Embodiment 1

[0017] The test site of the present invention is the organic tobacco leaf production base of the Raw Material Department of China Tobacco Yunnan Industrial Co., Ltd., which is located in Lawu Township, Binchuan County, Dali Prefecture, Yunnan Province.

[0018] Test materials: the variety of flue-cured tobacco is NC297, at the budding stage; the tools used are branch shears (commercially available products).

[0019] Specific measures: topping is carried out from the budding of the tobacco plants in the tobacco field to the opening of the central flowers of the tobacco plants. Generally, topping is carried out in the evening on a sunny day. Calculated within 22 leaves of each tobacco plant), and at the same time, the number of leaves left by each tobacco plant is 22 pieces. After topping, when the axillary buds germinate and grow to 10 centimeters in succession, wipe the branches, and leave 5 centimeters of branches at the base of the tobacco branches. Wipe the branches once e...

Embodiment 2

[0021] Test location: Organic Tobacco Leaf Production Base of Raw Material Department of China Tobacco Yunnan Industrial Company, located in Lawu Township, Binchuan County, Dali Prefecture, Yunnan Province.

[0022] Test materials and methods: The variety of flue-cured tobacco is NC196: the center flower is open, and the topping and wiping are done manually.

[0023] Specific measures: In addition to leaving 21 tobacco leaves per plant during topping, and leaving 2 leaflets under the inflorescence at the same time, after topping, when the axillary buds germinate and grow to 5 cm in succession, wipe the branches and keep 3 cm branches at the base of the tobacco branches , and the rest of the measures are the same as in Embodiment 1, and will not be repeated here. The control is the traditional manual topping and bud stroking, a comparative experiment in the same field. After the topping, the axillary buds grow and the bud stroking starts, and the bud stroking is once every 7 da...

Embodiment 3

[0025] Test location: Organic Tobacco Leaf Production Base of Raw Material Department of China Tobacco Yunnan Industrial Company, located in Lawu Township, Binchuan County, Dali Prefecture, Yunnan Province.

[0026] Test materials and methods: The variety of flue-cured tobacco is Honghua Dajinyuan: the center flower is open, and the topping and branching are directly done manually.

[0027] Specific measures: In addition to leaving 18 tobacco leaves per plant during topping, and leaving 2 leaflets under the inflorescence at the same time, after topping, when the axillary buds germinate and grow to 8 cm in succession, wipe the branches and leave 4 cm fork stems at the same time, the other measures are the same as Embodiment 1 is the same and will not be repeated here. The control is the traditional manual topping and bud stroking, and the comparison experiment in the same field. After the topping, the axillary buds grow and start the bud stroking. The bud stroking is once every...

Abstract

The invention discloses a method for inhibiting a bud through a bud in organic flue-cured tobacco production, which comprises the steps of: topping during flower budding and center flower blooming of tobacco plants in a tobacco field, wherein 18-22 leaves are left for each tobacco plant during topping, and 1-2 leaflets are left below an inflorescence at the same time; and suckering when the axillary bud successively germinates to 5-10cm after topping, wherein 3-5cm of branch is reserved at the root of the tobacco branch. Compared with the traditional manual bud picking method, the method disclosed in the invention achieves the purpose of inhibiting the growth of the axillary bud, the bud picking can be reduced by 2-3 times per tobacco plant during the growth period in the field, the cost for labor is saved by 60-90 yuan per mu, the labor cost is averagely saved by 33-43%, the working efficiency of the organic flue-cured tobacco production is improved, and an effective method is provided for reducing the chemicals investment in the pollution-free, green flue-cured tobacco production or conventional flue-cured tobacco production.

Description

technical field [0001] The invention belongs to the technical field of organic agricultural cultivation and management, and in particular relates to a method for suppressing buds by buds in planting organic tobacco leaves. Background technique [0002] Flue-cured tobacco is one of the important economic crops planted on a large scale in my country. Yunnan Province is the main production area of ​​flue-cured tobacco in China and one of the important pillar industries in Yunnan. [0003] Flue-cured tobacco is a cultivated crop for the purpose of picking leaves, so all cultivation measures are centered on improving the quality of tobacco leaves. The most prominent problem in the production of flue-cured tobacco is the contradiction between yield and quality. Generally speaking, the higher the output, the worse the quality, but it does not mean that the lower the output, the better the quality. Therefore, in the production management of flue-cured tobacco, while stabilizing the...
