Embodiment 1

[0020]The invention relates to a plant sound frequency regulation and adaptive system, which is characterized in that it mainly includes a biochemical sensor group, a chip, a frequency generator, a power amplifier unit and a speaker; the biochemical sensor group is used for real-time acquisition of external environmental factor data in the area where the system is located; a chip Based on the external environmental factor data collected by the biochemical sensor group, the plant spontaneous sound frequency, that is, the frequency acting on the plant, is obtained through the calculation formula of the influence relationship between the plant spontaneous sound frequency and the external environmental factor, and is sent to the frequency generator. The frequency generator is used to modulate the corresponding sound wave frequency digital signal and send it to the power amplifier unit; the power amplifier unit is used to output the audio signal to the speaker according to the modula...

Embodiment 2

[0048] This embodiment relates to the plant sound frequency regulation and adaptive method of the system described in Example 1, and the specific steps include: first, the plant spontaneous sound frequency data and the plant spontaneous sound frequency corresponding to the factors of air temperature, air humidity, light intensity and soil moisture content The calculation formula of the influence relationship with the external environmental factors is written into the programmable chip; then, the biochemical sensing technology is used to detect the air temperature, air humidity, light intensity and soil moisture content of the external environmental factors, and the detection data is transmitted in real time into The chip, and then the chip calculates according to the calculation formula of the relationship between the spontaneous sound frequency of the plant and the external environmental factors, obtains the frequency of the sound wave acting on the plant, and sends the frequen...

Embodiment 3

[0051] This experimental example is the application of the method described in Embodiment 1 and the system described in Embodiment 2 in the field of the Yellow River Delta Agricultural High-tech Industrial Demonstration Zone in Dongying City. The scope of the experimental field is 660m long from north to south and 100m wide from east to west, and the planting plants are selenium-enriched soybeans. The experimental equipment adopts the unidirectional cuboid equipment described in Example 2, the size of the equipment is 40cm×50cm×80cm, the output volume is 110db, and the output frequency is regulated in real time according to the external factors. The equipment is arranged 50 meters away from the southern headland, and a speaker is set to the north. The processing time is from early July to mid-October 2021, about three and a half months. 3 hours from 12:00 to 12:00. The control group was a bean field at a distance of 500m from the equipment, and the control group did not perfo...
