Embodiment 1

[0019] A method for injuring stems to promote the yellowing of black burst tobacco leaves, comprising the following steps,

[0020] The first step is to observe and determine the tobacco plants with black burst tobacco leaves. In the tobacco field, judge the harvest time according to the yellowing of the tobacco leaves by 5-60%. Before the scheduled harvest time is 9 days in advance, according to the natural yellowing of the tobacco leaves , to determine the tobacco strains with black burst tobacco leaves;

[0021] The second step, the treatment of the tobacco plants, classifies the tobacco leaves of the tobacco plants with black burst tobacco leaves determined in the first step, and determines the defertilization and yellowing tobacco plants in the tobacco plants of the false ripening and yellowing. The moisture content of the tobacco leaves is Excessive, excessive accumulation of dry matter, 7-9 days in advance of the scheduled harvesting time, using an antibacterial knife, ...

Embodiment 2

[0023] A method for injuring stems to promote the yellowing of black burst tobacco leaves, comprising the following steps,

[0024] The first step is to observe and determine the tobacco plants with black burst tobacco leaves. In the tobacco field, judge the harvest time according to the yellowing of the tobacco leaves by 5-60%. Before the scheduled harvest time is 9 days in advance, according to the natural yellowing of the tobacco leaves , to determine the tobacco strains with black burst tobacco leaves;

[0025] The second step, the treatment of the tobacco plants, classifies the tobacco leaves of the tobacco plants with black burst tobacco leaves determined in the first step, and determines the defertilization and yellowing tobacco plants in the tobacco plants of the false ripening and yellowing. The moisture content of the tobacco leaves is Excessive, excessive accumulation of dry matter, 5-7 days in advance of the scheduled harvesting time, using an antibacterial knife, ...

Embodiment 3

[0027] A method for injuring stems to promote the yellowing of black burst tobacco leaves, comprising the following steps,

[0028] The first step is to observe and determine the tobacco plants with black burst tobacco leaves. In the tobacco field, judge the harvest time according to the yellowing of the tobacco leaves by 5-60%. Before the scheduled harvest time is 9 days in advance, according to the natural yellowing of the tobacco leaves , to determine the tobacco strains with black burst tobacco leaves;

[0029] The second step, the treatment of the tobacco plants, classifies the tobacco leaves of the tobacco plants with black burst tobacco leaves determined in the first step, and determines the drought and water-deficient Luohuang tobacco plants in the pseudo-ripened tobacco plants. Falling yellow tobacco plants, the tobacco leaf tissue is loose, the moisture content is low, and the dry matter accumulation is less. The whole tobacco leaves fall yellow together, and the yel...

Abstract

The invention relates to the technical field of tobacco leaf yellowing, in particular to a method for promoting yellowing of tobacco leaves free of natural yellow removal through stalk damage. In a yellowing process of the tobacco leaves free of natural yellow removal, tobacco plants are cut annularly to cut off part of nutrient supply channels. Therefore, nutrient supply abilities of overground parts of the tobacco plants are weakened, the leaves are forced to lack nutrients to inhibit transfer of photosynthetic products to roots, the activity of root systems is reduced, and leaf yellowing isfurther promoted.

Description

technical field [0001] The invention relates to the technical field of yellowing of tobacco leaves, in particular to a method for injuring stems to promote yellowing of black burst tobacco leaves. Background technique [0002] Heibaoyan, also known as Hanyan and Paoyan, refers to the general term for a type of tobacco leaves that do not turn yellow naturally when the leaves reach the picking and roasting stage. In actual production, due to uneven soil fertility, excessive fertilization, and early drought, etc., it will happen. Most of the black burst tobacco leaves are caused by the excessive application of nitrogen fertilizer by tobacco farmers in pursuit of high yield. The nutritional imbalance of tobacco plants and poor field management make it difficult for tobacco leaves to fall yellow. Contents of the invention [0003] In view of the technical problems existing in the prior art, the present invention provides a method for injuring the stems to promote the yellowing ...
