Abstract

The invention belongs to the technical field of tobacco planting, and particularly relates to a planting method capable of improving quality of tobacco leaves of Yunyan 87 flue-cured tobacco variety. The method comprises the following steps of seedling breeding, transplanting, fertilizer applying and irrigating, preventing and control of diseases and pests, topping and pruning, and mature picking; in the transplanting step, a seedling of the Yunyan 87 flue-cured tobacco variety is transplanted into a special transplanting medium of the Yunyan 87 flue-cured tobacco variety to be planted; the special transplanting medium of the Yunyan 87 flue-cured tobacco variety is prepared from the following components of 110 to 130 parts of purple soil, 65 to 85 parts of loessal soil, 45 to 65 parts of sand-mud soil, 55 to 75 parts of brown soil, 35 to 55 parts of chestnut soil, 50 to 60 parts of ox liver soil, 20 to 30 parts of lime and 40 to 50 parts of humic acid. The planting method has the advantages that the sensory quality and the quality of the tobacco leaves of the Yunyan 87 flue-cured tobacco variety are obviously improved; a sugar-alkaline ratio of the tobacco leaves of Yunyan 87 is obviously reduced, and the style and characteristic of the tobacco leaves of Yunyan 87 is favorably highlighted.

Description

technical field [0001] The invention relates to the technical field of tobacco planting, in particular to a planting method for improving the quality of flue-cured tobacco variety Yunyan 87 tobacco leaves. Background technique [0002] Yunyan 87 was bred by Yunnan Institute of Tobacco Science and China Tobacco Breeding Research (South) Center with Yunyan 2 as the female parent and K326 as the male parent. In December 2000, it was approved by the National Variety Approval Committee.
