南平烟区烤烟适宜钾肥施用比例研究
Study on Optimal Ratio of Nitrogen to Potassium for Flue-cured Tobacco in Nanping Area
摘要
Abstract
Objective] The aim was to determine the suitable ratio of nitrogen to potassium for Nanping tobacco producing area.[Method] Experiments of different potassium fertilizer rate were conducted on yield and quality of flue-cured tobacco variety K326.[ Result] The results showed that in condition of lack of potassium soil, applying potassium fertilizer could significantly improve the application of potash fertilizer potassium content in tobacco leaves, which would help improve the quality of tobacco leaves.If ratio of nitrogen to potassium increased to 3. 2, yield decreased with high potassium level in the soil.[Conclusion] Considering the output, quality and economic costs, whether the soil was lack of potassium or not, when the potassium fertilizer rate was 2.5 to 2.8, the yield and quality of K326 were best.关键词
