Description

Technical Field

[0001] The utility model relates to the technical field of tomato pollination, in particular to a novel pair of tweezers used for artificial emasculation and pollination of tomatoes. Background Art

[0002] Tomatoes are a typical self-pollinating crop. The first inflorescence of a tomato is usually borne between the eighth and ninth leaves of the plant, and an inflorescence is borne every 2-3 leaves thereafter. Usually, the inflorescence at the base blooms first, and then opens in sequence upwards. Tomatoes are bisexual flowers with hermaphroditic flowers. Common cultivated varieties have 5-6 petals and 5-6 stamens. The anthers are long and form a tube around the style. Each anther has a pollen sac on each side, which emits pollen when mature. The flowering process of each tomato flower includes four stages: budding, crown exposure, opening, and full bloom. The flowers bloom at irregular times throughout the day.

[0003] Currently, tomato breeding methods include sexual hybridization, male sterile line breeding, and dominant breeding. However, these methods generally require artificial emasculation and pollination. Tweezers are commonly used for artificial emasculation. When using ordinary tweezers, operators need to remove stamens one by one, requiring 5-6 detasselings per flower, which is time-consuming and laborious. In hybrid breeding, tweezers are also required to remove pollen from the side walls of the male parent's stamens. This process is difficult and the amount of pollen collected is limited. Therefore, each piece of pollen can only pollinate one style of the female parent, seriously affecting the efficiency of artificial pollination.

[0004] Therefore, it is urgent to provide a kind of tweezers that is convenient for artificial emasculation and can improve the pollen collection amount of tweezers. Utility Model Content

[0005] The purpose of the utility model is to provide a new type of tweezers for artificial emasculation and pollination of tomatoes, so as to solve the problem that the existing tweezers for artificial emasculation of tomatoes and Xining in the background art are very troublesome and the amount of pollen collected is small.

[0006] In order to achieve the above-mentioned purpose, the utility model proposes a new type of tweezers for artificial emasculation and pollination of tomatoes, comprising a left tweezers arm and a right tweezers arm symmetrically arranged with the left tweezers arm; wherein, one ends of the left tweezers arm and the right tweezers arm gradually approach each other to form a connecting end, and the other ends gradually move away from each other to form a clamping end, and an arc-shaped tweezers body is connected between the clamping end and the connecting end; a connecting spring is provided between the left tweezers arm and the right tweezers arm, and a pollen storage structure is provided on the clamping end.

[0021] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific implementations. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] The new tweezers for artificial emasculation and pollination of tomatoes in the present application can be used in occasions such as artificial emasculation and pollination of tomatoes, and of course can also be used in other similar application scenarios. The new tweezers for artificial emasculation and pollination of tomatoes are described in detail below.

[0023] See attached Figure 1 — Figure 3 The figure shows a schematic structural diagram of a preferred embodiment of a novel tweezers for artificial tomato emasculation and pollination according to the present application. The novel tweezers for artificial tomato emasculation and pollination comprise a left tweezers arm 1 and a right tweezers arm 2 symmetrically disposed with respect to the left tweezers arm 1. One end of the left tweezers arm 1 and the right tweezers arm 2 gradually approach each other to form a connecting end 3, and the other ends gradually move away from each other to form a clamping end 4. An arc-shaped tweezers body 5 is connected between the clamping end 4 and the connecting end 3. A connecting spring 6 is disposed between the left tweezers arm 1 and the right tweezers arm 2, and a pollen storage structure 7 is disposed on the clamping end 4.

[0024] The utility model increases the contact area between the operator's palm and the tweezers by setting the tweezers body 5 in an arc shape, and provides setting conditions for the arc groove; by setting the connecting spring 6, the elastic force between the left tweezers arm 1 and the right tweezers arm 2 is increased, the resetting force of the left tweezers arm 1 and the right tweezers arm 2 is increased, and the separation speed of the left tweezers arm 1 and the right tweezers arm 2 is improved, ensuring that the tomato can be castrated when the left tweezers arm 1 and the right tweezers arm 2 are separated; by setting the pollen storage structure 7, it is used to temporarily store the pollen of the male parent, increase the storage capacity of the pollen of each tweezers, and increase the ability to pollinate multiple stigmas after each pollen collection by the tweezers, thereby improving the pollination efficiency.

[0025] See attached Figure 1 — Figure 3 As shown, in the present invention, a through hole 31 is provided on the connecting end 3; the orthographic projection of the forceps body 5 on the outer wall plane is elliptical. The provision of the through hole 31 facilitates hanging the forceps; and by configuring the elliptical projection of the forceps body 5, the contact area between the left and right forceps arms and the human palm is increased, making it easier for the operator to hold the forceps.

[0026] See attached Figure 1 — Figure 3 As shown, in the present invention, the pollen storage structure 7 includes an enlarged portion 71 provided on the clamping end 4 and a storage groove 72 provided on the enlarged portion 71 .

[0027] The utility model is used to provide setting conditions for the storage slot 72 through the setting of the expansion part 71, increase the space of the storage slot 72, and enable the storage slot 72 to store more pollen; through the setting of the storage slot 72, it is used to store pollen.

[0028] See attached Figure 1 — Figure 3As shown, in the present invention, the expansion portion 71 is hemispherical; the storage groove 72 is a semi-spherical groove; and the plane of the expansion portion 71 is flush with the inner wall of the clamping end 4 .

[0029] The present invention ensures the maximum volume under the same radius by setting the expansion part 71 as a hemisphere, thereby ensuring that the storage slot 72 can obtain the maximum space; by setting the storage slot 72 as a semi-spherical slot, when the expansion part 71 is a sphere, the semi-spherical slot can ensure that the storage slot 72 occupies the maximum space; by limiting the expansion part 71 and the inner wall of the clamping end 4 to be flush, it is ensured that when the left and right tweezers arms are clamping, the object cannot be stably clamped due to uneven inner walls.

[0030] See attached Figure 1 — Figure 3 As shown, in the present invention, the tweezers body 5 of the left tweezers arm 1 and the right tweezers arm 2 are provided with a first arc groove 11 and a second arc groove 21. The present invention uses the first arc groove 11 and the second arc groove 21 to limit the position of the operator's fingers during operation, making it easier for the operator to pick up the tweezers.

[0031] It should be noted that the first arc groove 11 and the second arc groove 21 in the present application are staggered, so as to further conform to the human body's movements when holding tweezers, allowing staff to hold tweezers for a long time and reducing the operator's muscle fatigue.

[0032] See attached Figure 1 — Figure 3 As shown, the use process of the utility model is as follows:

[0033] The first step is to select the mother flower: the mother flower is a complete flower with green and white petals and yellow and green stamens within 4-5 days after budding. At this time, the stigma of the complete flower is relatively active, and the pollen in the stamens is immature and has no pollen vitality. Usually, after emasculation at this time, pollination can be carried out immediately, and there is no need to wait 1 to 2 days before pollination.

[0034] The second step is emasculation: the thumb and index finger cooperate to press the left tweezers arm 1 and the right tweezers arm 2, so that the two clamping ends 4 are close to each other, and then the clamping end 4 is slowly inserted along the gap at the bottom of the tubular stamen of the female parent. After inserting into the tubular stamen, the tweezers are slowly opened and the clamping end 4 of the tweezers is moved toward the bottom of the stamen. Then, the tweezers are immediately released, the connecting spring 6 is rebounded, and the left tweezers arm 1 and the right tweezers arm 2 are quickly separated to remove all stamens;

[0035] Step 3: Select the male parent flower: The male parent flower should be within 6-8 days of opening, with yellow petals and golden stamens. Use tweezers to gently remove pollen from the pollen sacs on the side walls of the stamens, observe their pollen shedding, and select flowers that have fully shed pollen. Note that the temperature and humidity conditions in the plant factory are different from those outdoors, so choose the time to collect pollen based on actual conditions.

[0036] Step 4: Pollination: Gently slide the notches of the storage slots 72 on the clamping end 4 from bottom to top over the pollen sacs on both sides of the male parent, allowing the pollen from the anthers to fall into the storage slots 72 of the tweezers. After collecting the pollen, apply the pollen to the stigma of the emasculated female parent, gently and evenly applying it several times, taking care not to damage the stigma. Usually, multiple styles can be pollinated in one pollen collection.

[0037] Step 5. Labeling: After pollination, mark the parents' information and pollination time on the label, circle the label rope into an "O" shape, and put it into the pedicel of the pollinated flower of the mother parent. Use one of the tweezers arms to support one side of the "O" shape to prevent the flower from falling off at the abscission layer, and slowly pull the label until it is firmly tied to the pedicel.

[0038] The above embodiments are intended to illustrate the present application, not to limit the present application. Any solution that is a simple transformation of the present application falls within the scope of protection of the present application.
