钾肥水平对烤烟主要经济性状、化学成分及感官评吸质量的影响

摘要

Under the same application rates of nitrogen and phosphorus,5 potassium levels were set to study the yield and quality of flue -cured tobacco.The results indicated that when the application rate of po-tassium was 150 kg/hm2 and the proportion of N to K was 1∶2,the economic characters and sensory smoking quality both were the best,and the chemical components were the most compatible,which was beneficial to ensure the optimum yield and high quality and reduce the cost of flue -cured tobacco production.%在氮、磷肥用量相同的条件下，本试验设5个钾肥施用水平，对烤烟的烟叶产量和质量进行研究。结果表明，在钾肥（K2 O）用量为150 kg／hm2且氮钾比例为1∶2时，烤烟的经济性状最好，化学成分最为协调，感官评吸质量最高。该施钾量有利于保障烤烟生产的适产和优质，降低生产成本。
