不同施钾水平对轮作制烤烟产质量的影响

Effect of Different Potassium Fertilizer Levels on Yield and Quality of Flue-cured Tobacco in Rotation System

采用营养钵育秧移栽大田栽培的试验方法,研究了等量氮磷条件下不同施钾水平下对烤烟农艺性状、产量、品质的影响,结果表明:N、P、K比例为1∶1∶2处理烤烟的农艺性状好,单叶重、干物质重最大,产量高,品质好,为最佳施钾水平。

By using the cultivation method of transplanting the seedlings in the nutritional bowl to the field,this paper studied the effect of different potassium fertilizer application levels on the agronomic traits,yield and quality of flue-cured tobacco under the condition of applying the same amount of nitrogen and phosphorus fertilizer.The results showed that the best ratio of N,P and K was 1∶1∶2,because the flue-cured tobacco in this treatment had good agronomic traits,the highest single-leaf weight and dry matter weight,high yield,and good quality.
