以‘K326’为材料,探讨了烤烟产质量对钙镁磷肥不同施用量的响应。结果表明:随着钙镁磷肥施用量的增加,烤烟主要农艺性状指标趋好,均价提高;而产量和产值、上等烟和中上等烟叶比例均是先增加后减少,其中以施用量375 kg/hm~2最高;烤后烟叶的淀粉、氯、总糖、烟碱含量随施用量的增加而减少,钾含量随施用量的增加而增加。综合考虑,以施用钙镁磷肥375 kg/hm~2处理的效果最佳。 Using ’K326’ as material, the responses of yield and quality of flue-cured tobacco to different application rates of Ca, Mg and P fertilizers were discussed. The results showed that the main agronomic traits of flue-cured tobacco increased with the increase of the dosages of Ca, Mg and P fertilizers, and the average price increased. However, the yield and output value, the proportion of top and middle and upper tobacco leaves increased at first and then decreased, 375 kg / hm ~ 2. The content of starch, chlorine, total sugar and nicotine in the leaves decreased with the increase of application rate, and the content of potassium increased with the increase of application rate. Taken together, the application of calcium magnesium phosphate 375 kg / hm ~ 2 treatment best.
