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.
