Since the early 2010s, China Tobacco (Hu‑ bei) Industrial Corporation, in collaboration with China Tobacco (Hubei) Commercial Corporation and scientific research institutions like Huazhong Agricultural University, has conducted standard‑ ized production trials for medium‑sized plants in core growing areas such as Enshi and Shiyan in Hubei province. Its technical approach empha‑ sizes "three controls and one enhancement": con‑ trolling nitrogen (reducing nitrogen application), controlling density (rational planting density), controlling water (precision irrigation based on water requirements during growth stages), and en‑ hancing photosynthetic efficiency and dry matter accumulation. Simultaneously, it developed a sup‑ porting "low‑temperature slow curing" process to promote the degradation of aroma precursors like carotenoids, generating more aroma compounds. Data indicates that the proportion of medi‑ um‑sized plant leaves reaching the "abundant" or "present" oil content grade significantly increased compared to conventional leaves. Total sugar and nicotine content were stably controlled within rea‑ sonable ranges, showing marked improvement in chemical component harmony. More importantly, such leaves exhibit an excellent "skeleton support" function in cigarette formulations, effectively en‑ hancing aroma concentration and smoke fineness. China Tobacco (Hubei) Industrial Corporation widely applies them in premium products under the Huanghelou brand, significantly strengthening the products' differentiated competitiveness. The greater value of the medium‑sized plant with high oil content project lies in its systemic re‑ sponse to the structural contradiction in leaf sup‑ ply and demand. By improving quality per plant rather than simply pursuing yield, the medium‑ sized plant model enables more tobacco fields to produce high‑quality raw materials meeting the needs of premium cigarettes. Solving the upper leaf challenge The above two case studies, though following dif‑ ferent technological paths, both align with indus‑ try development needs. They provide key support for Chinese‑style cigarettes to resolve the struc‑ tural supply‑demand contradiction of upper leaves and enhance the industry's core competitiveness. The Chinese‑style cigarette industry has long faced an imbalance where top‑grade and middle leaves are in high demand, while medium‑grade and upper leaves are unwanted. Upper leaves were often downgraded or wasted due to low usability. Through technological innovation, Xuchang Com‑ mercial Branch and China Tobacco (Hubei) have transformed previously underutilized upper leaves into core raw materials for premium cigarettes. This significantly enhances the resource value of upper leaves, substantially increases the supply of
