为服务衡南县大面积优质烤烟的生产,对种植烤烟施用不同量氯肥进行了试验。结果表明:施用氯化钾的处理均能改善烟叶外观品质、提高烟叶产量。当KCl和K2SO4的比例为3︰7时,对烟草产量、质量的影响最为有利,产量较对照增加4.8%,产值增加13.8%。 In order to serve the production of large-area high-quality flue-cured tobacco in Hengnan County, different amounts of chlorine fertilizer were applied to the cultivation of flue-cured tobacco. The results showed that the application of potassium chloride could improve the appearance quality of tobacco leaf and increase the yield of tobacco leaf. When the ratio of KCl and K2SO4 is 3︰7, the effect on tobacco yield and quality is the most favorable. The yield is increased by 4.8% and the output value is increased by 13.8%.
