Fuente: WIPO "tobacco agriculture" The invention discloses a method for managing and curing flue-cured tobacco to alleviate chilling injury of tobacco based on salicylic acid application. The flue-cured tobacco management method comprises the following steps: 1) prevention of chilling injury of tobacco: according to weather conditions, spraying salicylic acid solution to prevent chilling injury of tobacco plant which has not occurred chilling injury; 2) grade identification and primary spray of chilling injury tobacco: grade identification of chilling injury tobacco plant is carried out, and that disease degree of chilling injury tobacco is divide into three grades; And spraying once according to the grade of chilling injury tobacco; 3) re-identification and secondary spray of chilling injury tobacco grade: firstly, re-identification and secondary spray of chilling injury tobacco grade are carried out on that tobacco plant 10-20 days aft the primary spraying, and the chilling injury tobacco grade is not more than 1 grade, so that the chilling injury tobacco grade is not more than 1 grade. The invention sprays salicylic acid solution with suitable concentration to alleviate the damage degree according to the identification of chilling injury tobacco of different damage grades, and solves the problem of occurrence of field chilling injury tobacco caused by factors such as sudden drop of ambient temperature, too low temperature, too high soil humidity, too low soil temperature and the like in the field.
