Description

Technical Field

[0001] The present invention relates to the technical field of rice breeding, and more specifically, to a breeding device for hybrid drought-resistant rice. Background Art

[0002] Hybrid rice refers to the selection of two rice varieties with certain genetic differences and complementary excellent traits for hybridization to produce the first-generation hybrid with heterosis, which is hybrid rice. Generally, hybrid rice only refers to the first-generation hybrid formed by the hybridization of two sterile lines and restorer lines with the same genetic background. The widely promoted hybrid rice mainly uses the rice male sterile line as a genetic tool. At present, many regions are relatively arid. In order to grow rice in arid regions, high-yield common rice is hybridized with drought-resistant rice to obtain hybrid high-yield and drought-resistant hybrid rice. Since the offspring of hybridization are not completely the same, it is necessary to separately cultivate and screen the hybridized seeds to select rice with drought resistance and high yield.

[0003] A cultivation room for rice breeding disclosed in the patent with the publication number of CN103461087B belongs to the technical field of agricultural seedling raising. It solves the technical problems that the existing cultivation room for rice breeding cannot efficiently cultivate rice suitable for surviving and growing in deep water. The cultivation room for rice breeding of the present invention is characterized in that the cultivation room includes a cultivation house and a cultivation pool. The cultivation pool is located inside the cultivation house. A number of biological floating beds are fixed in the cultivation pool. The biological floating beds are clamped between the corresponding slot one and slot two. A temperature-sensitive sensor one is fixed in the cultivation pool. The temperature-sensitive sensor one is connected to a controller through a circuit. The controller is connected to an electromagnetic valve. The present invention has the advantages of keeping the rice in the best growth environment all the time, accelerating the growth rate of the rice, and reducing the breeding cycle.

[0004] At present, a rice cultivation box is often used for the breeding of hybrid rice. It can not only better care for the growth of rice, but also simulate the corresponding environment according to needs. Hybrid rice can also receive the pollen of other plants, resulting in offspring different from the mother plant. By self-pollination, the offspring are ensured to be the same as the mother plant. Since the cultivation box is a closed environment, the pollination of the hybrid rice in the cultivation box often needs to be carried out manually. However, the current cultivation box is often a whole, and it is often necessary to open the entire cultivation box, which causes all the rice plants in the cultivation box to be exposed to the outside, resulting in cross-pollination between the plants in the cultivation box and the offspring being different from the mother plant. Summary of the Invention

Detailed implementation manners

[0032] 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.

[0033] such as Figure 1 , Figure 2 , Figure 3 , Figure 7 , Figure 9 , Figure 10 and Figure 11As shown in the figure, the present invention provides a breeding device for hybrid drought-resistant rice, including a planting box 11, a height adjustment box 12, an operation box 13 and a top cover 14. The height adjustment box 12 is installed at the upper end of the planting box 11, the operation box 13 is installed at the upper end of the height adjustment box 12, and the top cover 14 is installed at the upper end of the operation box 13. The interiors of the planting box 11, the height adjustment box 12, the operation box 13 and the top cover 14 are all separated by partitions into multiple inner cavities, and one hybrid rice plant is planted in each cavity, so as to prevent the hybrid rice in the cultivation box from pollinating each other. The materials of the height adjustment box 12, the operation box 13 and the top cover 14 are all transparent acrylic plates, and an auxiliary ear picking mechanism and a fixing mechanism are arranged in the inner cavity of the operation box 13;The auxiliary ear-taking mechanism includes a first push plate 211. The first push plate 211 is installed inside the inner cavity of the operation box 13. The first push plate 211 is designed in an arc shape, which can better protect the rice ears when pushing the rice ears. On the left and right sides of the lower end of the first push plate 211, there are fixedly connected with sliders 212. On the left and right sides of the lower end of the inner cavity of the height adjustment box 12, there are respectively provided with first chutes 213 that cooperate with the sliders 212. The sliders 212 are engaged in the first chutes 213. On the front and rear ends of the operation box 13, there are respectively provided with operation windows 214 corresponding to the inner cavity of the operation box 13. Inside the operation windows 214, there is rotatably connected a transparent door panel 215. Inside the sliders 212, there is rotatably connected a first connecting rod 216. The upper end of the first connecting rod 216 is rotatably connected to the upper end of the inner side of the transparent door panel 215. On the upper end of the outer side of the transparent door panel 215, there is fixedly connected a handle 217. When self-pollination needs to be carried out on a certain hybrid rice plant in the cultivation box, first pull the handle 217, so that the transparent door panel 215 rotates and the operation window 214 is opened. When the transparent door panel 215 rotates, at this time, the slider 212 will be pulled forward through the first connecting rod 216, and the first push plate 211 moves forward to push the rice ears of the plants in this chamber of the operation box 13 forward. When the transparent door panel 215 is completely opened, at this time, the first push plate 211 pushes the rice ears to the operation window 214, so as to facilitate the pollination treatment of the rice ears in the chamber. In the middle of the first chute 213, there is fixedly connected a guiding rod 218. The guiding rod 218 is inserted through the middle of the slider 212. One end of the guiding rod 218 away from the transparent door panel 215 is sleeved with a first spring 219. One end of the first spring 219 is fixedly connected to the inner wall of the first chute 213 away from the transparent door panel 215, and the other end of the first spring 219 is fixedly connected to the slider 212. When pulling the slider 212 forward through the first connecting rod 216 when opening the transparent door panel 215, the first spring 219 is stretched. After the pollination is received, through the rebound of the first spring 219, the transparent door panel 215 can be automatically rotated and closed. Due to the elastic force of the first spring 219, it can also prevent the transparent door panel 215 from automatically opening without external force. On the upper sides of the left and right ends of the first push plate 211, there are respectively rotatably connected with dampers 220. The other ends of the left and right dampers 220 are respectively rotatably connected to the middle parts of the left and right first connecting rods 216. Through the dampers 220, it can be avoided that when the first spring 219 rebounds, the elastic force is too large, resulting in the closing speed of the transparent door panel 215 being too fast and causing damage to the transparent door panel 215 and the operation box 13;

[0034] The auxiliary ear-taking mechanism further includes a second push plate 221. The upper end of the first push plate 211 is rotatably connected to the second push plate 221. The second push plate 221 is designed in an arc shape. The left and right sides of the upper end of the second push plate 221 are rotatably connected to second connecting rods 222 respectively. The other ends of the second connecting rods 222 on the left and right sides are respectively rotatably connected to the upper ends of the first connecting rods 216 on the left and right sides. When the transparent door panel 215 is opened, the rotation of the first connecting rod 216 will pull the second connecting rod 222, so that the second connecting rod 222 pulls the second push plate 221 to rotate and bend the rice ears. When the transparent door panel 215 is completely opened, the second push plate 221 completely pushes the rice ears out of the operation box 13 through the operation window 214, which further facilitates the self-pollination of the rice ears of the plant. The upper end of the inner side of the transparent door panel 215 is fixedly connected with a mounting post 223. The other end of the mounting post 223 is fixedly connected with a third push plate 224. The third push plate 224 is arranged in an inclined shape. During the closing process of the transparent door panel 215, first, the third push plate 224 will push the rice ears into the operation box 13 to prevent the rice ears from being clamped between the closing transparent door panel 215 and the outside of the operation box 13, resulting in damage to the rice ears of the hybrid rice and affecting the yield.

[0035] The fixing mechanism includes a fixing block 311. The fixing block 311 is fixedly connected to the front end of one side of the inner cavity of the operation box 13. The fixing block 311 is located in the first sliding groove 213. The front end of the operation box 13 is provided with a second sliding groove 312 that cooperates with the fixing block 311. The lower end of the second sliding groove 312 is fixedly connected with a second spring 313. The lower end of the second spring 313 is fixedly connected to the inner wall of the lower end of the second sliding groove 312. The front end of the fixing block 311 is fixedly connected with a mounting rod 314. The outer end of the mounting rod 314 is fixedly connected with a pressing plate 315. The lower end of the second sliding groove 312 on the same side as the fixing block 311 is provided with a fixing card slot 317 that cooperates with the fixing block 311. The upper end of the fixing block 311 is designed in a trapezoidal shape. The front end of the sliding block 212 is provided with a guiding groove 316 that cooperates with the fixing block 311. When the transparent door panel 215 is opened, the sliding block 212 moves forward. When the sliding block 212 contacts the fixing block 311, first, the fixing block 311 is pushed downward through the guiding groove 316. When the handle 217 of the sliding block 212 moves to directly above the fixing block 311, at this time, the second spring 313 pushes the fixing block 311 into the fixing card slot 317, thereby locking and fixing the sliding block 212, preventing the elastic force of the first spring 219 from pulling the sliding block 212 to move, and further fixing the open state of the transparent door panel 215. When it is necessary to close the transparent door panel 215, press the pressing plate 315 downward. The fixing block 311 is moved downward through the mounting rod 314, so that the fixing block 311 disengages from the fixing card slot 317, so that the first spring 219 can pull the sliding block 212 to move backward, causing the transparent door panel 215 to automatically close.

[0036] As Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 shown, the planting box 11 includes a base 111. A soil planting groove 112 is inserted in the middle of the base 111. A base 113 is fixedly connected above the soil planting groove 112 at the upper end of the base 111. Planting holes 114 corresponding to the chambers of the height adjustment box 12 are opened in the middle of the base 113. Installation grooves 115 are opened at the upper ends of the base 113, the height adjustment box 12, and the operation box 13. The lower ends of the height adjustment box 12, the operation box 13, and the top cover 14 are respectively clamped in the installation grooves 115 at the upper ends of the base 113, the height adjustment box 12, and the operation box 13. By setting the cultivation box as a spliced type, the height of the entire cultivation box can be adjusted by adding the height adjustment box 12 according to the height of the hybrid rice plants, and the splicing operation is simple, thereby improving the practicability and applicability of the device. One end of the soil planting groove 112 is fixedly connected with a pouring groove 116. A water guide pipe 117 is fixedly connected inside the soil planting groove 112. One end of the water guide pipe 117 communicates with the pouring groove 116. Multiple groups of drainage holes 118 are opened on the water guide pipe 117. The other end of the soil planting groove 112 is fixedly connected with a drainage groove 119. A drainage port 120 is opened between the soil planting groove 112 and the drainage groove 119. The depth of the drainage groove 119 is greater than the depth of the soil planting groove 112. Adding water in the pouring groove 116, it is evenly discharged into the soil in the soil planting groove 112 through the water guide pipe 117 and the drainage holes 118, so that the soil in the soil planting groove 112 can be quickly replenished with water, and the moisture of the soil can be discharged into 109 through the drainage port 120, so that a dry environment can be better simulated;

[0037] Inside the top cover 14, a fluorescent lamp 4 is installed. Inside the soil planting groove 112, a soil humidity sensor 5 is installed. On the outer wall of the drainage groove 119, a control panel 6 is installed. The control panel 6 is composed of operation buttons, a control module, a display module, and a storage module. The model of the control module can be CJ-1, and a data processing chip is provided inside the control module. The model of this data processing chip can be AD8352ACPZ. The model of the display module can be HYWEI1602-1, and the model of the storage module can be MC291. The output end of the operation button is electrically connected to the input end of the control module through a wire. The input end of the fluorescent lamp 4 is electrically connected to the input end of the control module inside the control panel 6 through a wire. The output end of the soil humidity sensor 5 is electrically connected to the input end of the data processing module of the control panel 6 through an electrical signal. Through the control panel 6, the fluorescent lamp 4 can be controlled, so that the hybrid rice in the cultivation box can be supplemented with light. Moreover, the soil humidity sensor 5 transmits the humidity information of the soil in the soil planting groove 112 to the data processing module of the control panel 6 in real time. Through the display module of the control panel 6, the soil humidity in the soil planting groove 112 can be observed in real time, so as to judge whether the soil humidity in the soil planting groove 112 meets the requirements of breeding.

[0038] Working principle of the present invention:

[0039] First, put the soil for cultivating hybrid rice into the soil planting groove 112, and insert the soil planting groove 112 into the base 111. Plant the hybrid rice seeds to be selected into the soil in the soil planting groove 112 through the planting holes 114 respectively. Snap the height adjustment box 12 into the installation groove 115 at the upper end of the base 113, and then snap the lower end of the operation box 13 into the 015 at the upper end of the height adjustment box 12. Finally, snap the lower end of the operation box 13 into the 015 at the upper end of the height adjustment box 12. At this time, the assembly of the cultivation box and the planting of hybrid rice seeds are completed. Add water to the pouring groove 116, and it is evenly discharged into the soil in the soil planting groove 112 through the water guide pipe 117 and the drain holes 118, quickly replenishing the soil in the soil planting groove 112. The moisture of the soil can be discharged into the 109 through the drain port 120 to simulate a dry environment. Control the opening and closing of the fluorescent lamp 4 through the control panel 6 to supplement light to the plants. Moreover, the moisture of the soil in the soil planting groove 112 can be monitored in real time through the soil humidity sensor 5 to ensure that the soil humidity in the soil planting groove 112 meets the dry environment;

[0040] When the rice plants need to be pollinated during the heading stage, first pull the handle 217, causing the transparent door panel 215 to rotate, and the operation window 214 is opened. When the transparent door panel 215 rotates, at this time, the first connecting rod 216 will pull the slider 212 to move forward, so that the first spring 219 is stretched, and the first push plate 211 moves forward to push the rice panicles of the plants in the chamber of the operation box 13 to move forward. At the same time, the rotation of the first connecting rod 216 will pull the second connecting rod 222, so that the second connecting rod 222 pulls the second push plate 221 to rotate, bending the rice panicles. When the slider 212 contacts the fixed block 311, first push the fixed block 311 to move downward through the guide groove 316. When the transparent door panel 215 is completely opened and the handle 217 of the slider 212 moves to directly above the fixed block 311, at this time, the second spring 313 pushes the fixed block 311 to snap into the fixed card slot 317, thereby locking and fixing the slider 212. At this time, the first push plate 211 pushes the rice panicles to the operation window 214, and the second push plate 221 completely pushes the rice panicles out of the operation box 13 through the operation window 214. At this time, quickly perform artificial pollination on the rice panicles. After the pollination is completed, press down the pressing plate 315, and the fixed block 311 moves downward through the mounting rod 314, so that the fixed block 311 disengages from the fixed card slot 317, so that the first spring 219 can pull the slider 212 to move backward, and drive the transparent door panel 215 to close and seal the operation window 214 through the first connecting rod 216, and pollinate the plants in each chamber of the first chute 213 in turn;

[0041] Finally, when the rice grains are mature, by observing and selecting, the hybrid rice that meets the requirements can be selected. After cutting off the rice panicles that meet the requirements, the next generation of cultivation can be carried out.
