Problems solved by technology

However, the slope soil that has just been planted and transplanted cannot be effectively consolidated. It must be effective after the plant root system has grown and formed. During this period, only some geotextiles can be used for auxiliary reinforcement, but it is very easy to cause water and soil erosion after being washed by rainwater. , resulting in weakened reinforcement effect
There are also plants whose leaves grow fast but have short and shallow root systems, and the effect of stabilizing the soil is poor, and the growth speed does not match the effect of stabilizing the soil

Embodiment 1

[0037] Embodiment 1: as Figure 1~2 As shown, a plant root growth rate measurement device includes a culture container 1 and a deformation container 2 arranged inside the culture container 1, and the pressure on the inner wall of the deformation container 2 is measured by a pressure measurement mechanism. Drainage holes may be provided at the bottom of the culture container 1 .

[0038] In this embodiment, the deformation container 2 is an air bag arranged in the culture container 1 in a ring shape.

[0039] The gas is connected with a gas volume measuring instrument 3, and the pressure measuring mechanism is an air bag manometer 4.

[0040] In this embodiment, the culture container 1 can be provided with a transparent material, such as glass or acrylic, and the airbag is made of transparent plastic, which is convenient for observing the growth of the root system.

[0041] The measurement method is as follows: step 1, set the air bag in the cultivation container 1, then plan...

Embodiment 2

[0049] Embodiment 2: as different from Embodiment 1 Figure 3-6 As shown, the culture container 1 includes a bottom plate 101 and a limit cylinder 102 set on the outside of the deformation container 2. The deformation container includes several unit bodies, and the unit bodies include a first rotating body and a second rotating body. The first rotating body Including a first web 201, one side of the first web 201 is provided with a first rotating shaft 202, and the other side is provided with a first sleeve 203, the second rotating body includes a second web 204, the second web 204 One side is provided with a second rotating shaft 205, and the other side is provided with a second sleeve 206. The first rotating shaft 202 is inserted in the second sleeve 206 of the second rotating body adjacent to it, and the second rotating shaft 205 is inserted in the Inside the first sleeve 203 of the first rotating body adjacent to it, the first sleeve 203 is fixed on the bottom plate 101 of...

Abstract

The invention provides a plant root system growth rate measurement device and measurement method. The measurement device comprises a culture container and a deformation container arranged on the innerside of the culture container, wherein the pressure of the inner wall of the deformation container is measured through a pressure measurement mechanism. The plant root growth rate measurement devicecomprises the culture container and the deformation container arranged on the inner side of the culture container, wherein the pressure of the inner wall of the deformation container is measured through the pressure measurement mechanism. According to the device and the method, the plant root growth rate can be measured, so that the plant with the optimal growth rate in the same soil or the soil variety with the most suitability for root growth of plants can be selected.

Description

technical field [0001] The invention relates to the technical field of plant growth experiments on ecological slopes, in particular to a plant root growth rate measurement device and a measurement method. Background technique [0002] Ecological slope is a relatively new slope reinforcement method, which is widely used in construction, highway, water conservancy and other projects. Its characteristic is to use the plant root system to stabilize the soil instead of the traditional slope reinforcement method. In engineering practice, ecological slopes are usually planted with grass spraying and artificial transplanting. However, the slope soil that has just been planted and transplanted cannot be effectively consolidated. It must be effective after the plant root system has grown and formed. During this period, only some geotextiles can be used for auxiliary reinforcement, but it is very easy to cause water and soil erosion after being washed by rainwater. , resulting in wea...
