Abstract:

The paper aims to evaluate the status of soil nutrient abundance in tobacco planting areas in Longlin, and provide reference for tobacco planting and rational fertilization. The Longlin tobacco-growing area was used as the evaluation unit, and the mathematical statistics were adopted to study the nutrient content and nutrient abundance status of the tobacco soil. The results showed that the soil pH value and total nitrogen were relatively good in the tobacco-growing area of Longlin, soil organic matter, available sulfur, available potassium, available phosphorus, exchangeable magnesium were less appropriate, soil active chlorine, available boron, exchangeable calcium had high suitability. The soil nutrient content in the tobacco-growing area was evaluated for abundance and deficiency, and the results indicated that in the process of tobacco planting, scientific fertilization should be carried out, to control nitrogen, phosphorus, chlorine and calcium, increase potassium, sulfur, magnesium and boron, and reduce the large-scale application of alkaline fertilizers, with more application of organic fertilizers, to achieve the goal of organic, high quality, ecological, characteristic and safe production of tobacco leaves.

Key words: Longlin, tobacco, soil nutrient, abundance evaluation, soil fertility evaluation
