Description

Technical Field

[0001] The invention relates to the technical field of sowing test, in particular to a method and a device for measuring cotton seed vitality. Background Art

[0002] Cotton seed vigor can more accurately reflect the field emergence rate of seeds than germination rate. By measuring the vigor of cotton seeds, the emergence of seeds in the field environment can be more accurately predicted, which is of great significance for ensuring the high yield and stability of crops. By measuring the vigor of seeds, the germination potential of seeds can be understood, so as to make rational use of seed resources. For those seeds with low germination rate but high vitality, the emergence rate can be improved by sowing after appropriate treatment; for those seeds with low germination rate and vitality, they should not be used as seeds.

[0003] In the prior art, the viability determination schemes for cotton seeds include the double-layer filter paper germination method, the TTC staining method, and the low-temperature germination method. The low-temperature germination method uses germination paper to wrap multiple seeds to be tested and then place them in a constant temperature and light environment for cultivation. However, since each measurement requires a fixed number of seeds to be tested that are equally spaced, the preliminary preparation steps are cumbersome. On the other hand, after the germination paper is wound and placed inside the light box, since the seeds are evenly distributed in the cylindrical paper tube at this time, there is a difference between the air permeability of the inner layer and the outer layer, and there is also a difference in the light effect between the bottom layer seeds and the top layer seeds. Therefore, this determination scheme cannot accurately simulate the germination situation during actual planting. Summary of the invention

The whole process can be quickly and evenly quantitatively processed with the help of the metering and placing mechanism, and the excess seeds can be glued, pulled out and recycled, thereby improving the efficiency of metering and placing. The germination paper can be rolled up in conjunction with the winding assembly, and air flow can be transported from the inside and clean water can be sprayed in, so that the seeds wound and clamped by the inner and outer layers are subjected to uniform moisture and light conditions in the subsequent cultivation process.

[0036] When the present invention is used, two rolls of germination paper are respectively installed inside the corresponding winding columns, and a large number of seeds to be tested are put into the storage bin 23, and a fixed number of seeds to be tested are transported to the surface of the metering and placing mechanism 3 through the storage bin 23; the two rolls of germination paper are pulled, and one end is plugged with one of the winding assemblies 4, and with the help of the rotatable pressing plate 36 on the winding assembly 4; at the same time, the ends of the two germination papers are clamped and locked on the surface of the winding assembly 4; the metering and placing mechanism 3 is started, and with the help of the operation of the motor 18, the seeds to be tested are quantitatively processed through the metering and placing mechanism 3, and the quantitative seeds are placed on the surface of the bottom germination paper 15, and the winding assembly 4 is manually rotated to roll up the double-layer germination paper; after winding a fixed number of cotton seeds, the germination paper area where no seeds are placed is cut, and the winding assembly 4 is moved to the inside of the light box 2; the cultivation is carried out for 5 days according to 10 hours of light every day, and water mist is sprayed regularly, and finally the seeds are taken out to observe the germination state, and the proportion data between the germinated seeds and the total amount of seeds is calculated.

[0038] Specifically, the top metering and placing mechanism 3, the light box 2, multiple winding assemblies 4 and two winding columns are supported by the bottom plate 5, and the rolled germination paper is wound on the two winding columns, and the two rolls of germination paper are guided by the guide rods, so that after a fixed number of seeds to be tested are transported to the bottom germination paper 15 through the metering and placing mechanism 3, the winding assembly 4 can be manually rotated to reel in one end of the two layers of germination paper. When reeling in, the seeds after metering and placing in the middle can be rolled into the inner side of the paper tube for placement. The groove 11 at the bottom can be used to avoid being blocked and squeezed by the bottom plate 5 as the paper tube gradually becomes thicker during the reeling process, ensuring that the paper tube always remains in a relaxed state.

[0039] In this embodiment, the metering placement mechanism 3 includes a motor 18, a metering sleeve 19 and a pressing guide roller 21. The output end of the motor 18 is inserted with a drive shaft 27, and the metering sleeve 19 is installed on the surface of the drive shaft 27.

The bottom of the storage bin 23 is against the surface of the metering sleeve 19, the surface of the pressing guide roller 21 is attached with an adhesive layer 22, the surface of the adhesive layer 22 is in contact with the surface of the metering sleeve 19, a return shovel plate 24 is welded on one side of the top of the storage bin 23, and a retaining bar 25 is attached to the side of the return shovel plate 24 and the top of the storage bin 23, and the edge of the return shovel plate 24 is against the top of the pressing guide roller 21. The seeds to be tested are evenly distributed and placed on the surface of the bottom germination paper 15 by the metering placement mechanism 3, and the seeds to be tested are clamped in the middle of the germination paper by pulling the ends of the germination paper at the same time. The whole process can be quickly and evenly quantitatively processed with the help of the metering placement mechanism 3, and the excess seeds can be bonded, pulled out and recycled, which improves the efficiency of metering placement.

[0040] Specifically, after starting the motor 18, the motor 18 drives the drive shaft 27 to rotate, and the drive shaft 27 drives the metering sleeve 19 on the surface to rotate. After the seeds to be tested inside the storage bin 23 fall toward the bottom, they will enter the inside of the metering hole 26. With the rotation of the metering sleeve 19, the seeds to be tested that have entered the inside of the metering hole 26 can be finally transported to the bottom moving bottom germination paper 15. At the same time, the pressing guide roller 21 is also driven to rotate with the help of the driving gear 28, the toothed belt 29 and the driven gear 30. With the help of the adhesive layer 22 on the surface of the pressing guide roller 21, a part of the seeds stacked inside the metering sleeve 19 are pasted and pulled out.

[0041] In this embodiment, the winding assembly 4 includes a winding sleeve 31 and a pressing plate 36. A connecting pipe 32 is integrally formed at both ends of the winding sleeve 31. An opening 33 is provided at one end of the connecting pipe 32, and the connecting pipe 32 is embedded in the interior of the slide groove 13. A rotating ring 35 is sleeved on the surface of the connecting pipe 32. A linkage arm 37 is integrally formed on the side of the rotating ring 35. The pressing plate 36 is integrally formed at the end of the linkage arm 37. A plug-in slot 34 is provided on the surface of the winding sleeve 31.

[0042] Specifically, after the ends of the two germination papers are inserted into the plug-in slot 34, the pressing plate 36 is rotated to cover the surface of the plug-in slot 34. At this time, the rubber clip 38 can be embedded in the plug-in slot 34, so that the ends of the two germination papers are squeezed and fitted together. Subsequently, the winding sleeve 31 is manually rotated to synchronously wind the top germination paper 16 and the bottom germination paper 15 on the surface of the winding sleeve 31, and the arranged seeds are also wound into the paper tube interlayer.

During the cultivation process, clean water is injected into the interior with the help of the connecting pipe 32, and sufficient air is transported.

[0043] This embodiment also provides a determination method using the above determination device, comprising the following steps:

[0044] Step 1: install two rolls of germination paper into the corresponding winding columns, and put a large number of seeds to be tested into the storage bin 23, and transport a fixed number of seeds to be tested to the surface of the metering placement mechanism 3 through the storage bin 23;

[0045] Step 2: Pull two rolls of germination paper and plug one end into one of the winding assemblies 4, and use the rotatable pressing plate 36 on the winding assembly 4;

[0047] Step 4: Place the quantitative seeds on the surface of the bottom germination paper 15, and manually rotate the winding assembly 4 to roll up the double-layer germination paper;
