Abstract:

In order to clarify the nutrient abundance and deficiency of soil in the main tobacco areas of Meizhou, Guangdong, 83 soil samples were collected from 6 major tobacco producing counties in Meizhou to investigate the nutrient abundance and deficiency of tobacco soil, in order to provide theoretical basis and technical support for soil improvement and reasonable fertilization in tobacco areas. The results showed that the soil was acidic as a whole. The soil organic matter content was abundant, and the proportions of suitable, high and higher were 8.4%, 32.5% and 59.1%, respectively. The soil total nitrogen content was generally high, and the proportions of suitable, high and higher were 4.8%, 24.1% and 71.1%, respectively. The high and higher proportion of soil available phosphorus content were 2.4% and 97.6%, respectively. The low,suitable, high and higher proportion of soil available potassium content were 13.3%, 24.1%, 25.3%, and 37.3%, respectively. Therefore, the amount of fertilizer should be reduced in the actual production, and the soil conditioner should be used rationally to improve the acidity and alkalinity.

Key words: Meizhou tobacco area, tobacco soil, soil nutrient
