优化烟草专用基肥对烤烟生长发育及产质量的影响

为进一步提高肥料利用率，改善植烟土壤理化性状，提高烟叶产质量，对现有烟草专用基肥进行优化改进，以云烟87为研究对象，采用田间小区试验方法，研究了不同优化基肥配方对烟叶生长发育及烟叶产质量的影响。结果表明：不同优化基肥配方与现有烟草专用肥相比，烟株有效叶片数可提高1.99%~4.41%，茎围可增大1.34%~6.30%，烤烟产量和产值分别可提高3.93%~15.90%和8.65%~20.19%，均价提升3.70%~5.11%。综合来看，优化基肥配方2号对改善烟株农艺性状、提高烤烟经济效益效果最好。

Optimized special fertilizer effects on the growth, yield and quality of flue-cured tobacco

In order to improve the utilization rate of fertilizer, improve the physical and chemical properties of tobacco-planting soil, and improve the yield and quality of tobacco leaves, the existing special tobacco base fertilizer was optimized and improved. Yunyan 87 was taken as the research object, and the effects of different optimized base fertilizer on the growth and development of tobacco and the yield and quality of tobacco were studied in situ. The results showed that compared with the existing tobacco special fertilizer, the effective leaf number of tobacco increased by 1.99%-4.41%, the stem circumference increased by 1.34%-6.30%, the yield and output value of flue-cured tobacco increased by 3.93%-15.90% and 8.65%-20.19%, respectively, and the average price increased by 3.70%-5.11%. In conclusion, the optimized base fertilizer No. 2 had the best effect on improving the agronomic traits and improving the economic benefits of flue-cured tobacco.
