Sampling was uniformly completed 7 to 10 days before transplanting and fertilization. Soil samples were taken from 0 to 20 cm in the cultivating layer using a 5 point plum blossom type test. The soils were uniform from top to bottom, the numbers were the same, and the soil was mixed by multiple points. The measurement includes: pH, organic matter, total nitrogen, total phosphorus, total potassium, alkali-hydrolyzed nitrogen, available phosphorus, and quick-acting potassium. Soil nutrients were measured using a soil nutrient tester.
The pH range of all soil samples ranged from 4.64 to 8.59, with an average of 6.39±1.19, and was distributed from acidic to alkaline. The organic matter content was moderate, ranging from 5.17 to 68.30 g/kg, with an average of 23.36±11.73 g/kg. The average contents of total nitrogen and alkaline dissolved nitrogen were 1.27±0.52 g/kg and 100.40±43.98 mg/kg, respectively. The overall nitrogen content was high and was not conducive to the production of high quality tobacco leaves. The variation coefficients of total phosphorus and available phosphorus were relatively large, which were 76.64% and 81.80%, respectively, indicating that the distribution of phosphorus content was not balanced among the pilot sites. The total potassium content ranged from 4.30 to 64.80 g/kg with an average of 20.28±11.35 g/kg; the available potassium varied from 19.10 to 330.10 mg/kg, with an average of 106.89±76.11 mg/kg. The overall potassium content was low. The difference between the pilots was also large, with the coefficient of variation reaching 55.98% and 71.21%, respectively. The variation of nicotine content in the lower leaves was relatively large, and the average nicotine content variation in the middle and upper leaves and whole plants was relatively small and relatively uniform.
The range and coefficient of variation of soil nutrient indicators for different pilot sites are large. The most variable is the available phosphorus and total phosphorus. Besides the effects of soil type, soil parent material and topography, the availability of phosphate fertilizer and low utilization rate in the season are also important factors. The balance of the distribution of available potassium and total potassium is also poor, which may be due to differences in soil structure and texture, resulting in different soil potash capacity. The variations of total nitrogen and alkaline dissolved nitrogen were relatively small, but the overall nitrogen content was high, which may be one of the reasons for higher nicotine content in the upper leaves. The pH value of tobacco soil in different experimental sites was relatively uniform, and the variation of nicotine content in the lower leaves was relatively large.
Soil nutrients and combined nicotine content were analyzed by soil nutrient tester. It was found that soil nutrients were significantly related to nicotine content, and the correlations between nicotine content in tobacco leaf and soil nutrient index were significantly different in different parts. Alkaline nitrogen, pH, and organic matter are positive effects, and total phosphorus and available phosphorus are negative effects. Alkaline nitrogen has the greatest effect on nicotine content. Soil pH has a significant positive correlation with nicotine content of tobacco leaves. The effect of pH on soil nutrient availability affects the direct absorption of nutrients by the tobacco plants and thus affects nicotine content.

Soil Nutrient Analyzer Used to Analyze the Relationship between Nicotine Content of Flue-cured Tobacco and Soil Nutrients
In recent years, the quality of tobacco leaves in China has declined, which is mainly reflected in the higher nicotine content of tobacco leaves and the worsening of chemical composition coordination. Therefore, in order to improve the industrial availability of tobacco, it is critical to reduce the harm and improve the quality of tobacco leaves. Soil is one of the ecological factors that affect the growth and development of tobacco. Appropriate soil fertility is an important basis for the production of high-quality flue-cured tobacco. The soil affects the nicotine content of flue-cured tobacco to a large extent. Through a large number of accurate field experiments, the relationship between nicotine content of flue-cured tobacco and soil nutrients was systematically studied. Seeking dominant soil nutrient factors affecting nicotine content of tobacco leaves, revealing the effects of different soil nutrient factors on nicotine, providing scientific basis for nicotine nutrition regulation and reasonable fertilization, optimizing cultivation techniques, balancing tobacco plant nutrition, and producing nicotine Content is suitable for high quality tobacco leaf industry needs. Soil nutrients are generally measured using a soil nutrient tester, which is also a more accurate method.
