EXAMPLE
[Objective] This study aimed to investigate the effects of the combined use of cake organic fertilizer and tobacco special fertilizer on the growth and development as well as the quality of tobacco leaves. [Method] Different ratios of cake organic fertilizer and tobacco special fertilizer were applied. Then, the agronomic traits and leaf quality determining factors were measured and analyzed at different growing stages. [Result] Compared with the control, the tobacco plant height was increased by 3.01%-5.84%, while the number of valid leaves was increased by 5.56%20.39% in all the treatments with combined use of fertilizers. The ratio of sugar to nicotine of leaf was closer to 10±1, and the ratio of nitrogen to nicotine of leaf was closer to 1±0.1. In addition, the combined use of 750 kg/hm^sup 2^ tobacco special base fertilizer and 292 kg/hm^sup 2^ cake organic fertilizer had a better effect for improving the agronomic traits and flavor qualities than all the other treatments. [Conclusion] This study will provide reference for developing special full-aroma tobacco leaf product and new tobacco special fertilizers in Hunan.
