Study on suitable harvesting maturity of Honghuadajinyuan in Baoshan Base of HongyunHonghe

In order to understand the influence of different maturity of Honghua Dajinyuan varieties on the quality of tobacco leaves in Baoshan Base of Hongyun Honghe and to determine the suitable maturity of this variety in Baoshan tobacco area.In this study, three field harvest maturity treatments were set up to compare the quality indexes of fresh tobacco and the appearance quality and economic properties of cured tobacco leaves.The results showed that the appropriate harvesting maturity standard of safflower Dajinyuan varieties in the tobacco area of Hongyun Honghe Baoshan Base was as follows:In the lower leaves, about 14 days after topping, the yellow-green area of leaf surface of tobacco leaves was 50% ~ 60%, and the main veins became more than 1/3 white. In the middle leaves, about 34 days after topping, the yellow-green area of leaf surface of tobacco leaves was 70% ~ 80%, and the main veins turned white by more than 2/3. On the upper leaves, about 48-51 days after topping, the yellow-green area of leaf surface of tobacco leaves was more than 80%, and the main veins turned white by more than 3/4.
