Abstract:

In order to explore the potassium fertilizer application technology of new flue-cured tobacco varieties resistant to black shank, Honghuadajinyuan resistant to black shank disease was used as the material, and a field experiment of potassium fertilizer dosage and topdressing period in Dali, Yunnan province was set up to study the effects of different treatments on the chemical composition, yield and quality of tobacco leaves. The results showed that compared with single topdressing, the leaf length of the middle leaf in fractional topdressing increased by 3.2%-5.3%, the leaf width increased by 6.9%-12.0%, and the potassium and potassium-chlorine ratios increased by 8.0%-11.3% and 13.6%-22.9%, respectively. The upper leaf length increased by 3.2%-5.9%, the leaf width increased by 9.6%-10.8%, and the potassium and potassium-chlorine ratios increased by 8.8%- 12.1% and 22.9%-41.3%, respectively. From the perspective of economic characteristics, the yield of topdressed potassium fertilizer increased by 8.1%-14.0%, the output value increased by 12.6%-21.8%, the average price increased by 4.1%-6.9%, and the proportion of medium and upper-grade tobacco increased by 4.4%-7.0%. In summary, the tobacco plant had a good field growth, coordinated chemical composition, and good sensory quality and yield with the treatment of 217.50 kg/ha potassium fertilizer dosage, 50% each on applying the 30th and 45th day after transplanting.

Key words: Black shank-resistant, Honghuadajinyuan, Potassium fertilizer dosage, Topdressing period, Chemical composition, Yield, Quality
