的利用率,同时提高有机质活化程度;第2个区域海拔1200~1400 m,该区域的养分特征是pH适中偏酸,碱解氮、速效磷的含量适中,但是速效钾的含量明显偏低,有机质含量与1200 m以下特征相似。在合理和适当的土壤改良措施下,可以作为优质烤烟的生长区域;第3个区域海拔1400 m以上,该区域的养分差异较大,调整困难,该区域已不适合作为优质烤烟的生产区域。

Abstract:

The relative analysis on pH, alkaline-N, available P, available K and the organic matter of Badong 300 soil mixed samples about different altitude and soil types, in order to develop the level of Badong County Tobacco Corporation’s production technology with more scientific factor, Badong country soil of tobacco was divided into three areas. The first area was altitude below 1200 m, the nutrient characteristics was pH moderate slant acerbity, alkaline-N moderate, the organic matter on the high side, we should take “control nitrogen, maintain stable of phosphorus, increase potassium” of step, at the same time, should improve organic activation degree. The second area was the attitude between 1200-1400 m, the nutrient characteristics were pH moderate slant acerbity, alkaline-N and available P moderate, but available K was obviously lower, the content of organic matter was same to the first area. After took appropriate steps to do soil melioration, this area can be used as quality flue-cured tobacco growing area. The third area was beyond 1400 m, the nutrient content of this area can be vary greatly, hard to adjust it, this area had not suitable for high quality of flue-cured tobacco as a production area.
