Description

Technical Field

[0001] The present invention relates to the technical field of maize seed production, and specifically to a portable pollination device for maize seed production. Background Art

[0002] Maize seed production is to produce maize seeds with high purity by artificially controlling the pollination process. Such seeds are used for planting in the coming year to ensure the genetic consistency of crops. Maize seed production is of great significance in agricultural production because it directly affects the yield and quality of crops. Since maize is a monoecious crop, in order to ensure the purity of seeds, maize self-pollination is usually adopted for seed production operations, that is, the pollen on the male inflorescence of maize is used to pollinate the female inflorescence of the same maize plant. At the same time, if we want to achieve seed diversity, we can also carry out seed production through hybridization, that is, using the pollen on the male inflorescence of maize to pollinate the female inflorescences of different maize plants.

[0003] Whether it is self-pollination or cross-pollination for seed production, in order to avoid the interference of other factors and ensure that the pollination process is carried out completely according to the preset requirements, that is, for self-pollination, the pollen scattered on the female inflorescence completely comes from the male inflorescence of the same plant, and for cross-pollination, the pollen scattered on the female inflorescence completely comes from the artificially selected male inflorescence. We usually adopt the form of bagging the male and female inflorescences respectively for pollination operations, that is, pre-bagging the male and female inflorescences to isolate them from the outside world. When artificial pollination is carried out, first shake the pollen on the male inflorescence into the bag, then remove the bag containing the pollen, and then remove the bag on the female inflorescence, and at the same time, put the bag containing the pollen on the female inflorescence again.

[0004] However, during the pollination period, the air in the field environment is filled with a lot of other pollen. For the bagging pollination operation, it has certain skill requirements. If the operation is improper, during the bagging pollination process, the external pollen is very easy to mix into the female inflorescence, thereby affecting the result of seed production. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a portable pollination device for maize seed production, which solves the problems of high operation difficulty of the current bagging pollination and easy mixing of other pollen during the pollination process.

[0006] To achieve the above object, the present invention is realized by the following technical solutions: A portable pollination device for corn seed production, including a first bag and a second bag. The bottom of the first bag is provided with a forked first bag mouth and a second bag mouth. The first bag is sleeved on the male ear of corn through the first bag mouth, and at the forked part, a binding band is used to tie and seal the first bag mouth to the corn stalk, so that the male ear is isolated from the outside. A pollen storage device is provided at the second bag mouth for storing the pollen falling from the male ear. The bottom of the second bag is provided with a third bag mouth. The second bag is sleeved on the female ear of corn through the third bag mouth, and a binding band is used to tie and seal the third bag mouth to the corn stalk, so that the female ear is isolated from the outside. The top of the second bag is provided with a fourth bag mouth, and the fourth bag mouth is in a normally closed state. When pollinating, the fourth bag mouth is opened, and the pollen falls into the female ear in the second bag through the pollen storage device.

[0007] Preferably, the pollen storage device includes a first fixing ring. One end of the first fixing ring is fixedly connected to the second bag mouth, and the other end is provided with a detachable pollen storage dish. The pollen storage dish is a cylindrical structure with an open top, and its interior is communicated with the second bag mouth through its open top.

[0009] Preferably, the pollen storage device includes a second fixing ring. One end of the second fixing ring is fixedly connected to the second bag mouth, and the other end is provided with a detachable outer cylinder. The size of the outer cylinder is matched with the caliber of the fourth bag mouth. One end of the outer cylinder located inside the second bag mouth is provided with four through holes one symmetrically distributed around its axis, and the other end is an open structure. An inner cylinder is rotatably connected inside the outer cylinder. One end of the inner cylinder is provided with four through holes two symmetrically distributed around its axis.

[0014] Through the arrangements of the first bag and the second bag, the male and female ears of corn are in a state isolated from the outside world, thus avoiding the influence of external pollen on seed production in daily life. At the same time, through the arrangement of the pollen storage device, in cooperation with the second opening of the first bag and the fourth opening of the second bag, during the pollination process, the pollination operation can be completed only through the pollen storage device, without the need to remove the bag and repeatedly put on the bag, thereby simplifying the pollination process, reducing the operation difficulty, and greatly reducing the probability of external pollen mixing during the bagging and pollination process. Furthermore, the precision of seed production is improved, and the genetic consistency of crops is ensured. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Embodiment 1:

[0030] Please refer to the attached Figure 1 - attached Figure 3 , the embodiment of the present invention provides a portable pollination device for corn seed production, including the first bagging 10 and the second bagging 20. The bottom of the first bagging 10 is provided with a bifurcated first bag mouth 101 and a second bag mouth 102. The first bagging 10 is sleeved on the male spike of the corn through the first bag mouth 101, and the first bag mouth 101 and the corn stalk are tied and sealed at the bifurcation to isolate the male spike from the outside. A powder storage device 30 is arranged at the second bag mouth 102 for storing the pollen falling from the male spike. The bottom of the second bagging 20 is provided with a third bag mouth 201. The second bagging 20 is sleeved on the female spike of the corn through the third bag mouth 201, and the third bag mouth 201 and the corn stalk are tied and sealed to isolate the female spike from the outside. The top of the second bagging 20 is provided with a fourth bag mouth 202, and the fourth bag mouth 202 is in a normally closed state. When pollinating, the fourth bag mouth 202 is opened, and the pollen falls onto the female spike in the second bagging 20 through the powder storage device 30.

[0031] Through the settings of the first bagging 10 and the second bagging 20, the male spike and the female spike of the corn are in a state of being isolated from the outside, thereby avoiding the influence of external pollen on seed production in daily life. At the same time, through the setting of the powder storage device 30, in cooperation with the second bag mouth 102 of the first bagging 10 and the fourth bag mouth 202 of the second bagging 20, during the pollination process, the pollination operation can be completed only through the powder storage device, without taking the bag and repeating the bagging, thereby simplifying the pollination process, reducing the operation difficulty, and greatly reducing the probability of external pollen mixing during the bagging pollination process. Furthermore, the precision of seed production is improved, and the genetic consistency of crops is ensured.

[0032] The powder storage device 30 includes a first fixing ring 301. One end of the first fixing ring 301 is fixedly connected to the second bag mouth 102, and the other end is provided with a detachable powder storage dish 302. The powder storage dish 302 is a tubular structure with an upper opening, and the inside of the powder storage dish 302 is communicated with the second bag mouth 102 through its upper opening.

[0033] The upper opening of the powder storage dish 302 is connected to the second bag mouth 102 through the first fixing ring 301. The first fixing ring 301 is fixedly connected to the second bag mouth 102, and the powder storage dish 302 and the first fixing ring 301 are detachably connected, such as snap connection, threaded connection, etc. It is necessary to ensure that the pollen from the outside will not enter through the connection between the two. When pollinating, shake the tassel, and the pollen on the tassel will fall into the powder storage dish 302 for storage. Then remove the powder storage dish 302, and at the same time open the upper cover of the fourth bag mouth 202 on the ear to be pollinated, pour the pollen in the powder storage dish 302 into the second bag 20, then close the upper cover of the fourth bag mouth 202, and gently shake the second bag 20 to make the pollen scatter evenly. At this time, the pollen will fall into the ear to complete the pollination process.

[0034] Embodiment Two:

[0035] Please refer to the attached Figure 4 - attached Figure 5 When pouring the pollen in the powder storage dish 302 into the second bag 20, there is a problem that the pollen is likely to spill and be wasted. That is, during this process, when the powder storage dish 302 is tilted, the pollen is likely to spill, and it is difficult to ensure that all the pollen falls into the second bag 20. To solve this problem, on the basis of the above embodiment, this embodiment improves the second bag 20, that is:

[0036] A collapsible bellows one 2021 with two open ends is provided on the fourth bag mouth 202. One end of the bellows one 2021 is communicated with the fourth bag mouth 202, and the other end is matched with the upper opening end of the powder storage dish 302, and a detachable sealing cover one 2022 is provided.

[0037] Fix a section of collapsible bellows one 2021 on the fourth bag mouth 202. Since the bellows one 2021 can be stretched and bent, when performing the pollination operation, the bellows one 2021 can be first stretched and bent to make the end with the sealing cover one 2022 face down. Then remove the powder storage dish 302 containing pollen, open the sealing cover one 2022, and at the same time, without tilting the powder storage dish 302, keep it in a vertical state and connect it to the opening of the bellows one 2021 where the cover is opened. The connection method can be snap connection or threaded connection, or even directly insert it into the opening of the bellows one 2021 where the cover is opened, as long as it is ensured that the pollen will not leak. After connection, then turn the bellows one 2021 and the powder storage dish 302 at the same time, so that the pollen in the powder storage dish 302 falls into the bellows one 2021 and finally enters the second bag 20, that is, the pollination operation is completed. Due to the blocking and guiding effect of the bellows one 2021, the problem of pollen spilling from the powder storage dish 302 is avoided.

[0038] Embodiment 3:

[0039] Please refer to the attached Figure 6 - attached Figure 8 , in the above embodiment, since the powder storage dish 302 has an open structure, after it is removed, its interior will come into contact with the external environment. Although the contact time is very short, there is still a possibility of being contaminated. To solve this problem, on the basis of the above embodiment, the structure of the powder storage device 30 is further improved in this embodiment. That is:

[0040] The powder storage device 30 includes a second fixing ring 303. One end of the second fixing ring 303 is fixedly connected to the second bag mouth 102, and the other end is provided with a detachable outer cylinder 304. The size of the outer cylinder 304 matches the caliber of the fourth bag mouth 202. Four through holes 3041 symmetrically distributed around its axis are opened at one end of the outer cylinder 304 located inside the second bag mouth 102, and the other end is an open structure. An inner cylinder 305 is rotatably connected inside the outer cylinder 304. Four through holes 3051 symmetrically distributed around its axis are opened at one end of the inner cylinder 305. The outer wall of the inner cylinder 305 fits against the inner wall of the outer cylinder 304. When the through holes 3041 and 3051 are in a coaxial state, the inner cylinder 305 is rotated 45°, the through holes 3041 and 3051 are staggered from each other, and the through holes 3041 are blocked by the wall of the inner cylinder 305, and the through holes 3051 are blocked by the wall of the outer cylinder 304.

[0041] The outer cylinder 304 is connected to the second bag mouth 102 through the second fixing ring 303. The second fixing ring 303 is fixedly connected to the second bag mouth 102, and the outer cylinder 304 and the second fixing ring 303 are detachably connected, such as snap connection, threaded connection, etc. Four through holes 3041 symmetrically distributed around its axis are opened on the top wall of the outer cylinder 304, and the bottom end is open. An inner cylinder 305 is rotatably connected inside it. The outer top wall of the inner cylinder 305 fits against the inner top wall of the outer cylinder 304, and four through holes 3051 symmetrically distributed around its axis are also opened on the top wall of the inner cylinder 305. The through holes 3041 and 3051 correspond to each other so that the two can be in a coaxial state. At the same time, the inner cylinder 305 is rotated 45°, the through holes 3041 and 3051 are staggered from each other, and the through holes 3041 are blocked by the wall of the inner cylinder 305, and the through holes 3051 are blocked by the wall of the outer cylinder 304 to block the inner cylinder 305 and isolate it from the outside.

[0042] When the pollination operation is performed, the inner cylinder 305 is first rotated to make the through hole 1 3041 and the through hole 2 3051 coaxial, and then the tassel is shaken, and the pollen on the tassel passes through the through hole 1 3041 and the through hole 2 3051 in turn, and falls into the inner cylinder 305 for storage, and then the inner cylinder 305 is rotated 45 degrees to make the through hole 1 3041 and the through hole 2 3051 staggered with each other, and the inner cylinder 305 is blocked. At this time, the outer cylinder 304 is removed, the upper cover of the bag opening 4 202 is opened, and the outer cylinder is 304 is inserted into the bag opening four 202, and the inner cylinder 305 is rotated 45 degrees again to restore the coaxial state of the through hole one 3041 and the through hole two 3051. At this time, the pollen in the inner cylinder 305 can fall out from the channel formed by the through hole two 3051 and the through hole one 3041, and enter the bag two 20 to complete the pollination process. The outer cylinder 304 and the inner cylinder 305 cooperate with each other to make them in a blocked and isolated state after being removed, thereby avoiding the contamination of the pollen in the inner cylinder 305 by external pollen.

[0043] Embodiment 4:

[0044] Please refer to the attached Figure 9 In the above embodiments, the pollination process is carried out by direct dumping. Although this method is fast, it has certain defects. For example, due to direct dumping, the pollen may enter in blocks, resulting in uneven pollination or even pollination failure. Although the pollen can be moved in the bag 20 by shaking the bag 20 to improve the uniformity of pollination, the bag mouth 3 201 of the bag 20 and the corn stalk may be damaged or cracked during the shaking process, making it impossible for the bag 20 to continue to isolate the female ear. At the same time, the shaking process may also affect the female ear, resulting in poor pollination. In order to solve this problem, this embodiment further improves the structure of the powder storage device 30 on the basis of the above embodiments. That is:

[0045] The other end of the inner tube 305 is sleeved with and communicated with a manual air bag 306 .

[0046] A manual air bag 306 is connected to the bottom end of the inner cylinder 305, and the two are interconnected. In this way, on the one hand, when taking pollen, the manual air bag 306 is squeezed to repeatedly suck the pollen at the bag mouth 102, so that the pollen enters the inner cylinder 305 in a discrete state. On the other hand, during pollination, the manual air bag 306 is squeezed to generate an airflow to spray the pollen in the inner cylinder 305 in a discrete state, so that the pollen is evenly distributed in the bag 20, simulating the natural pollination process, thereby solving the problem of uneven pollination. At the same time, there is no need to shake the bag 20 again, avoiding the problem of damage to the bag 20 and the female ear.

[0047] Embodiment five:

[0048] Please refer to the attached Figure 10, on the basis of the above embodiments, this embodiment provides another structure of the powder storage device 30, which achieves the same effect as the structure in Embodiment 4.

[0049] The other end of the inner cylinder 305 is provided with a push rod 307 passing through it. A piston 308 is slidably connected in the inner cylinder 305, and the center of the piston 308 is fixedly connected to the end of the push rod 307.

[0050] By arranging the piston 308 and the push rod 307 in the inner cylinder 305 to form a suction device structure. Similarly, when taking powder, the push rod 307 is pushed and pulled to repeatedly suck the pollen at the second bag mouth 102, so that the pollen enters the inner cylinder 305 in a discrete state. On the other hand, when pollinating, the push rod 307 is pushed and pulled to generate an air flow to eject the pollen in the inner cylinder 305 in a discrete state, so that the pollen is evenly distributed in the second sleeve bag 20.

[0051] Embodiment Six:

[0052] Please refer to the appendix Figure 11 - Appendix Figure 12 , in the above embodiments, the method of removing the powder storage device 30 and then sending the pollen in it into the second sleeve bag 20 is adopted. Although the whole pollination process has been extremely simplified, there are still multiple steps. To further simplify the pollination process, on the basis of Embodiment One, this embodiment further improves the structure of the powder storage device 30. That is:

[0053] The powder storage device 30 includes a foldable bellows two 309 with openings at both ends. One end of the bellows two 309 is communicated with the second bag mouth 102, and the other end is matingly connected with the fourth bag mouth 202, and a detachable sealing cover two 3091 is provided.

[0054] The bellows two 309 adopts the same structure and material as the bellows one 2021, so that the bellows two 309 can also be stretched and bent. Then when pollinating, first remove the sealing cover two 3091 and the upper sealing cover of the fourth bag mouth 202, insert the bellows two 309 into the fourth bag mouth 202, so that the first sleeve bag 10 and the second sleeve bag 20 form a state of being interconnected and isolated from the outside. At this time, shake the male ear, and the pollen on the male ear directly enters the second sleeve bag 20 through the bellows two 309. At the same time, since there is no storage process, the probability of caking is also reduced, and thus a good pollination process is achieved.

[0055] It should be noted that the first sleeve bag 10 and the second sleeve bag 20 can also be connected through the bellows two 309 when putting on the sleeve bags. In this way, when pollinating, there is no need to operate each plant separately in sequence. Only by disturbing the corn plants on a large scale can the pollination process be achieved, which greatly simplifies the pollination steps and improves the pollination efficiency.

[0056] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
