Problems solved by technology

Concentrated collection of pollen, manual pollination, pollination of 2000-2400 flowers per person per day, about 40000-45000 flowers per person per day of mechanical spraying, 10 times more efficient than manual pollen spraying, however, mechanical spraying Compared with artificial powdering, the pollen consumption is larger, and the pollen waste is more. The pollen consumption is about 20 times that of manual powdering. The workload of pollen collection is much increased, and the efficiency is greatly reduced.

Embodiment 1

[0040] (1) Parent planting

[0041] Parents planted in this concentrated, divided into two plots of adjacent planting. The ratio of the number of plants planted to the parents is 1:4. According to the growth period of the parents, the sowing and transplanting periods are determined so that the male parent blooms 6 days earlier than the female parent.

[0042] (2) Centrally collect flower buds

[0043] At the early flowering stage of the male parent, select the buds of the male parent whose corolla tip turns red and the corolla has not opened, and collect flower buds with a bud collection device. Adjust the size of the pocket of the bud collector, load the buds to be picked, cut the buds with scissors, and drop them into the bag.

[0044] (3) Use a simple comb-toothed anther stripper to peel off the anthers

[0045] Use the wooden board as the bottom bracket, and nail 17 metal comb teeth vertically in a row on the bottom bracket, the spacing between the comb teeth is 1.0mm,...

[0054] (1) Parent planting

[0055] Parents planted in this concentrated, divided into two plots of adjacent planting. The ratio of the number of plants planted to the parents is 1:4. According to the growth period of the parents, determine the time of sowing and transplanting, so that the male parent blooms 5 days earlier than the female parent.

[0056] (2) Centrally collect flower buds

[0057] At the early flowering stage of the male parent, select the buds of the male parent whose corolla tip turns red and the corolla has not opened, and collect flower buds with a bud collection device. Adjust the size of the pocket of the bud collector, load the buds to be picked, cut the buds with scissors, and drop them into the bag.

[0058] (3) Use a simple comb-toothed anther stripper to peel off the anthers

[0059] Use the wooden board as the bottom bracket, nail 15 metal combs vertically in a row on the bottom bracket, the spacing between the combs is 1.2mm, and the length is...

Embodiment 3

[0068] (1) Parent planting

[0069] Parents planted in this concentrated, divided into two plots of adjacent planting. The ratio of the number of plants planted to the parents is 1:3. According to the growth period of the parents, the sowing and transplanting periods are determined so that the male parent blooms 7 days earlier than the female parent.

[0070] (2) Centrally collect flower buds

[0071] At the early flowering stage of the male parent, select the buds of the male parent whose corolla tip turns red and the corolla has not opened, and collect flower buds with a bud collection device. Adjust the size of the pocket of the bud collector, load the buds to be picked, cut the buds with scissors, and drop them into the bag.

[0072] (3) Use a simple comb-toothed anther stripper to peel off the anthers

[0073] Use the wooden board as the bottom support, nail 20 metal comb teeth vertically in a row on the bottom support, the distance between the comb teeth is 0.8mm, an...

Abstract

The invention provides a method for collecting tobacco anther and pollinating, and belongs to the technical field of crop breeding. The method for collecting the tobacco anther comprises the following steps: stamens of flowers are distributed among comb teeth of an anther auxiliary stripper, the flowers are pulled in the direction opposite to the growth direction of the stamens, and the comb teeth are used for stripping the anther on filaments; the anther auxiliary stripper comprises a bottom support and the comb teeth fixed to the bottom support, and the distance between every two adjacent comb teeth ranges from 0.8 mm to 1.2 mm. According to the method, the male parent anther is collected through the special anther auxiliary stripper, and the pollen is aired and dispersed, so that the pollen collection efficiency can be obviously improved, the output and consistency of the pollen are ensured, and subsequent hybrid seed production and pollination are facilitated.

Description

technical field [0001] The invention belongs to the technical field of crop breeding, in particular to a method for collecting tobacco anthers and pollination. Background technique [0002] Tobacco is a self-pollinating crop, usually self-pollinating at the same time as flowering. In tobacco breeding work, the propagation of hybrid seeds is an important work content. However, the natural hybridization rate of tobacco is very low, so artificial pollination is necessary to obtain hybrid seeds. [0003] There are several ways of artificial pollination, two of which are more commonly used, one is flower-to-flower pollination, and the other is collecting pollen and pointing pollen. For flower-to-flower pollination, the two varieties that pollinate each other have the same flowering period, and the amount of flowers harvested is relatively large; if pollen is pollinated for each other, there is no big problem with the slight difference in flowering period between the two varieti...
