张一扬

Public information about Zhang Yiyang is currently limited, and his research and practice center mainly on tobacco leaf production and tobacco agriculture technology. Judging from the five works held in the collection, his writing focuses on the coordinated development of tobacco leaf raw materials and brands, lean tobacco production technology and its application, tobacco leaf potassium-enhancement technology, tobacco leaf style positioning and base construction, and the development of tobacco leaves from distinctive soils, spanning categories such as industrial technology, finance and economics, and agriculture and forestry. These topics generally arise from the practical needs of tobacco agricultural production and raw material supply, and the content tends toward technical research, method summaries and case analysis—for example, discussing style positioning and base construction using the Wenshan tobacco-growing area as a case. Overall, his works reflect a pragmatic, industry-oriented approach and are suitable for readers in tobacco agriculture, raw material procurement and production management.
