Description

Technical Field

[0001] The utility model relates to the technical field of test auxiliary devices, and particularly relates to a rice ridge building device for plot tests. Background Technique

[0002] As one of the most important food crops in China, during the research on its production and planting process, it is often necessary to divide or form fixed test plots. These test plots are essential conditions for agricultural technicians to conduct variety screening, coordinated and efficient utilization of water and fertilizer, and research on pest and disease control.

[0003] Currently, the commonly adopted methods during the test include manually piling up ridges and covering them with films to form fertilizer test plots, pouring cement to form test plots, or inserting simple baffles. However, these methods all have some deficiencies. The first method is cumbersome to operate and requires a large amount of soil to build ridges, which not only reduces the soil in the test plots but also takes a lot of time and effort. The second method is difficult to achieve unified tillage, especially mechanical tillage, which requires soil turning and mixing, and also takes a lot of time and effort. The third method is relatively simple, but the airtightness of the plot is poor, resulting in a decrease in test accuracy. In addition, it is extremely inconvenient for experimenters to walk back and forth in the paddy field during the observation and data investigation process.

[0004] Therefore, in order to solve the above technical problems, there is an urgent need for a lightweight and detachable rice ridge building device for plot tests. Content of the Utility Model

[0005] The purpose of the utility model is to provide a rice ridge building device for plot tests to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Example 1: Please refer to Figures 1 to 7 , a rice ridge-building device for a community experiment, including a ridge-building splicing unit 1. The ridge-building splicing unit 1 includes a ridge body 2 with a hollow interior. The two ends of the ridge body 2 are sealed with end cover plates 3. The outer contour of the ridge body 2 is a long strip structure with a trapezoidal cross-section. The bottom of the ridge body 2 is provided with a vertically downward protruding partition board 4. Both ends of the partition board 4 are provided with outwardly protruding L-shaped bends 5. The upper ends of the L-shaped bends 5 are provided with L-shaped card slots 6 connected to the end cover plates 3. The L-shaped card slots 6 at both ends of the ridge-building splicing unit 1 are in opposite directions and can be inserted into each other. Adjacent ridge-building splicing units 1 are connected by inserting the L-shaped card slots 6 in opposite directions. The bottom of the ridge body 2 is provided with two rows of ground nails 9 arranged on both sides of the partition board 4.

[0031] The working principle of this embodiment:

[0032] In this embodiment, each ridge-building splicing unit 1 is composed of a ridge body 2 with a hollow interior. Both ends of the ridge body 2 are sealed by end covers 3 to form a closed structure to prevent soil erosion. The outer contour of the ridge body 2 is designed as a long strip structure with a trapezoidal cross-section. This design not only ensures the stability of the device but also facilitates fixing and arranging in the paddy field. A partition 4 is provided at the bottom of the ridge body 2, and L-shaped bends 5 and L-shaped slots 6 are provided at both ends thereof. The partition 4 is inserted into the soil to prevent water seepage at the bottom of the ridge body 2. The partition 4 also cooperates with the L-shaped bends 5 and L-shaped slots 6 on both sides thereof to achieve rapid connection and disassembly between the ridge-building splicing units 1. For two adjacent ridge-building splicing units 1, the directions of the L-shaped slots 6 at both ends are opposite, and they can be inserted into each other to form a continuous and stable boundary of the test plot. Ground nails 9 are provided at the bottom of the ridge body 2 to further fix the device in the paddy field soil to ensure stability under conditions such as irrigation and rain erosion. The ground nails 9 are arranged in two rows on both sides of the partition 4, enhancing the overall grip and stability.

[0033] This embodiment adopts a modular splicing design, saving labor and time costs and being extremely convenient for disassembly, facilitating land restoration and reuse after the test; the device has good airtightness and stability, effectively preventing the exchange of water and nutrients between test plots and improving the accuracy and reliability of test data.

The plug 8 on the adjacent ridge-building splicing unit 1 is inserted and matched with the slot 7.

[0035] In this embodiment, the L-shaped slot 6 is inserted and matched with the slot 7 through the plug 8, which is convenient for installation and has a firm connection.

[0036] Embodiment 3: Please refer to Figure 6 , a rice ridge-building device for plot tests, which is different from Embodiment 1 in that a sidewalk 12 is provided on the top of the ridge body 2.

[0037] In this embodiment, by widening the top of the ridge body 2 to form a sidewalk 12, it is convenient for researchers to walk in the test field.
