Abstract

The invention discloses a flue-cured tobacco management and curing method based on the application of betaine to alleviate chilling injury tobacco. The method includes the following steps: 1) Prevention of chilling injury tobacco: according to weather conditions, spray betaine on tobacco plants that have not yet suffered chilling injury The solution is used to prevent chilling smoke; 2) Grade identification of chilling smoke and one-time spraying: conduct grade identification on the tobacco plants with chilling smoke, and divide the disease degree of chilling smoke into three levels; and spray once according to the level of chilling smoke; 3) Re-appraisal of the level of chilling smoke and secondary spraying: First, re-identify the level of chilling smoke on the tobacco plants 10 to 20 days after the first spraying, and carry out secondary spraying according to the level of chilling smoke, and the level of chilling smoke will not exceed Level 1 is fine. The present invention sprays betaine solution of suitable concentration according to the identification of cold damage smoke of different damage levels to alleviate the damage degree, and solves the problems caused by factors such as sudden drop in ambient air temperature, too low temperature, too high soil humidity, and too low soil temperature. The problem of cold damage smoke.

Description

technical field [0001] The invention belongs to the technical field of tobacco cultivation, and in particular relates to a flue-cured tobacco management and curing method based on the application of betaine to relieve cold damage tobacco. Background technique [0002] China is a big tobacco leaf producing country in the world and provides abundant raw materials for the world's flue-cured tobacco production. So far, the planting area of ​​flue-cured tobacco in my country has reached 14.82 million mu, accounting for more than 20% of the world's total. Flue-cured tobacco is an important source of income for some provinces in my country and has made a huge contribution to my country's tax revenue. According to the latest report, my country's 2017 tobacco tax accounted for about 7% of the national profits and taxes, amounting to as high as 1114.51 billion yuan. [0003] In the actual production and planting of flue-cured tobacco, due to the influence of low temperature, soil moi...
