Problems solved by technology

[0003] There are multiple pistils and ovaries growing on one wheat ear. If only one pistil is pollinated at a time, it will not only waste time and be inefficient, but also easily cause damage to the pistil when the wheat ear repeats multiple pollination operations, which is not conducive to the fertilization and development of the pistil.

[0027] like Figure 1-3 As shown in the figure, a special artificial pollinator for wheat breeding provided by the present invention includes: a powder storage box 101, an air supply mechanism, a pollination head and a pressing rod mechanism. The powder storage box 101 contains wheat pollen, and the powder storage box 101 An air inlet and a powder outlet are provided; the air supply mechanism is communicated with the air inlet of the powder storage box 101, and the air supply mechanism is used for supplying air to the powder storage box 101; the right end of the handle 102 is detachable from the powder storage box 101 The handle 102 is provided with a first through hole 103, and the right end of the first through hole 103 is communicated with the powder outlet; the pollination head includes a sleeve 104, a retaining ring 105, a sleeve 106, an isolation pipe 107 and The pressing cap 108, the sleeve 104 is fixedly connected with the left end of the handle 102, the sleeve 104 is ...

Embodiment 2

[0032] On the basis of Example 1, in order to ensure that the air supply mechanism of the device does not rely on an external air source, it can be used in the field for a long time.

[0033] like figure 1 and 2 As shown, the air supply mechanism includes a handle 201, a connecting rod 202, a gas cylinder and an air storage tank 204, one end of the handle 201 is hinged with the handle 102, and the other end of the handle 201 is hinged with the connecting rod 202, connecting The rod 202 is hinged with the piston 203 of the air cylinder, the air inlet of the air cylinder is communicated with the atmosphere, the air outlet of the air cylinder is communicated with the air inlet of the air storage box 204, and the air outlet of the air storage box 204 is connected with the powder storage box. The air inlet of 101 is communicated.

[0034] The connecting rod 202 is pressed by the handle 201 , and the connecting rod 202 pushes the piston 203 of the air cylinder to supply air to the...

Embodiment 3

[0036] On the basis of Example 2, in order to make the gas in the air storage box 204 have sufficient pressure, so that the high-pressure air can take out more pollen from the powder storage box 101 to ensure the pollination quality.

[0037] like Figure 4As shown, the gas cylinder includes a piston 203, a cylinder 301, a first one-way valve 302 and a second one-way valve 303, the piston 203 is slidably connected to the cylinder 301, and the air inlet and outlet of the gas cylinder are both It is arranged on the side wall of the cylinder body 301, and a second spring 304 is also arranged between the piston 203 and the cylinder body 301. The air outlet is in communication with the atmosphere, the air outlet of the gas cylinder is in communication with the air inlet of the second one-way valve 303 , and the air outlet of the second one-way valve 303 is in communication with the air inlet of the air storage box 204 .

[0038] like Figure 4 As shown, a third one-way valve 401 ...

Abstract

The invention discloses a special artificial pollinator for wheat breeding, which belongs to the technical field of agricultural machinery. The special artificial pollinator for wheat breeding includes: a powder storage box, which is provided with an air inlet and a powder outlet; an air supply mechanism communicated with the air inlet of the powder storage box; a handle, the right end of which is connected to the powder storage box Removable connection; pollination head, including sleeve, retaining ring, sleeve, isolation pipe and pressure cap, the sleeve is fixedly connected with the left end of the handle, the sleeve is provided with a powder inlet, and the powder inlet is connected to the left end of the first through hole Communication, the bottom end opening of the sleeve is fixedly connected with the end face of the retaining ring, the casing pipe wall is provided with a plurality of first powder ports, the isolation pipe wall is provided with a plurality of second powder ports, and the second powder ports can It is communicated with the first powder opening; the lever pressing mechanism is hinged with the handle. The artificial pollinator specially used for wheat breeding of the present invention can not only improve the pollination efficiency by pollinating the whole wheat ear in all directions, but also avoids the risk of damage to the wheat ear during repeated pollination operations, and also ensures the pollination quality.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a special artificial pollinator for wheat breeding. Background technique [0002] Wheat is the main food crop and is widely grown in my country. Good wheat varieties help increase the yield per mu of wheat, so wheat breeding is very important. Wheat is a self-pollinating crop, wind-pollinated, and the outcrossing rate is extremely low under natural conditions. In order to improve the breeding efficiency and achieve favorable gene recombination, for example, in the process of dwarf abortion breeding, pollen sterility is used to carry out a large number of rapid cross-pollination, and then in Selecting superior phenotypes from the fertile plants of the offspring, thereby accelerating the pace of wheat breeding, selective artificial hybridization of wheat is the most commonly used method in wheat breeding. [0003] There are multiple pistils and ovaries growing on a...
