Description

Technical Field

[0001] This invention belongs to the field of sorghum breeding technology, and specifically relates to a sorghum seedling breeding device. Background Technology

[0002] Sorghum seedling breeding refers to the process of cultivating superior sorghum varieties under specific environmental conditions through seed propagation, genetic improvement, and other means. When using seed propagation for sorghum seedling breeding, floating trays or breeding racks are generally used. Compared to floating tray breeding, breeding racks have the advantages of simple operation and low cost. Furthermore, breeding racks allow for better control of environmental factors such as light and temperature, which is beneficial to the growth and development of sorghum seedlings.

[0003] Currently, common breeding racks include a support frame and multi-layered breeding trays that can be detachably connected to the support frame. Sprayers are installed between adjacent breeding trays, and the sprayers are connected to external pipes to spray water, nutrient solution or medicine onto sorghum seedlings through the pipes and sprayers. At the same time, temperature and humidity sensors are also installed on the support frame to adjust the temperature and humidity inside the breeding trays in a timely manner.

[0004] When using breeding racks to breed sorghum, nutrient solutions and water are sprayed onto the sorghum seedlings below through nozzles. This means that the nutrient solutions or water first act on the leaves of the sorghum seedlings, and then on their roots. If the breeding racks are moistened with a semi-dry mist, it is difficult to replenish the water to the roots of the sorghum seedlings, resulting in poor root development and affecting the growth of the entire plant. On the other hand, directly spraying rainwater can easily lead to excessive moisture inside the breeding racks, causing water accumulation on the leaves and resulting in disease. Summary of the Invention

[0005] The present invention aims to provide a sorghum seedling breeding device to better achieve differentiated adjustment of humidity above and below the breeding tray.

[0006] This invention discloses a sorghum seedling breeding device, comprising a support frame and multiple breeding trays detachably connected to the support frame. The outer wall of the support frame is provided with pipes connected to a water pump. Atomizing nozzles are distributed above each breeding tray, and the atomizing nozzles are connected to the pipes. A stop valve is provided between the pipes and the atomizing nozzles. A water storage chamber is provided in the wall at the bottom of each breeding tray, connected to the pipes. A valve is provided between the pipes and the water storage chamber. Frustum-shaped guide blocks are evenly distributed at the bottom of the inner surface of each breeding tray. Each guide block has a through-hole, and the bottom of the through-hole is connected to a water guide pipe. The other end of the water guide pipe is connected to the water storage chamber. The height of the guide blocks is 1 / 2 to 2 / 3 of the internal height of the breeding tray. A drain pipe is connected to the bottom of the water storage chamber.

[0007] The working principle and beneficial effects of this solution are as follows: When water needs to be replenished for the sorghum seedlings in the breeding tray, water is supplied to the atomizing nozzles through pipes. The atomizing nozzles produce a semi-dry mist to provide moisture to the leaves of the sorghum seedlings, preventing excessive water accumulation on the leaves. Water is also supplied to the water storage chamber through pipes. The water gradually rises from bottom to top in the water storage chamber and finally enters the soil in the breeding tray through the water outlet. Because the water first accumulates in the water storage chamber, the water output from each water outlet is consistent, improving the balance of water supply. In addition, since the height of the guide block is 1 / 2 to 2 / 3 of the internal height of the breeding tray, the water can move synchronously to the upper and lower sides, preventing the soil at the top from becoming too wet. Moreover, some of the water in the water storage chamber can continue to act on the soil in the breeding tray to provide humidity for the sorghum seedlings. When the humidity in the breeding tray is sufficient, the water in the water storage chamber can also be drained through the drain pipe.

[0008] Furthermore, the bottom wall of the breeding tray is equipped with a collection cavity, located above the water storage cavity. Drainage holes are evenly distributed at the bottom of the breeding tray, connecting to the collection cavity, which is also connected to a drain pipe. Through the collection cavity, when there is excessive moisture in the soil, it can enter the collection cavity through the drainage holes and accumulate. The accumulated moisture can then be used to provide water for the sorghum seedlings or drained through the drain pipe.

[0009] Furthermore, the bottom of the breeding tray is provided with geotextile, weed control fabric, or drip irrigation fabric. By setting up geotextile, weed control fabric, or drip irrigation fabric, excess water can enter the collection cavity normally, and soil can be prevented from clogging the outlet or leakage holes.

[0010] Furthermore, the water outlet includes a guide hole and multiple overflow holes. The multiple overflow holes are evenly distributed on the top of the guide block and communicate with the top of the guide hole. The bottom of the guide hole is connected to the water guide pipe. Setting the top of the water outlet as multiple overflow holes helps to reduce the impact of the water on the soil.

[0011] Furthermore, the support frame is U-shaped, with a top cover and windproof cloths on both sides of the opening. These windproof cloths can be opened or closed to adjust ventilation, humidity, and temperature.

[0012] Furthermore, gauze is installed on both sides of the opening of the support frame, positioned between the windbreak cloth and the seed tray. The gauze reduces direct sunlight on the sorghum seedlings when the windbreak cloth is open.

[0013] Furthermore, a temperature sensor is installed on the support frame. This temperature sensor allows for real-time monitoring of the temperature within the breeding device, enabling timely adjustments.

[0014] Furthermore, humidity sensors are installed on both the support frame and inside the breeding tray. Controlled by these humidity sensors, and in conjunction with the atomizing nozzles and water outlets, differentiated adjustments to the humidity inside and outside the breeding tray are easily achieved.

[0015] In this application, the control of temperature, humidity and light can be achieved by using an environmental controller, which is a conventional technology and will not be described in detail here. Attached Figure Description
