Problems solved by technology

[0003] The phenomenon of early flowering has advantages and disadvantages. In terms of production, early flowering will cause tobacco plants to accelerate the growth and development process and premature flowering without reaching the proper plant height and leaf number of the variety or local cultivation conditions, which will seriously reduce the quality of tobacco plants. output and quality, thereby reducing economic benefits

Embodiment 1

[0022] The present invention needs to use a tobacco three-dimensional hydroponic module (such as figure 1 shown), including hydroponic racks (preferably 3 layers in this embodiment), pipelines, and nutrient solution buckets.

[0023] The hydroponic module includes a hydroponic stand 1, a three-layer planting tank 2 arranged on the hydroponic stand 1, two spliced ​​planting boards 3 arranged on the planting tank 2, and a liquid inlet 5 connected with each layer of the planting tank 2 The nutrient solution barrel connected with the liquid outlet 6, the planting plate 2 is wider than the planting tank 1cm around, and covers the opening of the planting tank, and 12 planting holes are arranged on each planting plate, and the planting tank 2 is equipped with nutrient solution. Tobacco seedlings can be fixed on the planting hole 4 in an existing manner, and the roots of the tobacco seedlings pass through the planting holes 4 to contact with the nutrient solution, and a pump is arran...

Embodiment 2

[0036] The tobacco three-dimensional hydroponics module used is the same as that in Example 1.

[0037] Step (1) to step (4) are the same as in Embodiment 1.

[0038] In step (5), before the budding of the tobacco, the ambient temperature of the entire hydroponic chamber is kept at a low temperature of 19°C. After tobacco budding, the temperature is adjusted to the normal value of tobacco growth, and the daytime temperature is controlled at 28°C and the nighttime temperature is 25°C.

[0039] In step (6), the flowering time is counted during the flowering period of the tobacco, and the average flowering time of the tobacco is 41 days.

Embodiment 3

[0041] The tobacco three-dimensional hydroponics module used is the same as that in Example 1.

[0042] Step (1) to step (4) are the same as in Embodiment 1.

[0043] In step (5), before the budding of the tobacco, the ambient temperature of the entire hydroponic chamber is kept at a low temperature of 19°C. After tobacco budding, the temperature is adjusted to the normal value of tobacco growth, and the daytime temperature is controlled at 28°C and the nighttime temperature is 25°C.

[0044] In step (6), the flowering time is counted during the flowering period of the tobacco, and the average flowering time of the tobacco is 46 days.

[0045]

[0046] Through the comparison of the above table, it can be seen that the method for obtaining short-cycle tobacco by promoting the early flowering of tobacco described in the present invention, that is, planting tobacco through hydroponics, and keeping low temperature before budding can reduce the flowering time of tobacco to 41-...

Abstract

The invention discloses a method for promoting premature flowering of tobaccos by changing external growth conditions of tobaccos. The method comprises the steps of taking out tissue culture seedlingsfrom a culture bottle, cleaning and disinfecting, then transplanting the cleaned and disinfected tissue culture seedlings onto a planting plate; then arranging the planting plate to the surface of aplanting groove, and meanwhile filling the planting groove with sufficient nutrient solution in advance. Through the technical measures of changing the external growth conditions of tobaccos, such aswater culturing tobaccos in water and keeping low temperature before budding stage, premature flowering of the tobaccos can be obviously promoted, the tobacco growth time is shortened, and the demandson gene function identification and tobacco breeding research can be met, so that the method has good application prospect.

Description

technical field [0001] The invention belongs to the technical field of tobacco hydroponics, and in particular relates to a method for promoting early flowering of tobacco by changing external growth conditions of tobacco. Background technique [0002] tobacco( Nicotiana tabacum ) for Solanaceae ( Solanaceae ) Nicotiana ( Nicotiana ) is an important annual or perennial economic crop. The main purpose of planting tobacco is to obtain leaves. The yield and intrinsic quality of tobacco leaves affect its economic value. Tobacco in Southwest China is mainly planted in mountainous areas with high altitude. During the planting process, early flowering is prone to occur due to environmental factors, its own genetic characteristics and field management. [0003] The phenomenon of early flowering has advantages and disadvantages. In terms of production, early flowering will cause tobacco plants to accelerate the growth and development process and premature flowering without reachi...
