摘要
以烤烟K326为试验对象,研究了不同施磷量对烤烟农艺性状、化学成分及产质量的影响。结果表明:磷肥施用量的不同对烤烟生长发育及产质量有不同程度的影响,随着磷肥施用量的增加,烤烟茎围逐渐增加,上部叶面积也有所增加;当磷肥施用量增至147 kg/hm^2时,产量、上等烟比例、产值最高,分别达2424.36 kg/hm^2、74.21%、59149.01元/hm^2,产值与对照(不施磷肥)相比可增加10184.96元/hm^2。因此,玉溪九溪烤烟生产中的最佳施磷量为147 kg/hm^2。
The effects of different phosphorus fertilizer application rates on the agronomic traits, chemical compositions, yield and quality of flue-cured tobacco variety K326 were studied. The results showed that the application rate of phosphorus fertilizer had different effects on the growth, development, yield and quality of flue-cured tobacco. When the application rate of phosphorus fertilizer increased, the stem girth of K326 increased gradually, and the acreage of its upper leaves also increased to a certain extent. As the application rate of phosphorus fertilizer increased to 147 kg/hm^2, K326 obtained the highest yield, first-class tobacco leaf proportion and output value, reaching 2424.36 kg/hm^2, 74.21% and 59149.01 yuan/hm^2, respectively, and the output value increased by 10184.96 yuan/hm^2 as compared with that in the check(not applying phosphorus fertilizer). Therefore, the optimum application rate of phosphorus fertilizer was 147 kg/hm^2 in the production of flue-cured tobacco in Yuxi area.
