Abstract
Description
Technical Field
[0001] The invention relates to the technical field of rice breeding, and in particular to a breeding method for rice resistant to stripe disease. Background Art
[0002] The steps of rice seedling cultivation include: seed selection, seed soaking, preparation of seedling beds, sowing, management and transplanting.
[0003] The purpose of soaking seeds is to make the seeds absorb water faster and reach a moisture content that allows normal germination. The moisture content of dry seeds is usually below 15%, and the physiological activity is very weak, and they are in a dormant state. After the seeds absorb water, the seed coat swells and softens, and the oxygen dissolved in the water enters the cells along with the water, and the enzymes in the seeds begin to activate. Due to the action of the enzymes, the respiration of the embryo is enhanced, and the insoluble substances stored in the endosperm are gradually transformed into soluble substances and transported to the embryo along with the water. The embryo obtains water, energy and nutrients, and under suitable temperature and oxygen conditions, the cells begin to divide, elongate, and break through the husk (germination).

[0023] Specifically, during seed soaking, after the soaking operation of the rice seeds is completed, the delivery pump 404 and the drive motor 405 are started, and the drive motor 405 drives the drive gear 406 to rotate. Since the drive gear 406 is meshed with the gear frame 421, the drive motor 405 drives the gear frame 421 to rotate, and then the gear frame 421 drives the fixed frame to rotate. At this time, as the fixed frame 409 rotates, the transmission gear 412 can be driven to operate, and since the transmission gear 412 is meshed with the fixed gear ring 401, the transmission gear 412 drives the shaft member 413 to rotate, and then cooperates with the connecting rod 415 and the linkage plate 414 to make the movable block member 416 move on the guide rod 420.

In a specific application scenario, the seed soaking intermittent module 6 is suitable for the rice seed soaking process, that is, the seed soaking intermittent module 6 can intermittently lift the rice seed frame 3 when in use, so as to facilitate the activation of the rice seeds, and when performing the intermittent lifting, the device can automatically lift the rice seed frame 3 at a fixed time, thereby increasing the automation effect of the device when in use, thereby eliminating the need for staff to perform intermittent operations at regular intervals, thereby increasing the convenience of use of the device when in use, and reducing the work intensity of the staff, and the lifting of the seed soaking intermittent module 6 facilitates the rinsing after soaking, thereby improving the diversity of use of the device and the coordination between the operation modules.
[0026] Working principle: When in use, the motor 1 602 drives the power supply part 613 to rotate over time. When a certain time is reached, the power supply contact 614 on the power supply part 613 contacts the power supply contact 614 on the power connection part 615, so that the power connection part 615 is energized, and then the motor 2 616 is energized through the connecting circuit 617. At this time, the motor 2 616 drives the transmission wheel 611 and the transmission belt 603 to run, and then drives the winding disk 604 to tighten the connecting cable 605, so that the rice seed frame 3 is lifted, so as to perform the seed soaking interval. During the seed soaking interval, the stirring pipe 411 runs and rotates. At the same time, the air pump 419 is running to fully spread the rice seeds for intermittent soaking. After the soaking interval, the motor 1 602 drives the power supply component 613 to continue to rotate, so that the power supply connector 614 on the power supply component 613 is separated from the power supply connector 614 on the power connection component 615, so that the motor 2 616 is powered off, and then the rice seed frame 3 falls to the inside of the soaking bin 2 with gravity to continue soaking. During soaking, after the soaking operation of the rice seeds is completed, the delivery pump 404 and the drive motor 405 are started, and the drive motor 405 drives the drive gear 406 to rotate. Since the drive gear 406 is meshed with the gear frame 421, the rice seed frame 3 is driven to rotate. , so that the driving motor 405 drives the gear frame 421 to rotate, and then the gear frame 421 drives the fixed frame to rotate. At this time, as the fixed frame 409 rotates, the transmission gear 412 can be driven to operate, and because the transmission gear 412 is meshed with the fixed gear ring 401, the transmission gear 412 drives the shaft member 413 to rotate, and then cooperates with the connecting rod 415 and the linkage plate 414 to make the movable block 416 move back and forth on the guide rod 420. At the same time, the delivery pump 404 delivers the water in the water tank 9 to the inside of the fixed pipe 407 through the connecting pipe 8, and The conveyor belt further connects the interior of the bin 423 and then transports the water to the interior of the flushing bin 424 through the flushing pipe 425. At this time, as the movable block 416 moves, the cleaning nozzle 426 sprays water to flush the rice seeds. At the same time, as the fixed frame 409 rotates, the fixed frame 409 can drive the fixed sleeve rod 422, the air pump 419, the connecting pipe 417 and the stirring pipe 411 to rotate, thereby stirring the rice seeds. At the same time, the air pump 419 is started so that the stirring pipe 411 blows up the inside of the rice seed frame 3 while stirring, so that the rice seeds are distributed loosely until the soaking and flushing are completed.
