Embodiment 1

[0078]A flue-cured tobacco management method based on betaine application to alleviate gray tobacco, including the following steps:

[0079]1) Identification of the gray level of tobacco leaves and one-time spraying: Identify the tobacco plants that produce gray smoke, and divide the disease degree of gray flue-cured tobacco into six levels as follows:

[0080]Grade 0: The whole leaf is disease-free;

[0081]Grade 1: The main veins or branch veins are scattered with gray and black spots, not exceeding 5% of the leaf area;

[0082]Level 2: Gray-black spots account for 5%-15% of the leaf area;

[0083]Level 3: Gray-black spots account for 15%-30% of the leaf area;

[0084]Grade 4: Gray-black spots account for 30%-45% of the leaf area;

[0085]Grade 5: Gray-black spots account for more than 45% of the leaf area;

[0086]Grade 6: Gray-black spots account for more than 45% of the leaf area, and gray-black spots appear on the petiole and spread to the stem;

Abstract

The invention discloses a flue-cured tobacco management and baking method based on betaine application for relieving gray smoke. The flue-cured tobacco management method comprises following steps: 1)Identification of gray grade of tobacco leaf and first spraying: gray smoke grade identification of tobacco plants with gray smoke; the disease degree of gray flue-cured tobacco comprises 6 grades; and spraying according to gray smoke grade; 2) re-identification of gray degree grade and secondary spraying: firstly, the gray smoke grade is identified again for the tobacco plants 10 to 20 days afterthe first spraying, and the second spraying is applied according to the gray smoke grade until the gray smoke level does not exceed 2 levels. The invention effectively alleviates the occurrence of gray smoke in the field by determining the ash grade of the affected tobacco field and the application of betaine. The method of the invention can effectively improve the health degree of tobacco leavesin the field and the grade of tobacco leaves after roasting, and provides theoretical and technical support for controlling gray smoke in the field.

Description

Technical field[0001]The invention belongs to the technical field of tobacco cultivation, and specifically relates to a flue-cured tobacco management and curing method based on the application of betaine to relieve gray smoke.Background technique[0002]In 2017, the planting area of ​​flue-cured tobacco in my country reached 14.822 million mu, accounting for more than 20% of the world's total. The profits and taxes from flue-cured tobacco planting are the main source of finance and tobacco farmers in some provinces in my country. The latest data show that in 2017, the national tobacco tax revenue reached 11.14.51 billion yuan, accounting for about 7% of the national annual profit and tax. Therefore, the quality and quality of flue-cured tobacco planting directly affects the economic income of tobacco farmers and national fiscal revenue. In the actual production and planting of flue-cured tobacco, due to the influence of soil texture, specific ion content, soil pH, soil water content a...
