Fuente: WIPO "tobacco agriculture" The present disclosure provides a farming method for increasing soil organic matter and moisture contents and improving sweetness, including the following steps: after rice 5 harvesting, conducting field drainage and a straw treatment to allow rapid drying of the soil, f1ring residual straws by a flame spray gun, and spraying a disinfectant to a field, exposing the field to sun, and conducting Fenlong-ridging tillage with a Fenlong-ridging deep-tillage machine; cultivating tobacco seedlings with a seedling fertilizer, and spraying a microbial compound strain solution at a large cross-shaped stage, planting 10 with a high ridging height, applying a slow-release microbial organic fertilizer to a middle of each ridge through a canal, and conducting tobacco leaf harvesting according to maturation durations of upper, middle, and lower tobacco leaves. The present disclosure adopts a self-propelled Fenlong-ridging deep-tillage machine. The selfpropelled Fenlong-ridging deep-tillage machine can play the role of reconstructing a soil 15 structure, activate the circulation of nutrients in deep soil, and expand the water and fertilizer retention capacities of soil, which provides the excellent maturation conditions for flue-cured tobacco leaves and improves the sweetness of flue-cured tobacco.
