Description

Technical fields:

[0001] This utility model relates to the technical field of root observation equipment, and in particular to a novel plant root observation device. Background technology:

[0002] In-situ root systems refer to the root structure of plants in their natural growth environment without damage. Studying these root systems can directly reflect the true state of plant interaction with the environment. Roots are important organs for plants to absorb water and anchor the plant. Traditional research often obtains root systems through excavation, but this method damages the soil structure and leads to data distortion. Therefore, non-destructive observation methods have gradually become mainstream, such as the glass wall method, the endoscopic tube method (micro-root tube), and the container method. Among them, the endoscopic tube method uses a soil drill to make a hole on one side of the plant and inserts a glass tube into the soil for observation. The tube wall above the ground is covered with a metal foil to block light, and a reflector and a light are installed inside the tube. However, the disadvantage of this method is that it requires carrying an additional drill bit to make the hole and additional light blocking treatment, making the operation cumbersome and complicated. Therefore, this utility model designs a new plant root observation device. Utility model content:

[0003] The purpose of this invention is to provide a novel plant root observation device to solve the technical problem of the complex operation of the endoscopic tube method for observing roots.

[0004] The utility model relates to a novel plant root observation device, comprising a vertically arranged cone with a pointed bottom. A window is provided on the outer wall of the cone, and a glass tube is installed inside the cone to seal the window. A copper wire is vertically arranged inside the cone, and an insulating sleeve is fitted over the copper wire. An observation mirror is connected to the bottom end of the copper wire at an angle downwards, with the mirror surface facing the window. A lighting lamp is provided above the observation mirror and is electrically connected to the copper wire. The other end of the copper wire is electrically connected to a power source.

[0005] Furthermore, a retaining ring is installed on the inner wall of the cone, the retaining ring being located below the window, and a screw cylinder is screwed into the cone, with the glass cylinder located between the retaining ring and the screw cylinder.

[0006] Furthermore, sealing gaskets are installed between the retaining ring and the glass cylinder, and between the glass cylinder and the screw cylinder.

[0007] Furthermore, a cover plate is fixedly installed at the top of the screw barrel, and an observation through hole is opened at the center of the cover plate, with a T-shaped plug inserted into the observation through hole.

[0008] Furthermore, an installation through hole is provided on the cover plate, and the copper wire is inserted into the installation through hole. A fastening screw hole is provided on the outer wall of the cover plate, and the fastening screw hole is connected to the installation through hole. A fastening screw is screwed into the fastening screw hole.

[0009] Furthermore, the cone, the screw, the cover plate, and the T-plug are all made of stainless steel.

[0010] The beneficial effects of this utility model are as follows: This utility model has a simple structure and uses a stainless steel cone that can be directly anchored into the soil without the need for additional drill bits. It also has a built-in light-shielding function, is strong and not easily broken, and can be reused. In addition, a detachable glass tube is designed inside the cone for observation, which makes implementation more time-saving, labor-saving, quick and convenient, and is worthy of widespread promotion and use.

Detailed implementation method:

[0016] like Figures 1 to 3 As shown, a novel plant root observation device includes a vertically arranged cone 1 with a pointed cone-shaped bottom. A window 2 is provided on the outer wall of the cone 1. A glass tube 3 is installed inside the cone 1, sealing the window 2. A copper wire 7 is vertically arranged inside the cone 1, and an insulating sleeve 11 is fitted over the copper wire 7. An observation mirror 9 is connected to the bottom end of the copper wire 7 at an angle downwards, with the mirror surface of the observation mirror 9 facing the window 2. An illumination lamp 8 is arranged above the observation mirror 9 and is electrically connected to the copper wire 7. The other end of the copper wire 7 is electrically connected to a power source.
