Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments. However, it should be understood that the accompanying drawings are provided only for better understanding of the present invention, and they should not be construed as limiting the present invention.

[0026] like figure 1 As shown, the demale pollination device provided in this embodiment includes a pollinator 10 and an isolation tube 20 . Wherein, the pollinator 10 comprises a pollination tube 11 in a y-shaped structure, an ear ball 12 and a powder storage box 13, and the pollination tube 11 comprises a pollination tube 14, an inclined tube 15 and a middle tube 16 which are integrally arranged, and the powder tube 14 The lower end is a beak-shaped powder outlet, and the upper end communicates with the lower end of the inclined pipe 15 . The upper end of the inclined pipe 15 extends obliquely upwards and communicates with the ear-suction ball 12 , t...

Abstract

The invention relates to a castration-free pollination device and a castration-free pollination method. The castration-free pollination device and the castration-free pollination method are characterized in that the device comprises a pollinator and an isolating tube, wherein the pollinator comprises a pollination tube, a rubber pipette bulb and a pollen storage box; the pollination tube adopts a y-shaped structure; the rubber pipette bulb and the pollen storage box are connected with two upper ends of the pollination tube correspondingly; the lower end of the pollination tube is a pollen outlet; and one end of the insolating tube is used for sleeving a stylus of a female flower needing pollination, and the other end of the isolating tube is used for receiving the pollen output by the pollen outlet of the pollination tube. According to the method, the isolating tube is used and castration is not needed, so the work link for castration is omitted, the problems of incomplete manual castration and damage to pistil are avoided, stamen and pistil can be effectively isolated, and the outcrossing seed-setting risk caused by various reasons is reduced. The isolating tube is used for sleeving for only one time, so the pollution problem of female flower pollen is avoided.

Description

technical field [0001] The invention relates to a pollinator and a pollination method, in particular to a male-free pollination device and method suitable for cotton hybrid seed production. Background technique [0002] In the process of hybrid seed production of cotton, improving the efficiency and quality of seed production can reduce the cost of seed production, increase the yield of seed production, and ensure the purity of seed production, and emasculation and pollination are the key steps. Castration is the removal of the female parent's stamens. This operation has high requirements for the implementer: first, complete castration must be ensured. Incomplete emasculation is likely to cause false hybrids, which seriously affects the quality of seed production. Second, the stigma, style and ovary cannot be damaged. Damage to the stigma, style and ovary can easily lead to a decrease in fertilization efficiency, the formation of deformed bolls and attics, and even the los...
