Description

Technical Field

[0001] This utility model relates to the field of maize hybrid seed breeding technology, specifically to a high-efficiency hybrid seed breeding device in the process of maize variety selection. Background Technology

[0002] Corn seeds are reproductive bodies capable of growing into mature corn plants. They are formed from ovules through pollination and fertilization. There are various types of corn seeds, including conventional varieties, inbred lines, single-cross hybrids, double-cross hybrids, and triple-cross hybrids. Among them, hybrid corn seeds are the most common in the market due to their heterosis and significant yield-increasing effects. Genetically modified corn seeds are the future development trend, possessing excellent characteristics such as insect resistance and disease resistance.

[0003] In the process of maize breeding, breeders need to observe and evaluate the traits of the plants, including growth habits, plant type, ear type, grain type, color, yield, disease resistance, etc. Through field trials and laboratory analysis, they screen out combinations that do not perform well and eliminate inferior seeds. At the same time, they also need to conduct combining ability tests to evaluate the combining ability between different parent combinations in order to determine the best parent combination.

[0004] The corn breeding process usually requires placing seeds inside an incubator. However, existing incubators are inconvenient for personnel to observe and evaluate corn seedlings, and the seedlings tend to block each other, making it difficult to assess seedling traits. Therefore, this paper proposes an efficient hybrid seed breeding device for corn variety selection to address the existing needs. Utility Model Content

[0005] The purpose of this invention is to provide an efficient hybrid seed breeding device for maize variety selection. By setting a fixed frame inside the breeding box, and setting several breeding boxes inside the fixed frame, the multiple breeding boxes are arranged in a stepped manner. The maize seedlings are located inside the breeding boxes. Due to the height difference between two longitudinal breeding boxes and the separation of two transverse breeding boxes, the maize seedlings are given more growth space. At the same time, it is also convenient for personnel to observe and evaluate the seedlings, reducing the workload of breeding and solving the problems in the existing technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency hybrid seed cultivation device for maize variety breeding, comprising a cultivation box and a fixing frame, wherein the fixing frame is located inside the cultivation box, and a plurality of cultivation boxes are arranged inside the fixing frame; a water tank is arranged at the upper end of the cultivation box; a daylight lamp is arranged on the side of the cultivation box; a door panel is arranged on one side of the cultivation box; a support plate and a limiting plate are arranged inside the cultivation box; a plurality of atomizing nozzles are arranged below the water tank, with the water outlet of the atomizing nozzles located directly above the cultivation boxes; a bottom plate is arranged below the limiting plate; and one end of the support plate and the limiting plate are connected.

[0007] Preferably, at least two light lamps are provided, both of which are located above the incubation box and fixed to the side wall of the incubation box, with the light-emitting end of the light lamp facing the incubation box.

[0008] Preferably, the fixing frame includes a guide plate, a positioning plate and a baffle plate. One end of the positioning plate is connected to the guide plate, and the other end of the positioning plate is connected to the guide plate through a column. The positioning plate is located between the limiting plate and the bottom plate.

[0009] Preferably, the bottom of the guide plate is in contact with the support plate, the incubation box is located above the guide plate, the lower end of the guide plate is provided with a liquid storage chamber, and the side of the liquid storage chamber is provided with an opening and closing plate.

[0010] Preferably, the fixing frame includes a crossbar and a fixing plate, the crossbar and the fixing plate are connected, the incubation box is located between the crossbar and the fixing plate, the fixing plate has a slot inside, and a pressure plate is provided at the lower end of the fixing plate.

[0011] Preferably, the bottom of the culture box is provided with a through hole, and the side of the culture box is provided with a baffle and a stop block. The baffle is located above the slot, and the stop block is located at the junction of the crossbar and the fixing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model features a fixed frame inside a cultivation box, with several cultivation boxes arranged in a stepped manner. Corn seedlings are located within these cultivation boxes. The height difference between two vertically spaced cultivation boxes and the separation between two horizontally spaced boxes provide greater growth space for the corn seedlings. This also facilitates observation and evaluation of the seedlings, reducing the workload of breeding. Furthermore, a fixing plate with slots on the side of each cultivation box allows personnel to record information about the corn seeds within the corresponding cultivation box, facilitating tracking and management. This improves the efficiency of subsequent evaluation of corn seedling traits and contributes to the efficient and orderly conduct of breeding work.

[0014] 2. This utility model, after installing the cultivation box on a fixed frame, sets up a guide plate below the cultivation box, and a liquid storage chamber at the lower end of the guide plate. When personnel water the cultivation box through the atomizing nozzle, the organic soil inside the cultivation box absorbs some of the water, and the excess water falls through the through hole at the bottom of the cultivation box onto the guide plate, and then falls along the guide plate into the liquid storage chamber. Finally, personnel can open the opening and closing plate to collect the excess water, thereby avoiding the waste of water resources. At the same time, the fixed frame ensures that the corn seedlings can absorb sufficient nutrients while preventing the seedling roots from being soaked in water for a long time, avoiding the seeds from being soaked and rotting, improving the germination rate of corn seeds, and improving breeding efficiency.
