土壤酸碱度及施硫量对烤烟全硫含量及经济效益的影响
Effects of Soil pH and Sulfur Application Dosage on the Total Sulfur Content and Economic Benefit of Flue-cured Tobacco
摘要
Abstract
[Objective] To research the effects of soil pH and sulfur application dosage on the total sulfur content and economic benefit of fluecured tobacco.[ Method] The mutual effects between paddy soils with different pH and sulfur application dosage in Anhui Tobacco Region were discussed.The influence law of pH and sulfur application dosage on the sulfur content in tobacco leaves were researched.[Result] Applying dolomite powder significantly reduced the soil acid in tobacco growing area of southern Anhui Province .During the growing season of flue-cured tobacco, deacidification effect of dolomite powder applied to the soil during winter tillage gradually weakened.In the southern Anhui tobacco area, decreasing pH was beneficial to the absorption of sulfur in flue-cured tobacco.With the increase of sulfur application dosage, the total sulfur content of flue-cured tobacco in the upper, middle and lower flue-cured tobacco showed an increasing trend, and the sulfur contents in different leaf positions from big to small were in the order of the upper leaf sulfur content, middle leaf sulfur content, lower leaf sulfur content.Excessive dosage of sulfur had negative impact on the economic characteristics of flue-cured tobacco.[Conclusion] In Anhui province, adjusting the soil pH and reasonable sulfur application dosage is an important way to control the sulfur content of flue-cured tobacco.关键词
