Scope

Scope: This document specifies the terms and definitions of carbon addition and weight loss technology for flue-cured tobacco, including seedling production, land preparation, base fertilization, transplanting, and field management. This document is applicable to flue-cured tobacco cultivation in Yunnan. Main technical content: 1. Terms and definitions The following terms and definitions apply to this document. 1.1 Biochar Biochar is a type of charcoal used as a soil amendment to promote plant growth, which can be applied in agricultural purposes and carbon capture and storage. It differs from traditional charcoal used for fuel. 2. Seedling production Flue-cured tobacco seedlings are produced starting from the end of March each year. The seedling production method follows GB/T 23221. 3. Land preparation and transplanting The soil is deeply plowed (at least 40 cm deep) before transplanting. The planting site for flue-cured tobacco is selected according to NY/T 852, with raised ridges (40 cm high and 80 cm wide) and deep pits (30 cm deep) being constructed. 4. Base fertilization 4.1.1 Biochar The biochar application rate is 4050 kg/ha, with 300 g of biochar applied per pit. 4.1.2 Compound fertilizer Use flue-cured tobacco-specific compound fertilizer with an application rate of 607.5 kg/ha, applying 45 g per pit. The fertilizer is applied to the pit, thoroughly mixed with the biochar and compound fertilizer, and then covered with film before transplanting. 5. Transplanting Transplanting takes place in May each year. Vigorous tobacco seedlings are selected for transplanting using a flue-cured tobacco transplanter. The seedling pit is covered with soil, leaving the tobacco sprout exposed, and sufficient water is applied for root establishment. 6. Field management 6.1 Fertilization Apply controlled-release fertilizer at a rate of 10 g per plant during the rooting or growth period. 6.2 Water management Follow the provisions of G
