The application belongs to the field of agricultural chemistry, and particularly relates to an activator based on structural modification of L-methionine and a synthesis method and application thereof; the application takes L-methionine as a core raw material, which is of natural origin, cheap and easy to obtain and excellent in biocompatibility, and performs structural modification through one-step esterification to synthesize a target compound 2-(diethylamino)ethyl-L-methionine ester; biological activity experiments prove that the compound can effectively promote the germination rate of crops at a low concentration, significantly optimize the growth state of roots and stems, and greatly enhance the stress resistance potential of seedlings; in addition, the compound has outstanding industrialization advantages, and is simple in production process, controllable in raw material cost and excellent in water solubility, with a solubility in water of greater than or equal to 30 g / L at 25 DEG C, so that it can be mass-produced without complex post-treatment, thereby not only effectively reducing the input cost of agricultural production, but also significantly improving the yield and quality of crops, and providing a new path for the development of green and environmentally-friendly plant growth activators.

The application discloses an agricultural automatic seeding system and device, and relates to the technical field of agricultural seeding; the agricultural automatic seeding system comprises the following steps: S1, first, a soil turning mechanism is started to break up the clods in the soil of the land to be seeded, so that the soil is loose and is convenient for cultivation; S2, a feeding and conveying mechanism is used to convey the seeding seeds from a chute to a conveying pipe one by one; S3, a seeding and soil covering mechanism is used to seed and cover the soil at the same time; and S4, an indirect liquid spraying mechanism is used to spray a seed germination accelerating agent on the seeded seeds; the seeding and soil covering mechanism, the indirect liquid spraying mechanism, the feeding and conveying mechanism and the soil turning mechanism are used, first, the soil turning mechanism is used to turn up the land to be planted, so that the seeding is convenient; the feeding and conveying mechanism is used to convey the seeds to the seeding and soil covering mechanism, the soil covering mechanism is used to dig a pit, then the seeds are seeded, and after the seeds are seeded, the surrounding miscellaneous soil is pushed into the pit to bury the seeds.
