Abstract:

To improve the yield and quality of tobacco leaves in Wuding County of Chuxiong in Yunnan, and explore the effects of different types of bio-organic fertilizers on the yield and quality of tobacco leaves, a field comparative experiment was conducted to study the effects of humic acid organic fertilizer, functional microbial agent and bio-organic fertilizer on the growth and development of ‘Yunyan 87’ and the yield and quality of tobacco leaves. The results showed that the application of functional microbial agents, bio-organic fertilizer A and bio-organic fertilizer B could promote early and rapid growth of tobacco plants by 2-3 days. Compared with conventional fertilization, applying humic acid organic fertilizer and bio-organic fertilizer A increased the plant height by 3.57% and 12.37%, the leaf area per plant by -7.73% and 5.83%, and the maximum leaf area in the middle by -10.24% and 21.46%, respectively. Applying humic acid organic fertilizer, microbial agents and bio-organic fertilizer A increased the yield by 12.50%, 2.28% and 14.82%, the output value by 0.16%, -4.02% and 30.13%, and the average price by -10.96%, -6.13% and 13.34%, respectively. The application of bio-organic fertilizer can effectively improve the nutrient composition and pH of tobacco planting soil for the early and rapid growth of tobacco plants, promote the root growth of tobacco plants, improve the quality of tobacco leaves, enhance the chemical coordination of tobacco leaves, and increase economic benefits.

Key words: flue-cured tobacco, bio-organic fertilizer, growth, yield, quality
