Abstract

The invention belongs to the technical field of tobacco plantation and specifically discloses a planting method for improving the tobacco leaf quality of flue-cured tobacco variety Cantonese tobacco 98. The method includes the steps of seedling growing, transplanting, fertilizing and irrigation, pest and disease control, topping and suckering and mature tobacco harvesting. Flue-cured tobacco variety Cantonese tobacco 98 seedlings are transplanted to a special-purpose transplanting matrix for the flue-cured tobacco variety Cantonese tobacco 98 for planting in the step of transplanting. The special-purpose transplanting matrix for the flue-cured tobacco variety Cantonese tobacco 98 comprises: 120-130 parts of purple soil, 80-90 parts of sand soil, 60-80 parts of brown soil, 50-70 parts of loess soil, 40-50 parts of sierozem, 20-30 parts of lime, 50-60 parts of river sand, and 30-40 parts of humic acid. The sensory quality and the quality of the Cantonese tobacco 98 tobacco leaves can besubstantially improved, the ratio of total sugar to nicotine of the Cantonese tobacco 98 tobacco leaves can be substantially reduced by the method, and the method is in favor of highlighting the styleand characteristics of the Cantonese tobacco 98 tobacco leaves.

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 Yueyan 98 tobacco leaves. Background technique [0002] Yueyan 98 was obtained by crossing Coker206 as the female parent and K326 as the male parent to obtain F1, which was obtained through selfing, pedigree selection, backcross aggregation, and pedigree selection again. This variety grows neatly in the field, has strong growth potential, good plant type, and wide adaptability; stable genetic traits, good maturity, loose leaf structure, and moderate leaf thickness. However, the sugar content and sugar-alkaline ratio in the existing Yueyan 98 are relatively high (>10), and the style and characteristics of the tobacco leaves are not prominent. The study found that the soil has a significant impact on the style of tobacco leaves. This is because the soil is the place where the tobacco plants absor...
