Problems solved by technology

[0004] In order to solve the technical problems in the prior art that the pollination of frangipani is difficult and the seedlings can only be propagated through asexual reproduction methods such as cuttings and layering, the present invention provides a method for promoting the development of frangipani. The airflow is introduced to form a small airflow vortex in the flower tube, which can make the pollen fall off from the stamen and concentrate on the stigma of the pistil, and finally make the anthers crack automatically and release the pollen. The method of the invention is realized by a device for generating and transmitting airflow Yes, the device has simple structure, low cost and wide applicability

Embodiment 1

[0029] Such as figure 1 As shown, the structure diagram of the device for promoting frangipani growth of the present invention includes a capillary 1 , a positioning ring 2 , a limiting protrusion 3 , a gas delivery device 4 and a helical structure 11 .

[0030] In the embodiment of the present invention, the gas delivery device is any commercially available device that can deliver gas into the capillary, such as a small ventilator.

[0031] Further, the gas delivery device may be connected to the capillary through a capillary connector.

[0032] Further, the gas delivery device is provided with a flow valve for controlling the gas flow.

[0033] Further, the positioning ring surrounds the capillary, and the capillary can move relative to the positioning ring.

[0034] Further, the inner wall of the positioning ring has a helical groove adapted to the helical structure at one end of the capillary.

[0035] When the positioning ring is placed at the center of the frangipani ...

Embodiment 2

[0040] When using the device of Example 1 to promote the development of frangipani, the positioning ring is placed in the center of the corolla of frangipani, and then the helical structure of the capillary is screwed into the cylindrical structure of the corolla through the spiral groove on the inner wall of the positioning ring, when the limit of the capillary When the protrusion touches the positioning ring, the capillary stops moving to the cylindrical structure, and at this time reaches the ventilation valve of the gas delivery device, and the ventilation volume is controlled at 1-12L / s.

[0041] The frangipani is treated by the method of the invention, and it is found that the frangipani bears fruit, and the fruiting rate reaches more than 90%.

[0042] The present invention is characterized in that high-speed air is introduced into the slender flower tube (i.e. the tubular structure of the corolla) of Plumeria frangipani through the helical structure of the capillary at ...

Abstract

The invention discloses a method and device for promoting pollination and fructification of plumeria rubra. The method includes that airflow is fed to the plumeria rubra to enable airflow swirls to form in the crown; the device comprises an airflow delivery unit, a capillary tube with one end connected with the airflow delivery unit and the other end is of a helical structure and a positioning ring used for positioning the capillary tube to the crown. The airflow is fed to the tubular structure of the crown of the plumeria rubra, the small airflow swirls are formed in the tubular structure, pollen is precipitated on a pistil stigma in a concentrated manner after falling off from a pistil, a pollen chamber is cracked automatically to complete fertilization, the technical problem that the plumeria rubra cannot be subjected to sexual propagation is solved, the tradition that the plumeria rubra cannot bear fruit is broken through, and the method is simple and low in cost.

Description

technical field [0001] The invention relates to the field of crop cultivation, in particular to a method and a device for promoting pollination results of plumeria frangipani. Background technique [0002] Plumeria rubra (Plumeria rubra) is a plant in the family Apocynaceae. This tree species has a unique tree shape and is quite ornamental. It is a commonly used tree species in southern gardens. Frangipani has elegant flower color and delicate fragrance during flowering period, and its essence can be extracted for advanced chemical and food purposes. The flowers, bark, branches and leaves of frangipani all have medicinal value. However, because of its rare fruit, it mainly uses cuttings, layering and other asexual reproduction methods to breed seedlings. The study found that frangipani cannot effectively transfer pollen to the stigma, which is its main reproductive obstacle. This has a lot to do with the structure of the frangipani flower tube. The tube of the frangipani ...
