Description

Technical Field

[0001] The utility model relates to the technical field of vegetation experiments, in particular to a vegetation drought resistance recovery experiment device. Background Art

[0002] Soil drought is the harm caused by the lack of water in the soil, and the plant roots cannot absorb enough water to compensate for the transpiration consumption; atmospheric drought is that the air is dry and often accompanied by a certain wind force. Although the soil is not short of water, due to strong transpiration, the plant is short of water supply and forms harm. The arid climate in grassland areas will damage the vegetation, exacerbate the degree of grassland desertification, and damage the ecological system. The drought conditions in different regions are also different. Therefore, different types of drought-resistant vegetation need to be planted in different regions, so drought resistance recovery experiments are carried out on various vegetations.

[0003] In the prior art, when conducting a drought resistance recovery experiment on vegetation, it is necessary to actually place the vegetation in a drought state for several days or even longer. In particular, it is necessary to wait for the water in the vegetation planting substrate to naturally consume and evaporate. The experimental waiting time is relatively long and the experimental efficiency is relatively low. Therefore, a vegetation drought resistance recovery experiment device is designed to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model aims to solve at least one of the technical defects.

[0005] For this reason, an object of the utility model is to provide a vegetation drought resistance recovery experiment device to solve the problems mentioned in the background art and overcome the deficiencies in the prior art.

[0006] To achieve the above object, an embodiment of one aspect of the utility model provides a vegetation drought resistance recovery experiment device, including a base, a support rod, and a top ring. A circle of support rods is fixedly connected to the top surface of the base, and the top ends of the support rods are fixedly connected to the top ring.

[0007] A ribbed ring is placed above the top ring, and a matrix cage is fixedly connected to the bottom of the ribbed ring.

[0008] A first handle is fixedly connected to the top of the top ring, and a second handle is fixedly connected to the top of the ribbed ring.

[0009] The matrix cage is located inside the top ring and the base.

[0010] A temperature adjustment knob is installed on the side of the top ring, and a plurality of electric heating rods are fixedly connected to the bottom of the top ring. The electric heating rods are located outside the matrix cage.

[0011] Preferably, according to any of the above solutions, the top surface of the base is perpendicular to the support rod, and the interval angle of the support rods is ninety degrees.

[0012] Adopting the above technical solution: This device is dedicated to the experiment on the drought resistance recovery ability of vegetation. A single device corresponds to a single plant of vegetation.

[0013] This device is divided into two major parts. The first part is the external part, which consists of a base, a support rod, a top ring, a first handle, a temperature control knob, and an electric heating rod.

[0014] The second part is the internal part, which consists of a ribbed ring and a matrix cage.

[0015] Preferably, according to any of the above solutions, the bottom surface of the top ring is welded to the top end of the support rod, and the ribbed ring is welded to the matrix cage.

[0016] Adopting the above technical solution: The core structure of this device is: a base, a support rod, a top ring, a ribbed ring, a matrix cage, a first handle, a second handle, a temperature control knob, and an electric heating rod.

[0017] The core advantages of this device are as follows: The soil planting matrix is filled into the matrix cage. The matrix cage and the ribbed ring are integrated. The vegetation is planted in the matrix. The ribbed ring is directly hung on the top ring. The matrix cage enters the inner side of the top ring. The design of the ribbed ring in cooperation with the second handle enables the vegetation to be loaded and unloaded from this device more conveniently. This design enables quick completion every time when replacing or adjusting the vegetation sample, reducing the experimental preparation time.

[0018] This device is divided into an internal part and an external part. The external part is the main body of the device, and the internal part is the matrix cage, which is specially used for planting vegetation. The main body of the external device consists of three parts: a base, a support rod, and a top ring. Technicians can clearly see the state of the soil matrix in the matrix cage, that is, the drought state, through the gap of the support rod, and can have a relatively clear judgment on the test situation.

[0019] On the device main body, that is, between the base and the top ring, a plurality of electric heating rod structures are designed, which are uniformly controlled by the temperature control knob, and the temperature is controllable. When it generates heat, it can heat the soil matrix in the matrix cage, enabling its moisture to evaporate quickly, increasing its drought speed, so as to shorten the test time and improve the test efficiency. Compared with the drought simulation under natural conditions, the electric heating rod heating system can reach the required drought degree more quickly, enabling the test to be completed in a shorter time. This not only improves the test efficiency but also reduces the uncertain factors that may be brought about by long-term waiting.

[0020] The temperature control knob has a current regulation function. By rotating the knob to different gears, the magnitude of the current passing through the heating wire of the electric heating rod can be changed, thereby adjusting the heat generation of the heating wire. The larger the current, the greater the heat generation of the heating wire; the smaller the current, the smaller the heat generation of the heating wire, so as to realize the temperature regulation of the electric heating rod.

[0025] 1. For this vegetation drought resistance recovery test device, through the cooperative setting of the base, support rods, top ring, rib ring, matrix cage, first handle, second handle, temperature control knob, and electric heating rod, the soil planting matrix is filled into the matrix cage.

The design of the rib ring cooperating with the second handle enables the vegetation to be loaded and unloaded from this device more conveniently. This design enables quick completion every time when replacing or adjusting the vegetation sample, reducing the experimental preparation time.

[0026] This device is divided into two parts, an external part which is the device main body and an internal part which is the matrix cage specifically for planting vegetation. The external device main body consists of a base, support rods, and a top ring. Technicians can clearly see the state of the soil matrix in the matrix cage, that is, the drought state, through the gaps between the support rods, and can have a relatively clear judgment on the test situation.

For this vegetation drought resistance recovery test device, multiple electric heating rod structures are designed between the base and the top ring of the device main body and are uniformly controlled by the temperature control knob. The temperature is controllable. When it generates heat, it can heat the soil matrix in the matrix cage, enabling the water in it to evaporate quickly, increasing its drought speed, so as to shorten the test time and improve the test efficiency.
