Description

Technical Field

[0001] This utility model relates to the field of isolation windproof cover technology, specifically to a cruciferous hybrid breeding isolation windproof cover. Background Technology

[0002] In the process of hybridization breeding of cruciferous plants, insect pollination and natural wind are key interfering factors affecting the purity of the breeding. During hybridization breeding, it is necessary to strictly control the pollen dispersal path of the male and female parents to avoid the mixing of pollen from non-target varieties. Insects in nature can unintentionally bring pollen from other plants into the breeding area by attaching or carrying pollen on their bodies, which can lead to phenotypic segregation in the hybrid offspring and reduce the purity of the breeding and the stability of the target trait. Therefore, it is necessary to isolate the breeding area during the breeding process.

[0003] Most isolation devices use a simple frame and mesh sewn together structure, which is prone to frame deformation or overall displacement under wind force, resulting in insufficient isolation effect. In addition, the bottom of the isolation device is in direct contact with the ground and lacks a sealing structure, allowing insects to easily enter the isolation area through the gap between the device and the ground, affecting the hybridization effect. Utility Model Content

[0029] 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.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a windproof isolation cover for cruciferous hybrid breeding, including a first positioning rod 1, a second positioning rod 2, a first connecting rod 3, a second connecting rod 4, a first isolation net 5, an inner dividing net 6, a second isolation net 7, a fixing nail 8, a dividing plate 9, a fixing rod 10, a first extension net 11, a counterweight block 12, a second extension net 13, and a counterweight tube 14.

[0031] A fixing nail 8 is fixedly installed at the lower end of the first positioning rod 1. A partition plate 9 is fixed on the outer surface of the first positioning rod 1. A fixing rod 10 is rotatably installed on the surface of the partition plate 9. Three fixing rods 10 are arranged in a ring at equal intervals on the surface of the partition plate 9. The fixing nail 8, the partition plate 9 and the fixing rod 10 form a positioning structure. The positioning structure is respectively set on the surface of each first positioning rod 1 and second positioning rod 2.

[0032] like Figure 4 and Figure 5 As shown, according to the breeding area plan, positioning rod 1 and positioning rod 2 are installed. The fixing nail 8 at the lower end of positioning rod 1 is inserted into the ground to fix positioning rod 1 perpendicular to the ground. The fixing rod 10 on the surface of the partition plate 9 is rotated, and the fixing rod 10 expands outward and contacts the ground to form a triangular support structure, further fixing positioning rod 1 and increasing its windproof effect. Similarly, positioning rod 2 is installed and fixed. The first support unit formed by positioning rod 1 and the second support unit formed by positioning rod 2 are installed in the designated positions, so that the first support unit and the second support unit form a rectangular partition barrier around the breeding area, separating the hybrid breeding area from the external environment and preventing external insects from interfering with the hybrid breeding of cruciferous plants.

[0033] Positioning rod 1 is a round rod structure. Two symmetrically arranged positioning rods 1 form a support unit 1. A positioning rod 2 is located on one side of the positioning rod 1. The upper surface of the positioning rod 2 has a U-shaped notch. Two symmetrically arranged positioning rods 2 form a support unit 2. Two support units 1 are arranged in parallel. Two support units 2 are arranged in parallel between the two support units 1. The support units 1 and 2 form the basic support structure of the device. A connecting rod 3 is located between the two positioning rods 1 within the support unit 1. The connecting rod 3 is a wide strip of iron wire. A connecting rod 4 is located on one side of the connecting rod 3. The connecting rod 4 is also made of iron wire. The structure includes two parallel connecting rods 4 arranged vertically. The two connecting rods 4 are fixedly connected to both sides of the notch on the upper surface of the positioning rod 2 in the second support unit. The first isolation net 5 is sewn into the arch structure formed by the first support unit and the first connecting rod 3. The first isolation net 5 is installed in each of the two first support units. The surface of one of the first isolation nets 5 is fitted with a partition net 6 through a zipper structure. The second isolation net 7 is set in the arch structure formed by the second support unit and the second connecting rod 4. The second isolation net 7 passes through the notch on the surface of the positioning rod 2 and between the two connecting rods 4. The two ends of the second isolation net 7 are fixedly connected to the surfaces of the first connecting rods 3 on both sides.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, after the installation of positioning rod 1 and positioning rod 2, the connecting rod 3 and connecting rod 4, which are connected to positioning rod 1 and positioning rod 2 respectively, are installed simultaneously. The isolation net 5 connected to the surface of the support unit and connecting rod 3, and the isolation net 7 set on the surface of the support unit and connecting rod 4 are deployed as positioning rod 1 and positioning rod 2 are installed, forming a separation barrier around the breeding area to avoid external interference. When breeders need to enter the breeding area, they use the inner net 6 to enter and exit the breeding area. The inner net 6 is opened and closed by a zipper to enter and exit the breeding area.

[0035] The lower surfaces of isolation net 5 and isolation net 7 are respectively provided with extension structures. The extension structures increase the fit between the device and the ground through extension net 11 and extension net 13. The extension structure includes extension net 11 and extension net 13. The upper end of extension net 11 is fixedly connected to the lower end of isolation net 5. The lower end of extension net 11 is sewn to a counterweight block 12. The lower end of extension net 13 is sewn to a counterweight tube 14. The inside of counterweight tube 14 is filled with gravel counterweight. The diameter of counterweight tube 14 is smaller than the notch width on the surface of positioning rod 2. The upper end of extension net 13 is fixedly connected to the upper end of isolation net 7.

[0036] like Figure 1 and Figure 6 As shown, during the isolation of the breeding area by the device, isolation net 5 and isolation net 7 isolate the breeding area. The extension net 11 below the isolation net 5 hangs down to the ground under the gravity of the counterweight 12. At the same time, the extension net 13 below the isolation net 7 also hangs down to the ground under the gravity of the counterweight tube 14. This makes the extension net 11 and extension net 13 close to the ground, and the weight reduces the gaps at the bottom of the device, preventing insects from the outside from entering the breeding area through the bottom gaps.

[0037] Working principle: When using this cruciferous hybridization breeding isolation windproof cover, the fixing nails 8 at the lower ends of positioning rod 1 and positioning rod 2 are inserted into the ground, thereby completing the installation of support unit 1 and support unit 2. This causes isolation nets 5 and 7 on the surface to form a rectangular isolation structure around the cruciferous breeding area, preventing external insects from affecting the hybridization breeding process of cruciferous plants. Meanwhile, the counterweight block 12 at the lower end of extension net 11, as well as extension net 13 and the counterweight tube 14 at the lower end of extension net 13, are in close contact with the ground, thereby reducing the gap between the device and the ground, preventing insects from entering the breeding area through the gaps, and increasing the overall practicality.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
