Embodiment 1

[0020]The invention relates to a plant audio-frequency regulation 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 loudspeaker; the biochemical sensor group is used for real-time collection of external environmental factor data in the area where the system is located; the chip According to the external environmental factor data collected by the biochemical sensor group, the plant spontaneous sound frequency is obtained through the calculation formula of the influence relationship between the plant spontaneous sound frequency and the external environmental factors, that is, the frequency acting on the plant, and 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 mod...

Embodiment 2

[0048] This embodiment relates to the self-adaptive method for plant sound frequency regulation and control of the system described in Embodiment 1. 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 are transmitted in real time into the Chip, and then the chip calculates according to the calculation formula of the influence relationship between the plant's spontaneous sound frequency and the external environmental factors, obtains the sound wave frequency acting on the plant, and sen...

Embodiment 3

[0051] This experimental example is the application of the method described in Example 1 and the system described in Example 2 in the field of the Yellow River Delta Agricultural High-tech Industry Demonstration Zone in Dongying City. The range 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 one-way cuboid equipment described in Example 2, the equipment size is 40cm×50cm×80cm, the output volume is 110db, and the output frequency is adjusted in real time according to external factors. The equipment is arranged 50 meters away from the southern headland, and a speaker is set up to the north. The processing time is from early July to mid-October 2021, about three and a half months. The processing method is once every other day on sunny days, and the processing time is 9 am 3 hours from noon to 12 o'clock. The control group is a soybean field 5...
