Description

Technical Field

[0001] The invention relates to the technical field of rice seedling selection and breeding, and in particular to a rice seedling breeding device for breeding multi-resistant japonica rice varieties in cold regions. Background Art

[0002] In the breeding of cold-region japonica rice varieties, seedling cultivation is a crucial link, and its cultivation quality directly affects the breeding effect. The traditional seedling cultivation method has many disadvantages and cannot meet the needs of refined and efficient breeding of cold-region multi-resistant japonica rice varieties.

[0003] First, the traditional cultivation device has a single structure, mostly simple open seedling trays, lacking reasonable planning and separation of the cultivation space. This causes seedlings of different varieties or different cultivation stages to be mixed together, making it difficult to carry out targeted management, easily causing variety confusion, increasing the difficulty of breeding, and failing to accurately implement operations such as fertilization, watering, and pest and disease control, affecting the consistency and stability of seedling growth.

[0004] Secondly, in terms of observing the growth of seedlings, traditional seedling trays are not specially designed, and workers need to frequently turn the seedlings or rely on experience to judge the growth status, which is inconvenient and easy to damage the seedlings. At the same time, the lighting conditions are difficult to control, and it is impossible to provide a suitable lighting environment for the seedlings, which is not conducive to their healthy growth.

[0005] Furthermore, the ventilation conditions of traditional seedling trays are poor. Poor air circulation can easily lead to excessive humidity in the seedling growth environment, breeding mold and bacteria, causing pests and diseases, seriously threatening the health of the seedlings and reducing the success rate of breeding. In addition, in terms of water management, the traditional method is usually overall watering or drainage, which cannot accurately control the water according to the actual needs of each seedling area, causing some seedlings to lack water while others are waterlogged and rotten. This is not conducive to the precise control of water for cold-region japonica rice seedlings under special climatic conditions, and it is difficult to cultivate high-quality japonica rice seedlings that adapt to cold environments and have multiple resistances. Summary of the invention

[0006] The purpose of the present invention is to provide a rice seedling cultivation device for breeding multi-resistant japonica rice varieties in cold regions to solve the following technical problems:

[0008] A cavity is formed in the center control of the reinforcing rib, a partition component is inserted in the cavity, a marking plate is inserted in the top end face of the partition component, and a water delivery component is inserted in the bottom end of the disk body.

[0009] As a further solution of the present invention, the dish body is rectangular and has a plurality of drainage holes at the bottom. The top edge of the dish body protrudes upward to form a frame, and the frame is connected to the dish cover.

[0010] As a further solution of the present invention, the fixing assembly includes a connecting rod, the connecting rod is fixed to both ends of the reinforcing rib, and one end of the connecting rod passes through the disc body and is threadedly connected to a fixing piece.

[0011] As a further solution of the present invention, the partition assembly includes a plurality of partition plates, and the partition plates are detachably disposed inside the tray body to divide the interior of the tray body into a plurality of seedling raising spaces.

[0012] As a further solution of the present invention, a transparent acrylic plate is provided at the connection between the partition plate and the sign board.

[0013] As a further solution of the present invention, the marking plate is an erasable whiteboard marking plate.

[0014] As a further solution of the present invention, the water delivery component includes a water tank, which is fitted at the bottom of the disk, with connecting pipes evenly distributed on the top of the water tank, and water inlet pipes and drainage pipes connected to the front and rear end faces of the water tank.

[0015] As a further solution of the present invention, the diameter of the connecting pipe is consistent with the inner diameter of the drainage hole opened at the bottom of the tray.

[0016] As a further solution of the present invention, the ventilation sunshade component includes a rotating rod, which is fixed on the inner side of the fixing component. The outer wall of the rotating rod is rotatably connected to a winding wheel, the outer wall of the winding wheel is wrapped with a sunshade net, and the end of the sunshade net is fixed with a support component.

[0017] As a further solution of the present invention, a spring is provided at the connection between the rotating rod and the winding wheel, and the inner ring of the spring is fixedly connected to the rotating rod, and the outer ring of the spring is fixedly connected to the winding wheel, a clamping block is fixed on one side of the support member, and a clamping groove matching the clamping block is opened on the other side of the support member.

[0018] Connected through card slot and card block.

[0019] Beneficial effects of the present invention:

[0020] 1. The tray is rectangular and has multiple drainage holes at the bottom, which can not only ensure the discharge of excess water, but also provide suitable humidity for the growth of seedlings. The upwardly protruding frame on the top edge is connected to the tray cover made of transparent acrylic board. On the one hand, the tray cover can effectively prevent external impurities from falling into the tray and affecting the seedlings. On the other hand, the transparent material makes it easy to observe the growth of the seedlings inside the tray at any time. At the same time, it can also provide certain light conditions for the seedlings. The tray cover can be opened for ventilation, fully meeting the seedlings' needs for the environment and creating a stable and suitable microclimate environment for the breeding of multi-resistant japonica rice varieties in cold regions.

[0021] 2. The multiple reinforcing ribs arranged on the top of the inner wall of the tray not only enhance the structural strength of the tray and make it more durable, but also the reinforcing ribs are hollow to form a cavity, in which the partition components can be removably plugged. The partition plates and the reinforcing ribs can divide the interior of the tray into multiple seedling raising spaces. This design facilitates the classification and cultivation of seedlings of different varieties or at different cultivation stages to avoid confusion, greatly improving the accuracy and efficiency of breeding work.

[0022] 3. The marking plate plugged into the top end face of the partition component is an erasable whiteboard. The marking plates on both sides can clearly and accurately record the cultivated seedling varieties and cultivation time, and a transparent acrylic plate is set at the connection between the partition plate and the marking plate. Researchers can view the recorded information at any time through the acrylic plate without opening the device, and then take targeted cultivation measures in a timely and accurate manner based on key information such as seedling varieties and growth time, such as reasonable fertilization to ensure nutrient supply at different growth stages, precise watering to maintain appropriate humidity, and effective disease and pest control, which greatly improves the cultivation effect and success rate.

[0023] 4. The water supply parts plugged into the bottom of the tray are ingenious. Each independent seedling unit is equipped with an independent water supply part at the bottom. The complete water supply system consists of a water tank, a connecting pipe, a water inlet pipe and a drainage pipe. The water tank provides guarantee for the water supply and temporary storage during the tray cultivation process. The connecting pipe cleverly uses the same inner diameter design as the drainage hole at the bottom of the tray to achieve smooth two-way flow of water between the water tank and the seedling unit, which can not only deliver water on demand but also drain water in time. By opening and closing the water inlet pipe and the drainage pipe, scientific researchers can accurately and flexibly regulate the water content of each seedling unit according to the water demand characteristics and actual growth conditions of different seedlings, avoiding the adverse effects of excessive or insufficient water on the growth of seedlings, and effectively ensuring the healthy and vigorous growth of cold-resistant japonica rice seedlings.

[0024] 5. The rotating rod of the ventilation sunshade is fixed on the inner side of the fixing part, and the winding wheel can rotate on the rotating rod, and a spring is provided at the connection. The outer wall of the winding wheel is wrapped with a sunshade net. When sunshade is needed, the sunshade net can be pulled out and fixed through the card slot and card block on the support part to unfold the sunshade net. When sunshade is not needed, the winding wheel automatically reels the sunshade net under the reaction force of the spring. This design can flexibly adjust the degree of sunshade according to the light intensity, which can not only avoid the damage of strong light to the seedlings, but also can timely retract the sunshade net when the light is insufficient to ensure that the seedlings get enough light.
