Description

Technical Field

[0001] This utility model belongs to the field of agricultural planting technology, and in particular relates to a corn seed germination rate detection device. Background Technology

[0002] In agriculture, corn is an important food and cash crop, and the germination rate of its seeds directly affects the yield and quality of the crop. Therefore, accurate and rapid detection of corn seed germination rate is of great significance for guiding agricultural production and improving crop yield.

[0003] Traditional methods for detecting corn seed germination rate typically involve manual counting. This involves placing a certain number of corn seeds on moist filter paper or potting soil, cultivating them under suitable environmental conditions, and then counting the number of germinated seeds after a certain period of time to calculate the germination rate.

[0004] However, this method has the following drawbacks: Low efficiency: Traditional methods require processing seeds individually and counting them manually, a tedious and time-consuming process, especially when processing large quantities of seeds. Limited accuracy: Manual counting is susceptible to subjective factors such as visual fatigue and counting errors, leading to inaccurate results. Furthermore, traditional methods struggle to ensure stable placement of individual seeds; multiple seeds crowded in the same area may interfere with each other, further affecting the accuracy of the results. Inconvenient operation: Traditional methods lack effective auxiliary tools during seed placement, cultivation, and counting. Operators must directly contact the seeds and culture medium, which is not only inconvenient but may also damage or contaminate the seeds.

[0005] To address the aforementioned problems and improve the efficiency and accuracy of corn seed germination rate detection, this invention presents a corn seed germination rate detection device.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] The purpose of this invention is to provide a corn seed germination rate detection device, which achieves stable placement of single seeds and batch detection through a rectangular array of conical through-holes.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] This utility model is a corn seed germination rate detection device, including a breeding tray and multiple insert plates; the breeding tray has conical through holes arranged in a rectangular array; and two rectangular insert holes perpendicular to the axis of the conical through holes are opened on one side of the breeding tray.

[0010] As a preferred embodiment of this utility model, the distance between the small-diameter end of the tapered through hole and the adjacent rectangular insertion hole is 5-8mm; the diameter of the small-diameter end of the tapered through hole is 12mm.

[0011] As a preferred embodiment of this utility model, the distance between the large-diameter end of the tapered through hole and the adjacent rectangular insertion hole is 10-16mm; the diameter of the large-diameter end of the tapered through hole is 18-20mm.

[0012] As a preferred embodiment of the present invention, the insert plate includes a rectangular insert plate portion; one end of the rectangular insert plate portion is provided with a handle plate; the other end of the rectangular insert plate portion is provided with a pointed cone structure.

[0013] As a preferred embodiment of this utility model, a pair of opposing L-shaped guide strips are fixed on the surface of the breeding tray at the large-diameter end of the conical through hole; the insert plate is inserted into and cooperates with the two L-shaped guide strips.

[0014] This utility model has the following beneficial effects:

[0015] 1. This invention utilizes a rectangular array of conical through-holes to sample and cultivate a large number of corn seeds simultaneously, significantly improving detection efficiency. Compared to traditional methods, this device reduces the tedious process of processing seeds individually, making batch testing possible.

[0016] 2. The small-diameter end design of the conical through-hole in this invention ensures stable placement of a single seed, avoiding detection errors caused by multiple seeds crowding into the same hole. Simultaneously, the combined use of the insert plate and L-shaped guide strip achieves precise seed positioning and stable fixation, further guaranteeing the accuracy of the test results.

[0017] 3. The design of the insert plate in this utility model includes a handle and a pointed cone structure, which allows operators to easily grip and move the insert plate, while reducing damage to seeds during insertion and removal. The L-shaped guide strip also simplifies the insertion process and improves the ease of operation.

[0018] 4. This invention simultaneously and randomly samples corn seeds from multiple breeding trays to cultivate them, and calculates the seed germination rate and average germination rate of each breeding tray, which can effectively improve the reliability and representativeness of the test results. This method reduces the random errors that may exist due to a single breeding tray, making the test results more accurate and reliable.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[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 scope of protection of the present utility model. Specific Implementation Example 1:

[0031] Please see Figure 1-6As shown, this utility model is a corn seed germination rate detection device, including a breeding tray 1 and multiple insert plates 2. The breeding tray 1 has a rectangular array of conical through holes 11 for placing corn seeds. Two rectangular insertion holes 12 perpendicular to the axis of the conical through holes 11 are opened on one side of the breeding tray 1 to facilitate the insertion and operation of the insert plates 2.

[0032] The distance between the small-diameter end of the conical through-hole 11 and the adjacent rectangular insertion hole 12 is set at 5-8mm, and the diameter of the small-diameter end of the conical through-hole 11 is 12mm, which is suitable for the stable placement of a single corn seed. At the same time, the distance between the large-diameter end of the conical through-hole 11 and the adjacent rectangular insertion hole 12 is set at 10-16mm, and the diameter of the large-diameter end of the conical through-hole 11 is set at 18-20mm, which can be adjusted according to actual needs to accommodate seeds of different sizes or cultivation requirements.

[0033] The insert plate 2 includes a rectangular insert plate part 21, one end of which is provided with a handle plate 22 to facilitate the operator to grip and move the insert plate; the rectangular insert plate part 21 is provided with a pointed cone structure at the other end to reduce damage to the seeds and improve the accuracy of operation during insertion and removal.

[0034] A pair of opposing L-shaped guide strips 13 are fixed on the surface of the breeding tray 1 at the large-diameter end of the conical through hole 11. These guide strips guide the insertion direction of the insert plate 2, ensuring that the insert plate can be accurately and stably inserted into the designated position. The insert plate 2 engages with the two L-shaped guide strips 13 to achieve precise positioning and stable fixation of the insert plate.

[0035] The corn seed germination rate testing device involves four processes: seed collection, seed placement, seed turning, and seed breeding.

[0036] During the seed collection process, the first insert plate 2 is inserted into the conical through hole 11 adjacent to the small diameter end of the breeding tray 1. The whole tray is placed in the seed pile, and the seeds cover the small diameter end of the breeding tray 1. Then, the second insert plate 2 is used to scrape the surface of the small diameter end of the breeding tray 1 flat and discharge the remaining seeds. Each conical through hole 11 stores one corn seed at its small diameter end.

[0037] During the seeding process, the second insert plate 2 is inserted between the two L-shaped guide strips 13 to block the conical through hole 11 at the large diameter end of the breeding tray 1. Then, the first insert plate 2 is pulled out, and the corn seeds located at the small diameter end of the conical through hole 11 fall to the large diameter end under the action of gravity. Then, the first insert plate 2 is inserted into the adjacent conical through hole 11 at the large diameter end of the breeding tray 1 to prepare for the next turnover operation.

[0038] During the flipping process, the seed tray 1 and insert plate 2, which have undergone the seed-laying process, are flipped over so that the larger diameter end of the conical through hole 11 faces upwards. Then, the second insert plate 2 is pulled out to expose the corn seeds, facilitating subsequent breeding operations.

[0039] During the breeding process, the corn seeds with 11 large-diameter holes in the conical tray are covered with potting soil and watered to keep the soil moist. Then, a damp cloth is placed over the seeds to maintain stable humidity and temperature in the breeding environment. Finally, the breeding tray is placed in a temperature- and humidity-controlled incubator to await seed germination.

[0040] Seven days later, remove the breeding tray 1 from the incubator, uncover the cover, count the ungerminated seeds N, and the number of conical holes 11 in the breeding tray 1 M. According to the formula: the germination rate of a seed in a breeding tray 1 P = (MN) / M, the germination rate of this batch of corn seeds can be calculated.

[0041] Multiple breeding trays 1 are simultaneously and randomly sampled to cultivate corn seeds. The germination rate of seeds in each breeding tray 1 is calculated, and the average germination rate is calculated, which can improve the accuracy of the detection structure of the germination rate of this batch of corn seeds.
