Problems solved by technology

But this kind of method has strict requirements on pollination varieties, and must be consistent with the flowering period of main plant varieties, otherwise pollination cannot be carried out; and after adopting this method of pollination, the seed setting rate of red flesh dragon fruit is still low, and the yield is low

Embodiment 1

[0024] Use a fan-shaped plastic sheet with a radius of 23cm and a chord length of 22cm to roll into a cone, and the interface is glued with self-adhesive; the open end of the bottom of the cone is cut into a bevel, and the angle between the plane where the bevel is located and the horizontal plane is about 45°. As the collection port of the pollen collection pollinator; a small hole is cut out at the top of the cone as the pollination port of the pollen collection pollinator, the aperture is about 3mm, and the pollination port is sealed with a soft plastic nail of the same size as the pollination port; in order to reduce pollen adhesion, The bonding site is located at the upper end of the bevel, 17cm long from the pollination end.

Embodiment 2

[0026] From mid-to-late May, dragon fruit buds appear one after another, and they can be pollinated after blooming in mid-June. After dawn at 6:30 every day, insert the collecting port of the pollen collecting pollinator of embodiment 1 between the petals and the stamen filaments, vibrate the pollen collecting pollinator, and the pollen falls into the pollen collecting pollinator; pull out the pollination port sealing plastic nail, Shake the pollen from the pollination end into the pollen tube mouth of the stigma, vibrate to make the pollen and the pollen tube wall tightly combined; then pollinate the next flower until the collected pollen is used up, dry the pollination port, and insert plastic nails. Follow the steps above for the next round of pollen collection and pollination. Pollination was completed before the petals wilted at 10:30. If some are not pollinated in time, cut the petals and stigmas, shake the pollen into the cut stigma pollen tubes, and cover them with pe...

Embodiment 3

[0028] On May 15, 2013, red-fleshed dragon fruit began to show flower buds. There were 124 flowers in total, and they bloomed one after another from June 7 to 12. Among them, 50 flowers were collected and pollinated according to the conventional method. The method is as follows: use a brush to sweep the pollen onto the plate In the process, pollen was mixed, and the pollen was dipped with a writing brush and pollinated on the tentacles of the stigma; the other 50 flowers were collected pollen and pollinated according to the method in Example 2. On June 22, the bases of 28 flowers pollinated by the conventional method turned yellow, that is, the pollination was unsuccessful, and the success rate was only 44%; and the pollination by the method of Example 2 only had the bases of 13 flowers turned yellow, and the success rate was only 44%. Reached 74%.

[0029] During August 18-22, 1750 flowers bloomed, and artificial pollination was carried out according to the method disclosed i...

Abstract

The invention provides a pollination method of red-pulp hylocereus undatus. The pollination method comprises the following steps: collecting pollen on stamens of the red-pulp hylocereus undatus when the sun comes up; and conveying the obtained pollen into holes of pistil tops to finish pollination. The invention further provides a pollen collection pollination device. The pollen collection pollination device comprises a hollow cavity, wherein a collection hole is formed in one end of the hollow cavity and a pollination hole is formed in the other end of the hollow cavity; and a detachable plug is arranged on the pollination hole. By virtue of the method provided by the invention, the self-flower pollination of the red-pulp hylocereus undatus can be realized, the pollination success rate can be more than 95% and the setting rate can be improved to be not less than 95%. Furthermore, the pollen collection pollination device provided by the invention has a simple structure and is convenient to manufacture and use; and the pollen collection pollination device is used for carrying out pollen collection and artificial pollination, and can be used for finishing the artificial pollination as soon as possible, so that the labor intensity can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of plant planting, and in particular relates to a method for pollination of red-fleshed dragon fruit. Background technique [0002] Dragon fruit is a perennial climbing succulent plant of the cactus family, which is shaped like an olive. According to the color of pericarp and flesh, it can be divided into three categories: red skin with red flesh, red skin with white flesh, and yellow skin with white flesh. Among them, the red-skinned red-fleshed dragon fruit contains a large amount of anthocyanins, which has good health care effects. However, red-fleshed pitaya has self-incompatibility, low pollination success rate, and low seed-setting rate, so it is necessary to use white-fleshed pitaya pollen for artificial pollination. [0003] When planting red-skinned red-fleshed dragon fruit, the prior art generally selects pollination varieties (generally red-skinned white-fleshed dragon fruit) with strong pollina...
