Monitoring the chlorine contents in tobacco leaves and tobacco-planting soils of Baise City, Guangxi
摘要
Abstract
[Objective]The soil and tobacco leaf samples were collected from tobacco-planting counties in Baise City, Guangxi to study the chlorine (CI) contents in tobacco-planting soils and tobacco leaves. in order to provide references for guidance of ecologically-balanced fertilization and development of high-quality and special tobacco leaves. [Method ]Technology of Global Position System (GPS) and soil chemical analysis methods were used to analyze the CI content in soils (20 cm depth), collected before the application of base fertilizer and transplantntation. The flue cured tobacco leaves (C3F) were collected from the tobacco-planting counties for determination of CI content Further, the excess and deficiency of CI content in tobacco leaves were also evaluated. [Result]The CI contents in tobacco-planting soils were relatively low with an average of 19.80 mg/ kg. The CI contents of 75% soil samples from all tobacco-planting counties were found in the range of 10-30 mg/kg. The order of CI content in different soil types was as follows: red soil>yellow soil>paddy soil>lime soil. The CI content in tobacco leaves was found to be low with an average of 0.10% and 30% degree of variation ,and that collected from most of the tobacco-planting counties was found to be deficient The Ci content of 90% of tobacco leaf samples collected from Longlin, Tianlin, Xilin and Leye County was deficient. [Conclusion]The results revealed that the soils of Baise City were deficient in C1 content and not suitable for the production of high-quality flue-cured tobacco. In order to improve the tobacco quality and economic benefits, application of chlorine-containing fertilizers must be recommended for tobacco growing areas of Baise City.关键词
