Device for observing activity rule of underground pests in soil

Abstract

The invention provides a device for observing the activity rule of underground pests in soil. The device comprises a box and a thermal insulation door and is characterized in that the box is producedby thermal insulation materials and provided with an opening in the top, the inner cavity of the box is used for accommodating soil allowing the underground pests to live in, and at least one side ofthe box is provided with a transparent plate with scale marks used for determining distance between the underground pests and the soil surface; the thermal insulation door is movably mounted on the box or the transparent plate and can be driven to move between a closing position and an opening position under force, and when the thermal insulation door is located at the closing position, the thermal insulation door attaches to the outer side of the transparent plate to prevent heat exchanging between the interior of the box and the exterior of the box through the transparent plate; when the thermal insulation door is located at an opening position, the thermal insulation door is away from the transparent plate, an operator can conveniently observe the underground pests in the box through the transparent plate. By the device suitable for observing the activity rule of the underground pests, the soil environment for underground pest living can be simulated.

Description

technical field [0001] The invention relates to an observation device, in particular to a device for observing the law of activity of underground pests in soil. Background technique [0002] Underground pests refer to a class of pests that live in the soil and damage the underground parts of crops. They are the most diverse, most diverse, most adaptable, and most harmful pest groups among crop pests, including scarabs, beetles, and needle beetles. , root weevil, termites, etc. It mainly damages larvae (nymphs), and some types of adults can also cause damage. It mainly feeds on the seeds, young shoots and rhizomes of harmful crops, causing problems such as lack of seedlings and broken ridges, reduced production and harvest, and reduced quality of crops, resulting in huge economic losses. Because they mainly live underground, their activities are hidden and difficult to find. Once the crops show symptoms of damage, it will be too late. Therefore, the effective prevention and...

AI Technical Summary

Problems solved by technology

However, because underground pests live in the soil for a long time, it is difficult to observe the activities of underground pests; some observation devices in the prior art are usually used to observe the growth of insects on the ground, which cannot simulate the living environment of underground pests. It is suitable for the observation of underground pests, therefore, it is necessary to provide a device for observing the activity of underground pests in the soil
