Technical Field
[0001] This utility model relates to the field of maize breeding technology, and more specifically, to an isolated maize breeding pollination pack. Background Technology
[0002] Isolation pollination bags for maize breeding, typically in the form of pollination bags or isolation bags, play a significant role in maize breeding. Their main purpose is to effectively control pollination: isolation pollination bags can separate the male and female ears of maize, preventing interference from foreign pollen and ensuring that only the desired pollen can come into contact with the female or male ears, thereby effectively controlling the pollination process.
[0003] Among existing published documents, patent publication number CN215935846U discloses a breeding isolation cover for maize breeding. This technology connects a water collection tank to a water outlet pipe at the top, with a water pump installed on the outer wall of the outlet pipe. A water box is fixedly connected to the rear end of the isolation cover, thus achieving the effect of conveniently collecting and storing rainwater during maize breeding and facilitating the use of stored rainwater to irrigate the maize inside the isolation cover. This solves the problem of high labor intensity and wasted time caused by the need for manual water transportation for irrigation in existing maize breeding processes using isolation covers. However, this technology still has the following drawbacks.
[0004] During the pollination process in maize breeding, an isolation envelope is needed to cover the pollen and prevent other pollen from affecting the pollination. However, even after the pollination is isolated, other pollen can still enter through the larger openings in the pollination area, severely affecting the isolation effect of maize breeding and resulting in poor isolation.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] As attached Figure 1 - Appendix Figure 5 The diagram shows an isolated corn breeding pollination pack, which is equipped with a pollination sealing component. The pollination sealing component can limit the binding rope 3 through the rubber bottom ring 5 and the rubber top ring 7, so as to carry out all-round isolated pollination breeding of corn, resulting in better pollination sealing effect and better isolation effect of corn breeding pollination. The specific structural settings of the pollination sealing component are as follows.
[0023] In this technical solution, as shown in the appendix Figure 1 - Appendix Figure 3 As shown, a pollination tube 2 is fixedly connected to the upper surface of the kraft paper package 1, and a plastic bag hopper 8 is fixedly connected to the top of the pollination tube 2. A pollination sealing component is provided on the outer wall of the plastic bag hopper 8. The pollination sealing component includes a binding rope 3 fixedly installed on the outer wall of the plastic bag hopper 8, and also includes a plug connector 4, a rubber bottom ring 5, a spacer 6, a rubber top ring 7, a dispersion hopper 9, and multiple dispersion strips 10.
[0024] The connector 4 is fixed to one end of the binding rope 3. The rubber bottom ring 5 is located above the binding rope 3 and fixed to the outer wall of the plastic bag hopper 8. The spacer 6 is fixed to the upper surface of the rubber bottom ring 5, and the rubber top ring 7 is fixed to the top of the spacer 6. The rubber top ring 7 is fixedly connected to the plastic bag hopper 8. The dispersion hopper 9 is fixed to the inner wall of the kraft paper package 1. Multiple dispersion strips 10 are fixed to the inner wall of the dispersion hopper 9, and the multiple dispersion strips 10 are arranged in a circular, equidistant distribution. The diameter of the inner wall of the top of the plastic bag hopper 8 is smaller than the diameter of the inner wall of its bottom. The inner walls of the plastic bag hopper 8 and the pollination tube 2 are both smooth surfaces. The cross-sectional shape of the rubber top ring 7 is circular, and the cross-sectional shape of the rubber bottom ring 5 is circular. The multiple dispersion strips 10 are arranged in a circular, equidistant distribution, and there is a gap between each adjacent dispersion strip 10.
[0025] In this technical solution, as shown in the appendix Figure 4 As shown, a reinforcing ring 11 is fixedly connected to the outer wall of the kraft paper package 1 near its top. Multiple fiber strips 12 are fixedly installed on the lower surface of the reinforcing ring 11. A limiting strip ring 13 is installed at the bottom end of the fiber strip 12. The limiting strip ring 13 is fixedly connected to the fiber strip 12 so that the reinforcing ring 11, the fiber strip 12 and the limiting strip ring 13 can all provide reinforcement support to the outside of the kraft paper package 1. The kraft paper package 1 has a better wind resistance and is not easily deformed or damaged.
[0026] In this embodiment, when using the isolated corn breeding pollination kit, the kraft paper package 1 is placed over the corn breeding pollination area, and then the pollination tube is inserted into the plastic bag hopper 8, entering the pollination tube 2 through the plastic bag hopper 8, and then entering the kraft paper package 1 through the pollination tube 2. Then, the connector 4 is pulled, and the connector 4 drives the binding rope 3. The connector 4 is inserted into the gap between the spacer 6 and the plastic bag hopper 8, and the binding rope 3 is limited by the rubber bottom ring 5 and the rubber top ring 7. Then the binding rope 3 is bound to the plastic bag hopper 8, so that the plastic bag hopper 8 is firmly bound and locked to the outer wall of the pollination pipe. The pollen is poured into the pollination tube 2 and enters the dispersion hopper 9 through the pollination tube 2. The multiple dispersion strips 10 on the dispersion hopper 9 achieve dispersion pollination, and the powder is dispersed into the inside of the kraft paper package 1. This can achieve all-round isolation pollination breeding of corn, and the isolation effect of corn breeding pollination is better. At the same time, the limiting strip ring 13 provides support for the fiber strip 12, and the fiber strip 12 supports the reinforcing ring 11. The reinforcing ring 11, the fiber strip 12 and the limiting strip ring 13 all provide reinforcement support for the outside of the kraft paper package 1, and the kraft paper package 1 has a better wind resistance isolation effect.
[0027] In this technical solution, as shown in the appendix Figure 5 As shown, a rubber spacer ring 15 is fixedly connected to the outer wall of the kraft paper package 1 near its bottom end. A limiting and locking assembly is provided above the rubber spacer ring 15. The limiting and locking assembly includes a rubber shrink ring 14 disposed above the rubber spacer ring 15, and the rubber shrink ring 14 is fixedly connected to the kraft paper package 1. A binding rope 16 is provided between the rubber shrink ring 14 and the rubber spacer ring 15, and the binding rope 16 is slidably connected to the kraft paper package 1. A pull block 17 is fixedly connected to one end of the binding rope 16, and a sleeve block 18 is slidably connected to the outer wall of the binding rope 16. The rubber shrink ring 14 and the rubber spacer ring 15 are symmetrically arranged about the binding rope 16, and the outer wall of the binding rope 16 is a smooth surface.
[0028] In this embodiment, when using the isolated corn breeding pollination bag, one hand holds the sleeve block 18 and the other hand holds the pull block 17. Pulling the pull block 17 causes the binding rope 16 to move. The binding rope 16 slides on the inner wall of the sleeve block 18, and the sleeve block 18 squeezes the kraft paper package 1. In this way, the binding rope 16 binds and locks between the rubber spacer ring 15 and the rubber shrink ring 14. Thus, the bottom end of the kraft paper package 1 can adhere to the outer wall of the corn breeding plant, thereby achieving limiting binding of the corn breeding plant.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
