Abstract

A plant growth accelerator includes a negative voltage device with a negative voltage generator. A negative electrode is electrically connected to an output terminal of the negative voltage generator. The negative electrode is configured to directly or indirectly connect to plants.

Claims (27)

1 . A plant growth accelerator, comprising:

a negative voltage device, wherein the negative voltage device comprises a negative voltage generator configured to produce a negative high-voltage microcurrent continuously adjustable from −1 kV to −5 kV; and

a negative electrode electrically connected to an output terminal of the negative voltage generator, wherein the negative electrode is configured to be directly or indirectly connected to plants;

wherein the plant growth accelerator has a plant connection configured for connecting the negative voltage generator to the plants, the plant connection consisting of the negative electrode.

2 . The plant growth accelerator according to claim 1 , wherein the negative voltage device further comprises a power supply assembly, and the power supply assembly comprises a power supply, wherein the power supply is electrically connected to the negative voltage generator.

3 . The plant growth accelerator according to claim 2 , wherein the negative voltage device further comprises a housing, and the negative voltage generator is disposed inside the housing.

4 . The plant growth accelerator according to claim 3 , wherein the power supply assembly further comprises a solar panel, which is mounted on the housing, wherein the solar panel is electrically connected to the power supply.

5 . The plant growth accelerator according to claim 4 , wherein a protective plate is slidably disposed inside the housing and fits against the solar panel.

6 . The plant growth accelerator according to claim 3 , wherein a USB charging interface is provided on an outer side of the housing.

7 . The plant growth accelerator according to claim 3 , wherein a switch electrically connected to the negative voltage generator is provided on the outer side of the housing.
