Abstract

Abstract: Combined with the sideline to increase the income of tobacco growers, we explored the effects of different organic fertilizers on growth and quality of flue-cured tobacco, in order to select the best organic fertilizer matching with the local fields. The cow dung, earthworm dung, earthworm stroma produced in local cattle and earthworm breeding industry, and rapeseed cake in tobacco growing area around Shennongjia were studied to analyze the differences of disease, yield and quality on tobacco after applying different organic fertilizers. The results showed that using cow dung and earthworm+ stroma could improve the agronomic characters of tobacco plants, which showed that cow dung was beneficial to the growth of early stage and earthworm+ stroma was beneficial to the growth of long-term, forming a “medium-sized tobacco” which was more in line with industrial demand, and it could reduce the occurrence of disease, improve the economic characteristics of tobacco and improve chemical composition of tobacco leaves. The application of cow dung and earthworm + substrate in the tobacco field could improve the quality of tobacco leaves and we should encourage the application in areas with necessary conditions.

Key words: flue-cured tobacco, cow dung, earthworm, quality, diseases
